Do not install the PERFORMANCEPLUS into a common vent with other gasappliances.. This may cause flue gasspillage or appliance malfunction, result-ing in possible severe personal injury,death or substantial property damage.

Removal of an Existing Boiler from aCommon Vent System

For installations in which the PERFOR-MANCE PLUS is replacing an existingboiler / hot water heater system, whichwas connected to a common vent systemwith other appliances, the following stepsshall be conducted with each remainingappliance connected to the common vent-ing system:

1. Any unused openings in the commonventing system must be sealed.

2. A visual inspection of the venting sys-tem must be conducted for proper siz-ing and horizontal pitch. The inspec-tion should ensure no blockage orrestriction is within the vent system,and there is no leakage, corrosion orother items, which could cause anunsafe condition.

3. To adequately test the venting system,close all exterior doors and windowsand all doors between the area contain-ing the remaining appliances connectedto the common vent system and otherareas of the building. Turn on anyclothes dryers and any other gas appli-ance not connected to the common ventsystem. Turn on all exhaust fans, i.e.range hoods and bathroom exhaustfans, preferably at maximum speed.Close any fireplace dampers.

4. Place in operation the first appliancebeing inspected that is connected to thecommon vent system. The remainingappliances should not be in operation.Follow the appliance’s lighting instruc-tions and adjust the thermostat to allowthe appliance to operate continuously.

5. Test for spillage at the draft hood reliefopening after 5 minutes of main burneroperation. Spillage can be detectedusing the flame of a match or candle orwith smoke from a cigarette.

6. Once it has been determined that eachremaining appliance connected to thecommon vent system is properly vent-ed, return doors, windows, exhaustfans, fireplace dampers and any operat-ing gas appliance to their previous con-dition.

Should any improper operation of the commonventing system be detected in the outline test,the condition should be corrected so the ventsystem conforms with the National Fuel GasCode, NFPA 54/ ANSI Z223.1 - latest edition.Canadian installations must conform withB149.1 or 149.2 Installation Code.

Domestic Piping

SECTION IV - Domestic Piping

General Piping Requirements

• All plumbing must meet or exceed alllocal, state and national plumbing codes.

• Use pipe dope or tape suitable forpotable water.

• Use isolation valves to isolate systemcomponents.

• Install unions for easy removal of thePERFORMANCE PLUS from the sys-tem piping.

Domestic Supply Pressure

For applications in which the domestic sup-ply pressure exceeds 70 psig it is recom-mended to install a pressure reducing valveon the cold water supply.

Maintaining the cold water supply at orbelow 70 psig will prevent normal thermalexpansion from repeatedly forcing the T&Prelief valve open.

Thermal Expansion

If the cold water supply contains a backflowpreventer, check valve and / or a pressurereducing valve, the installer must install adomestic thermal expansion tank on the coldwater supply. (See Fig. 6 page 17)

Installing a thermal expansion tank willprevent normal thermal expansion fromrepeatedly forcing the T&P relief valveopen.

When installing a thermal expansion tankensure the charge pressure of the tank isequal to the cold water supply pressure atthe point of installation. Consult the ther-mal expansion tank manufacturer’s instruc-tions for further information on installationand sizing.

The Temperature / Pressure relief valveis not intended for constant duty, such asrelief of pressure due to normal thermalexpansion.

Water Hammer

Water hammer is the effect of sudden pres-sure changes occurring in the domestic pip-ing. These pressure changes are typicallythe result of “fast acting” positive shut-offvalves closing. These types of valves canbe typically found on dishwashers andclothes washers.

The effects of water hammering can causedamage to system components and tankwelds on the unit.

Installation of hammer arresters is recom-mended at these types of appliances, whichincorporate “fast-acting” positive shut-offvalves. Consult the manufacturer of waterhammer arresters for recommendation onsizing and installation requirements.

Temperature / Pressure Relief Valve

The PERFORMANCE PLUS has a factoryinstalled Temperature / Pressure Reliefvalve. Ensure the rating of the T&P reliefvalve is correctly sized as follows perAGA:

CAUTION

14

Model AGA RatingPG PLUS-25 100,000 Btu/hr

PG PLUS-30 200,000 Btu/hr




Domestic Piping

The installer must install discharge pipingonto the T&P relief valve. The dischargepiping must be:

• Made of material serviceable for tem-peratures of 250ºF or greater.

• Directed so that any hot water dis-charge flows away from all persons.

• Directed to a suitable place of drainage.

• Installed as to allow complete drainingof the T&P relief valve and the dis-charge piping.

• Terminated with a plain end, not withthreads.

Failure to properly direct the dischargepiping of the T&P relief valve may resultin flooding of the area adjacent to theunit and or lower floors in the structurecausing substantial property damage.

The installer must not install the T&Prelief valve discharge piping in a mannerthat is:

• Excessively long: Using more than 2elbows and/or 15 feet of discharge pip-ing can reduce the discharge capacity.

• Terminated directly into a drain: Thedischarge piping must terminate within6 inches of the drain. Check with localplumbing codes for termination guide-lines.

• The discharge piping is plugged, reducedin size or restricted in any manner.

• The discharge piping is subject to freez-ing.

DO NOT install any valves between theT&P relief valve and the discharge pip-ing. DO NOT plug the T&P relief valveor the discharge piping. Improper place-ment and piping of the T&P relief valvecan cause severe personal injury, deathor substantial property damage.

Thermostatic Mixing Valve

The PERFORMANCE PLUS contains a facto-ry installed thermostatic mixing valve withbuilt-in check valve.

The operating range of the thermostatic mixingis 90ºF to 120ºF.

For applications with a domestic recirculationloop, the recirculation pump should be con-trolled by an aquastat. The maximum recom-mended setting of the aquastat is 10ºF lowerthan the thermostatic mixing valve setting.

For proper operation of the thermostaticmixing valve and to prevent potentialscalding hazards, the recirculation loopshould be controlled by an aquastat. DONOT use continuous recirculation.

U-Tube Assembly

The PERFORMANCE PLUS is suppliedwith a U-Tube Assembly that directs coldwater to the thermostatic mixing valve.

To install the U-Tube Assembly theinstaller must:

1. Disconnect the cold inlet adapter/unionfrom the thermostatic mixing valve.

2. Using needle-nose pliers remove theplastic check valve assembly from theadapter.

15

Domestic Piping

3. Solder the U-Tube Assembly onto theadapter. (See Fig. 5)

4. Once the adapter has sufficientlycooled, re-insert the check valve assem-bly making sure of orientation andreconnect onto the mixing valve.

If the installation of the PERFORMANCEPLUS requires domestic hot water for acommercial dishwasher, the installer mayinsert a tee connection between the unit andthe mixing valve to provide 140ºF domes-tic hot water. The installer must referencelocal plumbing codes to ensure if this typeof application is permissible.

The thermostatic mixing valve MUST beinstalled and utilized on the PERFOR-MANCE PLUS. Removal of the thermo-static mixing valve will result in severepersonal injury or death.

The manual valve on the U-Tube assem-bly must remain in the full open positionfor proper operation of the thermostaticmixing valve.

Domestic Drain Valve

- The installer must install a drain valveand drain leg as shown in Fig. 6 page17 or Fig. 7 page 18.

- The drain valve should be positionedclose to the floor to aid in the siphonaction required to drain the inner tank.

Multiple Units Installation

For applications using multiple units thedomestic piping should be piped using a bal-anced manifold arrangement.

The installer should remove the thermostaticmixing valve from the units and install a singlethermostatic mixing valve at the outlet of thehot water manifold. The thermostatic mixingvalve should be sized according to the requiredflow rate and pressure drop. Refer to the ther-mostat mixing valve manufacturer specifica-tion and installation instructions for moredetails.

Reference Fig. 8, page 18 for piping diagram.

Storage Tank Application

For applications requiring large volumes ofdomestic hot water in a relative short period theinstaller may include a storage type tank (seeFig. 9 page 19) in the domestic piping. Theinstaller must:

1. Relocate the thermostatic mixing valvefrom the PERFORMANCE PLUS tothe outlet of the storage tank.

Primary Piping

SECTION V - Primary Piping

General Piping Requirements

Low Water Cutoff Device

- The PERFORMANCE PLUS is equippedwith a factory installed pressure switchstyle Low Water Cut Off device.

- The minimum operating system pressureallowable with this device is 10 psig.

- Check local codes which require a lowwater cutoff device for compliance ofthis device.

Backflow Preventer

- Use a backflow preventer valve in themake-up water supply to the unit asrequired by local codes.

Primary System Piping Applications

All piping applications shown in this instal-lation manual utilize a primary/ secondarypiping arrangement. This method is rec-ommended as a means to provide priorityto the production of domestic hot water.For other piping arrangements, consult theEngineering Department at Triangle Tubeor consult other approved/recognizeddesign arrangements.

On piping applications utilizing a singlezone or other recognized piping designarrangements it is recommended theinstaller uses flow/check valves withweighted seats at or near the appliance toprevent gravity circulation.

Expansion Tank and Makeup Water

Ensure the expansion tank is properly sizedfor the outer tank volume (20 gallons) andthe system volume and temperature.

Undersized expansion tanks will cause sys-tem water to be lost through the pressurerelief valve and cause additional makeupwater to be added to the system. Eventualprimary tank failure can result due to thisexcessive makeup water addition.

The expansion tank must be located asshown in Figure 11, 11A or 11B page 23 oras per recognized design methods. Refer tothe expansion tank manufacturer instruc-tions for additional installation details.

Connect the expansion tank to an air sepa-rator only if the air separator is located onthe suction side (inlet) of the system circu-lator. Always locate and install the systemfill connection at the same location as theexpansion tank connection to the system.

Diaphragm (Bladder) Expansion Tank

Always install an automatic air vent on thetop of the air separator to remove residualair from the system.

Closed-Type (Standard) Expansion Tank

It is recommended to pitch any horizontalpiping toward the expansion tank 1 inch per5 feet of piping. Use 3/4” piping for theexpansion tank to allow air within the sys-tem to rise.

For proper operation of the expansion tankand system, remove the factory installedautomatic air vent from the PERFOR-MANCE PLUS and plug the connection.(See Item 10, Fig. 46 page 68)

CAUTION

BEST PRACTICE

BEST PRACTICE

21

Primary Piping

DO NOT install automatic air vents on aclosed-type expansion tank system. Airmust remain in the system and bereturned to the expansion tank to pro-vide an air cushion. An automatic airvent would cause air to be vented fromthe system resulting in a water-loggedexpansion tank.

Circulator

The PERFORMANCE PLUS is suppliedwith a circulator that is pre-wired to allowfor domestic priority. Locate the circulatorin the return or supply piping as shown inthe piping diagrams included in this manual.

Closet (Zero Clearance) Applications

For applications in closets or zero clear-ances, the installer may use the upper prima-ry connection shown as Item 4 on page 70 asa primary return connection. The air elimi-nation, expansion tank and make-up watersystem should then be piped directly into theprimary loop of the space heating prior tothe system circulator.

Sizing Primary Piping

See Figure 12 through 15, pages 24 - 25,for recommended piping arrangementsbased on various applications. In all dia-grams, the space heating system is isolatedfrom the PERFORMANCE PLUS usingprimary / secondary piping connections.

Size the piping and system componentsrequired in the space heating system usingrecognized design methods.

System Piping - Zone Circulators

Connect the PERFORMANCE PLUS tothe system piping as shown in Fig. 12 page24 when zoning with zone circulators. Thecirculator supplied with the PERFOR-MANCE PLUS should not be used for aheat zone. It must supply only the prima-ry loop.

Install a separate circulator for each zone ofspace heating.

To control the zone circulators refer to Fig.34, page 45.

To ensure adequate flow rate throughthe PERFORMANCE PLUS, maintain aminimum 1 inch diameter on the systempiping connecting the unit to and fromthe primary / secondary connection.

System Piping - Zone Valves

Connect the PERFORMANCE PLUS to thesystem piping as shown in Fig. 13 page 24when zoning with zone valves. The prima-ry / secondary piping ensures the priority isgiven to the production of domestic hotwater.

To control the system circulator refer toFig. 33, page 44.


System Piping - Radiant Heating with MixingValve

Connect the PERFORMANCE PLUS to thesystem piping as shown with a radiant sys-tem using a thermostatic mixing valve asshown in Fig. 14 page 25. The primary / sec-ondary piping ensures sufficient return tem-perature to the PERFORMANCE PLUS.

NOTICE

NOTICE

CAUTION

22

Primary Piping

If the radiant system tubing contains nooxygen barrier, a stainless steel heatexchanger must be used. Failure toinstall a heat exchanger could lead topremature failure of the outer tank andvoid any warranty claim.

Venting and Combustion Air Installation

SECTION VI - Venting andCombustion Air Installation

General Requirements

- Installation must comply with localrequirements and with the NationalFuel Gas Code, NFPA 54/ ANSI Z223.1for U.S. installations and CSA B149.1or B149.2 for Canadian installations.

- The PERFORMANCE PLUS requiresa special vent system designed for pres-surized venting and is rated as ANSIZ21.13 Category IV (pressurized ventsystem, likely to condense within thevent system).

- The PERFORMANCE PLUS may bedirect vented with outside combustionair or non-direct vented using room air.

- The PERFORMANCE PLUS isapproved for the following vent manu-facturers:

• Heat Fab (Saf-T-Vent®)

• ProTech Systems (FasNSeal®)

• Flex-L (StaR-34)

• Z-Flex (Z-Vent III™)

DO NOT mix components from differentsystems. The vent system could fail orimproperly seal, causing leakage of flueproducts into the building.

Category IV Vent Termination - Guidelines

Locate the vent termination for direct or non-direct vent applications using the followingguidelines:

1. The total equivalent length of the ventshould not exceed 100 feet as given inTable 2, page 33.

2. The installer must consider the followingwhen determining the location of the venttermination:

- Locate the vent termination where fluevapors will not damage surroundingshrubs, plants or air conditioning equip-ment or be objectionable to the home-owner.

- The flue products will form a notice-able plume as they condense in colderair. Avoid terminating the vent in areaswhere the plume could obstruct win-dow views.

- Prevailing winds could cause freezingof flue condensation and a buildup ofwater / ice on surrounding plants, build-ing surfaces or combustion air inlet.

- Avoid locations of possible accidentalcontact of flue vapors with persons orpets.

- Avoid locations where prevailing windscould affect the performance of the unitor cause recirculation of the flue gases,such as inside corners of buildings ornear adjacent buildings or vertical sur-faces, window wells, stairwells,alcoves, courtyards, or other recessedareas.

- Do not terminate the vent above anydoors or windows; flue condensatecould freeze causing ice formations.

- Locate or guard the vent termination toprevent possible condensate damage toexterior finishes.

3. The vent termination and vent pipe mustnot extend more than 12 inches beyond theexterior wall.

4. Do not connect or terminate any otherappliance to the vent system or multipleunits into a common vent system.

WARNING

28


Category IV Vent Termination Clearances

Maintain the following clearances to the venttermination:

- At least 6 feet from adjacent walls

- No closer than 5 feet below roof over-hangs

- At least 7 feet above any public walk-ways

- At least 3 feet above any forced airintake (does not include the combustionair inlet) within 10 feet.

- The vent termination must be at least 4feet from any electric meters, gasmeter-regulators, relief valves or otherequipment. Never terminate the ventabove or below any of these items with-in 4 feet.

- Vent must terminate at least 12 inchesabove grade or common snow line.

In those applications in which the venttermination is below the projected snowline, the vent system can be routed verti-cally through an insulated chase or“riser box” and then terminated hori-zontally. The chase is to be constructedand insulated by the contractor, main-taining clearances for vertical and hori-zontal enclosures.

If the venting application is a horizontaldirect vent:

- Must maintain 12-inch clearancesbelow and horizontally from doors andwindows. See dimension A Fig. 17.

If the venting application is a horizontalnon-direct vent:

- Must maintain 4 feet of clearancebelow and horizontally from doors andwindows. See dimension A Fig. 17.

NOTICE

Fig.17: Termination of Vent system

Dimension ADirect Vent - 12 inchesNon-Direct Vent - 4 feet

29


If the venting application is a vertical director non-direct vent application:

- The vent must terminate at least 3 feetabove the roof and at least 2 feet higherthan any portion of the building within10 feet.

Multiple Vent Terminations

For multiple unit installation venting horizon-tally, it is recommended to vent as direct ventusing the Triangle Tube Thimble Box Kit. TheThimble Box terminations of the installationmust maintain the same horizontal centerline

and bespaced am i n i -mum 18i n c h e sf r o mcenter tocenter.

For multiple unit installation venting vertically,it is recommended to vent as direct vent usingTriangle Tube Vertical Vent Kit. The concen-tric vent / combustion air terminations mustmaintain a minimum 18 inch spacing from ventcenterline to vent centerline.

Locating the Combustion Air Inlet

When ducting outside combustion air directlyto the appliance the installer must use the fol-lowing guidelines:

1. The total equivalent length of the air inletduct should not exceed 100 feet as given inTable 2, page 33.

2. The installer must consider the followingwhen determining the location of the com-bustion air inlet:

- The air inlet must terminate at least 12inches above grade or projected snowline.

- The combustion air inlet must be locat-ed a minimum 12 inches from the venttermination. This does not apply on

direct vent applications using theThimble Box kit or the VerticalTermination Adapter of the VerticalVent kit.

- The combustion air inlet should not belocated above the vent terminationwhen direct venting.

- The combustion air inlet must be locat-ed in the same pressure zone as the venttermination.

Venting Option - Non Direct Vent / Vertical

In this vent application the PERFORMANCEPLUS is vented vertically through the roof oran unused chimney using 3 inch stainless ventmaterial and using room air for combustion.

The installer should consider the followingwhen choosing this vent option:

a. The vent system must contain a con-densate trap located no higher than 2feet above the unit. As shown in Fig. 19page 34.

b. The vent system must pitch back to theunit 1/4 inch per foot or as specified bythe vent manufacturer.

c. Clearance to combustibles must bemaintained per the vent manufacturer’srequirements. Refer to the vent manu-facturer’s installation instructions foradditional details.

d. At a minimum, a 3-inch elbow shouldbe placed on the combustion air inlet ofthe unit. This will prevent an acciden-tal blockage should anything be placedon top of the unit.

When using an unused chimney as ameans of a raceway for the 3 inch vent,the surrounding space cannot be used todraw combustion air.

Triangle Tube Thimble Box Kit

- Requires a 5 1/2 inch x 5 1/2 inch penetra-tion through any type of wall.

- Allows zero clearance at the wall penetration.

- Maximum wall thickness is 11 inches.

- The use of a termination elbow or horizon-tal tee termination for the venting system isnot recommended when using the ThimbleBox Kit.

To prevent potential nuisance lock-outsor flue gas recirculation it is recom-mended to terminate the vent with a hor-izontal termination tee or side dischargevent hood.

Excessive Horizontal Vent Runs

If maintaining the 1/4 inch per foot pitchrequirement creates clearance problems withstructural obstacles, i.e. low ceilings, theinstaller may opt to installing the vent in amanner that pitches up to a high point from theunit and then pitches away from the high pointto the vent termination.

A condensate tee should be installed as close aspossible to the unit when venting in this manner.

The vent run from the high point to the venttermination should be as minimal in length aspossible to reduce the amount of potential con-densate that may form in the vent system.

The vent system must maintain the 1/4 inch perfoot pitch to the high point and from the highpoint to the vent termination.

Vent Outlet Reducer

Prior to installing the appliance adapter or anyvent system components, the installer mustinstall the vent outlet reducer as shown in Fig.18, page 31.

Failure to install the vent outlet reducermay create improper vent connectionand potential flue gas leakage into thebuilding.

Position the combustion test port towardsthe front of the unit for ease of access.

Vent Appliance Adapters

- The PERFORMANCE requires the use ofan appliance adapter as approved by the oneof vent manufacturers listed on page 27.

Failure to use an approved vent appli-ance adapter may create improper ventconnection and potential flue gas leak-age. Do not mix the manufacturer appli-ance adapter with other manufacturers’vent components, the vent system couldfail or improperly seal, causing leakageof flue products into the building.

Vent Condensate Tee

A vent condensate tee and drain tube should beinstalled on a horizontal run of vent near theappliance to prevent any potential condensatefrom entering the flue ways on the unit. SeeFigures 19, 20, 21 and 22 page 34.

Failure to provide a vent condensate teeclose to the appliance could allow acidicflue gas condensate to enter into theappliance flue ways causing prematurefailure of the appliance.

Condensate Drain Tube

To prevent flue gases from entering into thebuilding it is important the drain tube is fash-ioned into a “pigtail” trap as shown in Figures19, 20, 21 and 22 page 34.

The drain tube must be filled with water to pre-vent flue gases from emitting into the buildingprior to operating the appliance.

Periodically inspect the water level in thecondensate drain tube. If low, add wateras needed to maintain trap level.

If water in drain tube evaporates rapidly due toambient conditions, propylene glycol may beadded or substituted to reduce evaporation.

Pipe the condensate drain tube to a suitableplace of drainage or to a condensate pump orsump. Consult local authorities regarding dis-posal of flue gas condensate into public wastewater system.

Determining Piping Lengths

Once the venting method and location for thevent termination has been determined theinstaller must select the vent componentsrequired for the system.

The maximum combined equivalent lengths forventing and combustion air inlet are as follows:

- Delta PERFORMANCE PLUS - 200feet (100 feet each)

The maximum equivalent length is thetotal length of the venting and the com-bustion air inlet combined. This includestermination fittings.

For Delta PERFORMANCE PLUSapplications that may exceed the 100 feetmaximum allowable equivalent lengthfor the venting system, contact TriangleTube Engineering Department for addi-tional information on how the appliancecan be adjusted to the application.

- For each elbow included in the system,the maximum allowable linear lengthmust be reduced as follows:

• Each 90º elbow within the system isthe equivalent of 10 linear feet.

• Each 45º elbow within the system isthe equivalent of 5 linear feet.

It is recommended that the installer uses thesame number of elbows and length of piping onthe venting system and the combustion airinlet.

Start-Up Preparations

SECTION X - Start Up PreparationCheck System and Domestic WaterChemistry

Do not use petroleum-base cleaning orsealing compounds in the primary sys-tem. Damage to seals and gaskets in thesystem components could occur, result-ing in substantial property damage.

System water including additives must bepractically non-toxic, having a toxicityrating or Class of 1, as listed in ClinicalToxicology of Commercial Products.

Water pH Level 6.0 to 8.0

Maintain the primary system water pHbetween 6.0 and 8.0. Check using litmuspaper or contact a water treatment compa-ny for a chemical analysis.

If the pH does not meet this requirement,do not operate the PERFORMANCEPLUS or leave the unit filled until the con-dition is corrected.

Water Hardness Less Than 7 Grains

For areas with unusually hard water (hard-ness above 7 grains) consult a water treat-ment company.

Chloride Concentration Less Than 80 mg/L

For those installations that use a water soft-ener or conditioner, consult the water treat-ment company.

Any water conditioning system mustbe installed and maintained in accor-dance with the water conditioner’smanufacturer’s specifications andwithin the operating guidelines of thePERFORMANCE PLUS.

Chlorinated Water

Do not use the PERFORMANCE PLUSinner or outer tank to heat a swimming poolor spa directly.

Maintain the chlorine level of the water inthe inner and outer tanks at levels consid-ered safe for drinking.

Flush Primary and Domestic System toRemove Sediment

The installer must flush both the primaryand domestic system to remove any sedi-ment to allow proper operation of the PER-FORMANCE PLUS.

Flush the systems until the water runs cleanand is free of sediment.

For primary zoned systems, each zoneshould be flushed through a purge valve.Purge valves and isolation valves should beinstalled on each zone to allow for properflushing of the system.

Check and Test Antifreeze

For primary systems containing antifreezesolutions, follow the antifreeze manufac-turer’s instructions in verifying theinhibitor level and to ensure the fluid char-acteristics are within specification require-ments.

Due to the degradation of inhibitors overtime, antifreeze fluids must be periodicallyreplaced. Refer to the manufacturer of theantifreeze for additional instructions.

- Ensure tank is partially filled withwater leaving an air gap as a cushion.Refer to the manufacturer’s instructionfor proper fill level.

- Ensure the tank is fitted with a devicethat reduces gravity circulation of air-saturated tank water back into the sys-tem. This device prevents air frombubbling up through the water as itreturns from the system.

- Ensure no automatic air vents are usedin the system. This will allow air toescape from the system instead ofreturning to the tank.

Diaphragm Tank:

- Ensure the system contains a minimumof one automatic air vent. Preferredlocation of the air vent should be atopan air eliminator.

- Remove the tank from the system andcheck the charge pressure. For residen-tial applications the charge pressure istypically 12 psig. If tank does not holda charge pressure, then the membrane isdamaged and the tank should bereplaced.

WARNING

Check Boiler Relief Valve

Inspect the relief valve and lift the lever toverify flow at least annually or as recom-mended on the warning tag of the valve.

Before manually operating the pressurerelief valve ensure the discharge piping isdirected to a suitable place of disposal toavoid a potential scald hazard. The dis-charge piping must be full size withoutrestriction and installed to permit com-plete drainage of both the valve and line.

If after closing the valve, the valve fails toseat properly or continually weeps, replacethe relief valve. Ensure the cause of therelief valve to weep is the valve itself, notdue to system over-pressurization causedby an expansion tank that is waterlogged orundersized.

Check Temperature / Pressure Relief Valve

Inspect the T&P relief valve and lift thelever to verify flow at least annually or asrecommended on the warning tag of thevalve.

Before manually operating the pressurerelief valve ensure the discharge piping isdirected to a suitable place of disposal toavoid a potential scald hazard. The dis-charge piping must be full size withoutrestriction and installed to permit com-plete drainage of both the valve and line.

If after closing the valve, the valve fails toseat properly or continually weeps, replacethe relief valve. Ensure the cause of theweeping is the valve itself, not due to ther-mal expansion or a faulty or under-pressur-ized thermal expansion tank.

Inspection of Ignition Electrode

Remove the ignition electrode from theburner mounting plate.

Remove any white oxides accumulated onthe electrode using fine grit sandpaper orsteel wool. If the electrode does not clean toa satisfactory condition, replace the ignitor.

When replacing the ignition electrode,ensure the gasket is in good condition andcorrectly positioned.

Check Ignition Wiring and Ground Wiring

Inspect the burner wiring from the burnercontrol module to the ground terminalbehind the control panel.

Ensure wiring is in good condition andsecurely connected.

Check ground continuity of the wiringusing a continuity meter.

Replace and correct ground wire if groundcontinuity is not completed and satisfactory.

Check Control Wiring

Inspect all control wiring located behindthe control panel and at the burner controlmodule. Ensure wiring is in good condi-tion and properly connected.

Check Thermostat Limit Settings

Check the position of the Secondary andPrimary Thermostat knobs, refer to Figure 38and 39 page 54 for recommended settings.

Perform Start-up and Checkout Procedures

Start the unit and perform the start-up pro-cedure as listed in this manual.

Verify the cold water fill pressure is correctand the operating pressure of the primarysystem is within normal operating range.

Complete the checkout procedures as refer-enced in this manual.

Re-assemble the venturi and gas valve ontothe blower. Ensure the venturi gasket is ingood condition and positioned correctly.

Re-assemble the burner head onto themounting plate. Ensure the burner headgasket is in good condition and positionedcorrectly.

Re-assemble the gas supply connection andopen the manual gas valve placing the unitback into service.

Flame Signal

The flame signal should be at least 0.6µ Α.Refer to the PERFORMANCE PLUSTrouble-shooting Guide for information onchecking the flame signal.

Check the ignitor for fouling or damagedinsulation if a low flame signal is read.

Check ground wiring and continuity as acause for low flame signal. Replace ignitorif conditions are satisfactory.

Check Combustion Levels

Refer to page 53 of this manual for mea-suring combustion levels and burneradjustments.
