If the PERFORMANCE combustion airinlet is located in any area likely to causeor contain contamination, or if products,which would contaminate the air cannotbe removed, the combustion air must berepiped and terminated to an outsidelocation. Contaminated combustion airwill damage the unit and its burner sys-tem, resulting in possible severe personalinjury, death or substantial propertydamage.

Do not operate a PERFORMANCE if itscombustion air inlet is taken inside in alaundry room or pool facility. Theseareas will always contain hazardous con-taminants.

Pool chemicals, laundry products, com-mon household cleaners and hobbyproducts often contain fluorine or chlo-rine compounds. When these chemicalspass through the burner and vent sys-tem, they can form strong acids. Theseacids can create corrosion of the outertank, burner components and vent sys-tem, causing serious damage and pre-senting a possible threat of flue gasspillage or water leakage into the sur-rounding area.

Please read the information listed below.If contaminating chemicals are locatednear the location of the combustion airinlet, the installer should pipe the com-bustion air inlet to an outside area perSECTION VI of this installation manual.

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 from the systempiping.

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 to the domesticinner tank contains a backflow preventer,check valve and / or a pressure reducingvalve, the installer must install a domesticthermal expansion tank on the cold watersupply. (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 has a factoryinstalled Temperature / Pressure Reliefvalve. Ensure the rating of the T&P reliefvalve is correctly sized as follows perAGA:

CAUTION

Model AGA RatingPG-25 100,000 Btu/hr

PG-30 200,000 Btu/hr

PG-35 200,000 Btu/hr

PG-40 200,000 Btu/hr

PG-45 200,000 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 contains a factoryinstalled thermostatic mixing valve with built-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 is supplied with aU-Tube Assembly that directs cold water tothe thermostatic mixing valve.

To install the U-Tube Assembly theinstaller must:

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

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

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 PERFORMANCErequires domestic hot water for a commer-cial dishwasher, the installer may insert atee connection between the unit and themixing valve to provide 140ºF domestichot 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. Removal of the thermostaticmixing valve will result in severe person-al 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 page 17or 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,the installer may include a storage type tank(see Fig. 9 page 19) in the domestic piping.The installer must:

1. Relocate the thermostatic mixing valvefrom the PERFORMANCE to the out-let of the storage tank.

2. Provide recirculation from the storagetank back to the PERFORMANCEusing a bronze type circulator.Maximum recommended flow rate is 5to 10 gpm.

This can be accomplished through thedrain connection if a 3rd tapping isunavailable and the circulator should becontrolled by an aquastat.

General Piping Requirements

Low Water Cutoff Device

- The PERFORMANCE is equipped with afactory installed pressure switch styleLow 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.

To prevent potential outer tank failure,the primary system piping must be a“closed” loop sytem to avoid any oxygencontamination of the boiler water.

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.

21

Primary Piping

For proper operation of the expansion tankand system, remove the factory installedautomatic air vent from the PERFOR-MANCE and plug the connection. (SeeItem 10, Fig. 46 page 70)

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 is supplied with acirculator that is pre-wired to allow fordomestic priority. Locate the circulator inthe return or supply piping as shown in thepiping 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 Figs: 12 through 15, pages 24 - 25, forrecommended piping arrangements basedon various applications. In all diagrams,the space heating system is isolated fromthe PERFORMANCE using primary / sec-ondary piping connections.

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

System Piping - Zone Circulators

Connect the PERFORMANCE to the sys-tem piping as shown in Fig. 12 page 24when zoning with zone circulators. Thecirculator supplied with the PERFOR-MANCE should not be used for a heatzone. It must supply only the primary loop.

Install a separate circulator for each zone ofspace heating.

To control the zone circulators refer to Fig.34, page 47.

To ensure adequate flow rate throughthe PERFORMANCE, maintain a mini-mum 1 inch diameter on the system pip-ing connecting the unit to and from theprimary / secondary connection.

System Piping - Zone Valves

Connect the PERFORMANCE to the sys-tem 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 46.

Venting and Combustion Air Installation

SECTION VI - Venting and CombustionAir Installation

General Requirements - Category I

The venting system must be installed in accor-dance with:

- NFPA 54 National Fuel Gas Code, ANSIZ223.1.

- NFPA 211 Standard for Chimneys, Ventand Solid Fuel Burning Appliances.

For installations in Canada the venting systemmust be installed in accordance with:

- CGA / B149 Installation Code for GasBurning Equipment.

- Prior to installing the appliance into anexisting chimney or venting system, thevent system should be inspected forcondition and obstructions.

If the inspection reveals the vent systemis not safe for the intended use, it shall berepaired, rebuilt, lined, relined orreplaced with a vent or chimney to con-form to NFPA 211, latest edition. Failureto conduct such an inspection and/orrepair could result in severe personalinjury, death or substantial propertydamage.

- No portion of the venting system shallextend into or pass through any circu-lating air duct or furnace plenum.

- The gas venting system shall beinstalled, in accordance with their list-ings and the manufacturer’s instruc-tions.

Masonry and Metal Chimneys

- The NFPA code book severely limits theinstallation of the PERFORMANCE intoa masonry chimney. For applicationsusing either interior or exterior masonrychimney a listed, approved metal chim-ney lining system should be used.

For any applications using an exteriorchimney it is recommended that an insu-lated or stainless steel chimney liningsystem be used.

A chimney with one or more sidesexposed to the outside of the structure isconsidered to be an exterior chimney.

- The chimney shall extend at least 5 feetabove the highest connected applianceflue collar.

- The chimney shall extend at least 3 feetabove the highest point where it passesthrough a roof of a building and at least2 feet higher than any portion of abuilding within a horizontal distance of10 feet.

Type B Vent Systems

- The vent system should terminate inaccordance with NFPA 54, latest edi-tion, provided the termination is at least8 feet from a vertical wall or similarobstruction.

The Type B vent system shall extend in ageneral vertical direction with offsets notexceeding 45 degrees. A vent systemhaving not more than one 60 degree off-set shall be permitted. Any angle greaterthan 45 degrees is considered horizontal.

BEST PRACTICE

NOTICE

BEST PRACTICE

WARNING

28


The total horizontal distance of a ventplus the horizontal vent connector shallnot be greater than 75% of the verticalheight of the vent.

Vent Connectors

- When a vent connector must be locatedin or pass through an un-conditionedspace, attic or crawl space, that portionof the vent connector must be listed asType B or other approved material hav-ing equivalent insulation qualities.

- The minimum clearance to com-bustibles for single wall vent connec-tors shall be 6 inches.

- The minimum clearance to com-bustibles for Type B vent connectorsshall be 1 inch or per vent manufactur-er’s instructions.

- The vent connector shall be installed ina manner to avoid excessive turns orother construction features that createexcessive resistance to the flow of thevent gases.

- The vent connector should be installedin a manner without any dips or sagsand should slope upward toward thevent or chimney at least 1/4 inch per 1foot.

- The location of the appliance should belocated as close to the vent or chimneyto maintain the vent connector length asshort as possible.

The maximum horizontal length allow-able should not exceed 75% of the heightof the vent or chimney assuming no off-sets in the vertical vent.

- The entire length of a vent connectorshall be readily accessible for inspec-tion, cleaning and replacement.

- The diameter of the vent connectorshould not be upsized more than twosizes greater than the flue outlet diameter.

The minimum recommended vent con-nector given in Table 1 is only a generalguideline. The vent system must bedesigned and installed in compliancewith all applicable codes. Failure toproperly size and install the vent systemcould result in severe personal injury,death or substantial property damage.

There are certain applications for thePERFORMANCE in which upsizing thevent connector to 5 inches will not resultin sufficient maximum capacity require-ments. In these applications theinstaller, after consultation with TriangleTube Engineering, may upsize the ventconnector to 6 inches provided the ventconnector and vent system are Type B.

Common Venting - Category I

The PERFORMANCE may be vented into acommon vent system using the guidelines andsizing Tables of the National Fuel Gas CodeNFPA 54 ANSI Z223.1 latest edition.

The PERFORMANCE may also be vented intoa common multi story vent using the guidelinesand sizing Tables of the National Fuel GasCode NFPA 54 ANSI Z223.1 latest edition.

General Requirements - Category III

- 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 requires a spe-cial vent system designed for pressur-ized venting and is rated as ANSIZ21.13 Category III (pressurized ventsystem, with flue temperature thatavoids excessive condensate within thevent system).

- The PERFORMANCE may be directvented with outside combustion air ornon-direct vented using room air.

- The PERFORMANCE is approved forthe following vent manufacturers:

• 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 III 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 35.

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. The vent termination for thehorizontal concentric snorkel kit must notextend more than 24” beyond the exteriorwall.

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

Category III Termination Clearances

Maintain the following clearances to the venttermination:

- At least 6 feet from adjacent walls

WARNING

30


- 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 installer has 2 options. In thefirst option, the vent system can be rout-ed vertically through an insulated chaseor “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. In the second optionthe installer can use the horizontal con-centric snorkel kit see Fig. 22B page 36.

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.

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.

NOTICE

Multiple Vent Terminations

For multiple unit installation venting horizon-tally, it is recommended to vent as direct ventusing the Horizontal Wall Thimble Kit orHorizontal Concentric Kit. The terminationson these installations must maintain the samehorizontal centerline and be spaced a minimum18 inches from center to center.

For multiple unit installation venting vertically,it is recommended to vent as direct vent usingTriangle Tube Vertical Concentric Vent Kit.The concentric vent / combustion air termina-tions must maintain a minimum 18 inch spac-ing from vent centerline to vent centerline.

Locating the Combustion Air Inlet

When ducting outside combustion air directlyto the unit when venting as a Category I orCategory III appliance the installer must usethe following guidelines:

1. The total equivalent length of the air inletduct should not exceed 100 feet as given inTable 2, page 35.

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 locateda minimum 12 inches from the vent ter-mination when installing separate airand vent pipes through a side wall. Thisdoes not apply to horizontal concentric-direct venting applications using theHorizontal Wall Thimble kit. See Fig.23, page 37.

- The combustion air inlet should not belocated above the vent termination.

- The combustion air inlet must be locat-ed in the same pressure zone as the venttermination. This does not apply whenventing the appliance as Category I.

Venting Option - Non Direct Vent / Vertical

In this vent application the PERFORMANCEis vented vertically through the roof or anunused chimney using only approved 3 inchstainless steel vent material and using room airfor 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 35.

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 withscreen should be placed on the combus-tion air inlet of the unit. This will pre-vent an accidental blockage shouldanything be placed on 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.

Venting Option - Direct Vent / Vertical

In this vent application the PERFORMANCEis vented vertically through the roof or anunused chimney using the Triangle Tube con-centric Vertical Vent Kit.

NOTICE

a. The vent system should contain a conden-sate trap located near the unit as shown inFig. 20, page 35.

b. The vent system must pitch back to the unit1/4 inch per foot as a minimum.

c. The vent system must maintain the follow-ing clearances to combustibles:

- 0 inches when there are no horizontaloffsets and fully enclosed by com-bustibles on all sides

- 1 inch when there are horizontal offsetsand fully enclosed by combustibles onall sides.

- 0 inches with or without offsets andunenclosed or with 1 side open and amaximum 3 sides enclosed with com-bustible materials.

- 0 inches with or without offsets andenclosed with non combustible materials.

Venting Option - Non-Direct Vent /Horizontal

In this vent application the PERFORMANCEis vented horizontally through a wall usingonly approved 3-inch stainless steel vent mate-rial and using room air for combustion.


a. The vent system must contain a con-densate trap located near the unit asshown in Fig. 21 page 36.

b. The vent system must be pitched a min-imum 1/4 inch per foot or as specifiedby the vent manufacturer.

Although the vent system is allowed topitch away from the unit, it is recom-mended that the vent system pitchestoward the unit with a condensate draininstalled as close to the unit as possible.Opting to pitch the vent system awayposes potential damage to the buildingexterior or to the surrounding landscapeand/or potential risks of icing if conden-sate is formed.

c. Penetration at the wall requires a wallthimble.

d. Clearance to combustibles must bemaintained per the vent manufacturer’srequirements. Reference the vent man-ufacturer’s installation instructions foradditional details.

Maintain a minimum 2-inch clearance tocombustible wall and 1-inch clearance tonon-combustible in the absence of thevent manufacturer’s recommendedclearance when penetrating a sidewall.

e. At a minimum a 3-inch elbow withscreen should be placed on the combus-tion air inlet of the unit. This will pre-vent an accidental blockage shouldanything be placed on top of the unit.

Venting Option - Direct Vent /Horizontal

In this vent application the PERFORMANCEtypically is vented horizontally through a wallusing only approved 3-inch stainless steel ventmaterial and using outside air for combustion.


a. The vent system should contain a con-densate trap located near the unit asshown in Figs. 22, 22A & 22B, page 36.

b. The vent system must pitch back to theunit 1/4 inch per foot.

c. Penetration at the wall requires athimble.

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

Maintain a minimum 2-inch clearance tocombustible wall and 1-inch clearance tonon-combustible in the absence of thevent manufacturer’s recommendedclearance when penetrating a sidewall.

e. For a zero clearance concentric termi-nation of the vent and combustion airrefer to the Horizontal Concentric,Horizontal Single Wall Vent orHorizontal Wall Thimble Kits.

There are two methods available for DirectVenting - Horizontal:

Separate: The vent and the combustion airinlet are run together and exit the structure sep-arately with different terminations. See Fig. 23,page 37.

The combustion air inlet and the venttermination must reside in the samepressure zone area of the building forproper operation of the appliance.

Combination: The vent and combustion air ter-minate at a single concentric point using theHorizontal Concentric, Horizontal Single WallVent or Horizontal Wall Thimble Kit. See Figs.:22,22A and 22B, page 36.

Horizontal Wall Thimble 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 for theventing system is not recommended whenusing the Horizontal Wall Thimble Kit.

To prevent potential nuisance lock-outsor flue gas recirculation it is recommend-ed to terminate the vent with a horizon-tal termination tee or side discharge venthood.

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 a man-ner that pitches up to a high point from the unitand then pitches away from the high point tothe vent termination.

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

BEST PRACTICES

NOTICE

NOTICE

BEST PRACTICE

34


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 at the vent termination.

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

Vent Appliance Adapters

- The PERFORMANCE requires the use ofan appliance adapter as approved by the oneof vent manufacturers listed on page 29.

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 Drain

A vent condensate drain and drain tube shouldbe installed near the appliance to prevent anypotential condensate from entering the flueways on the unit. See Figs. 19 through 22Bpages 35 & 36.

Failure to provide a vent condensatedrain close to the appliance could allowacidic flue gas condensate to enter intothe appliance flue ways causing prema-ture failure 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 Figs. 19through 22B pages 35 & 36.

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 - 200 feet (100feet each)

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