Trinity │Installation and Operation Instructions Ti Series
3.0 GENERAL VENTING
The Trinity Ti is a “Direct Vent” appliance requiring a “Special Venting System” designed for pressurized venting. Both the Vent and Air-Intake piping must be piped to the outdoors, using the vent material and rules outlined in this section. Under no conditions may this unit vent gases into a masonry chimney, unless it is vacant, and utilizes the approved venting material and rules described in this section. Installations must comply with the National Fuel Gas Code, ANSI Z223.1 (U.S.) or CSA B149.1 (Canada) and local requirements.
Vent and Air-Intake to be piped separately. The Trinity Ti cannot share a common vent or air-intake with multiple appliances. Failure to comply will result in serious injury or death.
Combustion Air-Intake Contamination
Be careful not to locate the Air-Intake termination in an area where contaminants can be drawn in and used for combustion. Combustion air containing dust, debris or air-borne contaminants will drastically increase the required maintenance and may cause a corrosive reaction in the Heat Exchanger which could result in premature failure, fire, serious injury, or death. See Table 3-1 for a list of areas to avoid when terminating air-intake piping:
Table 3-1 Corrosive Products and Contaminant Sources
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. Failure to follow instructions may result in serious injury or death.
Flammable Solvents and Plastic Piping
Due to the extremely flammable characteristics of most glues, cements, solvents and primers used in the process of joining plastic vent and air-inlet pipe, explosive solvent vapors must be evacuated from the vent and air-intake prior to start-up. Avoid using excess cement or primer that may lead to pooling inside the pipe assembly. Freshly assembled piping should be allowed to cure for a minimum of 8 hours before applying power to the gas fired appliance. Refer to Mandatory Pre-commissioning Procedure
for Plastic Venting in this section.
Flammable Cements and Primers – It is the installers’ responsibility to familiarize themselves with
the hazards associated with explosive solvents and to take all precautions to reduce these risks. Failure
to follow these instructions can cause explosions, property damage, injury or death.
Near Boiler Vent/Air-Intake Piping
Each Trinity Ti is equipped with a short piece of approved CPVC vent pipe. Insert one end into the boiler flue outlet adapter and cement the other to field venting (see Table 3-3 for approved venting material). The CPVC vent pipe should extend fully into the boiler flue outlet adapter (see Table 3-2). DO NOT insert PVC pipe directly into the flue outlet connection as it can deform from the clamping force of the gear clamp. Ensure that the venting system does not apply a load or strain on the boiler flue outlet adapter. The manufacturer recommends using two elbows to create a “swing joint” to reduce potential strain on vent piping and cemented joints. See Figure 3-1 for illustration.
Gasket Seating - Improper seating can cause leakage and eventual failure of the sealing gasket. Failure to follow these instructions may result in serious injury or death.

Vent/Air-Intake Pipe Material
Table 3-3 Acceptable Vent and Air-Intake Pipe Material
The use of cellular core PVC (ASTM F891), cellular core CPVC, or Radel® (polyphenolsulfone) in the exhaust venting system is prohibited. Failure to follow these
instructions may result in property damage, personal injury or death.
Covering non-metallic vent pipe and fittings with thermal insulation is prohibited. Failure to follow these instructions may result in property damage, personal injury or death.
Mandatory Pre-commissioning Procedure for Plastic Venting
1) Working with the power turned off to the boiler, completely install the vent and air intake system, securely cementing joints
together. If possible, allow primers/cements to cure for 8 hours before firing the burner. If curing time is less than 8 hours, proceed with Steps 2 through 6.
2) Maintain the boiler gas supply shut-off valve in the off position.
3) Disconnect electrical leads to the Hot Surface or Spark Igniter. Ensure the cables are placed in a fashion where they will not
arc to ground or other conductor.
4) Turn power on to the boiler and apply a heat demand.
5) Allow for 3 complete trials for ignition, consisting of pre and post purge of the combustion blower, until an ignition lockout
occurs. Repeat the process two more times (i.e. 9 complete ignition sequences in total).
6) Turn power off and reconnect the electrical leads to the Igniter.
Do not apply power to the boiler prior to Step 4 in the Mandatory Pre-commissioning Procedure for Plastic Venting.

Vent and Air-Intake Pipe Length Determination
Use Table 3-4 to determine the maximum pipe length that can be used. The table calculates sweep, 90º elbows, and 45º elbows at 5 equivalent feet [1.52 m] each. Note: models Ti150-200 have limitations when operating with Propane Gas (LP).
Example: A Ti200 can be installed with 105 equivalent feet [32 m] of air-intake piping and 105 equivalent feet [32 m] of vent piping when operating with Natural Gas. When operating with Propane Gas (LP), the maximum vent length in equivalent feet is
limited to 50’ (3” pipe).
The length of one vent pipe (intake or exhaust) may not exceed the length of the other vent pipe by more than 20 equivalent feet (6.1 m).
Table 3-4 Allowable Vent and Air-Intake Pipe Size and Lengths
Termination Options
The venting system of the Trinity Ti may be terminated using field supplied piping to construct a “Two-Pipe” termination, see Figures 3-3, 3-4a, 3-6, 3-9, 3-10 and 3-11. Alternatively, the venting may be terminated used a factory kit, either “Concentric” (see Figures 3-2, 3-4b, 3-5 and 3-7) or “Low Profile” (see Figure 3-8). The Concentric Vent Termination Kit can be either Roof or Sidewall terminated, while the Low Profile Termination Kit may only be Sidewall terminated. See Table 3-5 for details on the optional termination kits.
Venting Options - Due to potential moisture loading (build-up) along the exterior wall, sidewall venting may not be the preferred venting option. See Figs 3-2(b) and 3-3(b).
Optional Termination Kits Kits certified with the Trinity Ti are listed in Table 3-5 and available from IPEX and/or NTI. For more information on System 636

Venting Rules and Guidelines
1. Prevailing Winds: Ensure the vent is located where it will not be exposed to normal prevailing winds.
2. Combustion Air-Intake Contamination: Air for combustion must be drawn from outdoors from an area free of dust and
contaminants. Combustion air containing chemicals such as chloride, fluoride, bromine or iodine or dust and debris will cause corrosion damage of the heat exchanger voiding your NTI warranty. Refer to Table 3-1 for a list of corrosive products and contaminants sources to avoid.
3. Vertical Separation: The exhaust must be a minimum of 18” [457 mm] above the air inlet, and the air inlet must always be
a minimum of 12” [305 mm] plus snow allowance above any surface that will support snow. (Two feet plus snow allowance
is highly recommended). Consult your weather office, for the maximum typical snowfall for your region.
Example: New Brunswick Canada - typical maximum snowfall is 19”, thus the inlet must be (12”+19”) = 31” above grade
and exhaust must be (31”+18”) = 49” above grade.
4. Horizontal Separation: The horizontal distance between the inlet and exhaust must be a minimum of 4” [102 mm] center
to center. When the horizontal distance between the inlet and exhaust is greater than 12” [305 mm], the difference in horizontal distance must be determined and the vertical separation increased by the same amount.
Example: The horizontal distance (HD) = 24” [610 mm] and the vertical separation (VSmin) = 18” [457 mm], the new
vertical separation (VSnew) can be calculated using the following equation: VSnew = (HD - 12”) + VS, where VSnew = (24” - 12”) + 18” = 30”. (If the horizontal distance is greater than 6’ [1.83 m], no additional vertical spacing is required. Vertical separation is never
required to be greater than 36” [915 mm].
5. Wall Flashing: Under normal operating conditions this boiler will produce a plume of white gases, and should be taken into
consideration when selecting an adequate location. A 36” [915 mm] diameter stainless, plastic, or vinyl shield can be used to
flash the exterior of the residence.
6. Flue Gas Hazard: Position the vent termination where vapors cannot make accidental contact with people and pets or
damage nearby shrubs and plants.
7. Elbow Extensions: Elbows on outside of wall must be no more than ½” [13 mm] away from the wall.
8. Vent Sloping: All indoor exhaust piping must be on a slope back to the boiler a minimum of ¼” per linear foot of vent [6.25
mm per linear 305 mm]. For applications where excessive condensation is possible ½” per linear foot [13 mm per linear 305
mm] is recommended.
9. Vent Supports: Where required Vent and Air-intake piping shall be secured to the wall for more rigidity. All interior vent
pipe shall be supported a minimum of every 36” [915 mm].
10. Roof Exhaust: In all roof applications the discharge must point away from the pitch of the roof.
11. Roof Flashing: Install adequate flashing where the pipe enters the roof, to prevent water leakage.
12. Rain Cap: Install and seal a rain cap over existing chimney openings, in vacant chimney applications.
13. Venting Below Grade: For installations that exit the wall below grade refer to Figure 3-9.
14. Vent Screens: Install factory supplied vent screens on the outside of the last elbow for both the inlet and exhaust vent
terminal elbows. Install the screen into the female opening of the elbow. Then cut a small piece of pipe to sandwich the
screen into the elbow. NOTE be sure that the small piece of pipe cut, does not extend past the end of the elbow. Two
screens are provided in the package. See Figures 3-6 and 3-7. Vent screens are included in Optional Termination Kits.
15. Pipe Sizing: It is extremely important that the intake and exhaust vent piping be adapted to the appropriate size immediately
upon exiting the boiler cabinet. Refer to Figure 3-1 and Table 3-4.
16. Condensate Hazard: Do not locate vent over public walkways, driveways or parking lots. Condensate could drip and
freeze resulting in a slip hazard or damage to vehicles and machinery.
17. Warning Plate: Install the warning plate “Gas Vent Directly Below”, directly above (within 4 ft [1.22 m] vertically) the
location of the air inlet pipe, so it is visible from at least 8 ft [2.4 m] away. See Figures 3-5a and 3-6.
18. Wall Thickness: Direct vent terminations are designed to work with any standard wall thickness. Installation guidelines for
min/max wall thickness are as follows: Min.= 1” [25mm], Max.= 60” [1.52 m].
19. Venting Options: Due to potential moisture loading (build-up) along the exterior wall, sidewall venting may not be the
preferred venting option. Refer to Figures 3-2(b) and 3-3(b) for roof top venting options.

Figure 3-9
Venting Below Grade
For installations that exit the wall below grade:
1. Excavate site to a point below where the pipes are to
exit as shown.
2. Ensure that the wall is fully sealed where the pipes
penetrate the wall.
3. The Vent/Air-intake piping MUST be secured to the
side of the building above grade, as shown, to provide rigidity.
4. NTI Provides a mounting bracket PN. 82075 for
securing the exhaust pipes.
5. Ensure that the Vent/Air-Intake clearances are
maintained, see Section 4.0 for details.
Figure 3-10
Outdoor Horizontal Venting
Vent piping outside the Building is permitted under the following conditions:
1. The maximum length outside the building is 20 feet [6.1
m]. Note that outdoor length must be included in the overall vent length calculation.
2. All normal termination clearances are maintained.
3. The pipe is supported every 24” [610 mm].
4. The exhaust and inlet are sloped back to the boiler ½”
elevation for every linear foot [13 mm for every linear 305 mm].
Figure 3-11
Existing Chimney Chase Way
It is permissible to use an existing chimney as a chase way to run the Vent/Air-Intake piping as long as:
1. The chimney is not being used by any other boiler.
2. Flue gases don’t enter the vacant chimney.
3. Only Trinity certified venting materials are used, see
Section 3.0.
4. Vent lengths are within the maximums specified.
5. The top of the chimney is capped and the Vent/Air-Inlet
pipes are flashed to prevent leakage into the vacant chimney.

Notes:
1 - Canadian installations must comply with the current CSA B149.1 Natural Gas and Propane Installation Code and local
building codes. 2 - US installations must comply with current ANSI Z223.1/ NFPA 54 National Fuel Gas Code and local building codes. 3 - Horizontal separation center-to-center (c.c.) 4”-12” (102-305 mm). Refer to “Venting Rules and Guidelines” for
horizontal separation > 12” c.c. as it may impact vertical separation clearances. 4 - For US installations, an exhaust vent may be 3 ft above a mechanical air supply inlet if within 10 ft. [3 m] horizontally. 5 - Horizontal clearance must be observed up to a height of 15 ft. [4.6 m] above/below the meter, regulator, or relief devices. 6 - Concentric Vent must protrude from the roof precisely 24” [610 mm] measuring from the terminal end-cap vanes. 7 - Permitted if veranda, porch, deck, or balcony is made of concrete and a minimum of two sides are fully open beneath. 8 - 24” is the recommended snow level allowance above grade/roofline or any surface that will support snow, debris, or ice
(i.e. for roof venting clearances - roofline and snow level). If living in a snowfall region, consult your local weather
office for the maximum typical snowfall for your area. 9 - Note that the vent must maintain a minimum vertical distance above the air inlet. Example: Vent height = 18” (457
mm) above air inlet + 12” (305 mm) for air inlet above grade/roof line and snow level = 30” (762 mm) above grade and
snow level.
10 - Clearances to an outside corner to be in accordance with local installation codes. 11 - In Canada, concentric vent materials are subject to approval by local inspectors. See Termination Kits in Section 3.0.
12 - Above public walkways, driveways or parking lots if adjacent to it and condensate cannot drip, freeze, or create a hazard. 13 - Contact the manufacturer for special exemptions relating to multiple boiler installations using concentric vents.
