4.0 GENERAL VENTING
The Trinity Ts is a “Direct Vent” boiler 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 Ts cannot share a common vent or
air-intake with multiple boilers.
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 4-1 for a list of areas to avoid when terminating air-intake piping:
Table 4-1 Corrosive Products and Contaminant Sources
Products to Avoid
Contaminated Sources to Avoid
Antistatic fabric softeners, bleaches, detergents, cleaners
Laundry facilities
Perchloroethylene (PCE), hydrocarbon based cleaners
Dry cleaning facilities
Chemical fertilizer, herbicides/pesticides, dust, methane gas
Farms or areas with livestock and manure
Paint or varnish removers, cements or glues, sawdust
Wood working or furniture refinishing shops
Water chlorination chemicals (chloride, fluoride)
Swimming pools, hot tubs
Solvents, cutting oils, fiberglass, cleaning solvents
Auto body or metal working shops
Refrigerant charge with CFC or HCFC
Refrigerant repair shops
Permanent wave solutions
Beauty shops
Fixer, hydrochloric acid (muriatic acid), bromide, iodine
Photo labs, chemical / plastics processing plants
Cement powder, crack fill dust, cellulose, fiber based insulation
Concrete plant or construction site
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this
or any other boiler. 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 assembly should be allowed to cure for a minimum of 8 hours before applying power to the gas
fired boiler. 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 Ts 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 4-3 for approved venting material). The CPVC
vent pipe should extend fully into the boiler flue outlet adapter (see Table 4-2).
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 Figures 4-1 through 4-3 for illustrations.
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.
