Trinity │Installation and Operation Instructions Ti Series63.0 GENERAL VENTINGThe Trinity Ti is a “Direct Vent” appliance requiring a “Special Venting System” designed for pressurized venting. Both theVent and Air-Intake piping must be piped to the outdoors, using the vent material and rules outlined in this section. Under noconditions may this unit vent gases into a masonry chimney, unless it is vacant, and utilizes the approved venting material andrules 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-intakewith multiple appliances. Failure to comply will result in serious injury or death.Combustion Air-Intake ContaminationBe 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 maycause a corrosive reaction in the Heat Exchanger which could result in premature failure, fire, serious injury, or death. See Table3-1 for a list of areas to avoid when terminating air-intake piping:Table 3-1 Corrosive Products and Contaminant SourcesProducts to Avoid Contaminated Sources to AvoidAntistatic fabric softeners, bleaches, detergents, cleaners Laundry facilitiesPerchloroethylene (PCE), hydrocarbon based cleaners Dry cleaning facilitiesChemical fertilizer, herbicides/pesticides, dust, methane gas Farms or areas with livestock and manurePaint or varnish removers, cements or glues, sawdust Wood working or furniture refinishing shopsWater chlorination chemicals (chloride, fluoride) Swimming pools, hot tubsSolvents, cutting oils, fiberglass, cleaning solvents Auto body or metal working shopsRefrigerant charge with CFC or HCFC Refrigerant repair shopsPermanent wave solutions Beauty shopsFixer, hydrochloric acid (muriatic acid), bromide, iodine Photo labs, chemical / plastics processing plantsCalcium Chloride De-Icing / Ice MeltersCement powder, crack fill dust, cellulose, fiber based insulation Concrete plant or construction siteDo not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any otherappliance. Failure to follow instructions may result in serious injury or death.Flammable Solvents and Plastic PipingDue to the extremely flammable characteristics of most glues, cements, solvents and primers used in the process of joining plasticvent and air-inlet pipe, explosive solvent vapors must be evacuated from the vent and air-intake prior to start-up. Avoid usingexcess cement or primer that may lead to pooling inside the pipe assembly. Freshly assembled piping should be allowed to curefor a minimum of 8 hours before applying power to the gas fired appliance. Refer to Mandatory Pre-commissioning Procedurefor Plastic Venting in this section.Flammable Cements and Primers – It is the installers’ responsibility to familiarize themselves withthe hazards associated with explosive solvents and to take all precautions to reduce these risks. Failureto follow these instructions can cause explosions, property damage, injury or death.Near Boiler Vent/Air-Intake PipingEach Trinity Ti is equipped with a short piece of approved CPVC vent pipe. Insert one end into the boiler flue outlet adapter andcement the other to field venting (see Table 3-3 for approved venting material). The CPVC vent pipe should extend fully into theboiler flue outlet adapter (see Table 3-2). DO NOT insert PVC pipe directly into the flue outlet connection as it can deform fromthe clamping force of the gear clamp. Ensure that the venting system does not apply a load or strain on the boiler flue outletadapter. The manufacturer recommends using two elbows to create a “swing joint” to reduce potential strain on vent piping andcemented joints. See Figure 3-1 for illustration.Gasket Seating - Improper seating can cause leakage and eventual failure of the sealing gasket. Failureto follow these instructions may result in serious injury or death.
