Tft Series Installation and Operation Instructions │Trinity73.0 BOILER LOCATIONIn all cases, the Trinity Tft must be installed indoors in a dry location where the ambient temperature must bemaintained above freezing and below 100F [38C]. All boiler components must be protected from dripping,spraying water, or rain during operation and servicing. Consider the proximity of system piping, gas andelectrical supply, condensate disposal drain, and proximity to vent termination when determining the best boilerlocation.Water or flood damaged components must be replaced immediately with new factory-approved components as failure to do so may result in fire, serious injury, or death.Boiler Area Ventilation Air OpeningsIf boiler area clearances are less than the recommended clearances specified in Table 3-1, the boiler area must beventilated (Exception: if the boiler area/room has a volume of 150 ft3 or greater, ventilation of the boiler room isnot required). Each ventilation air opening must meet the minimum requirements of 1 in2 per 1000 Btu/hr, butnot less then 100 in2. The lower ventilation opening must be located within 6” of the floor while the upperopening must be located 6” from the top of the space.If the "Boiler Area" does not meet the recommended clearances listed in Table 3-1, and ifthe boiler area has a volume less than 150 ft3, it is considered a Closet or Alcove. In US /Canada, PVC vent pipe and fittings shall not be used within the closet or alcove; onlyapproved CPVC, Polypropylene or Stainless Steel vent pipe and fittings can be used. See Table 4-4 for a list ofapproved materials. Under all circumstances, the minimum clearances listed in Table 3-1 must be provided.Closet InstallationsFor closet installations it is necessary to provide two ventilation air openings as shown in Figure 3-1, eachproviding a minimum area equal to 1 in2 per 1000 Btu/hr, but not less then 100 in2 and within 6” of the top andbottom of the closet door. See Table 3-1 for minimum clearances.Alcove InstallationsAlcove installations have the same minimum clearances as closet installations, except the front must becompletely open to the room at a distance no greater then 18” [457 mm] from the front of the boiler and theroom is at least three (3) times the size of the alcove. Provided these conditions are met, the boiler requires noextra ventilation air openings to the space. See Table 3-1for minimum clearances.Residential Garage InstallationsWhen installed in a residential garage, mount the boiler a minimum of 18” [457 mm] above the floor. Locate orprotect the boiler so it cannot be damaged by a moving vehicle. Check with your local authorities for otherpossible regulations pertaining to the installation of a boiler in a garage.Wall Mounting InstallationsThe Tft is provided with integrated wall mounting brackets. Refer to Figure 3-2 for instructions and illustrationson wall mounting.Table 3-1 Minimum Clearances for Installation and ServiceModel No. Clearances Dimensions - inches [mm]Front Top Sides Back Bottom Flue PipeTrinity Tft Minimum 24 [610] 1 12 [305] 4 [102] 0 9 [229] 1 [25]Recommended 36 [914] 24 [610] 12 [305] 0 24 [610] 1 [25]Notes:1 6” if surface is removable allowing a minimum of 24” [610 mm] clearance (i.e. closet installation).
