Boiler Location - NTI Trinity Tft399 Installation And Operation Manual

Tft Series

3.0 BOILER LOCATION

In all cases, the Trinity Tft must be installed indoors in a dry location where the ambient temperature must be
maintained above freezing and below 100F [38C]. All boiler components must be protected from dripping,
spraying water, or rain during operation and servicing. Consider the proximity of system piping, gas and
electrical supply, condensate disposal drain, and proximity to vent termination when determining the best boiler
location.
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 Openings
Direct Vent – If boiler area clearances are less than the recommended clearances specified in Table 3-1, the
boiler area must be ventilated (Exception: if the boiler area/room has a volume of 150 ft
ventilation of the boiler room is not required). Each ventilation air opening must meet the minimum
2
requirements of 1 in
located within 6" of the floor while the upper opening 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 if
the boiler area has a volume less than 150 ft
vent pipe and fittings shall not be used within the closet or alcove; only approved CPVC,
Polypropylene or Stainless Steel vent pipe and fittings can be used. See Table 4-4 for a
list of approved materials. Under all circumstances, the minimum clearances listed in
Table 3-1 must be provided.
Indoor Combustion Air – When using Indoor Combustion Air in lieu of Direct Vent air-inlet piping, provisions
for combustion and ventilation air, in accordance with section "Air for Combustion and Ventilation," of the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 (U.S.), or Clause 8.2, 8.3 or 8.4 of Natural Gas and Propane
Installation Code, CAN/CSA B149.1 (Canada), or applicable provisions of the local building codes, must be
adhered to.
Closet Installations
For closet installations it is necessary to provide two ventilation air openings as shown in Figure 3-1, each
providing a minimum area equal to 1 in
bottom of the closet door. See Table 3-1 for minimum clearances.
Alcove Installations
Alcove installations have the same minimum clearances as closet installations, except the front must be
completely open to the room at a distance no greater then 18" [457 mm] from the front of the boiler and the
room is at least three (3) times the size of the alcove. Provided these conditions are met, the boiler requires no
extra ventilation air openings to the space. See Table 3-1for minimum clearances.
Residential Garage Installations
When installed in a residential garage, mount the boiler a minimum of 18" [457 mm] above the floor. Locate or
protect the boiler so it cannot be damaged by a moving vehicle. Check with your local authorities for other
possible regulations pertaining to the installation of a boiler in a garage.
Wall Mounting Installations
The Tft is provided with integrated wall mounting brackets. Refer to Figure 3-2 for instructions and illustrations
on wall mounting.
