Water Heater Location - NY Thermal Trinity Lx-WH Series Installation And Operation Manual

Lx – WH Series

3.0 WATER HEATER LOCATION

In all cases, the Trinity Lx must be installed indoors in a dry location where the ambient temperature must be
maintained above freezing and below 100F [38C]. Gas 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 water heater 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.
Floor Mounting
The Trinity Lx can be mounted directly on combustible flooring, with the exception of carpeting. Installing the
water heater on carpeting is not permissible. Ensure the water heater is mounted above any anticipated flood
level. Models Lx200WH-Lx400WH come equipped with stationary, low profile legs. Models Lx500WH-
Lx800WH include factory supplied/field installed leveling legs. Once the unit is removed from the pallet, thread
the leveling legs into the allocated threaded inserts in the bottom of the unit.
Water heater Area Ventilation Air Openings
Direct Vent – If water heater area clearances are less than the recommended clearances specified in Table 3-1,
the water heater area must be ventilated. (Exception: if the water heater area/room has a volume of 150 ft
greater, ventilation of the water heater room is not required). Each ventilation air opening must meet the
minimum requirements of 1 in
must be located within 6" of the floor while the upper opening must be located 6" from the top of the space.
If the "Water heater Area" does not meet the recommended clearances listed in Table 3-
1, and if the water heater area has a volume less than 150 ft
Alcove. PVC 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 4-3 for a list of approved materials.
Indoor Combustion Air – When using Indoor Combustion Air in lieu of Direct Vent air-inlet piping (an option
for models Lx500WH-Lx800WH), 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(a), (b) and
(c), each providing a minimum area equal to 1 in
top and bottom of the closet door. See Table 3-1for minimum recommended 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 than 18" [457 mm] from the front of the water heater and
the room is at least three (3) times the size of the alcove. Provided these conditions are met, the water heater
requires no extra ventilation air openings to the space. See Table 3-1for minimum recommended clearances.
Residential Garage Installations
When installed in a residential garage, mount the water heater a minimum of 18" [457 mm] above the floor.
Locate or protect the water heater so it cannot be damaged by a moving vehicle. Check with your local
authorities for other possible regulations pertaining to the installation of a water heater in a garage.
Wall Mounting Installations (Optional)
Lx200WH-Lx400WH models are shipped with wall mounting brackets to provide installers with the option of
wall mounting the water heater. Lx500WH-Lx800WH models are not available as a wall mountable unit. Refer
to Figures 3-3(a) and 3-3(b) for instructions and illustrations on wall mounting applicable models.
