Trinity Lx │Installation and Operation Instructions Lx Series83.0 APPLIANCE LOCATIONIn all cases, the Trinity Lx must be installed indoors in a dry location where the ambient temperature must bemaintained above freezing and below 100°F [38°C]. Gas components must be protected from dripping, sprayingwater, 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 appliance 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 MountingThe Trinity Lx can be mounted directly on combustible flooring, with the exception of carpeting. Installing theappliance on carpeting is not permissible. Ensure the appliance is mounted above any anticipated flood level.Models Lx150-400 come equipped with stationary, low profile legs. Lx500-800 models include factorysupplied/field installed leveling legs. Once the unit is removed from the pallet, thread the leveling legs into theallocated threaded inserts in the bottom of the unit.Appliance Area Ventilation Air OpeningsIf appliance area clearances are less then the recommended clearances specified in Table 3-1, the appliance areamust be ventilated. Each ventilation air opening must meet the minimum requirements of 1 in2 per 1000 Btu/hr,but not 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. The Lx500-800 has an optional Indoor Combustion AirKit that can be installed in lieu of direct vent air intake piping. Note that the Indoor Combustion Air option is notto be used in conjunction with closet or alcove installations. See "Mechanical Room Installations" below.If the "Appliance Area" does not meet all of the recommended clearances listed in Table3-1, it is considered a Closet or Alcove. The use of PVC venting (exhaust and air-intake)is not permitted within the Closet or Alcove. See Table 4-3 for a list of approved materials.Closet InstallationsFor 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 in2 per 1000 Btu/hr, but not less then 100 in2 and within 6” of thetop and bottom of the closet door. See Table 3-1for minimum recommended 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 appliance and theroom is at least three (3) times the size of the alcove. Provided these conditions are met, the appliance requiresno extra ventilation air openings to the space. See Table 3-1for minimum recommended clearances.Residential Garage InstallationsWhen installed in a residential garage, mount the appliance a minimum of 18” [457 mm] above the floor. Locateor protect the appliance so it cannot be damaged by a moving vehicle. Check with your local authorities forother possible regulations pertaining to the installation of an appliance in a garage.Mechanical Room Installations (Commercial)The Trinity Lx500-800 is certified for use as a Direct Vent System, where flue gas and combustion air piping areconnected directly to the appliance. In addition, it is the only Lx model certified for use with an IndoorCombustion Air System where flue gas piping is connected directly to the appliance, but combustion air isdrawn directly from the room. Room supplied combustion air systems are subject to additional codesrequirements such as pre-ignition interlocks with motorized dampers or auxiliary proving circuits whenoperating in rooms with mechanical exhaust fans. See Table 4-1 for combustion air contamination sources toavoid, Table 4-5 for a list of design considerations and installation guidelines, and Figure 4-13 for Kit details.Wall Mounting Installations (Optional)Lx150-400 models are shipped with wall mounting brackets to provide installers with the option of wallmounting the appliance. The Lx500-800 are not available as a wall mountable unit. Refer to Figures 3-3(a) and3-3(b) for instructions and illustrations on wall mounting applicable models. Note that Water Heaters require"Mandatory Wall Mounting Protection". Refer to Section 1.0 in Appendix C, "Water Heater Applications:Plumbing & Wiring Instructions" for further details.
