2D. Outdoor Installation
The LX and LT heaters can be installed in the outdoor configuration as received from the factory.
Locate the heater in an open, unroofed area. Do not install the heater under a deck. Do not locate the heater below or adjacent to any doors, windows, louvers, grills, etc., which connect in any way with an inhabited area of a building, even though the access might be through another structure (e.g., a garage or utility room. In the United States there must be a minimum of 4 feet (1.22 m) horizontally or vertically between the heater and any door, glass opening, or gravity inlet to a building (see Figure 2).
DANGER
United States
Do not install the heater with the top of the vent assembly within 4 feet (1.22 m) of any opening into a building.
Canada
Do not install the heater with the top of the vent assembly within 10 feet (3.05 m) of any opening into a building.
If the heater is installed under an overhang, there must be a minimum clearance of 5 feet (1.5 m) above the top of the heater and the structure should not overhang the heater more than 12 inches (0.30 m). The area under the overhang must be open on three sides.
If the heater is installed close to a structure, protect it

from rain water runoff by means of gutters, roof water diverters or similar measures. Do not locate the heater close to irrigation sprinklers. Water from sprinklers may damage controls and electronic components.
Avoid locations where wind deflection off nearby structures might cause wind loading and downdraft conditions. Where downdraft conditions exist, locate the heater at least 3 feet (0.91 m) from vertical surfaces (e.g., nearby buildings and walls).
Install the heater at least 5 feet (1.52 meters) from the inside wall of the pool or spa unless the heater is separated from the pool or spa by a
2E. Outdoor Shelter Installation (Canada)
An outdoor shelter is an unoccupied enclosure which does not communicate directly with occupied areas. The LX and LT may be installed in such a shelter only when the installation is in accordance with local codes and the most recent edition of Standard CAN/CGA
2F. Indoor Installation
If the LX or LT is to be installed indoors, its exhaust discharge grill must be converted to a collar for vent pipe connection. The necessary vent collar, gasket and screws can be ordered as parts kit R0331403 or R0331405 (see parts list in Section 5 of this manual). The conversion can be done quite simply as follows:
1.Remove the vent exhaust grill by removing the four screws which retain it. The grill and the screws may be discarded (See Figure 3).
2.Replace the grill with the vent collar (see section 4 for kit number). Place the vent collar and gasket over the hole and fasten it in place with the 4 screws provided. Be sure that all components are properly aligned (See Figure 4).
3.Install the vent pipe on the indoor vent collar. The collar will accommodate vent piping of nominal 7" or 9" diameter, depending upon the model of your heater (See Figure 5). See vent installation section for important information on selecting proper pipe size.
