2C-2. Outdoor Installation
Laars Lite 2 heaters can be installed in the low- profile, grate top configuration (U.S.A. only) as received from the factory, or with an optional high wind vent cap/stack. Canadian units require a factory approved vent cap.
feet (0.91 m) from vertical surfaces (e.g., nearby buildings and walls). The addition of a vent cap may be necessary.
2C-3. Flooring - Typical Installation
Do not install the heater directly on a combus- tible wood or carpet floor without placing a noncom- bustible platform between the floor and the heater. In the United States, the National Fuel Gas Code allows a heater to be placed on a combustible surface when there is a platform under the heater made of hollow masonry no less than 4 inches (102 millimeters [mm])
Figure 3. Outdoor Heater Installation.
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, glass openings, 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. In Canada this distance must be at least 10 feet (3.0 m) (see Figure 3).
WARNING
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. This prevents combustion gases from being diverted into living areas through doors, windows, or gravity inlets.
If the heater is installed close to a structure, protect it from rain water runoff with rain gutters on the roof or other measures. Do not locate the heater near sprinkler systems that could spray water on it.
Avoid locations where wind deflection off nearby structures might cause downdraft conditions. Where downdraft conditions exist, locate the heater at least 3
Notes:
1.Blocks must provide solid base and be braced so they cannot slip out of place.
2.Air openings in blocks must be arranged to provide unrestricted opening through entire width or length of base.

thick, covered with sheet metal at least 24 gauge thick and extending beyond the full width and depth of the heater by at least 6 inches (76.2 mm) in all directions. The masonry must be laid with ends unsealed, and joints matched to provide free circulation of air from side to side through the masonry (see Figure 4). If the heater is installed in a carpeted alcove, the entire floor of the alcove must be covered by a noncombustible panel. You can obtain a noncombustible base from Waterpik Laars, see the Parts List (Sec. 4) of this manual.
2C-4. Indoor and Outdoor Shelter Installations
All indoor installations and outdoor shelter installations (Canada) require the addition of a factory approved drafthood. The drafthood must be installed
