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
Figure 4. Non-Combustible Platform.
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.

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])
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
