The installation of a spark arrester is recommended,
particularly where there are dry conditions or where
there is combustible material near the unit, unless the
installation of a spark arrester is prohibited by local
requirements. Use common sense to avoid potential
fires, including exercising caution when disposing
of ashes, cleaning and refueling. Keep all highly
combustible materials (e.g., gasoline, propane, leaves,
pine needles, etc.) away from an operating unit at all
times. Take special precautions in windy conditions.

GENERAL INSTALLATION INFORMATION

Foundation

The outdoor furnace may be installed directly on stable,
level ground without the necessity of a foundation.
If the ground is unstable, one option is to use patio
blocks under the perimeter of the base. Another option
is to pour a concrete foundation.
To install the furnace on a concrete foundation, refer
to Fig. 4 for dimensions and for the location of the
hollowed-out area for each model. A 4" to 6" thick
concrete slab works well; however, a thicker slab may
be used to obtain the desired door opening height.
If the area for the concrete slab is unstable and/or
affected by frost heaving, consider installing 2" closed-
cell insulation beneath the front portion of the slab and
under the area of the ground used for walking.

NOTE: The installation surface or foundation
must be noncombustible. The hot supply and
return lines must also be protected from possible
exposure to sunlight, fire or physical damage.
Foundations may consist of concrete, crushed
rock or patio blocks.
