6 WOODMASTER OUTDOOR FURNACES • OWNER'S MANUAL
Block or Pad Supports
Under normal conditions four cement blocks are all that is required to
support the furnace. Blocks should be at least 6 inches wide, 10 inches long,
and 3 inches thick.
Under very soft conditions a concrete pad may be needed. To install the
outdoor furnace on a concrete foundation, refer to the illustration for
dimensions and for the location of the hollowed-out area for each model. A
4" to 6" (10 to 15 cm) thick concrete slab works well; however, a thicker slab
may be used to obtain the desired door opening height. Always use a non-
combustible base.
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.
CAUTION
CALL BEFORE YOU DIG . Do not use any combustible materials for the foundation .
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 that may be caused by an occurrence outside the outdoor furnace
enclosure . Foundations may consist of concrete, crushed rock or patio blocks .
Do not use any combustible
materials for the foundation.
CAUTION
Outdoor furnace must be installed on a noncombustible surface or foundation that incorporates an enclosure
that will prevent supply and return lines from possible exposure to sunlight, fire, or physical damage that may be
caused by an occurrence outside the outdoor furnace enclosure. Foundation may consist of concrete, crushed
rock, or patio blocks.

Foundation Advantages
Installing the outdoor furnace
on a foundation offers many
advantages. The outdoor
furnace is less likely to
move due to frost heaving.
A foundation keeps the area
directly around the outdoor
furnace free of standing water.
It can also raise the furnace up
to provide a more comfortable
height of the firebox door
opening.
