Maintenance Tool
Cleaning Rod
Tools
Included with each new furnace
are tools that are invaluable for
maintenance and cleaning. Use
the maintenance tool to clean the
firebox and to remove ash from the
Reaction Chamber. The maintenance
tool is also used for cleaning the
firebox and door frame. The cleaning
rod can be used to break up heavy or
solidified ash in the firebox. It is also
used to clean the heat exchangers.
The Refractory/Chimney Tee
cleaning tool is used to clean ash
from the Reaction Chamber and to
clean the chimney tee.
Refer to the Maintenance section for
more information.
Foundation
The outdoor furnace may be installed directly on stable, level ground without
the necessity of a foundation, although 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 and can help to keep unwanted
pests out. It can also raise the furnace up to provide a more comfortable
height of the firebox door opening.
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 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.
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
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.
