CHAPTER 8
INSTALLATION OF THE HEATMOR™ FURNACE
Installation should be performed by a qualified installer and will comply with all the
requirements of the authority having jurisdiction over the installation.
Principles
1) Need to have an airtight seal between the concrete base and the perimeter of the
firebox base.
2) Need to seal the perimeter of the entire HEATMOR™ so rodents are not able to find a
home inside the HEATMOR™.
3) Need to lift the HEATMOR™ without damaging it.
Equipment Required
1) It is
not
possible to lift a HEATMOR™ with the forks of a
forklift under the HEATMOR™. It
must be lifted from
the
top
, by the lifting hook. A crane or heavy backhoe works
best.
Placing the HEATMOR™ on the Concrete Base
2) Before setting the HEATMOR™ onto the concrete base, it
is a good idea to place a solid sheet of the proper
“reflective air foil” (also called bubble foil) between the
concrete and the HEATMOR™. This will absorb ridges in
the concrete and make it easier to apply caulking around
the inside perimeter of the base of the HEATMOR™. This
reflective foil will also reflect escaping heat up into the
sand,
and help prevent air leaks into the firebox if cement
cracks.
3) Make sure the total area of the base (where the sand is
going) is on solid
concrete. Do not let the base extend past the hole in the concrete where the
lines come in.
4) After the HEATMOR™ is in place perform the following;
Caulking around the Firebox Base
A) One person should get into the HEATMOR™.
B) Apply a substantial bead of caulking around the entire inside perimeter of
the base. This will give an airtight seal so no air will seep through the sand.
This should require about three tubes of High Temperature Silicone.
Caulking around the Outside Perimeter of HEATMOR™
C) With a sharp knife, trim any excess bubble foil that
extends past the base of the HEATMOR™.
D) Apply a bead of caulking around the entire outside
5) Remove transport plugs from relief vent on the roof of your
furnace, supply ball valve, and return pipe on the back of
your furnace. (3 different plugs)
6) Close supply valve located on the back of your furnace.
