Foundation; Trench - Heatmaster G100 Operation And Maintenance Manual

Installation should be performed by a qualified installer and will comply with all
Find the footprint of the furnace in the Appendix of this manual
Inspect the ground conditions that you intend to install your furnace on.
A cement pad of 4-6" in thickness should be used.
Cement pads should be a little bigger than the actual furnace, with about a 4' extra
length front and back so you have a solid working area.
The furnace can also be placed on 4 cement blocks not less than 6" wide X 10" long
and 3" thick. Place your blocks so the legs will stand on the center of the blocks.
- The furnace may be installed on a combustible floor provided a noncombustible mate-
rial such as metal or masonry liner is used in the following areas:
- Underneath the furnace
- At least 16" in front of the furnace and 8" on each side of the firebox and lower
combustion chamber doors.
SteelTech Inc recommends the
trench to be 24" to 36" deep and
wide enough to install your water
lines. If possible, have a gradual
slope in your trench to allow drain-
age away from your lines and out of
the trench bottom.
Most insulated underground pipe
has room for electrical wire in it. If it
does not, place electrical supply in
bottom of trench and cover with 6
inches of dirt.
A minimum of R8 insulation value is
recommended and a water tight va-
por barrier such as PVC pipe or
drain tile to encase your insulation
is a must.
NOTE: If you are installing your water lines under an area where vehicles will
cross, you should increase your depth of the trench and use a schedule pipe over your
lines to reduce the pressure generated on the lines.
