is furnace may be installed as a Stand-Alone Central Furnace
or as a Supplementary Furnace in the US only. For Canadian in-
stallations, it may be installed as a Stand-Alone Central Furnace
Only.
If installed as a Central Furnace, this unit will have it’s own cen-
tral ducting system and will essentially be your primary heat
source. If installed as a Supplementary Furnace, the 1600EF will
assist an Electric, Gas or Oil Fired Furnace in heating your home
by utilizing the existing furnace’s duct work system. e 1600EF
must not be wired in conjunction with the existing furnace. e
outdoor furnace may be operated with the supplied wall thermo-
stat or a 24 volt thermostat that you supply yourself.
e furnace should be placed outdoors on a level noncombus-
tible base, preferably a 4’ x 8’ concrete pad, as close to the home
as clearances to combustibles will allow. If locating the furnace
more than 10 feet away from the home, a minimum of 6 feet of
Class “A” HT 2100 All Fuel 6 inch chimney pipe is required - Do
not place the furnace more than 40 feet away from the home.
Maintain all clearances stated in this manual.
Class “A” HT 2100 All Fuel 6” Chimney Pipe is recommended
for optimum performance and can be purchased from your local
dealer. A Chimney Base Plate should be installed over the ue
outlet and sealed to maintain weather resistance. A 2” clearance
to combustibles must be maintained from the pipe. We suggest
using either Simpson Dura-Vent or Metal Fab chimney products
for your installation.
If you choose to use single wall stainless, the ue temperatures
will be reduced which promotes the formation of creosote, pos-
sibly creating a re hazard. If you use single wall stainless pipe,
the minimum clearance to combustibles is 20”.
Attach the appropriate chimney pipe lengths to the chosen chim-
ney base plate and nish with a rain cap. Secure the chimney
with guy wires to each of the four anchors point on the furnace.
Your furnace requires it’s own chimney system and can not share
a ue with another appliance.
Once you have selected a location for the furnace and connect-
ed your furnace to a chimney and a 110 volt GFCI outlet, you
will need to commence an initial ring. DO NOT connect the
furnace to your duct work at this time. Your new furnace has a
protective coating of oil and paint on the surface which could
produce smoke or odors during the initial ring and will burn
o. Build a small re - DO NOT ll the rebox to it’s full capac-
ity for the initial burn. is initial ring allows the metals and
castings to cure.
Aer completing the ring and allowing it to cool, you are ready
to nish the installation. Refer to the remainder of this manual
for detailed instructions.
