BASIC DESCRIPTION
The following steps are all needed for proper installation

as to any requirements, check with local authorities. Obtain
professional help where needed. All of the checks and
adjustments in the "Start-Up Procedures" are vital to the
proper and safe operation of your furnace. Please read our
instructions before you install and use your furnace. This will
help you obtain the full value from this furnace. It could also
help you avoid needless service costs if the answer to the
problem is found within this instruction manual.
Always consult your local heating or plumbing inspector,
building department or gas utility company regarding
regulations, codes or ordinances which apply to the
installation of a counterflow Direct Vented wall furnace.
Check the furnace nameplate, located in the burner

operate on the type of gas available (either natural or propane gas).
WARNING: CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected to the venting system being placed
into operation could result in carbon monoxide poisoning or death.
The following steps shall be followed for each appliance connected to the venting system being placed into
operation, while all other appliances connected to the venting system are not in operation:
1) Seal any unused openings in the venting system.
2) Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas
and Propane Installation Code, CSA B149.1 and
these instructions. Determine that there is no
blockage or restriction, leakage, corrosion and other
deficiencies which could cause an unsafe condition.
3) As far as practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system
are located and other spaces of the building.
4) Close fireplace dampers.
5) Turn on clothes dryers and any appliance not
connected to the venting system. Turn on
any exhaust fans, such as range hoods and
bathroom exhausts, so they are operating at
maximum speed. Do not operate a summer
exhaust fan.
DO NOT convert the furnace from natural gas to propane
gas or from propane gas to natural gas without the proper
manufacturer's gas conversion kit.
Your Counterflow Direct Vent Furnace draws air in at the
top of the furnace by the fan and discharged through the
grille near the floor. It is shipped ready to install on the
surface of a wall or recessed into a wall. Combustion air is
drawn in from the room where the furnace is located and
vented out the top of the furnace through listed vent piping
to a roof Direct Vent. Venting material is not supplied with
this furnace.
This appliance is equipped with a vent safety shutoff
system designed to protect against improper venting of
combustion products. Operation of this wall furnace when
not connected to a properly installed and maintained
venting system or tampering with the vent safety shutoff
system can result in carbon monoxide (CO) poisoning and
possible death.
6) Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat
so appliance is operating continuously.
7) Test for spillage from draft hood equipped appliances
at the draft hood relief opening after 5 minutes
of main burner operation. Use the flame of a match
or candle.
8) If improper venting is observed during any of the
above tests, the venting system must be corrected
in accordance with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 and/or Natural Gas and Propane
Installation Code, CSA B149.1.
9) After it has been determined that each appliance
connected to the venting system properly vents
when tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other
gas-fired burning appliance to their previous
conditions of use.
