VENTING
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.
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.

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:
It is imperative that control compartments, burner, and
circulating air passageways of the furnace be kept clean.
16. Do not install in a closet, alcove, or small hallway where
the furnace could be isolated from the space to be heated
by closing a door.
17. Do not put anything around the furnace or vent cap that
will obstruct the flow of combustion and ventilation air.
18. The appliance, when installed, must be electrically
grounded in accordance with local codes or, in the
absence of local codes, with the latest edition of National
Electrical Code, ANSI/NFPA 70. In Canada, use CSA
C22.1 Canadian Electrical Code.
19. Never operate this furnace without the sight glass in
place or with the glass broken or missing.
20. If it is suspected that rising water may enter the furnace,
turn off the gas immediately. Do not use this appliance
if any part has been under water. Immediately call a
qualified service technician to inspect the appliance and
to replace any part of the control system and any gas
control which has been under water.
21. It is necessary to replace damaged gaskets or sealing
material within the vent or air intake system. Failure to do
so may result in property damage, personal injury or loss
of life.
22. Any safety screen or guard removed for servicing must
be replaced prior to operating heater.
23. A gas appliance must not be connected to a chimney flue
serving a separate solid-fuel burning appliance.
