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 venting system.
2. Inspect the venting system for proper size and horizontal
pitch, as required in the National Fuel Gas Code, ANSI
Z223.1-2002/NFPA 54-2002 or the CSA B149.1, Natural
Gas and Propane Installation Code 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 appli-
ance 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-
2002/NFPA 54-2002 and/or CSA B149.1, Natural Gas and
Propane Installation Code.
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 appli-
ance to their previous conditions of use.

FIRE AND EXPLOSION HAZARD
Failure to follow this warning could result in fire, property
damage, personal injury, or death.
Solvent cements are combustible. Keep away from heat,
sparks, and open flame. Use only in well-ventilated areas.
Avoid breathing in vapor or allowing contact with skin or
eyes.
In Canada, construct all combustion-air and vent pipes for this unit
of CSA or ULC listed schedule-40 PVC, PVC-DWV or ABS-
DWV pipe and pipe cement. SDR pipe is NOT approved in
Canada.
In direct vent (2-pipe) systems, combustion air and vent pipes must
terminate together in same atmospheric pressure zone, either
through roof or sidewall (roof termination preferred), using acces-
sory termination kit. See Table 8 for required clearances.
→
In non-direct vent (1-pipe) system, vent pipe termination must be
installed with adequate clearances to building openings and
equipment to comply with national and local codes. See Table 9
for required clearances.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in property
damage, personal injury, or death.
All combustion-air and vent pipes must be airtight and
watertight. Pipes must also terminate exactly as shown in Fig.
40 for direct vent (2-pipe) system and Fig. 41 for non-direct
vent (1-pipe) system.
→
An abandoned masonry chimney may be used as a raceway for
properly insulated and supported combustion-air (when appli-
cable) and vent pipes. Each furnace must have its own set of
combustion-air and vent pipes and be terminated individually, as
shown in Fig. 43 for Direct Vent (2-Pipe) system and Fig. 44 for
Non-Direct Vent (1-Pipe) system.
→
A furnace shall not be connected to a chimney flue serving a
separate appliance designed to burn solid fuel.
Other gas appliances with their own venting system may also use
the abandoned chimney as a raceway providing it is permitted by
local code, the current edition of the National Fuel Gas Code and
