intended temperature rise range with a duct system which
has an external static pressure within the allowable range,
as specified on the unit rating plate and in the GAS HEAT
START UP section of this manual.
7. When this furnace is installed so that the supply air duct
supplies air to areas outside the space containing the
furnace, the return air duct must be sealed to the furnace
casing and terminate outside the space containing the

to inspect the furnace and to replace all gas controls,
control system parts, electrical parts that have been wet
or the entire furnace if deemed necessary.
12. The user shall annually inspect the furnace installation to
verify the following safety related items:
a. All flue-gas carrying areas external to the furnace are
clear and free of obstructions.
b. The flue pipe is in place and physically sound without
holes or other damage.
c. The return-air duct connection is physically sound, is
sealed to the furnace casing, and terminates outside the
space containing the furnace.
d. The physical support of the furnace is sound without
sagging, cracks, gaps, etc., around the base so as to
provide a seal between the support and the base.
e. There are no obvious signs of deterioration of the
furnace.
f. The burner flames are stable and uniform, refer to
FIGURE 41 - Burner Flames illustrating proper flame
appearance for comparison.
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow instructions could result in severe
personal injury or death due to carbon-monoxide
poisoning, if combustion products infiltrate into the
building.
Check that all openings in the outside wall around the
vent (and air intake) pipe(s) are sealed to prevent
infiltration of combustion products into the building.
Check that furnace vent (and air intake) terminal(s) are
not obstructed in any way during all seasons.
