a.
Select fan speed.
a.
Check vent pipe for blockage, such as bird nests,
twigs, leaves, etc. Check that the vent cap is
properly installed, and not placed too far down on
the vent pipe. Cap must be the same
manufacturer as the vent.
b.
The vent should terminate a minimum of 12 feet
above the floor plate. The top of the vent must be a
t least 2 feet above any obstacle within a 10 foot
radius, including the roof.
c.
All type "B" vents shall extend in a vertical direction
with offsets not exceeding 45 degrees. Any angle
greater than 45 degrees from vertical is considered
horizontal. Any offsets used should be a minimum
of 2-feet above the draft hood or as far away as
possible to allow venting to begin before any
restriction is encountered. The use of too many
offsets may also prevent proper venting.
d.
Use listed B/W type vent pipe. DO NOT use transite
or any other type of ceramic pipe for venting. DO
NOT use single wall vent pipe. When venting into a
masonry chimney, the chimney must be properly
lined and sized for this gas furnace. The use of type
"B" or flexible chimney liner is recommended.
e.
Check the connection on both the switch and the
gas valve. Tighten if necessary.
a.
Adjust pilot flame. Refer to "How to Care for Your
Furnace" section in this manual.
b.
Check installation. Casing may be distorted by
being fastened to an uneven opening or jammed
under the header. A restricted vent may create
expansion noise. Refer to "Vent Installation" section
in this manual.
c.
Check vent system for a blocked flue, excessive
down draft (wind) or negative pressure in room
caused by a ventilating fan or a fire in a fireplace.
d.
Furnace is possibly overrated, check for high gas
pressure at gas valve. (See 4B).
e.
Check the manifold gas pressure. Check the rate,
this appliance is manufactured for elevations up to
4,500 feet. It must be derated for operation above
4,500 feet.
f.
Check burner for obstructions. Install new burner
and pilot orifices.
g.
Remove pilot orifice, check and clean.
h.
DO NOT elevate the furnace off the floor unless
supported by the free standing accessory. Never
shear the legs. If replacing the furnace, bring the
vent pipe to the header. DO NOT raise the furnace
to the vent pipe. Legs must be flat on the floor
plate, never one in front of the other.
