Bard Furnace 2100-287 - Manual (Page 10)

procedures for this inspection are contained in the
instructions booklet and should be handled by the
qualified service agency only-
A general inspection of the furnace, the furnace area
and the vent piping system should be conducted on a
regular basis by the owner/occupant. This review
should include:
1. Make sure the furnace always has the minimum
clearance as detailed on the furnace rating
plate. Special attention must be given to these
items if any remodeling is done.
2. Make sure the vent piping system is in place and
is physically sound without holes, sags or dips.
3. Reviewing that the return air duct connection(s)
is physically sound, is sealed to the furnace
casing, and terminates outside the space
containing the furnace.
4. 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.
5. Inspect for any obvious signs of deterioration of
the furnace,
6. Periodic examinations of the vent piping system
should also be conducted by the owner on a
regular basis, preferably every monthly but at
least every two months during the heating
season.
7. Check the entire vent system for any blockage.
If any debris is present remove it.
8. Make sure that vent connector from the furnace
slopes upward and is physically sound without
holes or excesssive corrosion.
6.G THE FOLLOWING PROCEDURE SHOULD
BE FOLLOWED FOR THE PERIODIC
INSPECTION AS CONDUCTED BY THE
OWNER/OCCUPANT.
1. Set the wall thermostat to the OFF position or
lower the set point lever to a temperature will
below the existing room temperature. Shut off
electric power to the ftimace. A switch should
be mounted either on the outside of the furnace
or adjacent to the furnace for this purpose.
2. Remove the outer panel that has ventilating slots
in it.
3. Use flashlight or trouble light to observe the
burner compartment and burners. There should
be very miiumal scaling or sooting in this area.
Some loose debris may have fallen down on to
the floor of the heat exchanger form the tube
passageways, and this may be vacuumed out.
Also observe the sides of the heat exchanger
tubes for “hot spots” due to improper burner
alignment or overfiring and give particular
attention to any area where it looks like there
may be any deterioration from corrosion or
rusting. Observe for any corrosion on the burners
themselves. Should anything appear
questionable, contact your service agency.
4. Inspect the vent pipe the full distance from the
furnace to the vent terminal; observing for any
possible leakage that might result in products of
combustion entering the living area.
A
WARNING
Leakage of products of combustion into the
living area may result in asphyxiation resulting in
injury or death
5. Restore the electrical power to the furnace by
turning the switch back on. Adjust the
thermostat to call for heating operation.
6. Observe the main burners in operation. The
flame should be mostly "blue” with possibly a
little "orange” at the tips of the flames. The
flames should be in the center of the heat
exchanger tubes and not impinging on the sides
of the tubes themselves. Refer to Figure 3.
7. Observe the fire until the blower starts (there is a
normal delay period until the heat exchanger
warms up). There should be no change in the size
or shape of the flame. If there is any wavering or
blowing of the flame on the blower start-up. it is
an indication of a possible leak in the heat
exchanger. Turn off the gas valve in the gas line
leading to the furnace, and then the main
electrical switch to the furnace and call your
service agency.
8. Replace the slotted outer furnace door.
