FURNACE & AIR DUCTS
• The furnace should be inspected annually by a licensed
HVAC technician. Table 1 below contains suggested
inspections and frequency of maintenance.
• Homeowners should perform frequent visual inspections of
the furnace for obvious signs of deterioration. The furnace
should be secure without sagging, cracks gaps, etc around
the base. The return air duct connection(s) is secured
and sealed to the furnace cabinet and terminates outside
the area containing the furnace. Any signs of damage or
loose connections should be repaired by a qualified HVAC
technician.
VENTING SYSTEM
• For proper and safe operation, this furnace requires
unrestricted airflow for combustion and ventilation. Inspect
for blocked or obstructed air openings on or around the
furnace (at the terminations outside the house), and the
space around the furnace.
• The furnace venting system should be inspected annually by
a licensed HVAC technician. Vent pipe must slope upwards
and be physically secured without holes or corrosion. Any
corroded section of vent pipe must be replaced, and any
obstruction or blockage must be removed by the technician.
• Flue passageways and the vent system should be inspected
and cleaned (if required) by a licensed HVAC technician
annually to ensure continued safe operation.
• Existing masonry chimneys should be inspected and relined
(if necessary) by a licensed HVAC technician.
BLOWER & FILTER
• It is recommended that the blower compartment be cleaned
of dirt or lint that may have accumulated in the compartment
or on the blower and motor as part of the annual inspection.
• Keep air filters cleaned. It is recommended that the furnace
air filter be checked at least once a month. Clean or replace
filter to maintain proper airflow and achieve maximum
efficiency.
• Furniture and drapery should be arranged so that the
supply air registers and return grilles are not obstructed.
FLAME ROLL-OUT LIMIT SWITCH
Verifies the inducer motor is drawing combustion gases
through the heat exchanger properly. The temperature
switch prevents furnace operation in the event of flue or
combustion air passageway blockage, or improper inducer
motor operation. If blower is running and control board is
showing Open Limit flash code, check the following:
1. Set the thermostat to OFF or lowest setting.
2. Turn OFF all electrical power to the furnace.
3. Allow the furnace to cool if recently operating.
4. Carefully reach in and re-set the roll-out limit switch located
on the gas burner head by depressing button on top of
limit. Note: If limit doesn’t re-set it may require more time
to cool.
5. Check flue passageway for any blockage and clean as
required.
6. Restore electrical power to the furnace.
7. Set thermostat to initiate a call for heat.
8. Monitor the furnace and inducer motor for any unusual
operation or noise. Allow the unit to operate for 15-20
minutes to ensure proper operation.
9. If flame roll-out limit trips consult a licensed HVAC
technician for service.
BURNER OPERATION
Perform the startup instructions on page 6. The igniter should
ignite the burner. The sightglass should produce a dull orange
glow after the ignitor is deenergized.
NEW CONSTRUCTION
Operating gas furnaces in construction environments can
cause a variety of problems within the furnace and may
significantly reduce the life or the performance of the furnace.
Therefore operating the furnace during construction is not
permitted and will void the warranty.
• Before occupancy, the furnace shall be inspected and
approved by applicable local authority even if this results
in redundant inspections.
• The duct work must be inspected and cleaned if found to
contain any construction debris.
• The filter must be replaced or cleaned and the furnace
must be inspected by a licensed HVAC technician. The
furnace must be cleaned and/or repaired if found to be
dirty, damaged, or malfunctioning in any way.
