MAINTENANCE
It is recommended that the furnace be checked yearly. At a minimum, this check should include the following items.
!WARNING:
To avoid electric shock, personal in- jury, or death, disconnect the electric power before performing any mainte- nance.
!WARNING:
Holes in the vent pipe or heat ex- changer can cause products of com- bustion to enter the home. Replace the vent pipe or heat exchanger if leaks are found. Failure to prevent products of combustion from being circulated into the living space can create potentially hazardous condi- tions including carbon monoxide poi- soning that could result in personal injury or death.
Combustion Air and Vent System
Check the combustion air and vent pipe to ensure that it is not damaged, corroded or blocked by debris. Any damaged section of vent pipe must be replaced, and any obstruction or blockage must be removed prior to operating the furnace.
Air Filter(s)
The installer should provide a filter rack for a high velocity type filter in the return air duct adjacent to the furnace. Filters should be changed or cleaned monthly during the heating season. New or newly renovated homes may require more frequent changing until the construction dust has been removed.
Lubrication
The bearings in the circulating air blower motors are
Condensate Drain Assembly
Be sure the condensate lines are free and open (i.e. avoid kinking hoses). Also make sure all hose clamps are tight to avoid drawing air into the system.
Blower Compartment
The blower compartment should be cleaned monthly during the heating and cooling seasons to remove any dirt and lint that may have accu- mulated in the compartment or on the blower and motor. Dirt and lint can create excessive loads on the motor resulting in higher than normal operating temperatures and shortened service life.
Heat Exchanger and Burner Maintenance The furnace should operate for many years without excessive soot buildup in the flue pas- sageways, however, the flue passageways, the vent system, and the burners should be in- spected and cleaned (if required) by a qualified serviceman annually to ensure continued safe operation. Particular attention must be given to identify deterioration from corrosion or other sources.
!WARNING:
Never operate the furnace without a filter in place. Dust and lint in the return air can build up on internal components, resulting in loss of effi- ciency, equipment damage, and pos- sible fire.
AIR FILTER(S) ARE NOT SUPPLIED WITH THE FURNACE AS SHIPPED FROM THE FACTORY. FILTERS FOR SIDE RETURN AND BOTTOM RETURN APPLICATIONS ARE AVAILABLE FROM NORDYNE DISTRIBUTORS.
SYSTEM OPERATION
INFORMATION
Proper maintenance is most important to achieve the best performance from a furnace. Follow these instructions for years of safe, trouble free operation.
•Do not place combustible materials on or against the furnace cabinet or the vent pipe.
•Do not store gasoline or any other flam- mable vapors and liquids in the vicinity of the furnace.
