MAINTENANCE
Homeowner Information
, On some closet installations, the return air
opening to the furnace may be on the floor,
in the door, in the side wall of the closet, or
any combination of these. The upper grille on
the front of the furnace admits return air to the
blower. Return air must be provided back to
the circulating blower in order to provide air
distribution. See Figure 38.
. Filters - At least twice each season (more often
in dusty areas) remove and clean the air filters
with a vacuum or with warm water and soap.
Reinstall when dry. Also clean dust and lint
around furnace and in the furnace vestibule.
. During extremely cold weather, ice may form
on the furnace roof jack (Figure 39). Small
amounts of ice forming on the roof jack
will present no problems to proper furnace
operation. Excessive ice formation could
restrict the combustion air supply to the
burner, causing inefficient burner operation.
If excessive ice has formed on the air inlet or
exhaust portions of the roof jack, it must be
carefully removed.
Installer Information
All furnaces need periodic service at the
beginning of each heating season. Call your
serviceman to:
. Remove the air circulator and clean all dust
and lint from the unit with a stiff bristle brush.
. Inspect the combustion chamber blower
compartment, flue collar and Roof Jack.
. Check the gas valve (if applicable) and fuel
line connections for leaks.
. Make any adjustments necessary for good
operation.
WARNING:
Use of furnace or air conditioning
components that are not included
in the certification of this appliance
may create a hazard, invalidate
the certification, and in many
states, make installations illegal.
Listed NORDYNE air conditioning
components are specified on the
furnace label.
Additional Oil Furnace Maintenance
In addition to the preceding, the following should
be performed by a qualified service contractor
at least once each season for oil-fired furnaces:
. Replace the oil nozzle with the type nozzle
specified for your furnace.
. Clean, adjust and replace if necessary the
spark electrodes.
. Reset the nozzle/drawer assembly to factory
specifications.
Clean the inside of the furnace heat exchanger
and replace the combustion liner if necessary.
Clean or replace the oil filter element at the
oil tank.
. Adjust the burner for top efficiency and check
to make sure all fittings are leak-tight.
