Balance the System
The air distribution system should be balanced,
using in-line duct dampers if employed, to provide
for satisfactory air delivery to room. It is recom-
mended that dampers in registers not be used for
balancing the system.
SERVICE INSTRUCTIONS
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause im-
proper and dangerous operation.
Verify proper operation after servicing.
Motor Lubrication
The circulating air blower motor and vent blower is
permanently lubricated and does not require periodic
lubrication.
Burner Cleaning
The burners used in this furnace are specially
designed to be non-linting and should not require
periodic cleaning. In the event that cleaning does
become necessary, use the suction hose of a
suitable vacuum cleaner to remove dirt and lint. Be
careful not to damage the ignitor or sensor rod
during cleaning.
Flue Gas Passageways
Periodic cleaning of the heat exchanger and flue gas
passageways is not necessary and is not recom-
mended under normal circumstances.
REPLACEMENT PARTS
Should it be necessary to replace any component
parts, these may be obtained through an authorized
dealer, who is experienced and can be of assis-
tance. Information on the nearest Distributor may be
obtained directly from the company shown on the
furnace rating plate.
Only genuine authorized replacement parts
should be used. Substitute parts should not be
used, as they may not be the same in opera-
tional and safety characteristics.
Following major service or replacement of functional
parts, it is recommended that the furnace be
operated in the various modes to insure that per-
formance is normal and control components are
functioning properly.

functional parts and those that might require re-
placement. The parts listed are by part name
