9.0 Gas Heat
Section
Maintenance -
Models RDCA
and RDDA
This gas heater will operate with a minimum of maintenance. To ensure long
life and satisfactory performance, a heater that is operated under normal con-
ditions should be inspected and cleaned at the start of each heating season.
If the heater is operating in an area where an unusual amount of dust or soot
or other impurities are present in the air, more frequent maintenance is recom-
mended.
When any service is completed, be careful to reassemble correctly to ensure
that no unsafe conditions are created. When re-lighting, always follow the light-
ing instructions on the furnace.
8.0 Thermal
Expansion
Valves
NOTE: Thermostatic expansion valves for RDCA and
RECA are the same as for Model RCA. Thermostaticl
expansion valves for RDDA and REDA are the same
as for Model RDA.
IMPORTANT: Thermostatic expansion valve P/N's listed here are for use
with R22 refrigerant only. If the system is charged with R407C refrigerant
(check the rating plate), contact your distributor or the factory service depart-
ment for replacement information.
