Regular Dealer Maintenance - Trane UE1 User's Information Manual

Never stop the cooling system by shutting off
the main power.
If the main power to your air conditioner is ever disconnect-
ed for more than three hours, turn off the thermostat. Then
wait for at least three more hours after the power has been
restored before turning the thermostat back on. Failure
to follow this procedure could result in damage to your air
conditioning system.
1. GENERAL INSPECTION – Examine the furnace in-
stallation for the following items:
a. All flue product carrying areas external to the fur-
nace (i.e. chimney, vent connector) are clear and free
of obstruction.
b. The vent connector is in place, slopes upward and is
physically sound without holes or excessive corro-
sion.
c. The return air duct connection(s) is physically
sound, is sealed to the furnace and terminates out-
side the space containing the furnace.
d. The physical support of the furnace should be sound
without sagging, cracks, gaps, etc., around the base
so as to provide a seal between the support and the
base.
e. There are no obvious signs of deterioration of the
furnace.
The following warning complies with State of California law, Proposition 65.

HAZARDOUS GASES!
EXPOSURE TO FUEL SUBSTANCES OR BY-PRODUCTS
OF INCOMPLETE FUEL COMBUSTION IS BELIEVED BY
THE STATE OF CALIFORNIA TO CAUSE CANCER, BIRTH
DEFECTS, OR OTHER REPRODUCTIVE HARM.
2. BLOWERS – The blower size and speed determine the
air volume delivered by the furnace. The blower mo-
tor bearings are factory lubricated and under normal
operating conditions usually do not require servicing.
Annual cleaning of the blower wheel and housing is
recommended for maximum air output, and this must
be performed only by a qualified servicer or service
agency.

SAFETY HAZARD
UNIT IS EQUIPPED WITH A BLOWER DOOR SWITCH
WHICH CUTS POWER TO BLOWER AND GAS VALVE
CAUSING SHUTDOWN WHEN DOOR IS REMOVED. UNIT
MUST NOT BE ALTERED TO ALLOW OPERATION WITH
THE BLOWER DOOR REMOVED. OPERATION WITH
DOORS REMOVED OR AJAR CAN PERMIT THE ESCAPE
OF DANGEROUS FUMES. ALL PANELS MUST BE SE-
CURELY CLOSED AT ALL TIMES FOR SAFE OPERATION
OF THE FURNACE. FAILURE TO FOLLOW THIS WARNING
MAY RESULT IN PERSONAL INJURY, PROPERTY DAM-
AGE, CARBON MONOXIDE POISONING, OR DEATH.

ignition device that automatically lights the burners.
Please note that it is very fragile and should be han-
dled with care.

Regular Dealer Maintenance

Do NOT touch igniter. It is extremely hot.
4. BURNER – Gas burners do not normally require
scheduled servicing, however, accumulation of foreign
material may cause a yellowing flame or delayed igni-
tion. Either condition indicates that a service call is
required. For best operation, burners must be cleaned
annually using brushes and vacuum cleaner.
Turn off gas and electric power supply. To clean burners,
remove top burner bracket and lift burner from orifice.
NOTE: Be careful NOT to break igniter when removing
burners.
Clean burners with brush and/or vacuum cleaner. Reas-
semble parts by reversal of the above procedure.
NOTE: On LP (propane) units, some light yellow tipping of
the outer mantle is normal. Inner mantle should be bright
blue.
Natural gas units should not have any yellow tipped flames.
This condition indicates that a service call is required. For
best operation, burners must be cleaned annually using
brushes and vacuum cleaner.
NOTE: On LP (propane) units, due to variations in BTU
content and altitude, servicing may be required at shorter
intervals.
5. HEAT EXCHANGER / FLUE PIPE – These items must
be inspected for signs of corrosion, and/or deterioration
at the beginning of each heating season by a qualified
service technician and cleaned annually for best opera-
tion.
6. CIRCUIT PROTECTION – If blower or gas valve fail
to operate, the cause could be the circuit breaker or
a loose or blown fuse. Replace fuse or reset circuit
breaker.
