WARNING: HIGH VOLTAGE DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
CAUTION: IF YOU MUST HANDLE THE ITNITOR, HANDLE WITH CARE. TOUCHING THE IGNITOR BODY WITH BARE FINGERS, ROUGH HANDLING, OR VIBRATION COULD RESULT IN EARLY IGNITOR FAILURE. ONLY A QUALIFIED SERVICER SHOULD EVER HANDLE THE IGNITOR.

AIR FILTER
WARNING: NEVER OPERATE FURNACE WIHTOUT A FILTER INSTALLED AS DUST AND LINT WILL BUILD UP ON INTERNAL PARTS RESULTING IN LOSS OF EFFICIENCY, EQUIPMENT DAMAMGE, AND POSSIBLE FIRE.
Improper filter maintenance is the most common cause of inadequate heating or cooling performance. Filters should be cleaned (permanent) or replaced (disposable) every two months or as required. It is the owner's responsibility to keep air filters clean.

FILTER REMOVAL PROCEDURE
Media Air Filter or Electronic Air Cleaner Removal
Horizontal Unit Filter Removal
INDUCED DRAFT AND CIRCULATION BLOWERS
CONDENSATE DRAINAGE SYSTEM (QUALIFIED SERVICER ONLY)
The drain tubes, standpipe, and field supplied drain line must be checked annually and cleaned as often as necessary to ensure proper condensate drainage.
FLAME SENSOR (QUALIFIED SERVICER ONLY)
Under some conditions, the fuel or air supply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator, causing a drop in the flame sensing signal. If this occurs, a qualified servicer must carefully clean the flame sen

TEST EQUIPMENT
Proper test equipment for accurate diagnosis is as essential as regular hand tools. The following is a must for every service technician and service shop.
Dial type thermometers or thermocouple meter (optional)
Amprobe
Volt-Ohm Meter
Inclined Manometer
Water Manometer (12")
Other recording type instruments can be essential in solving abnormal problems, however, in many instances they may be rented from local sources.
Proper equipment promotes faster, more efficient service and accurate repairs resulting in fewer call backs.
HEATING PERFORMANCE TEST
CAUTION: ALWAYS CONNECT A MONOMETER TO THE OUTLET TAP AT THE GAS VALVE BEFORE ADJUSTING THE PRESSURE REGULATOR. IN NO CASE SHOULD THE FINAL MANIFOLD PRESSURE VARY MORE THAN PLUS OR MINUS .3 INCHES WATER COLUMN FROM 3.5 INCHES WATER COLUMN FOR NATURAL GAS
To adjust the pressure regulator on the:
Since normally propane gas is not installed with a gas meter, clocking will be virtually impossible. The gas orifices used with propane are calculated for 2500 BTU per cubic foot gas and with proper inlet pressures and correct piping size, full capacity w
With propane gas, no unit gas valve regulator is used; however, the second stage supply line pressure regulator should be adjusted to give 10" water column with all other gas consuming appliances running.
The dissipation of the heat transferred to the heat exchanger is now controlled by the amount of air circulated over its surface.
The amount (CFM) of air circulated is governed by the external static pressure in inches of water column of duct work, cooling coil, registers, etc., applied externally to the unit versus the motor speed tap (direct drive) or pulley adjustments of the mot
A properly operating unit must have the BTU per hour input and CFM of air, within the limits shown to prevent short cycling of the equipment. As the external static pressure goes up, the temperature rise will also increase. Consult the proper tables for t
