IV. LIMIT CONTROL CHECK
After furnace has been in operation for at least 15 minutes, restrict
Remove restriction, and burner should come back on in a few minutes.
V.FOR YEAR-ROUND AIR CONDITIONING
This furnace is designed for use in conjunction with cooling equipment to provide
VI. HEATING
The blower speed is factory set to deliver required airflow at normal duct static pressure.
VII. COOLING
The blower speed may be field adjusted to deliver required airflow for cooling application. (See Table 5.)
WARNING: Before performing any service functions, unless operations specifically require power to be on, make sure all utilities are turned off upstream of appli- ance. Failure to comply with this warning will cause a fire hazard and/or bodily harm.
WARNING: To avoid personal injury, make sure elec- trical supply power is off before servicing.
→I. GENERAL
In order to keep this furnace in good operating condition and to maintain its warranty, the furnace MUST be serviced on an annual basis. This servicing includes a nozzle change, a burner inspection, a visual check of tube passages through flue outlet and cleanout ports, and a visual inspection of combustion chamber when burner is removed.
Depending on above inspection, service could also include a cleaning and vacuuming of heat exchanger tubes and possibly the heat exchanger drum section.
Removal of any heat exchanger components which are sealed by gaskets requires replacement of gasket.
WARNING: Failure to replace any heat exchanger gas- kets with new gaskets when any heat exchanger plates or covers are removed could lead to heat exchanger leakage, sooting, and/or a hazardous condition capable of causing bodily harm.
This furnace should never be operated without an air filter. Disposable filters should be replaced at least once a year. If equipped to provide cooling, filters should be replaced a minimum of twice a year. Permanent filters should be cleaned at least twice a year.
ALWAYS KEEP MAIN OIL VALVE TURNED OFF IF BURNER IS SHUT DOWN FOR AN EXTENDED PERIOD OF TIME.
II.OIL BURNER
Contact your service technician for service.
Lubricate burner motor with SAE 10 oil. Once each year, pour 2 teaspoons of oil slowly into each oil cup.
To maintain proper performance, oil burner nozzle must be replaced once a year.
