OPERATION
GENERAL
Never operate the heater unless the tank is filled with water and a temperature and pressure relief valve is installed.
FILLING
1.Oil burner electrical disconnect switch should be in the "OFF" position
2.Close the heater drain valve.
3.Open a nearby hot water faucet to allow the air in the system to escape.
4.Fully open the cold water inlet valve, filling the heater and piping.
5.Close the hot water faucet as water starts to flow from the opening, Leave the cold water inlet valve fully open. The heater is now ready to
START-UP
The following checks should be made by the installer when the heater is placed into operation for the first time:
1.Check all factory and field made water, oil and electrical connections for tightness. Also check flue gas disposal provisions on top the heater.
•Repair any water and oil leaks. Tighten electrical and flue connections as necessary.
2.Where the water heater or water heating systems includes a circulating pump, it may need to be lubricated before operated. The tube of lubricant supplied with the pump includes directions for use.
•Field installed circulating pumps should be all bronze construction.
Be sure the oil burner, related piping, valves and controls are in place, adjusted and ready for operation before turning on the electricity.
3.Adjust the heater mounted control as follows:
•THERMOSTAT (adjustable) set for desired water temperature.
•It is suggested the thermostat be turned to the lowest setting which satisfies the hot water requirements of the system. This helps minimize scale formation in the heater.
•HIGH LIMIT (not adjustable, manual reset) factory set to cutout at 195° F (90.5°C).
•If the high limit is actuated, the safety primary control will cause the oil burner to shut down. See SAFETY PRIMARY CONTROL, page 21.
•To reset the safety primary control, depress and hold the red button on the control for 30 seconds until the LED flashes twice.
•Depress red button one time only. If burner does not operate after depressing red button one time, call service man.
4.Turn on the oil burner electrical disconnect switch.
5.The heater will begin normal operation on the thermostat's "call for heat".
