Lanair HI140 - Manual (Page 78)

23. Clean all lines, Fittings and parts internally before assembly. Rust, metal shavings, or
dirt will clog the burner nozzle.
24. To prime the pumping system, disconnect the union on the pick up tube, and fill the line
with new oil. Re-tighten the union. Fill the primary strainer canister with new oil. Make
sure all plumbing connections are completed and tightened. Fill the supply tank with the
recommended fuel. Disconnect the power supply at the pump, which is supplied from
the furnace. Temporarily connect a 120 V circuit to the pump, causing it to run.
Caution: Do not connect the temporary power and the permanent power supply lines
both to the pump motor both at the same time as this will cause a short, damaging or
burning out components.
Open the bleeder port on the pump. Start the pump. When the air is purged, a steady
stream of oil will exit the bleeder port. Close bleeder port.
Make sure to disconnect the fuel line from the burner, and put the fuel line in a bucket to
catch the oil. Let the oil run until you get a clear stream of oil (no air bubbles). Turn the
pump off. Reconnect the fuel lines and electrical connections to the heater. Make sure
the waste oil switch on the burner is turned on (red light on). Turn the thermostat up
until it calls for heat. Let the furnace run for 15 minutes.
Maintenance Schedule
Weekly: Drain water and sludge from your fuel supply tank. The water and anti-
freeze settles to the bottom of the tank. When draining, only open the
valve a small amount. If you open the valve all the way you will drain oil
instead of water.
Monthly:
Clean the oil supply tank filter #8748 and check valve 8662.
Clean the primary strainer # 9807. New elements and o-rings are
available. Call the Lenan Corporation Service Department (800) 753-1601.
Clean the pump strainer located under the pump cover. New gaskets are
available. Call the Lenan Corporation Service Department (800) 753-1601.
See the owner’s manual for more details.
Yearly:
Clean the entire pumping system, filters, lines and oil supply tank. Flush
the pump with No. 1 fuel oil to clean out any sludge deposits that may
have accumulated.
Do not run the supply pump dry; this will void the warranty.
