Priming the Metering Pump (continued)

9. Run the pump until a solid stream of oil ows from the pump bleeder. This will bleed all air out

of the suction line, oil lter and pump head.

ATTENTION: For the metering pump to operate correctly, it is very important that the system

is entirely full of oil and all air is bled out. The burner will shut down if there is any air in the

system.

10. Open the mini ball valve at the outlet port of the pump head to allow the pressure oil line to be lled.

11. Close and tighten the bleeder on the pump.

12. Turn the priming switch to the burner (DOWN) position so that the pump stops running.

13. Disconnect the pressure oil line from the burner and position a container to catch oil which will ow

from the pressure oil line during pump priming.

14. Turn the priming switch to the prime (UP) position. The pump should start running immediately .

15. Run the oil pump until the proper ow of oil has been established, and the oil line has been completely

ushed out.

16. Turn the priming switch to the burner (DOWN) position so that the pump stops running.

17. Re-connect the oil line to the burner.

Vacuum Testing the Oil Pump

Vacuum testing the oil pump is a very accurate way to determine the following:

• The condition of the pump -- the ability of the pump to pull a vacuum and suck oil from the tank.

• The condition of the ttings, gaskets and seals from the ball valve to the pump -- these

components must all be airtight to avoid suction leaks.

The following procedure provides instructions for vacuum testing the pump and canister lter on

systems equipped with a ball valve.

ATTENTION: For the pump to pull and hold vacuum, it is critical that all ttings are airtight. If any of these

ttings are loose, the pump may not pull a vacuum or may lose the vacuum rapidly. It is also critical that all

ttings in the suction line, including ttings on the canister lter, are 100% airtight.

1. Follow the instructions to prime the pump (previous procedure).

NOTE: The pump will not pull a vacuum if the pump is dry. There must be oil in the gears of

the pump before the pump can pull a vacuum.

2. With the pump running, open the bleeder two to three full turns, and make sure that oil is owing

from the bleeder. DO NOT close the bleeder yet.

3. Refer to Figure 5A. Close the ball valve at the inlet to the canister lter. Observe the vacuum

gauge.

NOTE: The ball valve must have a stainless steel ball and should be pressure tested by the

manufacturer to ensure that it does not leak. If the ball valve leaks, the vacuum test will not be

accurate.

4. The vacuum should increase within 30 seconds to 15 inches of vacuum. When the vacuum

gauge reads 5 inches of vacuum, rst close and tighten the bleeder, then turn the pump off and

close the mini ball valve at the outlet port of the pump. Observe the vacuum gauge.

NOTE: If the pump will not pull at least 15 inches of vacuum, there is a very serious suction leak, or

the pump is damaged.
