Fuel Maintenance Checklist (CHECK ONCE A YEAR)
1)
Disconnect the fuel inlet line from the valve and place into a
bucket. Turn on your pump or open your gravity feed valve to
ensure there is a constant flow of fuel. This will indicate your fuel
filter and fuel pump are operating correctly.
2)
Remove the fuel inlet fitting from the valve and clean the screen
behind.
3)
Replace fuel inlet line to the fuel inlet fitting. Disconnect the fuel
outlet line and place a cup or small container underneath the valve.
4)
Turn the valve on to setting #1 and measure the fuel drip from the
fuel outlet of the valve. See page 23 for fuel measurements. This
will indicate that the valve is working correctly.
5)
Before re-connecting the fuel line, put some paper towel inside the
burner pot and blow into the fuel line so if any dirt is in there, it
will blow into the burner onto the paper towel.
6)
Re-connect the fuel line to the fuel outlet on the valve and wipe the
inside of the burner clean with the paper towel.
Cleaning the Burner
Carbon accumulates in the burner over a period of time and it must be
cleaned out or the air cannot get into the burner and the heater will not
operate correctly. It is especially important to ensure the air holes are clear.
If you are burning good quality fuel and the heater is burning efficiently
above the top burner ring this cleaning procedure will only be required once
a year. If there is rapid carbon build up in the burner pot, it indicates the
heater is not being operated correctly or the need for a barometric damper
adjustment. If you do not have a barometric you should install one to reduce
the air in the burner that is causing the carbon build up. This must be
rectified for satisfactory operation of the heater.
1)
Open the door and remove the burner ring and the superheater
2)
Insert the reamer tool provided into the fuel inlet hole. This will
prevent loose carbon from falling into the fuel inlet during cleaning.
3)
With a wire brush, scrape any loose carbon from the sides of the
burner.
