Cleaning Burner
Carbon accumulates in the burner over a period of time and it must be cleaned out. It is
especially important to ensure the air holes are clear. If you are burning good quality fuel
and the heater is burning efficiently this cleaning procedure will only be required once a
year. If there is rapid carbon build up in the burner pot, it indicates an operation problem
or the need for a barometric damper adjustment. This must be rectified for satisfactory
operation of the heater. Refer to the operations, installation or troubleshooting sections of
this manual.
1) Open door.
2) Insert the reamer tool (provided) into the fuel inlet hole. This will prevent loose carbon
falling into the fuel inlet during cleaning.
3) With a wire brush, scrape any loose carbon from the sides of the burner.
4) Using a paper clip poke out the four rows of air intake holes on the sides of the burner to
ensure that they are clear.
5) Remove any loose carbon from the base of the burner.
6)
Remove the reamer and replace the burner ring and superheater.
Burner Replacement
BURNER REPLACEMENT INSTRUCTIONS
1. Remove the outer shield and the top of the heater as per coil install.
2. Chip out the old cement then remove the fittings under the heater and then drill out the
rivets that hold the original burner hanger plate in place. Use a high quality 3/16” dia drill
bit. Replace with the new burner and install using #10 machine screws and nuts, or 3/16
pop rivets.
3. Replace the fittings from under the heater and use Teflon tape on the threads, Note do
not over tighten the ¼ npt nipple that connects to the burner bottom.

consistency exact but oatmeal is a good consistency to aim for.
