8. Draft Assist Fan Installation
The 12v draft assist is not needed for operation but highly recommended as
it will help to vaporize the fuel and give more control in burning the heater
as clean as possible. The fan is a 12v DC fan that the draw is .17amp. The
fan is 12v and if 24v or 32v is needed, resistors are available. This fan is
rated for 8000 hours and is only for start up and for higher temperature
settings as using the fan all the time will burn it out prematurely and make
hard carbon deposits inside your burner pot clogging up the air holes causing
the heater to not operate correctly.
When turning the fan on, turn it up to a faster speed first, then you can adjust
it back down to a slower speed as this gets the fan blade going.
Whenever possible, ensure a weatherproof connection between wires with
solder or the appropriate connectors with 18awg wire. The motor mount
‘bushing’ washers should be placed in between the mount bracket and the
main housing NOT between the mount bracket and the head of the fastener.

During start up, operating at higher settings or during windy conditions, you
want to use the combustion assist fan on your heater to artificially boost the
draft. Your heater should operate without the use of the fan on lower
temperature settings. Some heater installations with only the minimum flue
heights or with flue elbows that inhibit the draft may need the use of the fan
more often.
