Your heater is a natural draft appliance and it creates its draft pressure like a chimney in a
wood stove. The rising, heated air in the stack pulls fresh air into the heater as it rises up
the stack and exits the flue cap. The greater the draft pressure the more able the heater
will be to resist strong winds, overcome flue elbows (that inhibit draft) and the hotter you
will be able to get your heater without sooting.
A CO alarm should be installed in the boat along with the Dickinson high heat shut-off
#02-210, if you are unable to fully attend the stove and still be on board the boat.
If when lighting the heater, the smoke from the burning tissue is sucked up the chimney
then the boat has a positive pressure (good draft), but if the smoke comes out of the
heater before closing the door then the boat has a negative pressure. Air is drawn in by
way of the chimney instead of a vent and will have to be corrected in order for the heater
to have a good draft and operate correctly.
Draft Assist Fan
During start up, at higher settings or during windy conditions, you may 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 but it is convenient during start up and some heater installations are
accomplished with only the minimum flue heights or with flue elbows that can inhibit the
draft. Due to these possibilities, the combustion assist fan has been installed in your heater.
1 To speed start-up and pre-heating.
2 To ensure complete combustion and avoid flooding the burner when the fuel supply is
turned up too quickly.
3 To limit the effects of back draft should this occur during windy conditions.
4 To operate the heater at high fire settings without carboning or smoking.
Note: Operating the fan can deliver too much air and cause the burner to run too lean (too
much air in the fuel to air mixture). When using the fan try to give as much air as possible
until some of the flames drop down and burn below the top burner ring, then back it off
slowly until all the flames are again burning above the burner ring.
