5. Installing your Heater
Location
Plan your heaters location prior to installing to ensure the location chosen
will fit the specifications and safety clearances. Combustible material closer
to the heater then the specified safety clearances must be lined with
insulation or millboard and a metal liner with a .5” standoff for air
movement behind. Another alternative is using insulation or millboard and
ceramic tile. The wall behind the heater and the first length of chimney pipe
should also be lined with such material. See diagram below.
Safety Clearances
Above- 30”, In front- 18”, Sides- 12”, Below- 6”
Facing Direction
The heater ideally should face the bow or stern of the boat, particularly on a
sailboat. Fuel is gravity fed from the oil metering valve into the burner so if
the valve should drop below the level of the burner, the fuel would not flow
uphill into the burner, which will put out the fire. In a beam-facing
installation, the oil metering valve may have to be relocated to the side of the
heater. See diagram below. This will allow the heater to operate up to 15
degrees. If you need the valve mounted on the side, the heater would need to
be special ordered from the factory, please email us.

Note: the heaters valve & burner should be in line with the boats keel.
