Installation checklist:
When choosing the place for the device, remember the need to detach it for service.
Ensure sufficient air supply for the device..
Ensure sufficient circulation of air in the boat.
Openings for incoming heating and ventilation air are placed at a minimum distance of 16" away
from the fuel fill fitting and the tank breather fitting.
The rated voltage of the device is 12 VDC, 12.6+ VDC required at unit prior to start.
The current for the device is taken directly from the battery terminals or a battery buss using as
short of cables as possible. See table 2.

An inline fuse is installed in the positive power cable near the battery.
The fuel for the unit is from a separate tank pickup, not through the engine pickup.
Install a filter in the fuel line. Note the need for replacing the fitter periodically.
Cut the fuel line to a suitable length during installation. Ensure that the fuel line joint surfaces are
clean before assembling. Tighten the fuel line joints carefully and firmly, using two 12mm
wrenches, one on the furnace fuel fitting and one on the fuel line compression nut. For initial
installation, assemble & tighten fully, then loosen and re-tighten to assure an airtight seal.
If the unit is situated lower than the fuel surface in the tank, install a solenoid valve in the fuel line
close to the fuel tank.
Note the temperature of the exhaust while choosing the place for installing the through hull.
Any water entering the through hull is prevented from reaching the unit by using a gooseneck, a
drain lock or a sealable exhaust fitting.
Boats with a metal hull must isolate the unit and the through hull from the hull of the boat to
prevent galvanic corrosion.
Remember to read the instructions for installation, operation and service before installing the unit.
