Installing your Heater
Vents
Engine compartments are vented to supply fresh air for your engine, and to allow
fumes to escape. During the winter, the vents also allow heat to escape. As heat
rises, a “chimney effect” can literally begin to suck the warm air out of your bilge,
reducing the effectiveness of your Xtreme Heater. Cover or plug your vents during
periods that the heater will be working, and be sure to uncover your vents and run
your blowers before operating the boat!
Mounting
If you are mounting your Xtreme Heater permanently in the engine compartment,
consider the location and material that you are mounting too. If your heater is
being mounted upright, on a flat surface, the included self-tapping screws will
work fine to secure the heater in place. If the surface is wood, be sure to seal the
holes with a bit of caulk to keep water out. If mounting your heater horizontally,
or upside-down, consider through-bolting the heater to the surface, using fender
washers for additional support and nylon lock nuts to prevent loosening from
vibration. Again, if the mounting surface is wood, seal the holes to prevent
moisture intrusion.
Wiring
If you wish to wire your heater permanently into the boats electrical system, the
power cord on the Xtreme Heater was chosen based ABYC requirements for engine
space wiring and is suitable for permanent wiring to a spare breaker on your boats
110v panel. The 20’ cord should reach most panels without splicing of additional
wire into the circuit. We strongly suggest your Xtreme Heater be installed on a
dedicated circuit with its own breaker. If you are installing two heaters, we suggest
each be installed on a separate breaker. Check the breaker requirement for the
heater(s) you have selected to be sure the circuit breaker(s) are of adequate capacity.
Wiring should be routed away from moving parts such as belts and pulleys in the
engine space. Wiring should be secured and protected from chafing on sharp
edges along the run.
CAUTION: We strongly recommend a qualified marine electrician
be contracted to permanently wire your heater(s) into your boats
electrical system, following ABYC Specifications. If you choose to
perform your own electrical work, make sure the boat is disconnected
from shore power and your generator is off.
