Exhaust Connection
The exhaust is hot, keep a minimum of 5cm (2”) clearance
from any heat sensitive material. Failure to comply with this
warning could result in fire and serious injury.
A 30 mm flexible tube exhaust pipe with a length of 1M long is sup-
plied with the kit for the exhaust. An exhaust clamp is needed to
secure the exhaust to the the heater. The exhaust hose cannot be
any longer than 2 m. Connect the exhaust as follows:
• Connect the exhaust pipe to the exhaust port on the heater and
attach with clamp provided. Feed the exhaust pipe through the
silicone (white) grommet on the bottom of the box.
• Run exhaust to an open area to the rear or side of the vehicle so
that fumes can not build up and enter the passenger compart-
ment or the heater combustion air intake.
• Install exhaust pipe with a slight slope or drill a small hole in the
lowest point to allow water to run off. Any restriction in exhaust
will cause operational problems.
• Route the exhaust pipe from the heater using holders provided.
Caution: Run exhaust so that it cannot be plugged by dirt, water
or snow. Ensure the outlet does not face into the vehi-
cle slip stream.
Route exhaust beyond the skirt of the cab and outside of the
frame area. Route exhaust so that the exhaust fumes cannot
enter the passenger compartment. Failure to comply with this
warning could result in Asphyxiation.
Combustion air must be drawn in from the outside of vehicle.
The combustion air opening must be kept free at all times.
• Connect the air intake pipe to the intake port on the heater
and secure with clamp provided.
Caution: Do not install the intake opening facing the vehi-
cle slipstream. Ensure that the opening cannot
become clogged with dirt or snow and that any
water entering the intake can drain away.
