3.2 Mounting Location
If all technical specifications for mounting the exhaust
cannot be met, don't use the
heater may perform poorly or be damaged if it is not
installed according to specifications.
Recommended Exhaust Outlet Locations
The following are recommended for exhaust outlet locations:
· Mount the
compartment. Be aware that exhaust fumes could infiltrate
the vehicle if the exhaust is not vented correctly.
· In a typical vehicle installation the exhaust runs from the
bottom of the heater, through the floor and exits from either
side of the vehicle. Excluding the 90° bend from the heater
and without any additional 90° bends, the exhaust run cannot
exceed 12'. A 90° bend within the exhaust run reduces the
total allowable exhaust length by 2 feet. For example, if after
the 90° bend exiting the heater, the exhaust run includes one
90° bend, the total exhaust run cannot be longer than 10
feet.
· The outlet of the exhaust pipe must be located so the exhaust
exits directly out from under the vehicle and does not
accumulate under the vehicle. Exhaust outlets cannot be
located under an opening window, inlet vent or a slide-out.
Recommendations for Installation
· Combustion air must be drawn directly from outside the
vehicle using the supplied air intake hose. An (optional) air
intake silencer can be used (ITR part # 10455) see figure 3.1
· If an exhaust muffler is required, use an ITR-manufactured
muffler (part # 10282) with a straight-through design. No
other muffler is acceptable.
The exhaust and outlet are HOT and the surrounding areas
must be thermally shielded and protected from hot
surfaces and heat build-up. Nothing can come into contact
with any part of the exhaust system.
· Install an exhaust collar into the floor of the vehicle to isolate
the hot exhaust fittings, attached to the heater, from the
vehicle floor. (ITR part # 5164) Various exhaust collars are
available to accommodate different floor thicknesses.
