Section 3, Installing the Exhaust System
3-2 The POLAR™ HD Heating Module
• In a vehicle, the typical mounting location for the exhaust
outlet is under the floor of the POLAR™ HD Heating Module
compartment, or on the other side of the vehicle, directly
across from the module. Keep in mind you cannot exceed 12’
of exhaust piping, without any bends, or 8’ with two 90°, 2”
minimum radius bends.
• Position the outlet of the exhaust pipe so that the exhaust
exits off the side of the vehicle, not directly underneath the
coach or under an opening window, vent or slide-out.
Recommendations for Installation
The following applies:
• You may use sweep bends but each 90° bend is equivalent to
two foot of exhaust piping. For example, if you use two 90°
bends you must deduct two foot per bend from the maximum
allowed 12’ straight exhaust pipe length. Therefore you will
be restricted to 8’ of straight exhaust piping plus the two
bends. Do not exceed these recommendations.
• The combustion air must be drawn from outside the vehicle.
The maximum length of the air-intake tubing is 7 feet. Do not
exceed this recommendation.
