Exhaust System
Exhaust System Requirements
Introduction:
The Aqua-Hot’s exhaust is hot and must be kept away from any
heat-sensitive material. Therefore, the exhaust system should
be checked to ensure that it continues to meet the following
requirements.
•
The exhaust must not be directed downward as a fire
could result when parked in dry, grassy areas.
• The exhaust must not terminate underneath the vehicle,
underneath an openable window or vent, in the awning
area of the RV (if applicable), or near the slide-out areas.
• The exhaust must be able to freely exit away from the
vehicle without any obstructions.
• Use standard two-inch automotive-type exhaust piping
and avoid bends if possible.
• The 3-inch and 4-inch black pipe nipple and the exhaust
elbow, originally supplied with the Aqua-Hot must be
used (kit sold separately).
• Mounting must be place every three feet to adequately
support the exhaust system.
• Total exhaust system length must not exceed 30ft in total
length, and shall contain no more than two 90° bends.
