Exhaust System Requirements:
The exhaust must be able to freely exit away from the
vehicle without any obstructions.
Angle the exhaust pipe towards the rear of the vehicle
so that the exhaust fumes will naturally move away
while the vehicle is in motion. Reference Figure 40.
Use standard 2 inch automotive-type exhaust piping
and avoid bends, if possible. Reference Figure 39.
A maximum of two 90º exhaust pipe bends are al-
lowed. Reference Figure 39.
Do not use galvanized pipe or fittings; only black-iron
pipe and fittings should be used.
The total length of exhaust pipe should not exceed 20
feet.
The Aqua-Hot is supplied with a 3 inch and a 4 inch
black pipe nipple (1½ inch diameter) along with a 1½
inch exhaust elbow. Reference Figure 39. These three
exhaust system components
MUST BE
utilized with
all product installations. Be sure to reference Figure 41
to determine which exhaust nipple should be connected
directly to the Aqua-Hot’s exhaust port (i.e., the 3 inch
or the 4 inch black pipe nipple).
NOTE:
Should the particular application require more than
20 feet of exhaust pipe, please contact the Aqua-Hot
Heating Systems Product Application Department at
1-800-685-4298 for assistance.
