NOTE: Should the particular application require more
than 14 feet of exhaust pipe, please contact the
Aqua-Hot Heating Systems Product Application
Department at 1-800-685-4298 for assistance.
Installing the Exhaust System:
The Aqua-Hot is supplied with a 3-inch and a 4-inch
black pipe nipple (1.5 inch diameter) along with a 1.5
inch exhaust elbow. Reference Figure 44. These
three exhaust system components
MUST BE uti-
lized with all product installations. Be sure to refer-
ence Figure 44 to determine which exhaust nipple
should be connected directly to the Aqua-
Hot’s ex-
haust port (i.e., the 3-inch or the 4-inch black pipe
nipple). Also, an exhaust tip is included that must
be installed on the end of the exhaust pipe in order
to remain in compliance with the testing agency.
Reference Figure 46.
1. Run the exhaust pipe to the driver’s side of the
vehicle and ensure that the exhaust fumes can-
not enter into the passenger compartment. Be
sure to keep the exhaust away from the slide-out
areas.
2.
Be sure to secure the end of the exhaust pipe to
the vehicle with the proper exhaust hanger/
support hardware.
3. Slide the exhaust tip (included in the shipping
kit) over the end of the exhaust pipe, being sure
to leave a required clearance of one inch be-
tween the band on the tip and the end of the
exhaust pipe. Mark where the holes should be
drilled to allow for a #8 sheet-metal screw 3/8
inch in length to securely mount the exhaust tip
to the exhaust pipe. Drill the holes in the pipe
and mount the exhaust tip. This will prevent
excessive air movement up the exhaust pipe pre-
venting the propane burner from extinguishing.
Reference Figure 46.
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.
•
Use standard 2.0 inch automotive-type exhaust
piping and avoid bends, if possible. Reference
Figure 42.
•
A maximum of three 90º exhaust pipe bends are
allowed.
• Do not use galvanized pipe or fittings; only black-iron
pipe and fittings should be used.
NOTE: Refer to “Internal Combustion Engine Exhausts
and Vehicle Wall Openings” in RVIA’s ANSI/
NFPA 1192 Handbook for the Recreational Vehi-
cle Standards, as well as the National Fire Protec-
tion Association’s (NFPA) 1192 Standard on Rec-
reational Vehicles for additional information.
CAUTION
All Aqua-Hot exhaust system installations MUST utilize the two
black pipe nipples and the black pipe elbow, which are provided
with the heating system, in the configuration best suited for the
particular recreational vehicle application. Failure to conform
could create a hazardous situation and will void the Aqua-
Hot’s
ETL product listing.
WARNING!
The Aqua- Hot’s exhaust is hot and must be kept away
from any heat-sensitive material.
DO NOT direct exhaust downward as a fire may re-
sult when parked in dry, grassy areas.
Exhaust must not terminate beneath the vehicle or
beneath an open able window or vent.
DO NOT terminate the exhaust pipe within the awn-
ing area of the motor home, if applicable. Be sure to
keep the exhaust away from the slide-out areas.
•
Exhaust should not exceed 14 feet.
