AFFECTED:
On motorhomes affected by this Product Upgrade, an older revision of the
rear pipe section of the Aqua-Hot exhaust may have been installed during
production, resulting in a configuration that will make the Aqua-Hot exhaust
pipe exit the rear of the coach, below the trailer hitch skid guard. This could
cause the exhaust pipe’s chrome tip to become damaged from scraping if the
vehicle is driven on an incline.

INSPECTION:
4.
Locate the Aqua-Hot exhaust where it exits at the rear of the motorhome. Kneeling down,
observe the area at eye level to evaluate the vertical relationship between the Aqua-Hot
exhaust pipe and the trailer hitch skid guard.
PHOTO REQUIREMENT: Take several clear photos while at eye level with both
components.
Compare your findings to Figures 1 and 2 to determine whether the installation is
correct:
a) If the Aqua-Hot exhaust is located higher than the skid guard, the installation is correct
and no further work is required. Attach photos to a draft claim in A.D.N. and submit as
“Inspected/Not Defective” using the repair code on Page 5.
b) If the Aqua-Hot exhaust is located lower than the skid guard, it will need to be
replaced. Continue to the REPAIR PROCEDURE beginning at Step 5 on Page 3.

REPAIR PROCEDURE
5. To begin removal of the rear pipe section of the
Aqua-Hot exhaust, remove the 2 ¼” exhaust
clamp, located near the forward edge of the
radiator. Set the clamp and its fasteners aside
for later reinstallation. See Figures 4 and 5.
Figure 6
Figure 4
Figure 5
6.
Remove the Aqua-Hot exhaust pipe’s clamp
fasteners from the hanger bracket, installed
near the exhaust outlet. Set the clamp and
its fasteners aside for later reinstallation. See
Figure 6.
7. Remove the chrome tip from the exhaust pipe
and then disconnect the rear section of pipe
from the rest of the Aqua-Hot exhaust system.
Discard the rear section of pipe as it will not be
required for the repair.
Inspect the chrome tip for abrasions or other
damage; if damaged, order a replacement for
the repair. If no damage is found, set the tip
aside for future reinstallation. See the Parts list
on Page 5 for all replacement part numbers.

8.
Locate and remove the rear hanger bracket
by removing its upper fasteners. These are
typically located on the side of the trailer hitch
frame. See Figure 7. Set aside the hanger for
future reinstallation.
9.
Begin installing the replacement Aqua-Hot
exhaust pipe section by sliding its flared end
over the Aqua-Hot exhaust pipe still remaining
on the coach. Do not clamp this connection
yet; it will be done in a later step.
10. At the rear of the coach, rotate the newly
installed exhaust pipe section so that it exits
the coach above the trailer hitch skid guard
and has clearance with any other nearby
components (e.g., rock guard, rock guard
mounting chains, etc.).
Figure 7
11. With the rear section of exhaust pipe properly
oriented, use a 2 ¼” exhaust clamp to secure
the connection between the two pipe sections
located at the front edge of the radiator. See
Figure 8.
Existing Aqua-Hot
Exhaust Pipe
12. Moving to the rear of the coach, loosely attach
the exhaust pipe hanger to the new section of
pipe using a 2 ¼” exhaust clamp. Do not fully
tighten the connection at this time.
13. Adjust the exhaust pipe hanger into position
so that it can be attached to the chassis in a
manner that supports the exhaust pipe above
the trailer hitch skid guard. After attaching the
hanger, tighten the exhaust clamp.

14. Install the chrome exhaust tip to complete the
repair.
PHOTO REQUIREMENT: Take several
clear photos of the new installation while at
eye level with both the exhaust pipe and the
trailer hitch skid guard. Attach the photos
to the draft claim in A.D.N and submit using
the “Inspected/Defective/Repaired” flat rate
code on Page 5.
