Hot Water Heater

We have a 2004 Sunline 2475 with an Atwood(GC6AA-9E) water heater. It seems to be running okay and gives us plenty of hot water when using it on electric and propane. However, when we are running it on propane black smoke is coming out of the flue box assembly area and discoloring the outer hot water heater compartment. When running it on electric, we don't have this problem. Any suggestions as to why this is happening?

Jim-Bev-2363 is an unknown quantity at this point
I would say you need to have the LP side serviced. Cleaning and adjusting of the flame is in order. Improper air and gas mixture of the flame will make smoke.

JohnB is on a distinguished road
Here is an expert out of the Atwood manual

ERRATIC BURNER FLAME OR SOOTING
Low gas pressure ------------------------------------------------Set inlet pressure at a minimum 11˝ W.C. with two or more gas appliances running Poor gas supply --------------------------------------------------Replace gas supply
Improper air adjustment ----------------------------------------Adjust main burner air shutter approximately 1/4 way open. Flame
should be mainly blue and quiet.
Poor main burner alignment ------------------------------------Adjust valve and main burner alignment
Misaligned burner flame spreader ------------------------------Align flame spreader so it is square with end of burner tube.
Blocked burner orifice --------------------------------------------Clean orifice. DO NOT enlarge orifice
Obstructed main burner------------------------------------------Clean main burner
Obstructed “U” tube ----------------------------------------------Clean “U” tube
Obstructed exhaust grille ----------------------------------------Remove obstruction


If it is the air shutter, here is the guide
5. CHECK THE AIR ADJUSTMENT.
The burner tube has an adjustable air shutter on it at the end where it goes over the orifice. Position the air shutter so that it is 1/4 of the way open. We are looking for a blue flame with small traces of yellow in the flame. If the flame is fairly quiet then it is adjusted correctly.

Odds are good it is the air shutter is choked too much. The flame spreader may do it but believe the shutter may be more the issue. And for sure make sure the heat tube (U tube) is clear and does not have any insect nests inside it. You would have to pull the burner off and run a wire brush or rod through the tube. Compressed air helps too.


Here is the rest of the checks in this area.


Hope this helps
