Atwood camper heater>>> repaired with pictures page 2

Ordered Dinosaur Electronics (FAN 50 PLUS PINS) Ignitor Board
$94 with free shipping on my amazon membership.
It says it is convertible to WH or refrigerator board and has upgraded circuit for turning the fan off with no ignition.
Should be here on Sunday.
Anything else worth checking?
I removed more panels around the furnace and looks to me like it is design to warm up the park more than the camper.
The lower part of furnace circulate cold air inside. No insulation. I tried to put some insulation there, but is build into cabinet so not much space. '
One of the ducts goes to tanks compartment, where via holes around the plumbing goes outside without restriction. I bought gate valve for that ducts, but gate is 2" while duct seems to be 1 7/8"
Will post update when new board arrives.

The new board was delivered on Sunday (!)
Have it installed and turn out that original 2004 is consider "old" board and had to call technician for help in rewiring the jumpers.
All fired up and is good.
For 2" gate valve installation, I found 2" pipe I used for central vacuum and cut short pieces of it. Glue small nipples inside the gate with Gorilla glue, that expands while it sets, so it filled up small gaps and the camper ducts slide easy on it.
All is good now. Waiting for rain season to pass.
El Ninjo sucks.

My 8520 is totally dead, I purchased a new one and I was sent the new AFM model and guess what it is not the same size, the exhaust is off 1/4 inch and to top it all off it now has a top loading propane connection.

The Real 8520 is no more, just found on of the last units in the USA.

I guess Atwood was taken over by domotec and their lame engineers made these changes, so beware if you get sent the AFM model it is not the same as the 8520.
