Propane Heater Removal

[Ralph L. Fullenwider]

Wendel:

Lets do a re think on how the heaters are removed. First of all, the heater
core comes out of the outer shell, in place. Put the 2 front screws back
into the outer shell attaching it to the floor. There are three of these
screws that hold the heater in place, the front two you have found and the
3rd is in the back of the outer shell and is removed after the insides are
pulled out.

Ok, you have the Lp line disconnected and the brass elbow going to the
unit removed, now remove the 5 control wires if hard wired or un plug the
connection if there is a plug. Suggestion? on a pad of paper, draw a
diagram of how your unit is wired, do not try to remember them, it won't
work, been there done that. Now then your ready to locate the 5 screws that
hold the inside of the unit to the out case. they are usually 1/4 inch
square head sheet metal screws. 4 of them will be pretty easy to find but
the 5th is harder, it is semi hidden back on the right side about 1/2 way
down and back deep, you will need an extension to get it out.

Re cap, LP line is disconnected, LP elbow is removed, wiring is un wired
and 5 screws are removed. now the unit is ready to slip out of the outer
casing. The screws you see from the out side intake and exhaust tubes are
not part of what you need. Now then those tubes from the burner plenum are
slipped into the compression rings of the outer tubes and may be rusted you
just have to use a little persuasion to move them.

Caution!!!!! This is a MUST remember and check. Those tubes MUST me slipped
back in when re assembling and they MUST slip into the outer tube a MINIMUM
of 2 1/4 inches. This keeps the CO2 out of your Coach. If the out side
tubes are rusted, replace them, no guess work, replace them.

You need a manual on Suburban heaters. Good luck
