Propane heater troubleshooting?

[mbulriss]

Steve,

Those rocker switches on your PT sound like the hydronic heating
system (or engine bypass heating) for when the Detroit is running.
You probably have a set of those switches under the dinette and in the
bedroom also since they are usually zoned into 3 heat exchangers. The
on/off is obvious; the hi/low is for the fan speed. Going from
memory, for this system to work properly, you need the water gate
valves coming off the engine opened, the "chassis heat" thermostat
turned on and set to a desired temp, the summer/winter switch on the
dash set to winter, and the "aux pump"(?) switch on the dash on. At
least that's the way I recall it is in my 83 PT40. Don't use that
system much in South Texas, but it is real effective when going down
the road.

Those two rocker switches should have nothing to do with the propane
heating system which is totally separate. For the propane system, you
need the propane tank valve open, the propane line valve near the
heater open, the gas master/sensor on (usually under the dinette), the
thermostat on the wall set to heat and a high enough temp selected to
turn on the heater. All of this is from memory, but seems correct at
the moment.

Good luck.
