Duo therm heater question

[cweiss87]

Maybe someone here can help me out. I bought a older terry taurus bumper pull trailer for a great deal. Well the heater in it is a duo therm 66017-007 and the thermocouple was missing. I found a parts sheet online and was able to buy a new thermocouple but I can't figure where it hooks to the gas valve at. If anyone knows or has a similar heater with a picture it would help me out alot. I can't find a manual for this thing anywhere. Thanks in advance.

I guess you mean furnace? I thought the DuoTherm line was AC/heat pumps, roof mounted. This is a floor mounted gas furnace?

It's for a trailer furnace

see if this helps ? http://bryantrv.com/docs2/docs/operating/dt6600.pdf

Ya its a direct vent wall heater. Duo therm was the big maker of them back in the day.
And zmann thanks for the info but thats the same one I found but it bein direct spark ignition it doesnt say anything about a thermocouple.

Dometic is the manufacturer. Duo Therm is the model name.
The thermocouple may be in the same piece as the ignitor, idk.

It will have to go directly in front of the pilot flame. The thermocouple heats up and makes voltage to hold the pilot valve in the gas valve open.

I know, both the thermocouple and ignitor have to go right next to the burner. But idk if they are sold as one piece with one wire or not. New ones are, I'm guessing this one won't be.

Post a picture if you can.

Have you tried getting the model and serial numbers off of it and asking a camper supply house if they have any info?

The brand is duo therm. Model 66017-007. I have tried a couple dealers around here that have good service centers but they dont know. I already have the new part and know where one end goes its the gas valve side I'm not sure of.

This is what I have for pictures for now.
