Problem heater

[MIKE IN lINO III]

I have an older Holiday Rambler with a Suburban brand gas heater, the problem I'm having with the heater is; it won't stay on. The exhaust is real sooty, the manual says that it is not getting enouph fresh air. I have checked and everything seems to look OK. Is it possibly the thermo coupler??

I'm going up this weekend and it would be nice to have some heat. I'v also noticed the water seperater by the propane tanks has some water in it but I can't figure out how to get it off.

Any advise would be appreciated,

Mike

What does the flame look like when you start it?? The thermo coupler might keep the flame going, Is there a power vent on this unit?? Is there any adjustment for the burner?? Check the regulator, maybe sticking??
