Question about Heaters
I have a Comfort Glow Vent-free Gas Heater model number CGN18B. The pilot light will come on when i set the dial to "pilot". However when i turn it "high" the pilot light will go off. Any ideas?
Check with Ebay seller s.a.w.inc for available thermocouples. If that doesn't solve the problem the valve unit will likely need replaced.

The pilot light is operated off a millivolt generator. that is the small tube directly in the pilot flame. its purpose is to generate a small dc current which is connected to the pilot valve inside the main valve. setting the control to pilot opens just the pilot gas supply. when operating normally the millivolt generator keeps a small electromagnet pulled in that keeps the pilot gas supply open. if it don't work the pilot gas supply valve closes. replace the thermocouple.
