Re: duo-therm 65920 heater
What do you mean by "the gas won't turn on"? Do you mean the burner won't startt, or it won't stay lit, or it tries to light but there is no gas there at all?
If there is no gas at the heater, try lighting the stove. If it lights and burns steadily, the overall gas system should be ok, and I'm out of my depth. Based on what is actually happening, probably someone out there can give you good advice, but they need more data to do so.
