It appears that the "temperature" knob is just a valve. Does the furnace have a lower flame when the "temperature" knob is set at Low?
No. The Temp dial turns heater on when turned up (you hear a noticeable click) then the burner kicks on. There is no middle ground, it's on, or it's off.
That really doesn't answer the question of the flame height. I understand that it increases the delivery from the valve so that the main flame ignites. I just wondered if you've ever looked at the flame to assess if the temp knob can control the flame intensity. I'd bet dollars to doughnuts that it does.
Here's a scenario: Even with the temp knob turned down to a lower position, the furnace may give off enough heat to warm the cabin and keep warming to too high an interior temp. This would be especially true with a mislocated or malfunctioning sensing tube. If the temp knob can be rotated so the main flame goes off and the furnace idles on pilot, the furnace may keep the interior comfortable for a long time.
You may be correct. And, I'm not trying to start a argument or anything. Besides, I can't afford to bet dollars, maybe doughnuts.
I had a RV furnace similar to this one once. There was no flame adjustment. It just clicked on and off. There was quite a bit of swing in temps between on and off though.
The temp adjustment didn't do a heck of a lot. It just made it turn on a little bit sooner.
The OP's furnace may be different but, someone told me mine was called a "Gravity Feed" what ever that means.
I sure loved it. It required no electricity at all. I wish they still made them.
1. No, the flame height does not change when turning the dial further beyond the on/off point.
2. Yes, it's a Gravity feed furnace, love it for its simplicity, just the thermostat issue.
3. No forced air on this one, however, it was available on some units, where the 12v fan would turn on either automatically with the burner, or you could run it manually. That'd be a good setup, where you could use the fan when plugged in for better heat distribution/circulation, and cancel it when in the boonies.
