I know its a home unit, was trying to save some cash. Gas valves are very expensive up here in Canada. SodaJerk got his to work on 12vdc. Thought i might give it a try.
The RobertShaw 710-502 or 710-205 would be ideal. I'll work on finding one. Thanks for the advice Gdetrailer.
Sodajerk may have managed to get a 24V AC valve to "work" by playing around with the internals.. Not exactly a safe or good idea for folks to mess with.
Gas valves have several "stages", just because you hear a clunk, doesn't mean the valve has fully opened.. Valve must have full 24V AC to open both stages.. It IS A "SAFETY FEATURE" and messing with the internals may disable the purposely designed safety feature.
Natural gas is not something one should be experimenting with and propane by it's heavy nature can pool at the lowest point (IE floor level) and build up to the point of an explosion..
A millivolt gas valve setup for propane would be the best possible solution not to mention as safe as possible.
Pair that with a self powered digital T stat (one the has internal batteries) and you should be back in business (some digital T stats "steal" power from the 24V AC coming from the furnace and use rechargeable battery or capacitor power when the stat is calling for heat, those won't work for you).
Millivolt gas valves are still in use by gas fire place inserts so you should be able to find one that will work.
