Hi Rich,
Thanks for your reply. The guy that sold me the heaters(2)bought them from somebody else while I was on vacation (6 years ago)on the assumption that I would want them. They simply had them mounted high in the shop with pilot light constantly lit. The put an on/off switch on the wall in line with a thermostat. The switch would cut in/out the 24 volt transformer needed for the gas solenoid (and I suppose the thermostat).

Thanks for your thoughts.
