I have a peerless steam boiler that uses a 24v main gas valve. There is a 110 to 24v converter to feed the power to it. I recently lost power, just got it back 10 minutes ago actually, and was trying to come up with a way to run my system with the power out. Is the 24v dc? The valve says 24v 60hz 0.3A. I can't find a manufactures label on it to look it up. The 60hz made me think that it is 24vac, but I didn't really think that made much sense. Anyone have experience with these? Also, is it possible to convert that 24v valve to a millivolt valve? So that the system will run without power? There are no additional valves or other powered controls other than the Lwco (which is millivolt or 24dc), there is the high pressure cut as well, but those only cut power, not require power to operate.
