I use a wood boiler that is piped together with an oil boiler to heat my house. Both units are inside my house side by side. I want to re-plumb and re- wire the two boilers. I feel I have the plumbing figured out, might have an extra valve or two. It's the electrical that I have a question with.
If there is anyone who is willing to share their burner gun skills and knowledge here is the explanation of what I want to do and the question. I want to use the controls on the oil boiler to run the zone valves and the one circulating pump for the entire system. I want the option of having the gun fire to keep the house warm when the wood burns out or just let the house cool down some and I get a fire going in the morning and get the house back up to temperature. To prevent the gun from firing when I don't want it to I have drawn a switch between the boiler controls and the burner gun.
The question. Will the controls that supply power to the circulating pump and zone valves still work? My thoughts are the cad cell that is down in the flame area will not see a flame and after the 10 second or so time period shut power off to the whole system. The cad cell wires attach to the F F terminals in the control box. My thought is to wire up a switch between the F F terminals and close the switch when I fire with wood or leave the switch open when I just want to fire with the oil. Will my wiring idea work? Or is this post as clear as mud. Or is there a better way to wire this up?
