Air pressure safety for glory hole

I've been trying to find a wiring diagram for an air pressure switch for gas to no avail. Can anyone help please.

While I can't give a diagram, consider a switch that has a sail on it that is the actuator. It's in line on the airline. When the blower is working , the sail is moved into the "on position " for the switch actuator. If it fails, the sail falls back and the circuit is broken. Make it part of your loop.

At least that's what I'd do. Ask Michael, he'll have something to say I'm sure.

Thatís strange. I thought I had responded but I guess I didnít hit the reply button.

Antunes makes a great air pressure switch. You wire it in series with a red hat normally closed gas solenoid. The Antunes should come with a diagram, but any good electrician will know what to do. Extra points if you also wire in an emergency cut off boiler switch next to your studio door.

I have this system, but the air sensor shuts off the entire gas system and not just the glory hole, but I have a gas furnace

I do know how the system works the problem was the switch has 3 points didn't have my glasses on so I didn't see them marked as common,normally closed and normally open.

The switch is set at 0.2 mbar should I increase it? The maximum is 0.5mbar.

Also it has 2 air inlets does it matter which one I use?

If they both pump air towards the burner at the same time, it shouldn't matter. If you can't turn down both air lines individually, , it should be a pain in the ass. If the switch doesn't respond to the lower setting, then by all means try the higher one. It's just a simple on off switch activated by pressure sideways.

Normally closed means that when you do not have air pressure, it will cut the circuit and your solenoid will turn off. Thatís what you want.

If you wired it for normally open, the opposite would happen.

I believe it does. I may be wrong but I think one is for pressure and one is for vacuum?

One pressure valve for pressure and one sucker valve - I doubt that could be ,
I think one is always open the other one alwys closed. But its pure guessing
Blowers dont suck in a pipe usually
