Have you looked inside the boiler, down by the burners?


Sorry, couldn't resist...



Seriously though, I doubt you'll find an exact replacement, but I'm sure you can find something that can be retro-fit.

Can you see any numbers on the gas valve itself?

What leads you to believe that the gas valve is bad? What are the symptoms?

Rona,
V800A-1070 Honeywell gas valve. Pulled this off an old thread from someone who had the same boiler as yours.
Go to pex supply for the particulars.
Hope this helps.

This was used as a replacement GV on an American Standard G25.
This is also a 24v gas valve. Make sure you don't have a power pile system, which is different.

Good Luck,

Hi Ron,

There are two basic types of gas valves:

MILLIVOLT

24 VOLT

The MILLIVOLT valve is 'powered' by a 'ThermoPile' which is similar to a 'ThermoCouple' but has a much higher output voltage. This type of valve does NOT need an external power supply to operate. There will be two wires going to it, but these wires do not supply power, only a 'switch' closure from the boiler control.

The 24 VOLT valve DOES require external power and the Thermocouple is only used to prove that there is a pilot flame lit before allowing the valve to open. The two wires from the boiler control carry 24VAC to the valve and are 'usually' marked as TH and TR .

I can't find any reference to a gas valve with those numbers.

It might help if you could take clear pictures and post them.
