Hi All
I have a home gas central heating unit mounted on the outside
wall of my garage and blowing/sucking through a couple of grills in
the garage wall. Nice, it has worked well for the last 10 years to
heat the 10,000 square foot garage.
Sadly it recently died and tried to cremate itself but only succeeded
in burning some of the wiring.
No problem I thought, I just replace the cremated wires clean the
burner and away it goes again.
Wrong!
To cut a long story short I have no 24V to run the solenoid on the gas
modulating valve, chasing the wires back there is a transformer and
some printed circuit boards so I think the burnt wires shorted and
fried the solid state thingo.
Problem is it's old heater, no parts or etc available for it.
So I need a generic wiring diagram if anybody know where one can be
got off the web.
Is the 24V AC or DC? The gas modulating valve has several electrical
terminals on it but I think it only needs the wires to the actual
solenoid, am I right?
Thanks in Advance

Am I missing something here? 10,000 square foot with a couple of grills.
That's big enough to have its own microclimate!
