I have a Raypak 130a. The pilot lights but the burner won't fire. The manual states to Jump across both TH wires on the gas valve as the first check. If Burner doesn't fire, replace gas valve.
As soon as I jump the TH, the pilot goes out. The troubleshooting is unclear if this should happen.
Is this expected or am I doing something wrong?
Does this confirm a bad Gas Valve?
