Raypak pilot relighting for various models, including 106 and 156

SOURCE: Vulcan qasar gas wall heater.

If your hearter is an electronic model the solenoid has almost certainly failed.

SOURCE: why frequently relight my pilot?

check for water run off from above or sprinklers directed at heater. A high wind stack may be needed due to heater location. Millivolt models have a thermocouple or pilot generator that may be faulty or weak. Loose or rusty connections of the thermocouple to the gas valve or loose coil connection, or short in these wires can shut off a pilot.

SOURCE: I HAVE A RAYPAK VERSA, PILOT IS ON , BURNERS DONT COME ON

check mv output of thermopile ,unless you have 350-500mv it is not enoughvoltage to power valve

The main burner valve is the oven valve. The pilot will be next to the burner and you either have to insert a long shiskabob stick ( lit) into the hole or lift up on the bottom of the oven (inside) and you will see the pilot.

SOURCE: How do I relight the pilot light?

Hi,
There is no pilot light on many of the dryers of today. They light with a hot surface ignitor.
Here is a tip that I wrote about dryers and no heat on gas dryers...
