Re: Vanguard heater

Usually the pilot goes out because of a faulty flame sensor or wire connection.

Jim, it sounds like a gas pressure problem coming to the heater itself. Be sure the gas line shut off valve at or near the appliance is turned all the way ON. Also, check the air intake shutter on the burner to be sure it's not clogged. If it is, vacuum it out with a vacuum that has a hose and a crevice tool attachment.

One other thing to trouble shoot. Trace the wire from the thermocouple at the pilot, back to the control valve. It will be connected with a nut, Try loosening the nut with your fingers. If you can turn it, it's too loose. Finger tighten it and with the appropriately sized open end wrench, turn it only a quarter of a turn more.

Let me know how it works out for you.

I have a 3 brick Vanguard heater. The pilot will light, but when I turn the nob to light the heater, the light goes out.

if this is a vent free heater replace the pilot assy. this is the safety for the unit which controls the the gas valve also.

The part is ordered by Model number, a serial number is no help, and yes there is a part called the flame sensor that allows the gas to stay on, I am sure if you contact a local supplier they can provide a suitable substitute gas valve or sensor if it is a stand alone part, on most the sensor is part of the gas valve. I think you will end up having a local shop try and match up the valve.

Sounds like a weak thermocouple. With the extra heat of the main burner running it can keep the pilot solenoid open...without it it fails shut. Try replacing the thermocouple. (small rod the pilot flame burns against with a skinny copper tube going to gas valve).

How do you shut down

the pilot light always stays on, its designed to allow your heater to turn on by itself without you needing to light a match every time. if the pilot light is burning you have nothing to worry about. its when the pilot light goes out that a small amount of gas leaks into the room. and by small i mean smaller than a hand held lighter... if you still want to shut the entire thing down you could turn off the gas line feeding the heater or possibly the whole house, otherwise the pilot light will stay on. as far as the actual heater turning off, thats probably controlled by some sort of thermostat somewhere. if you set the temp to very cold it should stay off. if that doesn't work then you may need a new thermostat.

Burner keeps going out

It might be the ODS Pilot Assembly. It could be clogged with dust or lint.
It might be low gas pressure.
It could also be the pressure regulator.
