Thread: Who knows stuff about gas heaters?

After pulling it apart. I've discovered that if I can blow through if I hold the on/off valve in. Releasing it blocks the flow, is this working correctly?

If it does have a safety device, you may have to hold the knob pushed in until the safety gets hot enough. The usual type has a thermocouple that energises a small electromagnet under the relevant knob. If this is the case then there should be a small tube running from behind the valve assembly to an aforementioned element in the flame area.

Ian says it’s not lighting, only give a puff of flame....need to fix the flow first as the thermocouple won’t come into play until you have a flame with the button pushed in

What the heater connected to?

LPG or NG?

Any other gas appliances in the house?

The would be a test point to check pressure, somewhere near the inlet....you will need an instrument to check

Keep in mind gas is a licensed trade, for good reasons....I was trained as a gas fitted but let my license slip many years ago.

Hopefully it’s an indoor approved unit....

9kg bottled lpg. It will stay alight with the regulator held in.

Hi,
I have a similar problem on one burner on a 3 burner stove. I suspect it to be a saftey device problem.

Gas heaters can also have a safety device on the blower pressure I believe. Something like a barometer, won't let the gas burn if there is no air pressure from the blower fan.

N.B. I have no qualifications or experience on the subject.

Cheers

Ok, that men’s the thermo couple (safety device) isn’t energizing.

1. Thermocouple not siting in the pilot flame

2. Thermocouple is faulty

3. Valve/knob you push in is faulty.

Most times it’s the thermocouple not sitting in the flame.

Only the very tip is in the flame. I could raise it about 1_1.5 mm on the mounting screws.

Yep try raising it....
