Common questions

Will gas leak if pilot light is off?

Will gas leak if pilot light is off?

If the pilot light goes out on a storage or instantaneous hot water heater, space heater or a ducted heater, you will not have a gas leak. This is because all modern gas appliances with pilot lights have a fail-safe device that closes off the gas to the appliance in the case when the pilot may go out.

Is it OK to leave pilot light off?

Generally speaking, it is safe to leave your continuous pilot light on at all times, assuming it stays lit (more on this in a moment). While it does cost more to keep your pilot light on in between uses, it can actually have some benefits to your system.

Is it bad if your pilot light goes out?

The pilot light is a small, blue flame that is used to ignite the natural gas being pumped into the main burner. This tube is fitted with a safety valve (the thermocouple), which stops the flow of gas if the pilot light goes out. This prevents gas from building up in your furnace, posing a safety hazard.

What to do when your gas fireplace wont stay lit?

Go to the valve and spot the contacts that are labeled TH and TP/TH. Take a wire and connect TH and TP/TH directly. By doing this you are bypassing all the safety switches and fuse to see if the problem is in between the valve and the wall switch. If your fireplace goes on then the problem lies within the current path.

What happens if there is no pilot or main gas?

There was no pilot safety control, and if the pilot went out, the main gas would still turn on when there was a call for heat. I guess you can see the problem here: no pilot, main gas, big boom. This did lead to explosions, fires, and lots of burned hair and eyebrows.

What to do if gas is present at the gas valve?

Remove the pilot tube at the gas valve and depress the button. If gas is present at the gas valve and not at the pilot, check the pilot tube and pilot assembly orifice for blockages; clean or replace as necessary. The pilot stays lit. Check the thermocouple for lint or pet hair; clean if necessary.

What to do if the standing pilot light is out?

You look at the boiler and find that the pilot light is out. The heating unit (boiler or furnace) has a standing pilot with a thermocouple. The first step is to make sure there is gas. Shut the gas cock at the appliance and open a union or drip cap. Turn on the gas cock. If there is gas, shut the gas cock and retighten the gas union or drip cap.

When to turn off gas at the meter?

Turning off the main gas shut-off at the meter ensures that there isn’t any more gas being fed into the house at all; it should be your option whenever you can’t tell what appliance is the source of the leak or can’t find a local shutoff valve.

What should I do if I turn off my natural gas?

CAUTION: If you turn off your natural gas at the meter, leave it off. Do not turn it back on yourself. Contact us to turn the meter back on and relight the pilots. For safety, a shut-off valve should be installed at every natural gas appliance.

What does it mean when Gas Stops coming into your house?

If you hear a small click and/or the flow stopping during this, it is the excess flow valve shutting off again – repeat the procedure from the start, but do not open the valve quite so much the next time. When the flow stops, indicating that the gas has fully pressurised the system, slowly open the service valve fully.

How do you know if there is no gas coming from your gas line?

To check and reset it: Turn off all gas appliances. Turn the service valve off and wait 15 seconds. Open the valve one sixth of a turn – you should hear gas flowing through the system. When the flow stops, indicating that the gas has fully pressurised the system, slowly open the service valve fully.
