Gas log fire going out


Wasn't sure where to put this thread ............

We have just installed a Regency free standing Gas Log fire (natural gas)
Fan kicks in after 5 minutes or so.
Flame goes OK for awhile then cuts out.
Pilot is still going.
Then the flame will kick in again - after 10 to 20 minutes.

Is this normal?
Have never had anything to do with gas in the past so just being a bit cautious (and there is nothing in the manual about this happening)

Cheers

Sounds like it is cycling on a safety limit.

Yep and that could be dangerous and damage the unit. It may be overfired with the gas pressure from the valve set too high. Need a experienced Pro with a manometer to check and set it properly. Gas logs and fireplaces are strange ducks so you may want to call a fireplace co that services them.

OK, do you have a model number for the appliance? We need to know which model you are dealing with so we can better advise you.

Without seeing the manual a few things may be happening:

1. If the unit has a thermostat you may be cycling on and off on temperature so the flame coming on and off would then be normal operation.

2. If the unit is unvented it may be going on and off on the oxygen depletion sensor.

3. If the unit is vented (not direct vent) you may have a problem with the venting.

4. The unit may have a high limit that is weak.

Without more information, the above items are just guesses.

This is also possible however with decorative appliances such as gas fireplaces an overfire condition would be very obvious because you would get flame impingement all over the place. The flame would be way too high.

We need more information.

Yeah but how would a non Pro know that? Most homeowners are rather clueless, fire comes out and looks nice, Great.

not uncommon to see gas valves set at 4"WC instead of 3.5.

Had a similar issue on our gas log FTP. It was the safety switch that was on the bottom part that drops open. Some minor adjustment resolved it.

More than likely it would cause soot build up on the logs. But yes, you are right.

maybe the flames burn counter clockwise. the OP is in the Land of Oz and apparently the water drains counterclockwise.

needs a reverse flow log.

is this a vent-less unit? Is it in a closed off room? It could be a carbon monoxide sensor that trips. vent less units are suppose to have a window open a little for fresh air.
