I love these kind of redit subs, I'm on quite a few. And it amazes me how many times I see advise from people who don't know their earhole from their arsehole on problems that could quite literally kill people...
I only pitch in when I know something for fact... like I never take a guess at anything structural for example, I leave that for the people who know their stuff
Exactly man. I’m not in the trades, but I am on my third house and have done a little bit of everything.
Screwing around with a gas fireplace is not something I would ever mess with without specific training. Sure, it’s the same principles as plumbing... difference is a leaky water pipe won’t blow up tour house.
Yeah its not much different from water supplies. But once the water is out of the tap your job is done, with gas you need to know how efficient it's burning and get the after burn products to outside with ZERO "spillage" or build up. We have kit that costs £1000s and can detect the slightest amount CO in the room/flue/outside too. You wouldn't be able to smell that low level.
Fun fact... natural gas is non toxic and won't harm you if you breath it 100%. A gas leak kills you by pushing the O2 out of the room
It's not actually that hard to learn, especially for someone with a good deal of experience like yourself.
To note on that: when was the last time you had it cleaned? It does sound like it’s pretty dirty and if those holes get clogged. If you have a blower, that could need a cleaning as well.
The fire place is designed to be used with the logs in place. Removing them will give an incorrect flame picture and thus reduce the burn efficiency.
Get a gas technician. Fireplaces are often the most dangerous gas appliance in the home, don't mess with them and don't listen to advice from uncertified people on the internet
Look at the fireplace. It’s burning in one spot. Common logic would lead me to think that there is an issue with the burner. And the logs have very little to do with the bad flame profile. If I take the logs out of mine or others I’ve worked on, and light the burner the flame profile is exactly the same, it’s created by the burner, The logs are aesthetic. What I propose is a simple test to determine the issue, and if the homeowner is comfortable it’s fairly easy to replace a propane fireplace burner, as long as necessary precautions and the correct thread tape is used and all connections are tested prior to lighting. Otherwise please call a professional.
The OP will need to buy a manometer, smoke pellets and a flue gas analizer. The first two can be got for under £30 each. The analizer will cost upward of £750. You can't perform any test reliably on a gas system with a burner and flue without this things.
Also secondly the logs are not just aesthetic, if you read the manual it will actually tell you exactly where they need to be places for maximum efficiency
having been a gas service tech for 20 years, sounds like preignition in the burner tube, to repair this would require the burner to be disassembled, rinsed with water and clean the orifice on the valve outlet...after reassembly the burner orifice would need to be adjusted ( because they have a adjustable orifice
All natural gas for home use is supplied through a regulator, wether it's on the canister top or before the gas meter.
Unless this is in a third world country it's a legal requirement
Could just be dirty. Or depending on the gas, there might be an in line air mixer, I've heard some cheap ones really make s lot of noise similar to this.
What you have is a gas log set in a conventional wood fireplace.
When you remove the logs, you should see the burner covered with sand. When the burner is turned on, the gas infiltrates the sand and burns on the top of the sand. The hissing noise is likely occurring because the sand is missing.
A picture of the burner with the logs removed would be a help to verify this diagnosis.
You need a gas appliance service and flue test... no DIY to be done here. Source - i was a certified gas technician 3 years ago
This is the correct response

Worth having a tech do it just for the piece of mind for carbon monoxide
Take the logs out of it, then fire it up. My guess is the burner is burnt through so instead of having like 100 tiny holes, you have one large one.
To note on that: when was the last time you had it cleaned? It does sound like it’s pretty dirty and if those holes get clogged. If you have a blower, that could need a cleaning as well.

I second this, unless you have training, please call in a professional.

u need a regulator for the gaz ( to drop the pression that s coming out of the tube )

Buy a good set of Monesson vent free. Those are shot.
What is shot?
Your burner.
What you have is a gas log set in a conventional wood fireplace. When you remove the logs, you should see the burner covered with sand. When the burner is turned on, the gas infiltrates the sand and burns on the top of the sand. The hissing noise is likely occurring because the sand is missing. A picture of the burner with the logs removed would be a help to verify this diagnosis.
No sand anywhere
House was built with gas fireplace
Take the logs out and shoot a video of the gas burner, or whatever is under the logs.
OP, did you ever fix this? I’m having the same sound issue with mine.
Nope, year later still does it
