Galvanized steel around stove

P-J-D_2

Hi guys had a question..

Had stove installed its great but, bit of an odour when it gets to temp..

Fairly sure it's not the paint curing - stove has been installed for a month and I locate source of smell at underside of lintel, picture here with the brown spots (which I suspect are burn marks)..



As I understand it the lintel was sandwiched between brickwork previously and was repurposed for the job. It looks painted or it's some sort of off white/grey coating.

What I'm wondering is whether it would be a safe solution to paint over the offending material with heat resistant paint, such that its encapsulated - would that contain any poisonous gases or could they still permeate? Should the coating be sanded off?? Should it be boxed off? What is the best way of approaching this?

I'm also concerned it may be galvanized steel - which I understand will off gas at temperature which is dangerous to health? Is there a way to tell if this steel is galvanized.

I'm not expecting to do this stuff myself I should imagine the builder will make good..

That just looks like surface rust to me, harmless.

Just how hot is that area getting?
If you can keep your hand on it for a couple of mins after the stove has been on for a while there's no way it's burning and it'll be safe to paint with hammerite or similar. If it's too hot to touch then get some exhaust paint from Halfrauds and use that....

As above. It's just surface rust and nothing to worry about. If it was galvanised, it would only start giving off harmful vapour at 907°C.

It doesn't get stupidly hot, but it stunk so horrible at lower operating temps was probably getting a bit para...

Good to know it can just be painted... thanks chaps

Whats the black gunky looking sealant ????
Are you sure the fumes/smell are not coming from that ???

Not sure what the black sealant is. Did wonder myself and tried pulling a bit off and burning with a lighter but didn't have the same stink.

My nose points to the spotty lintel..

That said I do find it pretty hard to pinpoint smells. My nose is pretty sensitive but isn't that accurate when it comes to locating things, especially when it involves inhaling "hot chemical vapours" from a stove... something about that activity makes me want to do as little of it as possible..

Also, if you picture it the heat collects around the stove and gushes forth past the lintel as it rises into the room. Pretty hard to isolate smells from a stream of hot air like that.. but I think I can say the stove itself is not responsible..

I guess that lintel will get painted, and if the smell continues.. move onto the next possibility.

Looks like rust on lintel which can soon be fixed. Is that grey thing your registry plate? Odd the black sealant stuff though mine is complete metal painted black. I used stove paint its attached to chimney with screws


My stove did stink a little when new that was years ago

This install has a fireboard instead of a metal register plate. The chimney has a flexible liner installed (house built in 1770 - needed it) stove connects directly to the liner so no need for a register plate. The stove and liner are thus operate as "a unit" the fireboard merely closes off the chimney space and prevents debris from falling in.

Here's a couple of pics.

I notice you've got one of those eco fans savemoney.. how do you like it ? Worthwhile investment ?

Ours has stainless steel liner too.

Regards to eco fan I still reserve judgement this year will be its 3rd season, I would like to think it does help but whether that's the pasebo (unsure of spelling) effect I dont know. I does get very hot in dining room where stove is and cooler further away. Can't stay stove heats whole 3 bedroom semi up just takes edge off certainly keeps downstairs warm though

Make sure you get stove swept every year and get a carbon monoxide alarm I think its law now. I also had to have a vent fitted to outside wall.I have had my stove over 5 years now

PJD you should still have used a metal reg plate, if a piece of debris like 1/2 a brick falls it will go through your fibre board plate, if its been backfilled with vermiculite this is unlikely to happen but then you could have the back fill drop if the fibreboard breaks which is possible.

If that black sealant has been used to seal off the flue pipe through the reg plate then that maybe your smell, its more than likely only 250c silicone
