Buying a stove by accident

[lostinthelight]

Back of the #3, no crack I think just a rust stain from the flu.

Think it's ok, just a scratch.

Looks ok but nice to view under the smoke outlet flange to be certain?

Thanks for the tip, will see about getting a better look at it.

It probably is a thermal crack, and believe it or not it doesn't have to go right through the metal.....cast iron can be malleable to a degree.
That's why the top 'lid' of the stove needs to be allowed to float, i.e not bolted down too tightly.
I've seen this before, and there has been no smoke leakage to the outside but I'd always sure a CO detector was used in the room.

Do I need to worried - am I looking at a new back plate?

 

[Burnerman]

No, I honestly don't think so......cracks can appear in cast iron later if it's allowed to cool to quickly, and a stove environment is pretty hostile - being heated and cooled many times in it's life. I've seen this before, much worse than yours - and there was no escape of fume. Epoxy putties are available for severe cracks, and yours seems negligible.

TaDa! One week of penetrating oil and two hours of careful cutting a bolt with a dremel later (gotta be a faster way), and the flu is off.

You can see the full length of the mark/crack here.

Any idea what the white rubbery stuff is?

 

[Burnerman]

If what we can see there is the full extent of the crack (if indeed it is one) I'd forget all about it.
The white stuff is likely to be high temperature silicone sealer.

Funny they don't use fire rope there also.

A rope seal is typically around 8mm in diameter - and it needs a corresponding groove for the rope to sit in. I can't see a large groove in your flue outlet which is maybe why they expect you to rely on fireclay cement or high temperature silicone.

Couple of bad spots of rust.

1. The underside of the stove - clearly leave it out in the garden didn't do it any good.

2. Toe of the one of the legs.

I was just going to wire brush the underside and spray down with WD40, and leave as is.
Would like to tidy up the leg a bit, but the stove is enamel so it is tricky.

Any tips?

Jotul use a ceramic gasket material if there is no rope grove.
