Austroflamm Integra cast iron pot repair???

[shumiron]

I have gotten hold of a good condition Austrflamm Integra pellet stove that has a broken cast iron burn pot. The pot has broken around the circumference about 1/3 of the way down so it is in 2 pieces - the top ring and the bottom "cup". The integrity of the 2 pieces seems pretty good. Can these 2 pieces be spot welded together? Or is it safe to use the pot as is with the top ring sitting on top of the bowl piece, lined up so they fit snugly together? The previous user of the stove said he used it for several years like it is without any issues. also is it possible to add an igniter to this stove?

A new pot is 150,recomend purchase.Could be critical at higher burn rates,As you will be scraping pot once to twice a day,do not see how he was doing this?Probably why got rid of stove,make sure you dissasemble and clean stove.You probably could still get all the parts from energy parts plus to add ignitor,but why?Stove will not self start on thermostat,and you can manualy light it in under 1 min.

Thank you for the info. I will follow the maintenance recommendations on this forum before I start using it. I am replacing an old wood burner that has a manufactured steel chimney pipe (8" ID) with a 6" stove pipe with a 6" to 8" adapter to the chimney. Is it safe to use a 3" to 6" adapter to the stove pipe from the 3" exhaust pipe coming from the stove?

If a new pot is as bob states that's the way to go. A welding shop could attempt welding with a high nickel-stainless electrode. First heating it before welding to prevent more stressing.

Yes you can.Mine has 4" off the stove,2 t's and goes into 8" lined chimney I built years ago.The thing about the older integra is it will adjust burn by reading airflow.The only question would be if it is legal in your part of the country,government employees have a knack of making up their own rules/laws that don't exist.

Thanks for the welding tips. I will take it to a shop and provide the info you posted.

Welding of cast is very problematic, very few people can do it and then in the application of your cast it will not last, get a new pot.

Speaking form experience here and in this case the application was nothing remotely to what you are going to use it for.

It would cost more to repair it.
I have done a lot of cast iron welding, and it's a very involved process. High Nickel rod is a must, as is preheating the piece to be repaired, then it is welded and cooled down SLOWLY, using map gas and propane torches to bring the temps down. It would be a lot easier to buy a new one.

I agree,welded up my tractor manifold this summer.I rough est. that just the rods to do the pot would push the $100 mark.

I must have learned from a pro but I have welded probably tons of cast iron. Not hard as a smaller pump housing was half ton +. Stove pots etc. are the biggest pain because of the temperatures will put stress on the weld and if not beveled out enough for enough of the filler material to bond to the base it will just break. You don't melt the base metal but use the filler material as an adhesive. $15 for 4 sticks of 1/8 Nickel rod

I don't have to scrape my burn pot as often as Bob suggests, but I do agree with him that just getting a replacement is the way to go. I learned a long time ago that it's often easier to just buy a thing and be done with it, than to spend twice as much and taking twice as long for a Do-It-Yourself fix.

Agreed, get a new pot. Cast Iron is a pain to weld and it won't hold up.
