Coal stove chimney

The Channing II will accept the Alaska power vent system, won't it? That would certainly be the easiest way to go.

I have a gas and coal boiler hooked up to the same stainless steel lined chimney. But only one boiler is working at a time, never both. The width of the chimney dictates how many btus can be burned. I have a 7" chimney. Which means that the most btus I can burn at one time is around 230,000. More than I need.

Only wood makes creosite. This can cause blockage. But another hazard is coal smoke. It goes as follows. Coal burns super hot. The vapors rush out of the chimney. It does leave some byproduct on the chimney walls. And its harmless. Oil and gas burn cooler. When the vapors go up the chimney it does cool down and condensate. When this condensation mixes with the coal byproduct, that mixture makes an acid. Which can eat through morter and brick. But since you're stainless steel, as I am, we're ok.

the best coal chimney is masonry/tile lined; it can and probably will last for centuries with coal, even 316ti stainless will only last decades although that may be fine for most people. a block and tile chimney will probably cost much less than stainless if you do it yourself. while code does only allow same fuel types to be conected to chimney, you will be fine doing it with your furnace, the only real concern in conecting two + appliances to the same chimney is that if one of them burns wood, produces creosote, in the event of a chimney fire, how easy is it going to be to shut off the air to the chimney? much more difficult esp. if it's an oil furnace with a baro etc. the reason that seems to be mentioned on this board that two + appliances can't be connected if they burn different fuels (aside from code saying no), fear of CO entering the house if they are at two different leves etc. is complete horseshit (if the chimney can physically handle the exhaust gas volume it will never happen and this can be figured out very easily)

I glade thses installations are not in my town I don't have to deal with them The code and manufactures specs tell you what is approved tested and listed.
not someone's guess as to what they want to hear and justify their situations It is dead wrong to advocate to others its ok to violate code and manufactures specs. because I do I can list the language in the oil burner code NFPA 211 Y the International Mechanical codes it all the same Hey if you don't like the code then petition for an amendment. After all you elected and appoint officials approved it don't vote for the guy that approved a code you do not argee upon. I bet the insurance companies know the code as well. Instead of discussing it here ,then why not ask the code official that is going to issue the permit. After all its his signature you require. No one here can justify code violations in you situation nor should they be so foolish to advocate them

Ask them if they would be willing to help pay the fine violations for each day, the code violations exist? In my state that can be up to $500 for each violation per day.
