Venting a pellet stove into existing chimney?
My friends are planning to install a pellet stove in there house for this winter to help cut back on the oil cost, they have the stove already to go in the living room but have yet to get to venting it with lots of other projects at hand. They plan to pipe it into the small i believe 8" diameter hole that leads into the houses existing chimney. I am aware of using double walled stove pipe and heat shields i just am not sure about venting it into an existing brick chimney. i could use any helpful input on this, at this point it seem like someone is going to have to get on the roof an look down the with a light and see the condition and what the inside looks like but im guessing it must have been a pre existing pellet stove or wood stove that vented into the chimney since there is no fire place. I dont know if it is just a brick chimney if we should run steel pipe down it and if so does that have to also be double walled pipe or can we at that point change it to single walled stove pipe to save money? Any input will be great
