i would like to say hello to everyone here as i am new to the board, i hope i can learn some new things here and possibly help out when i can. i have a question that someone maybe able to help me out with. i have a keystoker hearth coal stove (model 4738)with the rear vent. i want to vent it out through the wall but i dont know if it will work. i took the stove out of my old house which it was inserted into the chimney. this particular model doesnt have a power vent on it so i was wondering if i just run the pipe stait out the back of the stove and outside if it will work the same as if i had it inserted into the chimney. thanks

Welcome to the board. The use of a vertical chimney provides strong convection (draft) to pull air through the stove. The higher the rise in a chimney, the more velocity that is created by the rising hot air. It works a lot like a siphon. Venting horizontally will not work in this case because there will be no draft. Without draft, it is unlikely you can achive sufficient combustion air velocity to maintain a fire. More importantly, you risk combustion gasses entering the home as well as significant soot and carbon monoxide caused by incomplete combustion. Without a chimney, this soot will be deposited at low elevations on and in your house. Also, the incomplete combustion gasses are rich in carbon and can combust unexpectedly. This is a significant fire risk, especially when gasses are released below the ridge line of the structure. You absolutely need adequate height in a chimney to provide the necessary draft and safety.

Failing to achieve reasonably complete combustion by properly designing the system with adequate draft is a dangerous idea. Please don't try to exhaust the stove throught the wall. Any stove pipe through a wall must be in triple wall pipe and must include a continuous triple wall pipe, according to code, to an adequate height above the roof to provide combustion draft and fire safety. Direct venting into a masonary chimney can be done with single wall pipe and the chimney normally provides height for the draft. je5858, I am concerned for your safety. Be sure to check that your insurance includes a schedule for a stove if you install a new stove.

thanks for the advice tomh. i am going to contact the manufacturer of the stove on monday. they advertise as direct venting systems but its better to be safe than sorry. i was wondering because i also have a pellet stove in the garage and the pellet stove can be be direct vented. thanks again for the help.

We are building a new home and are checking out ways to heat our new home. i am really interested in the direct venting and coal stoves. Triple wall is going outrageous and i have about 30' to the peak of the roof. Is this direct venting a good option?
