Stove Venting into a fireplace

Stove Venting into a fireplace

PostBy: WJSlater On: Wed Sep 18, 2013 12:59 am

Hello, I recently bought a reconditioned Chubby Sr. from Larry Trainer at Chubby Stove Co. The stove is a blower model and it is like brand new ! The work done by Larry is first class in every way, and he's great person, full of story's and information about these stoves. My question that I need help with here is, where my installation is going to be on a fireplace hearth' venting into the masonry chimney through my fireplace. My problem is that the six inch stove pipe is two large to fit through the throat of my chimney. So I have the option of closing off the fireplace and venting directly into the fireplace, but I understand that this type of installation reduces the draft. So I have two questions, would it be better to have fabricated some kind if sheet metal closure at the throat with a six inch rectangular opening and just venting into the fireplace or can I reduce the size of the pipe so it will fit through the throat and run the pipe up the chimney ?? Which way would I have the best draft ?? or any other suggestions out there would be welcomed.

Hey WJSlater, I had the same issue 2 yrs. ago and was able to oval the pipe slightly going through the throat of the fireplace damper. I had approx. 5 -- 5 1/2 inches to work with and had the pipe continue above the throat a foot and a half into the terracotta liner. I then blocked the face of the fireplace with a piece of half inch dura rock I think it cost me ten bucks plus a few bucks for a tube of furnace cement for the edges and achieved my goal :)

I have a stove in front of my fireplace also. I got a 5' piece of 316 ss flex chimney liner (local stove shop sold it to me for a couple bucks because it was left over from a job). Take a 2x4, 2x6 ect and use it to press the top 1/2 to 3/4 into an oval shape. put the oval end up into the terracotta and reach up in there and stuff insulation (no paper backing) to fill the extra opening. Then at the bottom I have 2 t's of stove pipe, 1 as a clean out, and 1 with a baro damper. Been using this set up for 3 years and works great. I have a very strong draft.

you can read my thread here that may help you somewhat understand what I did in the same situation (granted, my damper was "toast" either way so it made my remedy an easy decision), a 404 is a stove designed specifically for existing fireplace/hearth install where a chubby is more suited for free standing (though Larry did make it with rear or top flu knowing it would be more adaptable to both).

I would remove the damper and use a 6" round to oval adapter to go through the damper throat. Seal around the oval pipe with Fiberglas insulation.

Thank you all for your information, I was worried that if I just made the pipe oval I might run into problems, I'm glad to see that you guys have been running these setup's for a number of years with out problems. Thank you again for your help and input.

Take some pics while your doing the work and post them as you go. We love pictures. It gives our lips a rest from all the movement when people just type things and post them.
