Question Chimney Liner

I want to convert my existing wood burning fireplace over to natural gas. The existing fireplace has a "Heat-O-Lator" insert with a top closing damper between the firebox and the chimney.

How do you connect and install the flexible chimney liner to the new gas fireplace unit when the existing damper is in the way?

Do I have to torch out the existing damper and fit the flexible liner through?

Other suggetions?

Dave

Dave,

It's gotta come out....how you do it is your choice but the new liner will not work unless this is done. If anyone has some good ideas, we need to hear it!

Good Luck!

Fireplace conversion

Contact your local building inspector. Some areas will not issue a permit unless a licensed professional does the conversion.

We live out in "the sticks". The closest building inspectors are 100 miles away and waiting for one of them to drive here would take two-three years. Our area is not high on their priority list.

Doug.....From what I gather, the damper itself must be removed.

I certainly hope that you did not recommend removing the entire Heat-O-Lator insert. If that's the case.....Forget the gas log unit.
The fireplace is a beautiful stone structure that goes the entire height of the room (cathederal ceiling an all)..... I don't want to mess with the stone structure in ANY way.

I can get into the firebox area and possibly take out the damper. How are they fastened in place? Just the weight of the damper itself resting on some pads? What?

Any good suggestions on how to remove the damper?

Dave

Dave,

Not knowing or seeing the damper, I am unsure how it is installed. Some set within the throat atop the brick. You may have to cut it out with a torch. The other issue is the diameter of the space to allow for the liner to connect. Is there a jog that you have to contend with? You may not have enough roomj or if you do, how much of an angle is going to be required. You'll have to take a good look and see. I have attached links for further info;

Might not want to do this if severe alterations are need.

Chimney liner

You might want to have a certified chimney specialist take a look before you begin the project.
