Chimney liner question

Chimney liner question

PostBy: italia899 On: Wed Aug 02, 2006 10:38 pm

Hello all,

I have a coal burning insert and am getting ready to have a liner installed into my existing masonry fireplace. However, I have a dilemma: my flue has clay tiles in it.

The first installer stated that he'd have to remove all the clay tiles to get a six inch diameter or more liner inside the flue. He said this process, plus the liner, plus install will be very costly. He has not offered me other options.

The second installer stated that he could remove the damper and install a stainless steel liner up through the smoke chamber, stopping at the clay tiles. He stated this is safe and I will achieve a good draft.

I plan on burning my insert 24/7 with anthracite. I plan on being in my home the next 4 years and am not planning on taking my insert with me. What are the pros/cons of the second installer's method? Do I really need the stainless steel liner all the way up my 30 ft chimney? Will the clay tiles provide some draft?

I live in NE Ohio.

Thanks!

Why do you need a new liner? Is the old one cracked? To my knowledge, a stainless steel flue is not required to burn anthracite. All you need is a good draft from a sealed flue with structural integrity.

mikeandgerry,

My clay tiles are not cracked and look to be in good shape. The insert I have requires an 8 inch flue and my flue is 8x12 inches

Check with the manufacturer and the code people before using the existing chimney...it may be too big for your appliance at 8x12. Square and rectangular chimneys have an effective venting area. That area must fall within the range of the mfr recommendations while still producing a natural draft to the requirements of the appliance. Installers don't always have the right information. The mfr of your appliance will and the code bureaus involvement will keep your fire insurance in force.

mikeandgerry,

I stated my dimensions to the manufacturer and its representative stated I should have no problem with getting a draft. It is a rectangular chimney.

8x12 is fine, absolutely NO need to reline, as i've said hundreds of times, relining a decent condition clay tile chimney with stainless is completely unnecessary and your installer is blatantly lying to you if he says you must reline.

Berlin and all,

Do you recommend insulating the liner based on the above posted description of my chimney?

first of all if it were me, i wouldn't be relining at all, however if you do wish to reline, first have the chimney cleaned very well, then i would insulate the liner, if you are going to reline, you might as well insulate it. also if you are going with a stainless liner for coal make sure that you use a 316ti stainless otherwise your liner may have a very short life, with coal the best liners are hands down clay.
