Fireplace Flu liner ?

bigdog · 12-20-2014, 10:57 AM

I currently have a 4" stainless steel liner, setup for a pellet stove.
A very costly endeavor !

SS Liner connects to pellet stove then into my clay-lined brick chimney,
and extends to the top of chimney, where it has a flue cover with rain cap.

That said, would it be at all possible to covert from pellet to wood stove application?

I know most wood stove venting applications call for a 6" pipe, I suspect that is standard for venting? Would my 4" SS line be acceptable for wood stove application? Just asking?

Thanks
Bigdog

You need to use a 6" liner.... I have one for my wood stove which runs inside a masonry chimney. Furthermore you should talk to your fire department to get current code as they may differ a bit from town to town.

If you try to "neck down" your pipe you will adversely affect the draft for starters. I don't believe those pellet stove liners are anything like the wood stove ones in regards to their makeup since they do not have to withstand the same temperatures a wood stove will put out. Also the wood stove liner I had put in was insulated to retain the heat in the pipe to reduce the potential of creosote buildup. That cost a little extra but well worth it, every year I clean my pipe there is very little buildup after a full season of non-stop burning.

This is something you really don't want to screw around with, trust me I had a really bad chimney fire that almost took my house because I decided to cut corners on my wood stove installation. I learned my lesson. Also it's a good way to void your homeowners insurance policy.

Yes these liners are very expensive.

A 4" flue is not acceptable...

Burning wood you need to use ALL FUEL chimney. Double wall stainless steel. Need to check local codes. Many of the city and towns may adhere to different codes.

Are you ready to give up on your pellet stove already??

I just had my old brick chimney lined with ceramic. The old clay liner was gone due to the association rules that will not allow modern stainless steel vents that are required for efficiency furnace or heaters. The HVAC tech warned me and the association directors that it will destroy the chimney.

Now that it had happen, the association did an expensive 'cast in' ceramic flue. Suppose to be much better than stainless steel which will break down in a long burn chimney fire and over time corrode. The ceramic flue should last a lifetime but it is subject to cracking should the chimney ever move.

Thought you might want to check that out.

Yes Blue Thunder,
havng second thoughts about burning with a pellet stove......
If I had to do again, I would have purchased a wood stove.

Pellet stoves can be tricky to run, and the stoves have many working parts which can fail, and be costly !

I have a wood fireplace insert at my other location, and love it !
Easy maintenance, and only moving parts are the blowers, which can easily be replaced. Also, firewood is usually readily available.

Sorry to hear you're not enjoying your stove. Those of us with Harman stoves have the advantage of a superior product. I have had a pellet stove for 19 years and burned wood for many years prior to that. I wouldn't go back even if the wood was free....

Speaking of Harmon stoves, I have one of their wood stoves. Absolutely fantastic stove and what I like about Harmon is they don't skimp on anything. It's well made, durable and good looking. It's also surprisingly efficient providing a nice long burn.

My sister has a Harmon XXV pellet stove and that's a real beauty too. Yes they are expensive but well worth the investment.
