Hooking up new to me pellet stove

I am going to hook up my new to me pellet stove this weekend. As far as I can tell the 4 inch stainless pipe goes over the outlet in the stove. I purchased a 4 inch to 6 inch conversion because I already had a 6 inch pipe in the chimney. My question is this do I need to use any high temp putty at the stove to pipe junction or the pipe to conversion junctions? Thanks!

Yes. Or you can use high temp foil tape to keep any leaks to a minimum. Smoke is sneaky stuff when it's under a little preasure unlike a wood stove that depends on a negative draft. Try run your stove outside awhile before moving in to hopefully chase down any bugs before moving inside only to find out why you got the used stove.

A adapter is used to hook up the pipe to the stove. The stove pipe does not hook up directly to the stove. It is a special part for hooking the stove up.

Most use putty/high temp stuff and screws to hold the adapter onto the stove and yes, tape can also be used if you want to be xtra safe or if you find you have a leak.

Simpson vent elbows are loose and leaky. If you vent into an existing chimney first use pellet venting to have a bit of velocity to keep ash build up away from the stove. Elbows really make for a poor evl quick. Others more experienced(I have not done a for hire install in several years) than me can hopefully chime in and make your install as painless as possible and stove run without any venting problems anyway.

The first thing you need to do is a full tear down cleaning of that stove.

Then a burn test outside to find anything else that might be wrong.


They usually wind up on the market because they weren't properly maintained and no longer work like they first did.

Did a full cleaning of the stove. Good call on the test fire!

How hot does the venting get? I am guessing not as hot as a wood stove???

My plan was to use the 4 inch vent off of the stove and then put the adapter on the end of that 4 inch vent and then run my 6 inch into the adapter. I know I am supposed to put the adapter on the stove, but my 6 inch pipe won't reach to the stove and I do have several feet of 4 inch that came with the stove. Also, it looks like I would have to cut the rear fan covers to make the adapter fit. Is all of this okay to do? I have installed several wood stoves, but never dealt with a pellet stove. Thanks.

Claybe,
The adapter they are speaking of is actually called an " appliance adapter" not to be confused with the 4" to 6" adapter.
2 different critters.
The appliance adapter should be the first piece coming off of the stove, then your run of 4" pipe to the 4/6" adapter.......
Hope that cleared it up a bit

what stove this be? usually, if is correct adapter you should not ned to cut anything off the stove.

Ahhhh, that makes sense. I do have the adapter to hook it up to the stove. It does look like the previous owner just put the the stove pipe right over the exhaust exit as it does stick up like 4 inches. Is this okay to do, or should I use the adapter? Thanks for all the advice!

Oh, the stove is an Earth Stove.

The proper way to connect the 4" pellet vent pipe to the stove is to use an appliance adapter, as Brewer states above. If the stove exhaust is 4", then just a 4" appliance adapter is needed.

If the stove had a 3" exhaust, there are 3" --> 4" appliance adapter available too, although you didn't specify what brand of pipe you're using on the back of the stove.

Here is what I am dealing with. The first picture shows the stainless steel pipe that fits snugly over the exhaust outlet. The next two show the exhaust outlet. The adapter does not fit in or on this exhaust outlet. The drawings in the manual I was given show what look like the pipe fitting over this exhaust outlet as shown in the first picture. The exhaust outlet opening measures 3 7/8 inches.

It appears that the flex pipe in first pic is single wall, is that approved for pellet stove use?

You never mentioned in your previous posts that you were going into a chimney liner.

It came with the pellet stove and the guy was using it just like this. I assume its okay.

Yes I am going from 4 inch to 6 inch stainless steel chimney liner hence the 4 to 6 inch converter.
