Why such a short burn?

[deborita3]

I reloaded the stove at 3:00pm with five logs. Stove temp reached 650. It's now 5:30, fire is out and the stove temp is down to 350. I had the air shut down. I have read here where people are getting 6-8 hours. Why am I only burning for 2 1/2 hrs?

When you shut the air down do the flames get lazy?

How tall is your chimney and is it insulated?

Could you tell us more about your wood size m/c length of chimney photo if available

Yes they get lazy, flare up and get lazy again. I don't know how tall the chimney is. It runs up the side of the house. I had a new liner put in a couple months ago. It's not insulated at the bottom because I was told there wasn't enough room to insulate it but it was insulated at the top. I was told this wouldn't have any effect on heating the stove.

If yourey getting it to 650 I doubt it's wet wood. Sounds like too much air getting in the firebox (although lazy flames sort of contradicts this).

With my insert I found my primary air to close down enough but I get too much air through my secondary tubes. This causes the wood to burn hot and fast.

Did you try the dollar bill test on the door?

How much space are you heating tall ceiling?

 

[deborita3]

The wood is between 15" and 17"

Blower speed need some more info type of wood

My had done the test and the bill comes out. We need to get a new gasket. Could this be the problem?

Blower speed need some more info type of wood

I have found when I out the blower on it lowers the temp which makes sense. I was putting the blower on medium but lowered it to low speed. The problem with lowering the blower is that the house doesn't get as warm obviously as it does when the blower is higher.
The wood is a combination of oak, maple and locust

Yes problem with gasket for sure also your chimney needs a insulated liner or wrap

The liner was insulated at the top. I was told it could not be insulated down below because there wasn't enough room to do it.

 

[SculptureOfSound]

Yup, first thing to do is replace the gasket.nif the problem still exists we can troubleshoot further but a loose door gasket will inevitably lead to too much air and short burn times

 

[SculptureOfSound]

Well for code reasons the liner should be insulated but I was actually asking because an insulated liner can lead to increased draft, and I thought you might have too much draft. That too can lead to short burn times and reduced heat.

Keep heat in the liner instead of heating the brick is this a zero clearance fireplace

The entire liner is suppose to be insulated? Does this vary from state to state or is this the case in every state. Is it a safety issue if the liner is not insulated?. I will have to call the place that installed it.

How much space are you heating tall ceiling?

The living room has a vaulted ceiling, the other rooms all have a normal size ceiling. It's a ranch house.

The upstairs is 1070 sq ft

Bholler is the expert on this but yes it is for safety reasons in the case of a chimney fire. The insulation helps stop the heat spread and greatly reduces the chance of a chimney fire turning into a house fire.

I think external chimneys need a 1" clearance to all combustibles to be up to code and very few have that. Without that 1" clearance an insulated liner is required.

Unless you have 1" of clearance between the outside of the masonry structure and any combustible material (which having that clearance is very unlikely) you are absolutly required to have an insulated liner.

Ah heck you knocked me off my pedestal LOL

I wasn't told that when it was installed. I will call Monday to find out. Thank you for the information!

Many installers dont seem to care about being code compliant.
