The most common way a stove installation goes wrong is sequence. The appliance gets chosen from a showroom or a website, it arrives, and only then does anyone look at the chimney it is going to be connected to. By that point the decisions that mattered have already been made.
Here is the order it should happen in.
1. Survey the chimney
A full inspection of the flue. This establishes whether the chimney is sound, whether it is lined, what condition that liner is in, and — critically — what size the flue actually is. Changing the appliance changes what the flue has to do, which is exactly why it gets checked first.
2. Size the flue to the appliance
This is where the existing chimney usually fails. Masonry flues were built for open fires, which need a large cross-section to carry a lot of low-temperature exhaust. A modern stove produces far less exhaust at much higher efficiency, and putting that into an oversized flue means the gases cool before they reach the top.
The consequences are all the ones people then complain about: poor draw, smoke in the room on lighting, rapid creosote build-up, and acidic condensate attacking the liner. The fix is a correctly sized stainless liner, insulated if the stack is cold or external.
3. Settle the hearth and the clearances
A stove needs a non-combustible hearth of a specified size, extending in front of and to the sides of the appliance. Clearances to combustibles — walls, mantels, beams, furniture — are set by the appliance's own listing and are not negotiable. Reduced clearances are possible with listed shielding, but "possible with the right shielding" is a design decision, not something to discover on install day.
4. Plan the liner route
How the liner gets from the appliance to the top: through the damper plate, up the existing flue, terminated and sealed at both ends. Offsets, bends and the state of the smoke chamber all affect what is achievable. This is also the point at which any masonry repair gets scheduled, because doing it after the liner is in is far harder.
5. Then choose the appliance
By now you know the flue size you can work with, the clearances the room allows, and the hearth you are building. The appliance decision becomes straightforward instead of constrained by things you have already committed to.
6. Install, commission and certify
Commissioning matters as much as fitting. The installer should run the appliance, confirm it draws correctly under the conditions the house actually operates in, and show you how to run it — how to establish the fire, when to close the air down, and what a correct burn looks like.
Then the paperwork: the certification your insurer will ask for, and that a future buyer's inspector will ask for.
Inserts, specifically
A fireplace insert is a stove designed to sit inside an existing masonry fireplace, and it is the most common upgrade in Connecticut housing stock — an open fire loses most of its heat up the flue, and an insert recovers it.
The single non-negotiable is a full-height liner connected directly to the insert. An insert vented into the void of an open fireplace, with no continuous liner to the top, is the classic bad install: it draws poorly, it builds creosote in a space nobody can sweep, and it is very difficult to service afterwards.
What we do
ABC Chimney Solutions handles the whole sequence as wood and pellet stove installation, including the correctly sized stainless liner that almost every fireplace install turns out to need. Installations we have completed are on the projects page.
Frequently asked
Do I need a permit to install a wood stove in Connecticut?
Solid-fuel appliance installations generally require a building permit and inspection, and the requirements are set locally rather than statewide. ABC Chimney Solutions handles this as part of the job. It also matters later — an unpermitted install can surface as a problem during a sale or an insurance claim. Learn more about this service.
Can I put a stove into a fireplace without relining?
Occasionally, if the existing flue happens to be correctly sized and in sound condition — but that is uncommon. The flue built for an open fire is typically several times the cross-section a modern stove wants. ABC Chimney Solutions inspects the chimney first, because that answers it definitively. Learn more about this service.
How long does an insert installation take?
A straightforward insert with a new liner is usually a single day on site, occasionally two where masonry repair or an awkward liner route is involved. ABC Chimney Solutions carries out the inspection and any repair work ahead of the install date rather than on it. Learn more about this service.
