Engineering notes on installing a wood insert
A liner from the insert to the chimney top
Current insert manuals call for a continuous liner running from the insert's flue collar all the way to the top of the chimney. The old masonry flue becomes an enclosure for that liner rather than the path for smoke. A short connector into the bottom of the flue does not meet that requirement.
We plan the liner as part of the insert, not as an optional extra. The estimate names the liner system, its length and how it attaches at each end. You see the whole path the smoke will take before you approve anything.
Fresh air and other fireplaces in the house
A wood insert uses air from the room, and manuals say to provide a source of fresh air while it burns. One maker notes that an insert can create a downdraft in another fireplace in the house, and suggests slightly opening a window near the unit if that happens.
Tell us about other fireplaces, strong exhaust fans and how tightly the house is sealed. We explain how those affect the insert and what the manual recommends for your layout. The goal is a fire that draws steadily without pulling smoke from elsewhere.
Paint and finishes close to the insert
Heat from an insert reaches the facing and mantel even when clearances are met. One manual warns that paint on a mantel or facing near the unit should be heat resistant, or it may discolor. Dark marks above the opening can also point to smoke escaping during loading.
We point out finishes that are likely to suffer and explain what the manual says about them. Repainting with a heat-resistant product is usually simple before the insert goes in. Afterward, the faceplate can make that work more awkward.
What stays out of the insert
Manuals list materials that do not belong in a wood insert, including treated wood, painted or coated lumber, garbage, cardboard, colored paper, plywood and driftwood. Burning them can release toxic fumes, damage the unit or cause heavy soot. Many wood insert manuals exclude coal as well.
We go over the list at handover, because some items seem harmless. Scrap lumber from a project, packaging and gift wrap all fall into the excluded groups. Natural wood that is dry and split is what the insert was tested with.

- Appliance connector and high-temperature sealant
- Metal tag fixed to the fireplace

Wood insert installation, in questions and answers
Is a wood insert allowed in a factory-built fireplace?
Only when both the fireplace's listing and the insert's manual allow the pairing, and many do not. We read both labels during the inspection and explain what they say before you consider any model.
How close can furniture sit to a wood insert?
The manual for your model sets the clearances and the protected floor area, and furniture belongs outside them. We point out those zones at handover. Keep rugs, cushions and stored wood out of the area in front of the loading door.
Can the insert share a flue with another appliance?
The selected insert and liner manuals determine the permitted arrangement. The DuraLiner system cited here calls for a dedicated liner. We check whether another appliance already uses the proposed flue and record the compatible connection before installation.
