Two pipes up the chimney
A direct-vent insert breathes and exhausts through the chimney without using the chimney itself. Two flexible pipes, one for fresh air coming down and one for exhaust going up, usually do the job inside an old masonry flue, joined to the insert at the bottom and to a cap at the top.
The pipe lengths and route are measured before ordering, and the chimney top is checked because the cap sits there. Want to know what goes up your chimney with an insert in Keystone Heights? Walk through it with us at (904) 920-5495.

What the insert's listing means
Florida's fuel gas code, in section 605.1, requires vented gas fireplace heaters, the category most direct-vent inserts are listed under, to be listed to ANSI Z21.88 and installed according to the maker's instructions. It also points to 602.2 for how the flame is lit and proven.
In practice that ties every step of the installation to the manual of the exact model: the fireplace it may go into, the vent kit, the clearances and the gas supply. We work from that manual on site, and when a figure in it cannot be met, the answer is a different model or plan, not a shortcut.
Inserts made for masonry fireplaces
Not every gas insert may go into every fireplace. One maker's rating plate states that its insert is for installation into a vented noncombustible appliance only, meaning a masonry fireplace, and adds that it is not for use with solid fuel.
A factory-built metal fireplace has its own listing, and an insert may go into one only where both that fireplace's manual and the insert's manual allow it. We read the rating plates of both before planning anything, and when the answer is no, we say so on the first visit rather than after an order.
Sizing the surround
A gas insert's surround panels come in set sizes, chosen to cover the gap between the insert and the edges of the fireplace opening. Too small and the gap shows; too large and the panels may not sit flat on an uneven face.
We measure the face as well as the opening, including any brick that bows out or a hearth that sits high, and order the surround to suit. Where the face is uneven, the estimate says how the panels will be fitted. The surround is also what gets taken off for service, so it is set to come away cleanly.
Measured in Keystone Heights before a gas insert is ordered
- Fireplace opening width, height and depth against the insert's plate
- Chimney examined and cleaned before any gas appliance connects
- Mantel height and projection measured against the plate
- Surround sized to the face, with noncombustible finishes around it
Before you switch to gas
Do you clean the chimney before the insert goes in?
Yes. A flue that carried wood smoke gets checked and cleaned under the state fuel gas code before any gas appliance is hooked to it, so that is step one.
What is co-linear venting?
Two flexible liners run up the old flue, one bringing outdoor air in and one taking exhaust out. They join the insert at the bottom and a termination at the top.
