Inside a gas insert installation in Lake Formosa
Plain answers about how gas inserts are installed in Lake Formosa, and why each step matters.
A path for the gas line in a factory-built firebox
A factory-built fireplace may have no hole for a gas line. The Supreme manual allows an access hole of one inch or less to be drilled through the lower sides, back or bottom of the firebox, within its lower half, and says the hole must be plugged with non-combustible insulation once the line is through.
We mark the location with the gas professional before anyone drills, so the line reaches the insert's connection without crowding the surround. The sealed hole is checked again at the end of the job.
Old doors, screens and grates come out first
Glass doors, mesh screens, the grate and any andirons all have to go before the insert goes in. Doors often bolt to the lintel or the fireplace face, and their frames can sit right where the surround needs to land.
Our crew removes them carefully and takes them away, unless you want to keep them. Removal and disposal are listed on the estimate, so there is no surprise charge for hauling off the old hardware.
Adding height above a short chimney
Some manuals allow the vent to continue above the existing chimney in rigid direct-vent pipe. The Supreme manual permits it within the maximum vertical limit, using a named adapter and pipe series, and gives a table that balances the length of flexible liner against the rigid pipe needed above it.
It changes how the top of the chimney looks and adds parts to the job, so we show you what it involves before you commit. Every part comes from the system the manual names, and the finished height is measured again.
One flue for one appliance
Every insert needs a vent of its own. Heat & Glo forbids tying the insert into a chimney flue that already serves another solid-fuel or gas-burning appliance and calls for a separate vent system. Section 503.5.7.1 of Florida's Fuel Gas Code likewise bars connecting an appliance to a flue that serves a separate solid-fuel appliance.
In a chimney with one flue, that is simple. Where a chimney holds two flues, for example serving a second fireplace, we identify which flue the insert will use and keep it apart from the other appliance.

Lake Formosa homeowners ask about gas inserts
Not covered here? Our Lake Formosa team will answer on the phone.
Can I still burn wood after a gas insert is installed?
No. The converted fireplace is labeled for gas insert use only. Going back to wood means removing the insert and its liners and having the fireplace and chimney approved again.
Does a gas insert need a new cap on the chimney?
Yes. The insert's liners end at a termination cap from the same vent system, sealed to a plate that closes the top of the old chimney. An old chimney cap cannot do that job.
