Fitting a gas insert to your Corner Lake fireplace, explained

Written by the family-owned crew that fits gas inserts across Corner Lake.

Insert vents run straight up the chimney

A built-in gas fireplace can sometimes vent sideways through a wall. An insert in an existing fireplace uses the chimney that is already there. The Supreme manual is plain about it: terminating horizontally is not allowed, and vertical terminations are measured to the top of the chimney.

That is one reason the chimney's condition and height matter so much here. If the chimney cannot carry the vent, an insert may be the wrong project, and we will say so and explain what else could work.

Liners that run tight and straight

Flexible liner is easy to push into a chimney and just as easy to leave with a loop or a sag in it. The manual says the vent must not sag below its connection to the appliance, and that excess liner is pushed back up into the chimney without sagging.

A sag can hold condensation and restrict the flow. Our crew sizes the liner to the chimney, keeps it straight through the smoke chamber and checks it from below before the insert is set in place.

The reset switch on the surround

Some inserts have a switch that must be on before anything works. The Supreme series has a reset switch and battery plug attached to the side of the surround, and its manual says the reset switch must be installed and in the on position for the appliance to operate.

It is the kind of detail that causes a service call a month after installation. We point it out at the walkthrough, so if the insert ever seems dead, the first thing you check is a switch you already know about.

Keeping the insert and controls dry

Gas appliance makers are firm about water. A Hearth & Home Technologies manual warns installers to keep the appliance dry, because moisture can lead to mold or rust odors and water can damage the controls. It also says any appliance or gas control that has been under water must be inspected by a qualified technician and its control parts replaced.

Before an insert goes into a fireplace, we look for signs of water coming down the chimney. A leak at the top is fixed first, so the new controls start life in a dry firebox.

Gas fireplace insert FAQs for Corner Lake

Answers from the family-owned team that fits gas inserts in Corner Lake.

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.

Will a gas insert work during a power outage?

Many electronic-ignition inserts include a battery pack for outages, and Heat & Glo's Supreme series is one. The maker treats batteries as an emergency power source only. We show you how your model handles an outage at handover.
