The engineering behind a gas insert in Otter Lake
A few of the things our installers walk Otter Lake homeowners through before an insert goes in.
What happens to the old damper
The liners for a gas insert pass through the damper opening on their way up. Heat & Glo tells installers to lock the fireplace damper fully open or remove it completely. A damper left free to swing can pinch the liners or drop onto them later.
Some dampers leave room for both liners once they are locked open. Others are too tight and come out. We decide which at the inspection and describe the choice on your estimate, including any cutting or modification the damper needs.
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.
Sealing where the gas line enters
The gas line reaches the insert through an opening in the unit or the old firebox. The Supreme manual allows the gap around the supply pipe to be sealed with caulk or aluminum foil tape rated for at least 300 degrees continuous exposure, or stuffed with non-combustible unfaced insulation, to prevent cold air infiltration.
It also says the gas line must not touch the outer wrap of the appliance. We route the line with that clearance and seal the entry point before the insert is pushed into its final position.
Setting the air shutter
Many gas burners have an air shutter that controls how much air mixes with the gas before it burns. Heat & Glo lists the air shutter setting among its installation steps and puts it on the installer's checklist, set according to the type of installation.
The setting affects flame color, flame height and how much soot builds up on the glass. We set it to the manual's figure for your installation and look at the flame again once it has warmed up.

Common gas insert questions in Otter Lake
Still weighing it up? Read these, then book the free visit in Otter Lake.
What if I smell gas after the install?
Get out of the house at once and phone 911 or your gas utility once you are outside, without lighting anything or touching switches or phones on the way. Once the utility says the house is safe, our team will come back and check the installation.
Will a gas insert make my room too hot?
That depends on the size you choose and the room. Inserts are listed with a range of inputs, so we match the model to the space and the way you use it. Many models also let you turn the flame down.
