How our Bithlo crew fits a gas insert
The practical side of the job, as our Bithlo specialists explain it on site.
Small openings and custom surrounds
Some older fireplaces have openings shorter or narrower than a standard surround expects. Makers plan for it. The Supreme manual notes that custom surrounds are available for smaller openings, ordered through the dealer.
We measure the face as carefully as the firebox. If a custom surround is needed, we say so at the inspection, so the insert and its surround are ordered together. That avoids an insert that fits the firebox but leaves a gap at the face nobody can close neatly.
Setting the restrictor for your vent height
A tall vent pulls harder than a short one. To balance that, many inserts have a restrictor that is set by vent height. In Heat & Glo's table, the restrictor openings stay closed on shorter runs and are opened one at a time, then both, as the vertical run gets taller.
The wrong setting can leave the flame lazy or make the insert cycle on and off. We measure the finished vent height, set the restrictor to the manual's table before the first fire and watch the flame during startup.
Full-length intake or a shorter one
Some insert vent kits let the intake liner stop partway and draw air from the chimney space. Others run the intake all the way to the cap. The Supreme manual describes both and notes that, depending on how clean the chimney is, a full-length intake lessens the chance of fouling the flame sensor.
The same manual says the full-length arrangement may perform better, with less cold-air infiltration, in houses with negative pressure. We explain both options for your chimney and recommend the one that suits its condition and your home.
The checks before the first fire
The owner's manual for the Supreme series lists what a qualified service technician should confirm before a new insert is used: shipping materials removed, logs and embers placed correctly, wiring checked, the air shutter adjusted, the connections tight with no gas escaping, and the glass sealed with its barrier in place.
Our technician works through that list on every installation, with you watching if you like. It turns the first lighting into a planned test instead of a hopeful one.

Gas insert questions we hear in Bithlo
Still weighing it up? Read these, then book the free visit in Bithlo.
Can I put a TV above my gas insert?
Often, if the mantel and the distances in the maker's guidance work and the TV's temperature limit allows it. We check the insert's clearance table and the TV's specifications before the bracket goes up.
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.
