Freestanding gas stoves are a third route when there's no wall to build into. Built-in units are typically zero-clearance designs, and our zero-clearance fireplace guide explains what that means for the surrounding framing.
Sizing for indoor heating
Match the heat output to the room, not the whole house. An oversized unit cycles on and off and can overheat a small space. You'll also need to choose between natural gas and propane, and between thermostat and remote control. If you're comparing vented and vent-free designs, read how vent-free gas fireplace installation works before you commit.
Getting the Kingsman fire to look right
The flame in the product photos depends on details set during installation. The logs, glass or stone media must be placed exactly as the manual shows. The gas pressure is checked at the appliance. The vent run has to stay within the manufacturer's length and elbow limits. If any of these is off, the flame can look lazy, sooty or uneven. We set each one by the manual, then run the unit and watch the flame before we leave.
Kingsman fireplaces installation in Hartford and East Hartford
Whether it's Kingsman Fireplace Installation in Hartford, CT or Kingsman Fireplace Installation in East Hartford, the job usually has three parts we handle. Those are setting up the appliance through our gas fireplace installation service, running the gas line to it and finishing the surround or chase. Inserts also need a chimney inspection and a liner run first.
Have the model number ready when you request an estimate, so we can review the manual before the visit. For a quick refresher on the components involved, see the fireplace anatomy guide.
What happens during the visit
Clearances to combustibles are set by the manufacturer and the building code. Venting must match the appliance's listing or it won't draft or pass inspection.
Look at the space
The opening, wall or chase, the chimney and the fuel available are checked.
Choose the unit
Size, fuel and style are matched to the room and the venting.
Install
The unit and its venting are installed to the manufacturer's instructions and local code.
Test
The unit is fired and checked, and you're shown how to use it.
What the technician checks
- Gas supply or electrical needs
- Permit requirements
- Vent or liner route and length
- Opening or framing dimensions
- Required clearances to combustibles
- Hearth extension and protection
How to prepare
- Make sure the technician can reach the roof or attic access if it's needed.
- Keep pets in another room while the work area is open.
- Write down what you've noticed and when it happens — smells, smoke, sounds or stains.
- Let the fireplace or stove cool completely — ideally no fire for 24 hours before the visit.
If you smell gas
Leave the home right away, don't use switches or phones inside, and call your gas utility or 911 from outside.
Signs to watch for
- A switch from wood to gas or electric
- A worn-out insert or stove
- A remodel that adds or moves a fireplace
- A damaged factory-built unit past repair
- An open fireplace that sends most of its heat up the chimney
