Types of Gas Fireplaces We Install
Gas Inserts
Fits into an existing masonry or prefab wood-burning fireplace. Highly efficient with a realistic flame. The most popular upgrade choice for Toronto homes.
Built-In Gas Fireplaces
Installed directly into a wall or framed surround - ideal for new builds and renovations. Linear and traditional styles available.
Direct Vent Fireplaces
Sealed combustion system vented through an exterior wall - no chimney needed. Safe, efficient, and flexible in placement.
B-Vent Fireplaces
Uses room air for combustion, vents up through a traditional chimney flue. Often used to replace existing wood-burning fireplaces.
Vent-Free Gas Fireplaces
Requires no venting at all - 99.9% efficient. Suitable for supplemental heat in well-ventilated spaces. Check local code before choosing this option.
Freestanding Gas Stoves
Classic stove-style gas heaters that stand anywhere there's a gas line and venting option. Great for basements, cottages, and supplemental zones.
Who Installs a Gas Line to a Fireplace?
Running a gas line to a new or existing fireplace location requires a TSSA-licensed gas technician (G1 or G2 certified). In Ontario, this work must be permitted and inspected. EcoFrost handles the full process - from pulling the permit to booking the TSSA inspection - so you have nothing to worry about.
Gas Line Rough-In for New Fireplaces
If you are installing a brand-new gas fireplace in a location with no existing gas supply, we will run a dedicated line from your home's main gas system to the fireplace location. This includes sizing the line correctly for your unit's BTU requirements, routing it through walls or floors, and installing the appropriate shut-off valve. See our full gas line installation service for details.
Gas Line for Fireplace Replacement
Replacing an older fireplace - such as an Olympic or Kingsman unit - with a new model? We assess whether the existing gas line is the correct size for your new appliance and extend or upgrade it as needed. If your old Olympic fireplace needs repair instead of replacement, our technicians are experienced with Olympic units and carry common parts. Need urgent service? Contact our 24/7 emergency team.

Gas Fireplace FAQs
How much does gas fireplace installation cost?
Gas fireplace insert installation typically runs $1,200–$2,500 installed, depending on the unit selected and whether a new gas line is needed. Built-in fireplaces with custom surround work can range higher. We provide a free, detailed quote.
How often should a gas fireplace be serviced?
Once per year, before the heating season. Annual servicing keeps the burner clean, ensures the venting is clear, and verifies all safety controls are working - similar to furnace maintenance.
My pilot light keeps going out - what's wrong?
The most common cause is a failed thermocouple or thermopile - an inexpensive part that tells the gas valve it's safe to stay open. This is usually a 1–2 hour repair.
Can you convert my wood-burning fireplace to gas?
Yes. A gas insert is the most popular conversion option - it fits into your existing masonry fireplace opening and provides efficient, clean heat with realistic flame effect. We handle the gas line and venting.
Do gas fireplaces need a chimney?
Direct vent fireplaces use a small coaxial flue that can be vented through an exterior wall - no chimney required. This makes them ideal for rooms without an existing chimney.
