Common problems

## Sound familiar?

local\_fire\_department

### Want ambience without the wood and cleanup

A gas fireplace delivers realistic flame and consistent warmth at the push of a button, with no ash, no log hauling, and no creosote buildup in the chimney.

### Not sure which venting type fits your home

Direct-vent, B-vent, and ventless each suit different spaces and ceiling heights. Our TSSA-certified team assesses your layout and recommends the right option for your room.

### Worried about hidden installation costs

Gas line proximity, venting run length, and permit fees all vary by job. We quote everything in writing before starting so the price you agree to is the price you pay.

## What does gas fireplace installation include?

Best HVAC Toronto installs natural gas fireplaces across Toronto and the GTA, handling new full-unit installations, direct-vent inserts into existing masonry or factory-built fireplaces, and wood-to-gas conversions. Every installation is performed by our TSSA G2 certified team, quoted in writing before any work begins, and completed with the required building permit and a TSSA pressure test.

Gas fireplace installation is licensed gas work in Ontario. The technician connecting your appliance to the gas supply must hold a current TSSA G2 certification. Our team carries that certification on every job, which means the paperwork is correct, the pressure test is performed and tagged, and you are not left with uninspected work that could cause problems at home sale or claim time.

The choice of venting type is the first decision every installation depends on. Direct-vent units draw combustion air from outside through a sealed co-axial pipe and exhaust flue gases back out through the same assembly, making them safe and versatile for nearly any room in a Toronto home. B-vent units draw room air and vent upward through the chimney, requiring vertical clearance and an appropriate flue. Ventless units burn without external venting and rely on oxygen-depletion sensors, but Ontario building code restricts where they can be placed. We assess your room, ceiling height, exterior wall access, and gas line proximity before recommending a type, rather than defaulting to whatever is easiest to install.

### What is included in every gas fireplace installation

Supply and installation of the gas fireplace or insert unit, gas line connection from the nearest supply point, venting to the exterior using the appropriate system for your space, permit application and management, TSSA pressure test with the line tagged, carbon monoxide detector placement check to Ontario Fire Code requirements, full commissioning and flame verification, and a 2-year labour warranty on the installation.

## Gas fireplace types we install

### Direct-vent inserts into existing fireplaces

The most popular request we receive from homeowners with an unused or drafty wood fireplace. A direct-vent insert slides into the existing firebox opening, connects to a co-axial liner running up the chimney or through a side wall, and converts the space into a functional, safe gas appliance without major renovation. It is typically the fastest and most affordable path to a gas fireplace in an older Toronto or North York home.

### New full-unit gas fireplace installations

For rooms without an existing fireplace, a full standalone gas fireplace unit is framed into the wall with a new venting run to the exterior. Direct-vent is the preferred option where an exterior wall is accessible. Our team designs the venting route during the site visit so there are no surprises about penetration locations or finishing requirements.

### Wood-to-gas conversions

An existing masonry or factory-built wood fireplace can be converted to gas using an insert and a correctly sized liner. We assess the existing chimney, confirm it is structurally sound, and size the liner to the insert’s venting requirements. The result is a gas appliance using the existing firebox structure, which saves construction cost compared to a full new installation.

## Process and commissioning

Proper commissioning is the step most often skipped by contractors who are unfamiliar with gas appliance work. After the unit is installed and vented, our team pressure-tests the gas supply line, confirms the venting is drawing correctly, measures carbon monoxide at the room level, and runs the fireplace through its operating range before signing off.

The carbon monoxide check is not optional. Ontario’s Fire Code requires a functioning CO detector on the same floor as any gas-burning appliance. We confirm the existing detector is within its service life and correctly placed, and we advise on upgrading to a combination smoke and CO detector where needed. This step takes ten minutes and it is the one that matters most for the safety of your household.

## Gas fireplace installation across Toronto and the GTA

We install gas fireplaces in homes across Toronto, including older Edwardian and post-war bungalows in East York, York, and Etobicoke with existing masonry fireplaces that suit a direct-vent insert, and in newer builds in North York, Scarborough, and the GTA suburbs where a full framed-in unit is the right approach. Custom homes in Vaughan, Richmond Hill, and Markham often have two or three fireplaces that need coordinated gas line sizing so no single appliance starves the others.

The diversity of housing stock across the GTA means venting solutions vary considerably from job to job. An Etobicoke bungalow with a brick chimney and a clear exterior wall is a different project from a downtown Toronto semi where an adjacent shared wall limits penetration options. We plan the route during the site visit and price the job in writing, so you know what is happening and where before we start.

Call 647-254-4113 to schedule a site visit. Our team is available Monday through Saturday, 7 AM to 8 PM, and 24/7 for gas emergencies across the GTA.

FAQ

## Gas Fireplace questions, answered

### How much does gas fireplace installation cost in Toronto?

expand\_more

Most installations run $2,500 to $6,000 depending on the type and venting requirements. A direct-vent insert into an existing masonry fireplace opening is at the lower end. A full standalone unit with a longer venting run lands higher. Permits and the TSSA pressure test are included in all quoted prices.

### What is the difference between a direct-vent, B-vent, and ventless gas fireplace?

expand\_more

A direct-vent unit draws combustion air from outside through a sealed co-axial pipe and exhausts flue gases back out, making it the safest and most versatile choice for Toronto homes. A B-vent draws room air for combustion and vents upward through a chimney, requiring vertical clearance. A ventless unit burns without external venting and relies on oxygen-depletion sensors, but Ontario building codes restrict where they can be installed. We assess your space and recommend the right type for the room.

### Do I need a permit to install a gas fireplace in Ontario?

expand\_more

Yes. A building permit is required for most gas fireplace installations in Ontario, and the work must be performed by a TSSA-licensed G2 gas technician. We handle the permit application and TSSA pressure test as part of every installation, so you have documented, inspected, and compliant work when the job is done.

### What is a gas fireplace insert?

expand\_more

An insert is a self-contained gas fireplace unit designed to fit into an existing masonry or factory-built fireplace opening. It uses the existing firebox space, adds a sealed direct-vent liner up the chimney or through a side wall, and converts an unused or inefficient wood fireplace into a functional gas appliance. It is often the most cost-effective path to adding a gas fireplace in an older Toronto home.

### Can you convert a wood fireplace to gas?

expand\_more

Yes. A wood-to-gas conversion typically installs a direct-vent gas insert with a stainless steel liner up the existing chimney flue. Our team assesses the firebox dimensions, chimney condition, and gas line proximity, then provides a fixed-price quote that includes the liner, insert, gas line connection, and permits.

### Is a carbon monoxide detector required for a gas fireplace?

expand\_more

Yes. The Ontario Fire Code and the CSA B149.1 natural gas code both require a functioning carbon monoxide detector on the same floor as any gas-burning appliance. We verify CO detector placement and function on every installation and recommend upgrading to a combination smoke and CO detector if the existing unit is more than seven years old.

### Do you offer 24/7 emergency service for gas concerns?

expand\_more

Yes. If you smell gas near your fireplace or anywhere else in your home, call 647-254-4113 immediately. We provide 24/7 emergency response for gas leaks and safety concerns across Toronto and the GTA. For non-emergency inquiries, our team is available Monday through Saturday, 7 AM to 8 PM.

### What areas do you serve for gas fireplace installation?

expand\_more
