Gas Fireplace Installation in Trenton & Quinte West
A gas fireplace adds warmth, ambiance, and supplemental heating to any room — and the gas connection must be installed by a TSSA certified technician. Johnston Mechanical HVAC LTD handles gas fireplace installations across Trenton, Quinte West, Belleville, Brighton, and surrounding communities. Brandon Johnston personally oversees every job.
Gas fireplaces are one of the most popular home comfort upgrades in Trenton and Quinte West. Unlike wood-burning fireplaces, a gas unit lights instantly, requires no wood storage, produces no ash, and can be controlled with a wall switch or remote. Modern gas fireplace inserts and direct-vent units are also significantly more efficient than older models, making them a practical source of supplemental zone heating for living rooms, master bedrooms, and finished basements.
Johnston Mechanical handles the gas line installation and connection for new fireplace installations. Whether you are installing a new direct-vent gas fireplace in a new home in Quinte West, adding a gas insert to an existing wood-burning fireplace in Belleville, or running a line to a freestanding gas stove in Brighton, Brandon handles the gas side of the job from the existing line to the appliance connection.
Direct-vent gas fireplaces are the most common residential installation. They draw combustion air from outside through a sealed coaxial vent and exhaust directly through the same assembly — no chimney required. This makes them suitable for virtually any room in the house, including rooms on interior walls. Brandon will assess your venting options during the site visit and confirm the best termination location for your specific unit.
Gas line sizing for a fireplace depends on the BTU rating of the unit and the total load on your existing gas system. Brandon checks your meter capacity and main line size before any work begins to confirm the system can handle the additional appliance. If a dedicated line is needed, it will be included in the written quote.
All gas connections are pressure-tested before the fireplace is commissioned. Brandon uses a calibrated gauge to hold the line at test pressure and confirms there are no leaks before the unit is lit for the first time. This is standard practice on every gas job Johnston Mechanical performs.
Gas fireplace installations in Trenton and Quinte West require the gas connection to be made by a TSSA certified technician. The fireplace unit itself may be supplied by the homeowner or a fireplace retailer — Brandon handles the gas line and connection regardless of who supplies the unit.

Frequently Asked Questions
Can I supply my own gas fireplace and have Johnston Mechanical do the gas connection?
Yes. Many homeowners in Trenton and Quinte West purchase their fireplace unit from a retailer and hire Johnston Mechanical for the gas line installation and connection. Brandon handles the gas side of the job regardless of who supplies the unit — just confirm the model and BTU rating before the site visit so he can size the line correctly.
Does a gas fireplace need a chimney?
Not if it is a direct-vent model. Direct-vent gas fireplaces draw combustion air from outside and exhaust through a sealed coaxial vent that terminates through an exterior wall or roof. No chimney is required, which makes them suitable for any room in the house. Brandon will assess your venting options during the site visit.
Can a gas fireplace heat a room in a Trenton winter?
Yes. Most residential gas fireplaces are rated between 20,000 and 40,000 BTU, which is sufficient to heat a living room or open-concept main floor as a primary or supplemental heat source. They are particularly effective as zone heating for rooms that your central furnace has difficulty keeping comfortable during the coldest months.
