Why Choose Fireplace Installation
Gas Fireplace Options
Modern gas fireplaces are a far cry from the pilot-light-driven units of decades past. Today's models offer realistic flames, high heat output, precise temperature control, and a variety of design styles that complement any interior. QC Mechanical installs both traditional and contemporary gas fireplaces from Heat n Glo and Montigo. Heat n Glo fireplaces are known for their innovative designs and wide range of styles, from classic log sets to sleek linear models. Many Heat n Glo units feature IntelliFire ignition systems for easy, reliable starts and True Flame technology for the most realistic-looking fire available. Montigo specializes in custom and linear fireplace designs that serve as dramatic architectural focal points, with options for see-through, corner, and extra-long installations. Gas fireplaces provide more than ambiance — they deliver real supplemental heat. A quality gas fireplace can heat a large living space efficiently, reducing demand on your primary HVAC system during the shoulder seasons when running the full heating system is unnecessary. With thermostat or remote control, you can dial in exactly the warmth you want.

Installation: What Is Involved
Gas fireplace installation requires expertise in gas line work, venting, framing, and finish carpentry. QC Mechanical handles the mechanical scope of the installation — gas supply, venting through the wall or roof, electrical connections, and unit setup — ensuring everything meets local building codes and manufacturer specifications. Direct-vent fireplaces are the most common configuration for Pacific Northwest installations. These units draw combustion air from outside and exhaust through a concentric vent pipe, making them safe and efficient for tight, well-insulated homes. The vent can run horizontally through an exterior wall or vertically through the roof, depending on the installation location and building design. For existing homes, we evaluate the proposed installation location, determine the most practical venting route, verify gas supply capacity, and confirm that the structure can support the fireplace and any required framing. For new construction, we coordinate with the builder to ensure rough-in is completed at the right phase of the project.
- Gas line sizing, routing, and connection
- Direct vent, B-vent, and power vent configurations
- Framing and fire-stop installation per code requirements
- Electrical connection for ignition, blower, and controls
- Coordination with builders on new construction projects

Site Evaluation
Our technician assesses the proposed installation location, determines the best venting route, checks gas supply capacity, and identifies any structural considerations.
Detailed Proposal
You receive a written proposal covering the fireplace unit, gas line work, venting, electrical, and installation labor. We outline what is included and what finish work may be needed.
Gas and Vent Rough-In
We run the gas line, install venting through the wall or roof, and complete any required framing or fire-stop work before the fireplace unit is set.
Fireplace Installation
The fireplace unit is set in place, connected to gas and venting, wired for ignition and controls, and tested for proper operation and safety.
Final Inspection and Walkthrough
We verify gas pressure, combustion performance, and venting operation. We walk you through the controls, maintenance requirements, and warranty coverage.

Fireplace Installation — Frequently Asked Questions
Direct vent fireplaces use a sealed combustion chamber and draw outside air for burning, then exhaust through a concentric vent pipe. They are the safest and most efficient option. B-vent fireplaces draw combustion air from inside the room and vent upward through a vertical chimney. Direct vent is the most common choice for Pacific Northwest installations.
Yes. Direct vent gas fireplaces can vent horizontally through an exterior wall, so no chimney is required. This makes gas fireplace installation practical for virtually any room with an exterior wall.
Both. Modern gas fireplaces produce significant heat output — many models deliver 20,000 to 40,000+ BTUs, enough to heat a large room. They provide genuine supplemental heating while also creating ambiance. Blower fans distribute heat more effectively into the room.
We are an authorized dealer and installer for Heat n Glo and Montigo gas fireplaces. Both brands offer a wide range of styles, sizes, and features to suit any home and design preference.
Most gas fireplace installations take one to two days for the mechanical work — gas line, venting, unit installation, and testing. Finish work (mantels, surrounds, tile or stone) is typically completed separately and the timeline depends on the complexity of the design.
In most jurisdictions in King, Pierce, Kitsap, and Thurston counties, a mechanical permit is required for gas fireplace installation. QC Mechanical handles the permitting process for you.
Yes. A gas fireplace insert can be installed into an existing masonry fireplace, converting it from wood-burning to gas operation. This improves efficiency, eliminates the need for firewood, and provides push-button convenience.
Gas fireplaces require relatively little maintenance. An annual inspection of the burner, logs or media, glass, and venting system is recommended to ensure safe and efficient operation. We offer annual fireplace inspections as part of our service offerings.
