How much does it cost to convert a propane fireplace to natural gas in Calgary?

Converting a propane fireplace to natural gas in Calgary typically costs $300-$800 for the conversion kit and labour, plus $800-$2,500 for running a new natural gas line from your meter to the fireplace location. The total project cost ranges from $1,100-$3,300 depending on the distance of the gas line run and complexity of the installation.

The conversion process involves two main components. First, your existing propane fireplace needs a natural gas conversion kit, which includes new burner orifices, gas valve spring, and regulator components designed for natural gas's lower pressure (7" water column versus propane's 11" water column). Most quality fireplace manufacturers like Napoleon, Regency, and Heat & Glo offer factory conversion kits for $150-$400. The labour to install the conversion kit typically runs $150-$400 and must be performed by a licensed gas fitter.

The bigger expense is usually the natural gas line installation. If your home already has ATCO Gas service but no existing gas line near the fireplace, you'll need a new branch line run from your gas meter or an existing gas appliance. Gas line installation costs $15-$25 per linear foot for basic runs, but can reach $35-$50 per foot if the route requires going through finished walls, around obstacles, or under concrete slabs. A typical 30-50 foot run from the basement gas meter to a main floor fireplace costs $800-$1,500 in labour and materials.

Calgary's widespread ATCO Gas availability makes this conversion financially attractive. Natural gas currently costs approximately $3.50-$5.00 per GJ compared to propane at $25-$35 per GJ delivered in Calgary. For a fireplace that operates 3-4 hours daily during Calgary's six-month heating season, switching from propane to natural gas saves $400-$800 annually in fuel costs. The conversion typically pays for itself within 2-3 years through lower operating costs.

Every natural gas conversion requires a gas permit from the City of Calgary and inspection by a Safety Codes Officer. The gas line work must be performed by a licensed gas fitter who will obtain the permit (typically $100-$200) and ensure the installation meets Alberta Building Code requirements. The inspector verifies proper gas pressures, leak testing, and combustion air supply before approving the conversion.

Not all propane fireplaces can be converted to natural gas. Check your owner's manual or the rating plate inside the fireplace to confirm a conversion kit is available. Some older or budget-model fireplaces were designed exclusively for propane and cannot be safely converted. Additionally, if your propane fireplace is vent-free, converting it to natural gas may require upgrading to a direct-vent system depending on room size and ventilation requirements under current Alberta Building Code standards.

The conversion work must be done by a licensed gas fitter — never attempt this as a DIY project. Incorrect gas pressures, improper orifice sizing, or faulty connections can cause incomplete combustion, carbon monoxide production, or gas leaks. A qualified gas fitter will pressure-test the system, verify proper flame characteristics, and ensure the fireplace operates safely on natural gas.
