What to expect from a properly licensed gas fitter for water heater or boiler work in Richmond, including how the city's flat, high-water-table lots affect the job.

Quick answer
Richmond requires a Technical Safety BC licensed gas fitter for any gas water heater or boiler installation, and the work needs a permit and inspection before it's closed in. The licence confirms the fitter has passed provincial testing on gas line sizing, venting, and combustion air specific to that equipment. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450 and works across Richmond's mix of older Steveston-area homes and newer construction on reclaimed delta land.

A Technical Safety BC gas fitter licence is issued by appliance class, and the classes relevant to a house cover water heaters, tankless units, and boilers separately from furnaces. A licensed fitter has been tested on how to size a gas line for the appliance's rated input, how to calculate venting length and termination clearances, and how to confirm the space the equipment sits in has enough combustion air. That's the technical work that determines whether combustion byproducts vent safely outside instead of accumulating indoors.
In Richmond specifically, mechanical rooms are often positioned to account for the city's high water table — utility equipment tends to sit on a raised platform or on the main floor rather than in a low-lying basement, since basements are less common on the delta's flat, low-elevation lots. A licensed fitter accounts for that placement when planning venting and gas line routing, since the path from appliance to exterior wall can differ significantly from a typical basement install.
Any work connecting or reconnecting gas piping for a water heater or boiler in Richmond requires a permit, pulled before the work starts, with an inspection booked once the installation is complete but still accessible for review. This applies even to a straightforward replacement of an existing unit, because the permit requirement is tied to the gas piping being disturbed, not to how routine the swap looks.
Richmond has seen a lot of renovation and rebuild activity in older Steveston-area character homes, where original gas lines sized for a single small appliance sometimes need upsizing when a new tankless unit or boiler with higher input demand goes in. A licensed fitter checks this during the quote stage rather than discovering it mid-installation.
Richmond's low elevation and proximity to the Fraser River mean flood risk is a real consideration when a water heater or boiler is being replaced, not just an afterthought. A licensed fitter will often recommend raising a new gas water heater or boiler on a stand or platform, particularly in homes with mechanical equipment near grade level, to reduce exposure if water intrusion ever happens. This isn't required by code in every case, but it's a practical conversation worth having during installation rather than after a flood event.
| Job type | Licensing scope | Richmond-specific note |
|---|---|---|
| Tank water heater replacement | Line sizing, venting, T&P discharge routing | Often installed on a raised platform given flood exposure |
| Tankless conversion | Gas line upsizing for higher instantaneous draw, condensate drainage | Common in Steveston character home renovations |
| Gas boiler replacement | Boiler licence class, pressure relief, hydronic integration | Newer builds on reclaimed delta land often already have hydronic rough-in |
Safety note
If you ever smell gas, hear a hissing sound near a gas line, or notice soot, a yellow or flickering burner flame, or a pilot light that will not stay lit, leave the house first and call from outside. Then call FortisBC at 1-800-663-9911 to report it. Do not try to relight a pilot or reset anything yourself until the line has been checked. Any work on gas piping, venting, or combustion appliances in BC must be done by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
It's often a practical consideration rather than a strict code requirement — a licensed fitter may recommend a raised platform to reduce flood exposure, particularly for equipment near grade level.
Yes, the permit requirement applies whenever gas piping is disconnected and reconnected, regardless of whether the replacement matches the old system.
Tankless units typically draw more gas instantaneously than a storage tank, so a line sized decades ago for a smaller appliance sometimes can't supply the new unit's peak demand without upgrading.
Boiler work requires a separate licence class beyond standard gas fitting, covering pressure vessels and hydronic heating systems specifically.
Ask for the licence number directly; Technical Safety BC maintains licensing records that can be checked if you want independent confirmation.
An inspector reviews the gas line sizing, connections, venting, and clearances before the installation is closed in behind drywall or insulation, confirming the work meets current code.
