Diagnosing a discontinued NTI FTV boiler in Tsawwassen, a peninsula community best known for its ferry terminal and a mix of older and newer housing.

Quick answer
An FTV fault in Tsawwassen usually comes down to ignition, a flame sensor, or a condensate blockage, and since the model is discontinued, the fix depends on whether the part can still be sourced. CANRO checks the fault history and combustion readings first, then gives an honest read on repair versus replace.

Tsawwassen sits on a peninsula within the municipality of Delta, best known outside the area for the BC Ferries terminal, but locally it's a mix of older beachfront-adjacent bungalows built decades ago and newer development like Tsawwassen Springs built more recently on former farmland. FTV units old enough to need repair now generally turn up in the older half of that mix.
A portion of the peninsula also falls under Tsawwassen First Nation treaty lands, which is a separate jurisdiction from the Corporation of Delta -- worth confirming before any permitted repair work, since it affects who issues the permit. CANRO confirms this detail up front rather than assuming every Tsawwassen address falls under the same municipal process.
The FTV is a condensing fire-tube boiler, and the common faults on a unit this age are ignition problems, a weakening flame sensor, and a partially blocked condensate trap. A cracked heat exchanger is less common but usually marks the point where a repair stops being the sensible choice.
Since NTI discontinued the line, some parts now take longer to source, so a fault that used to be a quick fix can now mean a longer wait.
Tsawwassen's sandy, low-lying soil and its exposure to wind coming off the Strait of Georgia mean exterior vent terminations sometimes see more sand and salt-air exposure than a more sheltered inland property would. A technician checks the vent's condition as part of any repair visit with that in mind, particularly on homes closer to the beach in Boundary Bay or English Bluff where salt spray is more constant.
A straightforward ignition, sensor, or condensate fault gets repaired when the part is available -- that's always the starting point. Replacement only enters the conversation once the heat exchanger itself is compromised or a control board for this discontinued line can't be tracked down.
A $90-$150 diagnostic or service-call fee applies and is credited toward the repair. Most FTV repair costs land in the $250-$1,800 range, with the majority closer to $400-$900 once the specific fault is confirmed. These figures are 2026 public-market ballparks, not a quote -- the exact price comes from CANRO's technician after inspecting the unit and confirming which jurisdiction's permit, if any, applies to the fix.
Safety note
If you smell gas, hear hissing near the gas line, or a carbon monoxide alarm goes off, get everyone out of the house right away and call FortisBC at 1-800-663-9911. Don't try to reset the boiler or check the source yourself -- that's a licensed gas fitter's job under Technical Safety BC rules.
It can -- treaty lands are a separate jurisdiction from the Corporation of Delta, so the technician confirms which authority applies before any permitted work.
Exposure to wind and salt air off the strait means vent terminations get checked closely for corrosion or debris during a repair visit.
No -- discontinued only affects future parts availability, not the safety of a unit that's currently working fine.
Less likely -- most units old enough to need this kind of repair are in the peninsula's older, established neighbourhoods.
CANRO schedules diagnostic visits based on current availability; the technician confirms the fault on site before discussing repair options.
