What a Slant/Fin Boiler Warranty Typically Covers

Slant/Fin, like most residential boiler manufacturers, typically separates warranty coverage into parts and heat exchanger terms, with the heat exchanger — the most expensive single component — usually carrying a longer coverage period than general parts and controls. Exact terms vary by model and whether the unit was registered after installation, so we confirm the specific coverage for your unit at the time of service rather than quoting a fixed number here.

Labour for warranty repairs is often NOT included by the manufacturer — that's typically the installing/servicing contractor's responsibility, which is one more reason to work with a licensed contractor who documents installation and maintenance properly from day one.

What Can Void a Slant/Fin Warranty

• Improper installation — incorrect venting, undersized gas supply, or incorrect piping can void coverage even if the unit itself is defective
• Lack of documented annual maintenance — many manufacturers require proof of annual professional service to keep warranty coverage active
• Use of non-approved parts or unlicensed repair work
• Operating the unit outside its rated specifications (oversized or undersized for the application)
• Water quality issues — hard water or improper glycol mixtures in the heating loop can damage the heat exchanger and complicate a warranty claim
• Failure to address a known fault, allowing it to cause secondary damage

How CANRO Helps Protect Your Warranty

When we install a Slant/Fin boiler, we size and vent it to manufacturer spec and Technical Safety BC code, and we provide documentation of the installation. For existing Slant/Fin boilers we service, we keep a maintenance record for you — useful if you ever need to demonstrate the unit was properly maintained for a warranty claim.

Annual maintenance isn't just a warranty checkbox — it's the single best way to catch a failing part before it causes an outage, and it's often the difference between a covered warranty repair and an out-of-warranty bill.

What a Non-Warranty Repair Costs

If a fault isn't covered — either because the warranty has expired or the cause falls outside coverage — every CANRO repair visit still starts with a diagnostic call-out and ends with a free written quote before any work proceeds. We don't quote repair costs over the phone since they depend on the actual fault and parts needed.

Annual Maintenance & Tune-Up

A CANRO tune-up on a Slant/Fin boiler typically includes combustion analysis, heat exchanger and burner inspection, condensate trap service (on condensing models), gas pressure checks, and safety control testing — the same checks that support both warranty compliance and Technical Safety BC gas safety requirements.
