Triangle Tube Boiler Error Codes
A plain-English reference to 9 common Triangle Tube fault codes — what each means, what causes it, and when to call a licensed BC gas technician.
Triangle Tube Prestige boilers (Solo and Excellence) report fault conditions on the control, often as a boiler paired with a Smart Series indirect tank. The stainless design is robust, but ignition, flame, overheat, venting and pressure faults still need correct diagnosis. This reference explains the common Triangle Tube fault conditions and why they call for a licensed BC gas technician.

Triangle Tube error codes — FAQ
Why is my Triangle Tube boiler showing an error code?
Triangle Tube boilers display a fault code when a safety circuit detects a problem — for example with ignition, flame, water flow, temperature or venting. The code points to the affected system. The boiler shuts down to protect itself; a licensed technician then diagnoses the true root cause before repair.
Can I just reset my Triangle Tube boiler?
A single reset after a one-off event is usually fine, but repeated resets without fixing the cause can be unsafe — especially for ignition, gas and venting faults — and can cause further damage. If the code returns, switch the boiler off and call GasBoilers.ca at 604-359-1081.
