How to Fix / Troubleshooting
Safety: If you smell combustion gases or suspect carbon monoxide, turn off the boiler, ventilate the area, and leave the space. Do not operate the boiler until inspected.
- Step 1 – Visual vent inspection: Check all vent and intake joints on the Triangle Tube boiler for gaps, loose clamps, or disconnected sections. Do not run the boiler with venting compromised.
- Step 2 – Outdoor terminations: Ensure the exhaust and intake terminations are clear of obstructions.
- Step 3 – Do not attempt combustion adjustments: Gas and air settings require specialized tools.
- Professional service required: A licensed technician must perform a combustion analysis, inspect the burner and heat exchanger, and repair or replace any damaged vent components.
