Troubleshooting
Likely causes
What to check
Inspect the photocell lens, draw a fuel sample from the tank bottom, and check the nozzle size against the commissioning sheet.
When to call us
After two lockouts in a week — repeated resets risk an unburnt-fuel firebox explosion.
Likely causes
What to check
Take a flue gas analysis — high CO with low excess O2 confirms incomplete combustion.
When to call us
Immediately: sooting fouls tubes fast, cuts efficiency and creates an air quality compliance issue.
Likely causes
What to check
Log flue gas temperature — a rise of 20 °C over baseline usually means roughly 1% efficiency lost.
When to call us
Book a clean and combustion tune; the fuel saving normally covers the service cost.
FAQ
Yes — including fuel heating and viscosity control, steam-traced lines, HFO burners and the extra fireside cleaning frequency that HFO demands.
Often yes. A dual-fuel burner lets you switch between gas and diesel by price or supply security. We assess the boiler shell, furnace rating and controls before quoting.
Diesel-fired plant typically every 6 months; HFO plant every 3 months or sooner, driven by flue gas temperature rise rather than the calendar.
