Furnace ignites with a loud bang or pop, sometimes shaking the flue or burner door.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect ignition electrode position on Viadrus burner, Low primary air setting, Excessive gas pressure at burner, Dirty burner ports

Inspect electrode: Check the ignition electrode gap and position relative to the burner head as per the Viadrus burner manual. Adjust carefully.
Clean burner: Remove and clean the burner head and ports to ensure even gas distribution.
Check gas pressure and air: A gas technician must measure burner gas pressure and adjust the gas valve and air shutter to achieve proper combustion and safe ignition.
