Maintenance Requirements

Annually (qualified service person)

  • Inspect the exhaust venting and vent termination for blockages, damage, or flue gas leaks.
  • Verify that the exhaust connector is in place, slopes up away from the furnace, and is free of holes, damage, or corrosion.
  • Inspect all wiring and connectors.
  • Inspect the heat exchanger/s and fan blower for corrosion, deterioration, or debris.
  • Verify that the return air ducting is physically sound, fully sealed to the furnace cabinet, and terminates outside the space that contains the furnace.
  • Verify that the physical support of the furnace is sound, with no sagging, cracks, or gaps around the base so as to provide a seal between the support and the base of the furnace.
  • Verify that there is no obvious signs of deterioration or damage to the furnace.
  • Verify that the pilot and burner flames are in good condition, and adjust if needed.
  • Clean and test the flame sensor.
  • All installer-supplied air filters should be cleaned, or replaced.

If the inspections reveal any damaged components, they must be replaced prior to placing the boiler back into operation.
