Possible Causes

Drafts or negative pressure in room, Dirty pilot orifice, Misaligned pilot flame, Inadequate combustion air

How to Fix / Troubleshooting

Safety: Turn gas control to OFF and wait several minutes before relighting. Ensure area is free of flammable vapors.

Steps:

  • Clean pilot: Remove and clean the pilot orifice with compressed air. Ensure a strong, steady flame.
  • Shield from drafts: Check for open windows, exhaust fans, or HVAC returns that may pull air across the pilot. Correct airflow issues or install a draft shield if recommended by Bradford White.
  • Check combustion air: Ensure the heater has adequate combustion air openings per code.

If the pilot still will not stay lit, the thermopile or gas control valve may be failing and should be tested and replaced as needed.
