Gas heaters – the warning signs

Heaters should be checked immediately if any of the following warning signs are present:
  • a yellow or sooty flame (rather than sharp and blue) except in a decorative log fire;
  • a pilot light which extinguishes unexpectedly or “pops” when lighting;
  • signs of heat damage such as discoloration of walls or heater panels;
  • soot stains around the heater; and
  • walls which are too hot to touch when the heater is operating.
