yellow flame means fuel is not being burned completely and CO
may be present. Keep the blower door on the furnace closed.
Use vents or fans when they are available on all fuel-burning
appliances. Make sure appliances are vented to the outside. Do
not grill or barbecue indoors, or in garages or on screen porches.
• Check for exhaust backflow from CO sources. Check the draft
hood on an operating furnace for a backdraft. Look for cracks
on furnace heat exchangers.
• Check the house or garage on the other side of shared wall.
• Keep windows and doors open slightly. If you suspect that CO
is escaping into your home, open a window or a door. Opening
windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read
this manual in its entirety, and make sure you understand what to
do if your CO Alarm sounds.
