water heater flame adjustment
My 30 year old Atwood water heater needs to have the flame adjusted. It burns yellow with a bit of blue, it emits soot from the heater door whenever it is running, and it smells bad when lit. My problem is this...The screw that holds the air intake adjustment seems to be an 1/8 hex screw. I have been to many stores and can't find an 1/8 inch socket. PB Blaster, needle nose pliers, channel locks, nothing will grab the small screw head and I am afraid of distorting the screw head with repeated attempts to loosen it. Does anyone know where can get a socket wrench so small, or would drilling the screw out be an alternative?
