(NSCNGPIC), CSA B149.1.
Wear safety glasses and work gloves. Have a fire extinguisher
available during start--up, adjustment procedures, and service
calls.
Recognize safety information. This is the safety--alert symbol
. When you see this symbol on the furnace and in instructions
or manuals, be alert to the potential for personal injury.
