The efficiency rating of this appliance is a product
thermal efficiency rating determined under continuous
operating conditions and was determined independently
of any installed system.
The appliance and its shutoff valves must be disconnected
from the gas supply piping system during any pressure
testing where the pressure exceeds ½ PSIG (3.45 KPa)
or damage will occur to the valve.
The appliance must be isolated from the gas supply
piping system by closing its individual manual shutoff
valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than ½ psig (3.45 KPa).
Always check for gas leaks with a soap and water solution after completing the required
pressure test.
TO TEST VALVE PRESSURES
The pressure taps are located on the left side of the valve
• Turn set screw 1 turn counter clockwise to loosen,
• Place
