The supply line must be fitted with an approved shut-off valve.
This valve should be located in the same room as the range and
should be in a location where it can be easily opened and
closed.
Do not block access to the shut-off valve. The valve is necessary

pressure to the regulator should
4)
be as follows for operation and
checking the regulator setting:
- NATURAL GAS: manifold
pressure 4" W.C.P. Incoming
line pressure 3.5"-10.5" W.C.P.
- LP GAS: manifold pressure
11" W.C.P.
pressure 8.0"-13" W.C.P.
Line pressure testing: Testing above 112 PSI (3.5 kPa), with 14" W.C.P. (35.6 cm) (gauge).
The range and its individual shut-off valve must be disconnected from the gas supply piping system
during any pressure testing of that system at test pressures greater than 1/2 psig (3.5 kPa).
5)
Testing below 112 PSI (3.5 kPa) with 14" W.C.P. (35.6 cm) (gauge) or lower.
The range must be isolated from the gas supply piping system by closing the respective manual shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).
