3)
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 that allows for easy opening and closing.
Do not block access to the shut-off valve. The valve is necessary
for turning the gas to the appliance on or off.
4)
The regulator must be checked
at a minimum water column of
at least 1” (2.5 cm) above the
set pressure. The inlet pressure
to the regulator should be as
follows for operation and
monitoring of the regulator
setting:
- NATURAL GAS: manifold
pressure 4” W.C. Supply
pressure 3.5”-10.5” W.C.
- LP GAS: manifold pressure of
11” W.C. Supply pressure 8.0”
- 13” W.C.
5)
Line pressure testing: Testing above 112 PSI (3.5 kPa), with water column of 14” (35.6 cm) (gauge).
The cooktop 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).
Testing below 112 PSI (3.5 kPa) with a water column of 14” (35.6 cm) (gauge) or lower.
The cooktop 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).
