[_ CHECKFOR LEAKS
When all connections have been made, make
sure all cooktop controls are in the OFF position
and turn on the main gas supply valve. Use a
liquid leak detector at all joints and connections
to check for leaks in the system.
CAUTION: DO NOT USE A FLAME TO
CHECK FOR GAS LEAKS.
I
When using test pressures greater than 1/2 psig
to pressure test the gas supply system of the
residence, disconnect the cooktop and individual
shut-off valve from the gas supply piping. When
using test pressures of 1/2 psig or less to test the
gas supply system, simply isolate the cooktop from
the gas supply system by closing the individual
shut-off valve.

(B) Yellow tips on
