A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping
is provided on the inlet and outlet side of the gas
control for a test gauge connection to measure the
manifold pressure.
The fireplace and its individual shut-off valve must be
disconnected from the gas supply piping system
during any pressure testing of the system at test
pressures in excess of one-half (1/2) psig (3.5 kPa).
The fireplace must be isolated from the gas supply
piping system by closing its individual shut-off valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than one-half
(1/2) psig (3.5 kPa).
