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).
Step 9. Wiring the Fireplace
