Test gauge connections are provided on the front of the millivolt and electronic gas control valve (identified IN for the
inlet and OUT for the manifold side). The control valves have a 3/8” (10 mm) NPT thread inlet and outlet side of the
valve (
Figure 1
and
Figure 2
).

Propane tanks are at pressures that will cause damage to valve components. Verify that the tanks have step down
regulators to reduce the pressure to safe levels.
The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures
in excess of
1/2 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its equipment shutoff valve during
any pressure testing of the gas supply piping system at test pressures
equal to or less than
1/2 psi (3.5 kPa).
