The gas supply connection is made to the Tudor's
gas control valve in the middle of the lower rear of
the stove, using a 3/8" male NPT fitting. The supply
line should be ½" diameter, or appropriately sized to
provide a sufficient gas supply to meet the
maximum demand of the unit without undue loss of
pressure. We recommend a flexible line to avoid
undue mechanical load on the valve and to ease
thread alignment, but refer to local codes.

This appliance and its individual shutoff valve must
be disconnected from the gas supply piping system
during any pressure testing of that system at test
pressures in excess of ½ psig. The Tudor must be
isolated from the gas supply piping system by
closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at
test pressures equal to or greater than ½ psig.

Once connected to the gas supply, the supply line
and manifold gas pressures must be tested. The
supply line pressure is tested, to insure it meets the
minimum gas supply pressure as listed in the
Specifications for the type of fuel in use (natural gas
or LP), by connecting a manometer to the supply
line and adjusting
necessary to meet the required supply line pressure
as listed in specifications. The manifold pressure tap
on the gas control valve, refer to
