New Stainless Steel Flexible Connector –
Use only if allowed by local codes
(Use Design AGA Certified Connector)
NOTE: When connecting gas supply line, a
pressure test point must be installed downstream
from the shut-off valve for checking inlet gas
pressure.
5. The gas line to your laundry room should be
made of black iron pipe. A 3/8 in. pipe with
an inside diameter of 11.7 mm (.46 in.) will be
adequate if length of supply line is not over 6 m
(20 ft.). If length exceeds this, use 12.7 mm
(1/2 in.) pipe. If copper semi-rigid tubing is used
it must be internally tinned or equivalently
treated to resist sulfur corrosion.
NOTE: Each dryer and its individual shut-off valve
must be disconnected from the gas supply piping
system during any pressure testing of that system
at test pressures in excess of 3.45 kPa (1/2 psi).
6. Check all pipe connections (internal and
external) for gas leaks with a soapy solution.
Gas connections should be checked annually
for leakage.
7. Be sure the shut-off valve in each dryer is OPEN.
Each dryer is shipped with the valve open.
8. The dryer gas valve is equipped with a pressure
test point for checking manifold pressure.

For proper operation at altitudes above 610 m
(2000 ft.) the gas valve spud orifice size must be
reduced to ensure complete combustion. Refer to
