NOTE: When connecting gas supply line, a
pressure test point must be installed downstream
from the shutoff valve for checking inlet gas
pressure.
5. The gas line to your laundry room should be
made of black iron pipe. A 3/8 inch pipe with an
inside diameter of 11.7 mm (0.46 inch) will be
adequate if length of supply line is not over 6 m
(20 feet). If length exceeds this, use 12.7 mm
(1/2 inch) pipe. If copper semi-rigid tubing is
used it must be internally tinned or equivalently
treated to resist sulfur corrosion.
NOTE: The dryer and its individual gas 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 psig).
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 your dryer is OPEN.
Your 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 760 m
(2500 feet) the gas valve spud orifice size must be
reduced to ensure complete combustion. Refer to

accumulation of combustion gases, DO NOT
exhaust dryer air into a window well, gas
vent, chimney or enclosed, unventilated
area, such as an attic, wall, ceiling, crawl
space under a building or concealed space
of a building.
