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 9.5 mm (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 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 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 natural gas valve spud orifice size
must be reduced to ensure complete combustion. Refer
to Table 1 and Table 2.
