The following are specific require-
ments for proper and safe operation of
your dryer.
WARNING
FIRE HAZARD
Failure to follow these instructions can cre-
ate excessive drying times and fire hazards.
WARNING
FIRE HAZARD
• Failure to follow safety warnings ex-
actly could result in serious injury,
death, or property damage.
• DO NOT install a booster fan in dryer
exhaust duct.
• Install all clothes dryers in accor-
dance with the installation instruc-
tions in this manual.
Gas supply requirements, con-
tinued
2. The gas supply line should be 1/2 inch
(1.27 cm) pipe.
3. If codes allow, flexible metal tubing
may be used to connect your dryer to
the gas supply line. The tubing MUST
be constructed of stainless steel or
plastic-coated brass.
4. The gas supply line MUST have an
individual shutoff valve installed in ac-
cordance with the B149.1, Natural Gas
and Propane Installation Code.
5. A 1/8 inch (0.32 cm) N.P.T. plugged
tapping, accessible for test gauge con-
nection, MUST be installed immediately
upstream of the gas supply connection
to the dryer.
6. The dryer MUST be disconnected from
the gas supply piping system during
any pressure testing of the gas supply
piping system at test pressures in
excess of 1/2 psig (3.45 kPa).
7. The dryer MUST be isolated from the
gas supply piping system during any
pressure testing of the gas supply pip-
ing system at test pressures equal to or
less than 1/2 psig (3.45 kPa).
8. Connections for the gas supply must
comply with the Standard for Connec-
tors for Gas Appliances, ANSI Z21.24/
CSA 6.10.
Use only 4 inch (102 mm) diameter
(minimum) rigid or semi rigid metal duct
and approved vent hood which has a
swing-out damper(s) that open when
the dryer is in operation. When the dryer
stops, the dampers automatically close to
prevent drafts and the entrance of insects
and rodents. To avoid restricting the outlet,
maintain a minimum of 12 inches (30.5
cm) clearance between the vent hood and
the ground or any other obstruction.
WARNING
FIRE HAZARD
DO NOT
install a clothes dryer with
flexible plastic or foil venting materials.
Flexible venting materials are known to
collapse, be easily crushed and trap lint.
These conditions will obstruct clothes
dryer airflow and increase the risk of fire.
If your present system is made up of
plastic or foil duct, replace it with a
rigid or semi-rigid metal duct. Ensure
the present duct is free of any lint
prior to installing dryer duct.
