Gas Supply Line
Recommended method
■Provide a gas supply line of ¹⁄₂" rigid (IPS) pipe to the dryer location. Pipe joint compounds that resist the action of LP gas must be used. Do not use TEFLON®† tape. With LP gas, piping or tubing size can be ¹⁄₂" minimum. Usually, LP gas suppliers determine the size and materials used in the system.
Alternate method
■The gas supply may also be connected using ³⁄₈" approved copper or aluminum tubing. If the total length of the supply line is more than 20 feet (6.1 m), larger tubing will be required. If using natural gas, do not use copper tubing. Pipe joint compounds that resist the action of LP gas must be used.
Flexible metal appliance connector:
■It is recommended that a new flexible stainless steel gas line,
■Do not kink or damage the flexible stainless steel gas line when moving the dryer.
Rigid pipe connection:
The rigid pipe connection requires a combination of pipe fittings to obtain an
■Must include a shutoff valve:
The supply line must be equipped with a manual shutoff valve installed within 6 ft. (1.8 m) of dryer in accordance with National Fuel Gas Code, ANSI Z223.1. In Canada, an individual manual shutoff valve must be installed in accordance with the B149 installation codes CAN/CGA
B149.1 and CAN/CGA B149.2. This valve should be located in the same room as the dryer. It should be in a location that allows ease of opening and closing. Do not block access to shutoff valve. The valve is for turning on or shutting off gas to the dryer.

■Installed in a confined area:
If the dryer is installed in a confined area such as a bathroom or closet, provision must be made for enough air for combustion and ventilation. Check governing codes and ordinances or refer to the “Recessed Area and Closet Installation Instructions” in the “Location Requirements” section.
Gas Supply Pressure Testing
A ¹⁄₈" NPT minimum plugged tapping, accessible for gauge testing, must be installed immediately upstream of the gas supply connection to the dryer.
The dryer must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of ¹⁄₂ psig.
Venting Requirements
WARNING
Fire Hazard
Use a heavy metal vent.
Do not use a plastic vent.
Do not use a metal foil vent.
Failure to follow these instructions can result in death or fire.
WARNING: To reduce the risk of fire, this dryer MUST BE EXHAUSTED OUTDOORS.
■The dryer vent must not be connected into any gas vent, chimney, wall, ceiling, or a concealed space of a building.
■Do not use an exhaust hood with a magnetic latch.
■Do not install flexible metal vent in enclosed walls, ceilings or floors.
■4" (10.2 cm) heavy metal vent and clamps must be used.
■Use clamps to seal all joints. Vent must not be connected or secured with screws or other fastening devices which extend into the interior of the vent. Do not use duct tape.
IMPORTANT: Observe all governing codes and ordinances.
Use a heavy metal vent. Do not use plastic or metal foil vent.
Rigid metal vent is recommended to prevent crushing and kinking.
Flexible metal vent must be fully extended and supported when the dryer is in its final position. Remove excess flexible metal vent to avoid sagging and kinking that may result in reduced airflow and poor performance.
An exhaust hood should cap the vent to prevent rodents and insects from entering the home or business.
Exhaust hood must be at least 12" (30.5 cm) from the ground or any object that may be in the path of the exhaust (such as flowers, rocks or bushes).
