Whirlpool 8577213C Venting Requirements, Gas Supply Pressure Testing, Vent System Length

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 exhaust must not be connected into any gas vent, chimney, wall, ceiling, attic, crawlspace, or a concealed space of a building.

Only rigid or flexible metal duct shall be used for exhausting.

Do not use an exhaust hood with a magnetic latch.

Do not install flexible metal vent in enclosed walls, ceilings, or floors.

4" (102 mm) heavy metal vent and clamps must be used.

Use clamps to seal all joints. Do not use duct tape, screws, or other fastening devices that extend into the interior of the vent. Items sticking through the vent can catch lint.

The total length of flexible metal vent shall not exceed 73/4 ft (2.4 m).

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" (305 mm) from the ground or any object that may be in the path of the exhaust (such as flowers, rocks or bushes).

If using an existing vent system, clean lint from the entire length of the system and make sure exhaust hood is not plugged with lint. Replace any plastic or metal foil vent with rigid metal or flexible metal vent.

Plan installation to use the fewest number of elbows and turns.

AB

Exhaust Air Flow

A.Better

B.Good

Allow as much room as possible when using elbows or making turns. Bend vent gradually to avoid kinking.

Vent outlet is located at the center of the bottom dryer back.

The vent can be routed up, down, left, right, behind the dryer or straight out the back of the dryer.

Vent System Length

Maximum length of vent system depends upon the type of vent used, number of elbows and type of exhaust hood. The maximum length for both rigid and flexible vent is shown in the chart.
