Sears 74182, 64182 35 cm, Maximum Length, Exhaust Direction, Exha Listduct L Ocating Dimensions

Exceeding the length of duct pipe or number of elbows allowed in the "MAXIMUM LENGTH" charts can

cause an accumulation of lint in the exhaust system. Plugging

the system could create a fire hazard, aswell as increase drying times.

Do not screen the exhaust ends of the vent

system, nor use any screws, rivets or other fastening means that extend into the duct and catch lint to assemble the

exhaust system. Lint can become caught in the screen, on the screws or rivets, clogging the duct work and creating a fire hazard as well as increasing drying times. Use an approved vent hood to terminate the duct outdoors, and sealall joints with duct tape.

All male duct pipe fittings MUST be installed downstream with the flow of air.

Explosion hazard. Do not install the dryer where gasoline or other flammables are kept or stored. If the dryer is installed in a garage, it must be a minimum of 18 inches (45.7 cm) above the floor. Failure to do so can result in death, explosion, fire or burns.

than 0.75 inches of water column, the system is acceptable. If the manometer reading is higher than 0.75 inches of water column, the system is too restrictive and the installation is unacceptable.

Although vertical orientation of the exhaust system is acceptable, certain extenuating circumstances could affect the performance of the dryer:

•Only the rigid metal duct work should be used.

Venting vertical through a roof may exposethe exhaust system to down drafts causing an increase in vent restriction.

Running the exhaust system through an uninsulated area may cause condensation and faster accumulation of lint.

Compression or crimping of the exhaust system will cause an increase in vent restriction.

The exhaust system should be inspected and cleaned a minimum of every 18 months with normal usage. The more the dryer is used, the more often you should check the exhaust system and vent hood for proper operation.

EXHAUST DIRECTION

All dryers shipped from the factory are set up for rear exhausting. However, on electric dryers, exhausting can be to the right or left side of the cabinet or the bottom of the dryer. On gas dryers, exhausting can be to the right side of the cabinet or the bottom of the dryer. Directional exhausting can be accomplished by installing Exhaust Kit, P/N 131456800, available through your parts distributor. Follow the instructions supplied with the kit.

INSTALL MALE FITTINGS IN CORRECT DIRECTION

In installations where the exhaust system is not described in the charts, the following method must be used to determine if the exhaust system is acceptable:

1.Connect an inclined or digital manometer between the dryer and the point the exhaust connects to the dryer.

2.Set the dryer timer and temperature to air fluff (cool down) and start the dryer.

3.Read the measurement on the manometer.

4.The system back pressure MUSTNOTbe higher than 0.75 inches of water column. If the system back pressure is less

GAS SUPPLY REQUIREMENTS

Replace copper connecting pipe that is not

plastic-coated. Stainless steel or plastic-coated brass MUST be used.

1.Installation MUST conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1 (latest edition).

2.The gas supply line should be of 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 MUSThave an individual shutoff valve.

5.A 1/8 inch (0.32 cm) N.RT. plugged tapping, accessible for test gauge connection, MUST be installed immediately upstream of the gas supply connection to the dryer.

6.The dryer MUSTbe disconnected from the gas supply piping system during any pressure testing of the gas supply piping system at test pressures in excessof 1/2 psig (3.45 kPa).

7.The dryer MUSTbe isolated from the gas supply piping system during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.45 kPa).
