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 EXHAUST DUCT L OCATING DIMENSION5 4 3/8" ¢m) GAS SUPPLY REQUfREMENTS 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 The system back pressure MUST NOT be higher than 0,75 inches of water column If the system back pressure is less than 075 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 plastic-coated. used. Replace copper connecting pipe that is not Stainless steel or plastic-coated brass MUST be 1 Installation MUST conform with local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z2231 (latest edition) or in Canada, the current CAN/CGA B149 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 MUSTbe constructed of stainless steel or plastic-coated brass 4 The gas supply, line MUST have an individual shutoff valve, S A 1/8 inch (0.32 cm) N.PT plugged tapping, accessible for test gauge connection, 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 piping system at test pressures equal to or less than 1/2 psig (3,45 kPa)
