15. ATION Refer to Figure 3 Exhausting of the dryer s should be planned and constructed so that no air restrictions occur Any restriction due to pipe size or type of installation can cause slow drying time excessive heat and lint in the room From an operational standpoint incorrect or inadequate exhausting can cause a cycling of the high limit thermostat which shuts off the main burners and results in inefficient drying The exhaust duct connection near the top of the dryer will accept an 8 200 mm round duct Individual exhausting of the dryers is recommended All heat moisture and lint should be exhausted outside by attaching a pipe of the proper diameter to the dryer adapter collars and extending it out through an outside wall This pipe must be very smooth on the inside as rough surfaces tend to collect lint which will eventually clog the duct and prevent the dryer from exhausting properly All elbows must be smooth on the inside All joints must be made so the exhaust end of one pipe is inside the next one downstream The addition of an exhaust pipe tends to reduce the amount of air the blower can exhaust This does not affect the dryer operation if held within practical limits For the most efficient operation it is recommended that no more than 14 ft 4 25 m of straight 8 in diameter pipe with two right angle elbows be used for each cylinder Maintain a minimum of 1 25mm clearance between duct and combustible material 8514
