Info

The drum is the same as in the electric dryer, except it does not have a heat baffle on it. Airflow gas dryers: The airflow in gas dryers is similar to electric dryers except for the heat source and the rear of the drum. The air enters the cavity through the louvered opening in the right rear corner of the dryer. The air is pulled across the gas burner, through the burner chamber and is ducted to the rear of the drum. Airflow problems: Airflow problems are usually caused by restrictions, leaks or short unrestricted vents resulting in longer drying times, hotter dryer surfaces and in extreme cases causing the thermal limiter to open on electric dryers. Restrictions: Restrictions can occur any place in the airflow system, but the most common are: 1. Installing the dryer in a small inclosed area; such as a closet without a louvered door that reduces the intake air. 2. Fan problems caused by either a slow running motor, a broken or deformed fan blade or a deformed fan housing. 3. A lint restriction in the lint screen area. The operator may not be cleaning the lint screen before using. 4. A restriction in the exhaust system in the building caused by the design of the vent, such as; the diameter of the vent pipe being too small, too long, too many right angles, or a collapsed or lint restricted vent pipe. Note: Problems caused by the vent pipe in the building are not covered under the product warranty. 34
Air leaks: Two types of air leaks may occur: 1. Air being drawn in around the door opening, between the drum and the front panel, or around the foam seal between the front duct and the blower housing, replaceing some of the air being drawn through the drum and lowers the efficiencyof the dryer. Note: With short direct vent runs; such as you have when the dryer is installed against an outside wall, use a 2 1/2” vent cap rather than a 4” vent cap. Electrical Operation (Electric Dryers Models) Note: Always refer to the wiring diagram or schematic with the product. Note: An air leak that occurs around the door opening or between the drum and the front panel usually will cause lint to build up on the inner panel of the door. When the dryer is connected to electrical power, line 1 is connected to switches A and B of the accumulator (timer). Line 2 is connected to the second centrifugal switch of the drive motor. 2. Air being pushed out around the blower housing or vent pipe inside the dryer, allows some of the moisture that has been removed from the clothes to be recirculated. Short unrestricted vents: The venting system in the dryer is designed to operate under some back pressure. This back pressure is needed to slow the airflow and allow the air to be heated before it passes through the clothes. Accumulator (Timer)Circuits: Line 1 is applied to switches A and B of the accumulator. When a coin slide is pushed in and released, the accumulator closes the contacts of switches A and B. The contacts of switch A remain closed for the complete cycle. The contacts of switch B open about five minutes before the end of the cycle to allow the dryer to cool down. With the contacts of switch A closed, power is applied to the timer motor, thermal limiter, indicator light and drive motor.
