If the exhaust pipe passes through a wall, a metal sleeve of slightly larger diameter should be set in the wall and the exhaust pipe passed through this sleeve. This practice is required by some local codes and is recommended in all cases to protect the wall. This type of installation should have a means provid- ed to prevent rain and high winds from entering the exhaust when the dryer is not in use.

DRYER IGNITION (SOLID STATE IGNITION). The solid state ignition system lights the main burner gas by spark. The gas is ignited and burns only when the gas-valve relay (in the electronic controller) calls for heat. The procedure for first-time starting of a dryer is as follows: A.
Page 25
TOUCH PAD DESCRIPTION INDICATOR LIGHTS (L.E.D.s) Description Cycle (1 through 5) These L.E.D.s are on solid when a particular cycle is chosen for operation or programming. Gas Valve This L.E.D. is part of the 4-digit numeric display and will be on solid during the drying part of a cycle when the gas valve does not need to be on.
Page 26
This touch pad switch will stop the dryer during a dry cycle without clear ing the present drying cycle if pressed once. If pressed and released twice, consecutively, the present dry cycle will be cleared. STOP This touch pad switch will start the operation of a dry cycle if pressed and released once.
Page 27
OPERATING INSTRUCTIONS To dry a load of items, you must choose one of the five-programmed dry cycles. Each of these five dry cycles may be modified in two different ways to match your load. Please, refer to the “Permanent Reversing Dryer Controller Programming”...
Page 28
During the dry cycle, either pressing the STOP touch pad switch on the dryer controller or opening the dryer loading door will stop the dry cycle and not clear it. If you press the STOP touch pad switch on the controller and then open the dryer loading door, the dry cycle will not be cleared.
Page 29
TEMPORARY REVERSINGDRYER CONTROLLER PROGRAMMING Temporary programming mode will allow the change of the stored dry cycle settings in the dryer controller for one complete dry cycle. After the dry cycle is complete, the default settings that existed be- fore the temporary change are restored. The temporary dry cycle can be stopped and cleared at any time during the dry cycle operation.
Page 30
Press and release the SELECT/ENTER touch pad switch on the dryer controller. Once the SELECT/ENTER touch pad switch is pressed and released, the dry time L.E.D. will switch off, the dry cycle L.E.D. and programming L.E.D. will remain on, the temperature L.E.D.
Page 31
TEMPORARY REVERSING DRYER CONTROLLER PROGRAMMING EXAMPLE REQUIREMENTS: Dry a load with 40 minutes of actual heat at 185°F and five minutes of cool down. The following procedure will show you how to temporarily modify the existing dry cycle 5 program for one cycle of drying.
Page 32
PERMANENT REVERSING DRYER CONTROLLER PROGRAMMING The permanent programming mode will allow the change of the stored dry cycle settings in the dryer controller until the operator physically changes them again. The factory default settings can be restored in the dryer controller by pressing the default settings push-button on the back (component) side of the dryer controller circuit board.
Page 33
Press and release either the UP or DOWN touch pad switch of the dryer controller to change the drying temperature. Each press and release of either the UP or DOWN touch pad switch will either increase or decrease, respectively, the temperature by five degrees Fahren- heit or three degrees Celsius, depending on how your dryer controller is set up.
Page 34
PERMANENT REVERSING DRYER CONTROLLER PROGRAMMING EXAMPLE REQUIREMENTS: Dry a load with 50 minutes of actual heat at 195°F and three minutes of cool down. The following procedure will show you how to permanently modify the existing dry cycle 5 pro- gram for one cycle of drying.

Electronic Ignition Module This machine uses an electronic spark ignition system to directly light the burners. The electronic ignition module (gray box) is located inside the rear control box. The red wire from the transformer provides 24 VAC through the 1.5 amp fuse and into the module to operate the entire direct ignition system.
Page 53
Spark Electrode Assembly-Function Step 1: The spark electrode and sensing electrodes are located directly at the side of the burner housing. Step 2: The electrode with the black hi-voltage wire conducts the spark to the center grounding probe, directly over the burner. Step 3: The electrode with the black sensing wire detects ignition and monitors flame by signaling the module.
