OPERATION OF THE
NORTON IGNITION
SYSTEM
Operation of the Norton Ignition System
Power to the ignition system is 120 volts. It is rated voltage or on higher voltage machines the 120 volts is from a transformer. The ignition system is powered through a timer or coin meter and a thermostat which calls for heat.
The two gas valves are plumbed into a single gas line and both must open before the gas can flow into the burners.
The following diagrams are line to line schematics of the ignition system.
The numbers 4, 7, 3, 9, and letters A and B are terminals on the ignition relay.
FIGURE 1
NORTON IGNITION SYSTEM
Figure 1 (Start of Cycle)
Step #1
a.
The Safety Gas Valve is connected across the lines and opens immediately as soon as a need for heat is indicated by the thermostat.
b.
The Ignition Relay Coil is energized through the normally closed (NC) contacts of the Radiant
Sensor and the NC contacts of the relay. NOTE: Figure 1 shows the electrical circuit of the relay just before it is energized. Figure 2 shows the circuit a moment later.
c.
The igniter is energized through the NC contacts of the Radiant Sensor.
d.
The Operating Gas Valve is connected such that the same 120 volts is applied to both sides of the Gas Valve and the valve stays closed.
Page 8M
FIGURE 2
Operation of the Norton Ignition System
NORTON IGNITION SYSTEM
Figure 2 (Start of Cycle)
Step #2
a.
The Ignition Relay closes now and the Relay Coil stays energized by being powered through the normally open (NO) contacts of the Ignition Relay which close before the NC contacts open.
b.
The operating gas valve still has the 120 volts applied to both sides of the gas valve and the valve stays closed.
Page 9M
FIGURE 3
Operation of the Norton Ignition System
NORTON IGNITION SYSTEM
Figure 3 (About 20 Seconds Later)
Step #3
a.
The Ignition glows red hot, which causes the Radiant Sensor to open its NC Contacts, which deenergizes the Igniter.
b.
As the Radiant Sensor NC Contacts open, the 120 volt to one side of the operating Gas Valve
Coil is removed and an electrical circuit is formed through the NO Contacts of the Ignition
Relay, through the Gas Valve and through the Igniter, and the Gas Valve opens. The relatively low resistance of the Igniter allows nearby full voltage to be applied to the operating Gas Valve and nearby zero voltage to the Igniter and the Igniter is de-energized for all practical purposes.
c.
As the raw gas flows against the red hot Igniter, ignition takes place. The radiant gas flame replaces the radiant glowing of the Igniter and the Radiant Sensor NC Contacts remain open.
Page 10M
IGNITION OPERATION
Operation of the Norton Ignition System
The flame will burn until the thermostat opens the circuit or until the time on the timer or coin meter expires.
The following summarizes the ignition operation:
• Start machine drying cycle.
• Carbide igniter will get red hot.
• Then, gas valve will open.
• The gas burners are ignited by the carbide igniter.
NOTE
SAFETY FEATURES
• Igniter will shut off and burners will remain on during drying cycle.
• Opening tumbler door will cause gas to extinguish. Shut door and gas will not light until flame sensor cools and normal ignition cycle begins.
NOTE
Push “start” switch after door is shut.
• If gas does not light, then the sensor will cool down and restart the ignition cycle.
SAFETY FEATURES
Power Interruptions During Burning of the Gas
Both gas valves are de-energized and the gas is shut off. The Ignition Relay is also de-energized and returns the contacts to the NO and NC positions. Even with resumption of power, the operating gas valve stays closed until the NC contacts of the Radiant Sensor close (about 30 seconds from time of power interruption). A normal ignition cycle begins at this time.
Burner Doesn’t Light Because of Low Voltage or Low Gas Pressure
The operating gas valve will be energized for about 30 seconds and then the
NC contacts of the Radiant Sensor will be closed. 120 volts is applied to both sides of the operating gas valve and it closes to shut off the gas. A normal ignition cycle begins at this time.

Burners will ignite after 12 to 25 seconds.
4.
After flame is burning, Igniter will go out. If both gas valves do not open, then replace.
5.
If Igniter does not go out, then replace Radiant Sensor. If the Radiant Sensor glass is broken, replace it.
6.
Open and close dryer loading door after gas has started burning. When door is closed, gas should not flow until radiant sensor has cooled and Igniter recycles.
INSTRUCTIONS FOR DIRECT IGNITION SYSTEM
OPERATION
1.
Open manual gas valve; handle should be parallel with gas line.
2.
Start machine drying cycle. The igniter will glow red hot; the gas valves will open and the burners will ignite.
CAUTION
3.
The igniter will shut off and the burners will continue burning during heat cycle.
4.
Opening the tumbler loading door will cause the gas to extinguish. Shut the door and the gas will not flow until the flame sensor has cooled. Push the “start” button to begin cycle after door is closed. If ignition fails, wait for five minutes to restart.
5.
To shut off dryer, close the manual gas valve. The handle should be at a right angle to the gas line. Turn off the main electrical supply switch.

NOTE
Troubleshooting
7. Voltage must be identical to what is on the Electrical Rating
Plate. Prevent low voltage; it causes longer drying operation.
8. Back Draft Damper must swing full open to prevent air flow restrictions. (Check for full open operation every 6 months.)
Non-operative or erratic operation of exhaust dampers will cause air flow switches to shut off gas and will result in longer drying time.
NOTE
The above should be checked and corrected before attempting to troubleshoot the Norton
Ignition System.

MAINTENANCE
Maintenance—General
MAINTENANCE
1.
CLEAN LINT TRAP DAILY. Remove lint before starting day’s operation. A clean lint trap will increase the efficiency of the dryer, as the moisture-laden air will be exhausted more quickly.
2.
CLEAN BASKET AND SWEEP SHEETS. Clean periodically and/or as often as required. The basket and sweep sheets are easily accessible by removing the front panel of the dryer.
3.
GEAR REDUCER. Maintain the correct oil level. See separate page on Gear Reducer Operation and Maintenance, for detailed information.
4.
PULLEYS AND BELTS. Keep belts clean. Oil and dirt will shorten the useful life of the belt. Never allow a belt to run against the belt guard. Check periodically for alignment. Pulley shafts must be parallel and the grooves must be aligned. Check and re-tighten pulley set screws periodically. Check belt tension periodically. Lower motor to increase tension by adjusting the nuts fastening the motor plate to the rod connected to the Gear Reducer.
5.
ELECTRIC MOTORS. Keep motors clean and dry. Motors having ball bearings are packed with sufficient grease for approximately five years of normal operation. After five years, the bearings and housing should be cleaned thoroughly. Repack each bearing and the cavity in back of the bearing on-third full with Chevron Grease No. SR1-2.
Motors having wool packed sleeve bearings are oiled at the factory for one year of normal operation. After one year, add annually one-half teaspoon of electric motor oil or S.A.E.#10 to each bearing.
For 24 hour per day operation, add one teaspoon of oil annually.
If motors overheat, check voltage and wiring. Low voltage, inadequate wiring, and loose connections are the main cause of motor failure.

REVERSING CONTROL
TIMER
Dryers with Reversing Control Timer
Instructions
In operation, coasting of basket increases, making it necessary to readjust reversing timer.
CAUTION
Failure to do this will cause the thermal overload units for the basket to cut-out unnecessarily and probably damage the gear reducer.
Adjustment of Reversing Timer Dwell Time
CAUTION
Dryer power supply must be shut off before adjusting timer.
The dwell time is the time from when the motor turns “off”, to when it turns “on” again in the opposite direction.
Turning the dwell adjustment knob counter-clockwise increases the dwell time and turning it clockwise decreases the dwell time.
Recommended dwell time for the basket to stop completely is 5 to 7 seconds. Minimum basket stopping time is
4 seconds.

Ordering Overload Heaters for Overload Relays
ORDERING OVERLOAD
HEATERS FOR
OVERLOAD RELAYS
Properly sized Overload Heaters provide motor protection for the dryer.
Improper heater size may allow the motor to be damaged, or could cause nuisance tripping.
Heater sizes are listed on the Overload Heater Table on page 50. To use the table, refer to the Motor Rating Plate and locate the Full Load Amps (FLA), the
Service Factor (SF), and the Ambient Temperature (Amb.).
Example
Motor Rating Plate show FLA = 3.8, SF = 1.15, and 60 Deg. C Amb.
From the table, heater size is H-25. Order TU267900 - H25.
CAUTION
Overload Relays do not provide protection from short circuits.
Short circuit protection is provided by a device such as a breaker or wall disconnect.

ADDENDUM TO MANUAL4M - NORTON IGNITION SYSTEM
(NOTE: This replaces information about the
24V Direct Spark Ignition System)
OPERATION OF THE
NORTON IGNITION
SYSTEM
FIGURE 1
Power to the ignition system is 120 volts. It is rated voltage or on higher voltage machines the 120 volts is from a transformer. The ignition system is powered through a timer or coin meter and a thermostat which calls for heat.
The two gas valves are plumbed into a single gas line and both must open before the gas can flow into the burners.
The following diagrams are line to line schematics of the ignition system. The numbers 4, 7, 3, 9, and letters A and B are terminals on the ignition relay.
NORTON IGNITION SYSTEM
Figure 1 (Start of Cycle)
Step #1
a .
The Safety Gas Valve is connected across the lines and opens immediately as soon as a need for heat is indicated by the thermostat.
b.
The Ignition Relay Coil is energized through the normally closed (NC) contacts of the Radiant
Sensor and the NC contacts of the relay. NOTE: Figure 1 shows the electrical circuit of the relay just before it is energized. Figure 2 shows the circuit a moment later.
c.
The igniter is energized through the NC contacts of the Radiant Sensor.
d .
The Operating Gas Valve is connected such that the same 120 volts is applied to both sides of the Gas Valve and the valve stays closed.

FIGURE 2
Operation of the Norton Ignition System
NORTON IGNITION SYSTEM
Figure 2 (Start of Cycle)
Step #2
a .
The Ignition Relay closes now and the Relay Coil stays energized by being powered through the normally open (NO) contacts of the Ignition Relay which close before the NC contacts open.
b.
The operating gas valve still has the 120 volts applied to both sides of the gas valve and the valve stays closed.
Page 2A
FIGURE 3
Operation of the Norton Ignition System
NORTON IGNITION SYSTEM
Figure 3 (About 20 Seconds Later)
Step #3
a .
The Ignition glows red hot, which causes the Radiant Sensor to open its NC Contacts, which deenergizes the Igniter.
b.
As the Radiant Sensor NC Contacts open, the 120 volt to one side of the operating Gas Valve
Coil is removed and an electrical circuit is formed through the NO Contacts of the Ignition
Relay, through the Gas Valve and through the Igniter, and the Gas Valve opens. The relatively low resistance of the Igniter allows nearby full voltage to be applied to the operating Gas Valve and nearby zero voltage to the Igniter and the Igniter is de-energized for all practical purposes.
c.
As the raw gas flows against the red hot Igniter, ignition takes place. The radiant gas flame replaces the radiant glowing of the Igniter and the Radiant Sensor NC Contacts remain open.

OPERATION
N O T E
Operation of the Norton Ignition System
The flame will burn until the thermostat opens the circuit or until the time on the timer or coin meter expires.
The following summarizes the ignition operation:
• Start machine drying cycle.
• Carbide igniter will get red hot.
• Then, gas valve will open.
• The gas burners are ignited by the carbide igniter.
SAFETY FEATURES
• Igniter will shut off and burners will remain on during drying cycle.
• Opening tumbler door will cause gas to extinguish. Shut door and gas will not light until flame sensor cools and normal ignition cycle begins.
N O T E
Push “start” switch after door is shut.
• If gas does not light, then the sensor will cool down and restart the ignition cycle.
SAFETY FEATURES
Power Interruptions During Burning of the Gas
Both gas valves are de-energized and the gas is shut off. The
Ignition Relay is also de-energized and returns the contacts to the
NO and NC positions. Even with resumption of power, the operating gas valve stays closed until the NC contacts of the Radiant
Sensor close (about 30 seconds from time of power interruption). A normal ignition cycle begins at this time.
Burner Doesn’t Light Because of Low Voltage or Low Gas
P r e s s u r e
The operating gas valve will be energized for about 30 seconds and then the NC contacts of the Radiant Sensor will be closed. 120 volts is applied to both sides of the operating gas valve and it closes to shut off the gas. A normal ignition cycle begins at this time.

TEST PROCEDURE
TEST PROCEDURE
1.
If igniter does not glow red, disconnect and test with separate 120V. Replace if it does not glow red. If it is damaged or cracked, replace.
2.
Check wiring of ignition system parts per wiring diagram.
3.
Gas valves must be open (click) when dryer is energized.
Burners will ignite after 12 to 25 seconds.
4.
After flame is burning, Igniter will go out. If both gas valves do not open, then replace.
5.
If Igniter does not go out, then replace Radiant Sensor. If the Radiant Sensor glass is broken, replace it.
6.
Open and close dryer loading door after gas has started burning. When door is closed, gas should not flow until radiant sensor has cooled and Igniter recycles.
INSTRUCTIONS FOR
DIRECT IGNITION
SYSTEM OPERATION
INSTRUCTIONS FOR DIRECT IGNITION SYSTEM
OPERATION
1.
Open manual gas valve; handle should be parallel with gas line.
2.
Start machine drying cycle. The igniter will glow red hot; the gas valves will open and the burners will ignite.
CAUTION
3.
The igniter will shut off and the burners will continue burning during heat cycle.
4.
Opening the tumbler loading door will cause the gas to extinguish. Shut the door and the gas will not flow until the flame sensor has cooled. Push the “start” button to begin cycle after door is closed. If ignition fails, wait for five minutes to restart.
5.
To shut off dryer, close the manual gas valve. The handle should be at a right angle to the gas line. Turn off the main electrical supply switch.
CAUTION
Check igniters with 120V before installing on dryer.

CAUTION
Problems with the Norton Ignition System can also be the result of the following:
EXHAUST PIPE SIZE
1 . Exhaust air flow restriction. Exhaust pipe size must
be larger than the exhaust opening. Refer to chart
in manual.
DRYER INLET AIR
DRYER PANELS
GAS PRESSURE
MAIN BURNER
ORIFICE SIZE
2 . Dryer inlet air is a MUST for each unit. It must be 4 to 6 times the combined areas of the dryer exhaust outlet. Refer to chart in manual.
3 . All dryer panels must be in place and on machine for proper operation.
4 . Gas pressure must be 7-9 1/2 inches WC for natural gas and 11 inches WC for propane or butane (bottled) gases.
5 . Refer to chart for correct gas pipe sizes and lengths.
The 3/4 inch gas pipe must be the minimum gas supply pipe for the dryer and over 50 ft., 1 inch pipe size.
6 . Main burner orifices must be correct size. They are calculated with the following information: a . Your locality heating value of gas, BTU/cu. ft.
b . Local specific gravity of gas.
c. Gas manifold pressure inches of WC.
1) 3.5 inches WC pressure for natural gas.
2) 11 inches WC pressure for propane or butane gases.
d . Gas input rate per each burner orifice.

7 . Voltage must be identical to what is on the
Electrical Rating Plate. Prevent low voltage; it causes longer drying operation.
8 . Back Draft Damper must swing full open to prevent air flow restrictions. (Check for full open operation every 6 months.) Non-operative or erratic operation of exhaust dampers will cause air flow switches to shut off gas and will result in longer drying time.
N O T E
The above should be checked and corrected before attempting to troubleshoot the Norton
Ignition System.
