OPERATION CHECK
1. After your G Series wall heater has been completely
installed, all thermostats, whether single pole or double pole,
should be turned to LOW or OFF. Turn on breakers or
install fuses. Wait 3 to 5 minutes and check to make sure the
heater is not operating. Should it be operating, disconnect
power and check your wiring. If not operating, turn the
thermostat to the highest position and wait another 3 to 5
minutes. Then check to see that all heaters are operating.
Should it not be operating, again disconnect power and
check your wiring.
2. Allow heater to operate steadily for 1/2 hour.
3. Select the setting for your comfort level.
NOTE: Your electric heating system has many advantages,
one of which is zone or room-by-room control. If you desire to
keep a seldom used room at a lower temperature, this may be
done by lowering the thermostat setting and closing the door.
However, DO NOT try to control different rooms at different temperatures unless the doors are kept closed. This will tend to
increase operating cost and decrease comfort. It is advisable,
if rooms are kept open, that all thermostats have the same setting. By following these instructions you will enjoy greater comfort.
