OPERATION CHECK

1. After your electric baseboard heating system has been completely installed, all thermostats, whether mounted on the wall or in the baseboard, should be turned to LOW or NO HEAT. Then turn on breakers or install fuses. Wait 3 to 5 minutes and check to see that none of the heaters are operating. Should any of the heaters be operating, disconnect power and check your wiring. If none are operating then turn the thermostats to the highest position and wait another 3 to 5 minutes. Then check to see that all heaters are in operation. Should any not be operating, again disconnect power and check your wiring.
2. Allow entire system to operate steadily for 1/2 hour. This should remove all residue from manufacturing. (Some smoking may occur).
3. Select the setting for your comfort on all thermostats.
4. 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.
