another heater, it is easier for the power supply connections to be made prior
to the installation of the heater(s) to the wall. If this is not possible, connections may be made through the opening in the junction boxes when the front cover(s)
is removed. See Figure 8.

2.After the baseboard system has been completely installed, all thermostats should be turned to LOW or NO HEAT setting. Then turn on breakers or install fuses. Wait 3 to 5 minutes and check to see that none of the heaters are oper- ating. If operating, disconnect power and check wiring. If none are operating then turn the thermostats to highest setting and wait 3 to 5 minutes. Check to see that all heaters are operating. Should any not be operating, disconnect power and check wiring.
3.Allow entire system to operate steadily for
4.Select the setting for comfort on all thermostats.
5.To clean heater: Because of the convection heating principle which depends upon circulation of air through the finned element, dust particles will periodical-
ly be deposited between the fins and should be removed occasionally for max- imum efficiency of the heater. A vacuum cleaner with proper attachments can easily be worked along the top and bottom of the finned element to clear it of dust deposits.
NOTE: The painted finish of the heater may be cleaned with a slightly damp cloth if desired. Do not use wax cleaners or polishes as these waxes may vaporize when the heater is in operation and cause discoloration.
