NOTE: Accessories described in this instruction manual are
intended for use with Marley Engineered Products 1800, 1900,
2500, 2600, C1800 and C2500 Series Model C baseboard
heaters only.
INSTALLATION
NOTE: It is recommended that no more than one thermostat
be used in each room (or area).
1. The thermostat can be installed in either end of the heater
that the power wiring is brought into.
2. Remove selected wiring compartment cover (Figure 1)
and discard.
3. If the thermostat is controlling more than one heater, the
total of all heater amperage ratings (Table 1) cannot
exceed 22 amps at 120 volts AC thru 277 volts AC, 15.5
amps at 347 volts AC or 10 amps at 600 volts AC, Refer to
Table 2 for correct wire, circuit breaker, or fuse sizing.
4. Connect thermostat to baseboard heater and power wiring
per wiring diagram using properly sized listed wire nuts.
5. Fold wires back into wiring compartment making sure bare
ground wire does not contact terminals of thermostat and
install the thermostat assembly in place of the discarded
compartment cover.
6. Reconnect power at main fuse or circuit breaker
distribution panel.
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.
