THERMOSTAT INSTALLATION

Refer to FIGURE 2

NOTE: The thermostat control circuit must be wired prior to the wiring of the heater unit.

This heater may be thermostatically controlled by either a line voltage wall-mounted thermostat (Model 86W), or an optional builtin thermostat accessory kit (Model 90). Model 90 thermostat kits are designed for easy installation with this heater. Instructions for installing thermostats are provided below and are also supplied with each thermostat kit.

OPTIONAL LINE VOLTAGE WALL-MOUNT THERMOSTAT

1.Locate thermostat on an inside wall away from all drafts and approximately 4-5 feet above the floor.

2.Route all wiring through the thermostat first and then to the heater.

OPTIONAL (MODEL 90) UNIT-MOUNT THERMOSTAT Refer to FIGURE 3

1.Remove the top cover from the heater.

2.Remove the 5/8” knockout located on the left side of the front panel (use a screwdriver to remove the knockout). Also remove the two plastic hole plugs (see illustration).

3.Install thermostat from back side of front panel and fasten in place, from front, with two screws and washers provided (see illustrations).

4.Attach temperature control knob by gently pushing it on to the thermostat shaft. Flats on shaft and knob must line up for proper installation (do not force control knob onto shaft).

5.Remove black wire from thermal fuse and attach it to thermo- stat terminal marked “4”.

6.Remove white wire from temperature limit terminal marked “1” (Note: the other end of this wire is attached to incoming field wiring) and attach it to the thermostat terminal marked “1”.

7.Attach black thermostat wire to thermal fuse and white ther- mostat wire to the temperature limited marked “3”.

INSTALL THE HEATER
