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 built-
in 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.
