Follow wiring diagram. If heater is wired direct, use the built-in thermostat for temperature control. OPTIONAL WIRING CONVERSIONS When using a separate wall control, simply turn the heater's built- in thermostat to its highest setting. There is no need to disconnect the built-in thermostat: a) Turn built-in thermostat to highest setting. b) Remove knob. c) Fasten security cover to grille. LINE-VOLTAGE THERMOSTAT Refer to FIGURE 7 If wall-mounted control is desired, use the Model 86W Line-Volt age Thermostat. Purchase thermostat separately. Cut blue wire. Strip .” of insulation from each end. Connect wires from wall control to each stripped wire. LOW-VOLTAGE THERMOSTAT If wall-mounted control is desired, use a Model 82 Transfomer/ Relay with an appropriate low-voltage thermostat (purchase separately). Follow the mounting and wiring instructions packed with the controls. HALF-WATTAGE CONVERSION Refer to FIGURE 8 The heater will produce less heat and use less electricity if converted to half-wattage. Remove the black jumper wire from the heating element and discard wire.

Install housing mask. A housing mask has been provided to keep construction dust, drywall spray, paint, etc., from damaging the heater. Bend the flap on the mask and push it into the heater housing. NOTE: Mask can be put into place before or after heater assembly is reinstalled. Remove mask before operation. 2. Reinstall heater assembly. Secure heater assembly to housing with four (4) screws. Check thermal overload button marked "RESET". Heater will not operate unless this button is depressed. Refer to FIGURE 9 3. Install grille. Place grille over heater and attach with four (4) screws. Push knob onto thermostat stem. 4. Attach security cover to grille (optional). When heater is installed in a public area without a separate wall control, it is recommended that: a) Built-in thermostat be set to desired temperature level. b) Thermostat knob be removed. c) Security cover be attached to grille with two (2) screws, pro vided. 5. Check operation. Turn on power at service entrance. Turn thermostat to its highest setting and make sure heating element and blower come on. Then turn it to its lowest setting and make sure element and blower shut off. NOTE: The fan delay prevents the fan from coming on until the element is hot. Likewise, it keeps the fan running until the element cools down. USE AND CARE CAUTION – DISCONNECT POWER AT SERVICE ENTRANCE AND LOCK OUT PANEL BEFORE CLEANING OR SERVICING UNIT. Thermal Overload Protector Your heater is equipped with a manual-reset thermal overload protector. If heater fails to operate when thermostat is turned to its highest setting: 1) Turn off power at service entrance. 2) Remove knob and grille. 3) Press button marked "RESET". This type of device is particularly useful (compared to automatic reset devices) because it encourages the user to find and correct the cause of overheating unit when resetting the protector. To avoid property damage when using this heater to prevent freeze- ups: Make sure heater functions properly before leaving unattended. A tripped protector will prevent the heater from operating. Cleaning Clean the heater using the round brush tool on your vacuum cleaner. Remove large accumulatoins of dust, lint, etc., that might impede the flow of air through the heater. Such blockage will lower its efficiency and create a possible overheating condition. To clean grille, use a soft cloth which has been moistened with household window cleaner. CAUTION – METALAND ELECTRICAL PARTS SHOULD NEVER BE IMMERSED IN WATER.
