KNOW YOUR VOLTAGE!

|
---|---|---

If you are uncomfortable working with electricity, running electrical supply wire or installing a circuit breaker, please consult a licensed electrician. Make sure power to the heater is turned off at the main disconnect panel whenever doing any work on a heater. Serious injury or electrocution can result from electric shock.

• CHECK YOUR BREAKER! If you’re replacing an existing heater, check the labels of the old heater and use the same voltage.
  **single-pole breaker
  120 volt

double-pole breaker
240 volt
**

WARNING: Connecting a heater to a voltage higher than what’s listed on its rating label will destroy the heater and could start a fire. A heater will not heat properly when connected to a voltage lower than what’s listed on its rating label.

INSTALLATION INSTRUCTIONS

1. All electrical work and materials must comply with the National Electric Code (NEC), the Occupational Safety and Health Act (OSHA), and all state and local codes. Canadian installations must comply with the Canadian Electrical Code (CEC) and provincial codes.
2. Use copper conductors only.
3. DO NOT install the heater directly above bathtub or sink. DO NOT install in shower stall area. Manufacturer recommends a minimum 2 foot (61 cm) clearance to prevent contact with water.
4. DO NOT install the heater in a floor, in a ceiling, below a towel bar, behind a door, or anywhere the air discharge may be blocked in any manner.
5. To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the vicinity of the heater.
6. Connect grounding lead to grounding screw provided. Keep all foreign objects out of heater.
7. CAUTION – High temperature, risk of fire, keep electrical cords, drapery, furnishings and other combustibles at least 3 feet (0.9  m) from the front of the heater and away from the side and rear.

TOOLS REQUIRED

• Wire Strippers

• Wire Connectors

• Straight and Phillips Screwdrivers

• Drill and Drill Bits

• Hammer

• 1½” Wood Screws

A multi-purpose tool or saw to cut toe kick area.

PARTS OF YOUR HEATER

TIPS BEFORE YOU BEGIN

• Verify power has been turned off before starting any work!
• PLACEMENT: For best results, install heater beneath a cabinet in the toe kick area. Install the Under Cabinet Heater (Model UCH) horizontally. Do not install the UCH heater in the floor. Headers and bracing are not necessary.
• WARNING! Vinyl floor manufacturers warn that some vinyl may discolor from temperatures in excess of 110° F (43°C). See your vinyl floor manufacturer for temperature specifications for your vinyl floor covering.
• CONTROLS: A thermostat is required. An electronic wall thermostat is recommended for ultimate control and comfort. An optional field mount thermostat kit is also available, model UCHT.

STEP 1 Determine area of installation

The UCH Series heater REQUIRES A MINIMUM distance of 6 inches (15.2 cm) from adjacent surfaces (see Figure 1). Heaters must be spaced at least 3 feet (0.9 meters) apart.

For installation in an existing wall/cabinet, cut a rough opening 20⅛ inches (51.1 cm) wide by 3½ inches (8.9 cm) high. Opening must be at least 10½ inches (26.7 cm) deep.

STEP 2 Locate or route electrical supply wires

If you have a wall thermostat, route supply wire from circuit breaker to thermostat to rough opening. For models with an optional field mount thermostat kit, route supply wire from circuit breaker to rough opening. Allow enough wire to extend 12 inches (30.5 cm) beyond the opening. Remove four screws from lid and place it aside. Insert supply wire through the hole at the back of the heater and attach it with a cable clamp connector, leaving 6 inches (15.2 cm) wire lead for later use (See Figure 2).

STEP 3 Connect supply wires

Connect the supply ground wire to the green grounding screw provided (See Figure 3).

Note: All wire connections must be made inside the heater (Figure 3).

For 240 volt installation

Connect each supply wire to one heater wire with wire connectors. For 240 or 208 volts, it doesn’t matter which heater wire connects to each supply wire. Both supply wires (black and white) are hot. Wrap supply (white) wire with black tape to identify it as hot.

For 120 volt installation

You’ll need the white wire assembly included with the heater. See Figure 4 for reference to wiring.

1. Attach the two yellow terminals from the white wire assembly to the heating element at spades E and G by pushing the connectors onto the element spades.
2. Cut the black motor wire just below the crimp connector. Connect the short wire from the white wire assembly to the black motor wire with a wire connector.
3. Cut the red motor and red element wires just below their crimp connector to separate them. Wrap the red motor wire end with electrical tape or a wire connector.
4. Cut the white motor and black element wires just below the crimp connector. Connect the white motor wire with the red and black element wires using a wire connector.
5. Wrap the long red lead wire with electrical tape or wire connector.
6. Connect the black lead wire to the black supply wire. Connect the remaining white assembly wire to the white supply wire. If the heater is configured for lower voltage or wattage (see STEP 4), there may only be a black lead wire remaining.
   
   

STEP 4 Set wattage

The heater is shipped ready for 240 volt, 1800 watts. If 900 watts is required, disconnect the yellow terminal from the heating element spade marked D in the wiring diagram. Wrap the disconnected terminal with electrical tape. See Figure 5.

For 120 volt, 1350 watts, disconnect the yellow terminal from the heating element spade marked D in the wiring diagram. Wrap the disconnected terminal with electrical tape. See Figure 4.

For 120 volt, 900 watts, disconnect the yellow terminal from the heating element spade marked D and B in the wiring diagram. The red wire assembly can be removed and discarded.

For 120 volt, 450 watts, complete the step above for 900 watts, then disconnect the yellow terminal from the heating element spade marked C in the wiring diagram. Wrap the disconnected terminal with electrical tape

STEP 5 Install Grille

Reinstall heater lid and attach using four screws provided. Slide heater into opening. Fasten heater to cabinet with screws (not provided) going through the lower holes located on the flanges. See Figure 3. Fasten grille to heater with screws provided going through the upper holes located on the flanges.

Turn power on at the main disconnect panel.

Proceed to OPERATING INSTRUCTIONS.

OPERATING INSTRUCTIONS

1. Make sure all wires are properly connected and installation is complete before you turn on the heater.
2. Do not operate without grille.
3. Do not tamper with the high temperature safety shutoff.

Complete installation

After installation, turn your heater to the highest setting and let it run for 30 minutes. Some smoking may occur as the element initially burns off residue from manufacturing.

If your heater shows signs of overheating, such as glowing red or repeatedly getting unusually hot and shutting off, immediately turn off the circuit breaker and review the “KNOW YOUR VOLTAGE” section or call us.

If the high-temperature safety shutoff trips more than once a day, replace the heater.

How to operate your heater

The room temperature is controlled by a thermostat located either on the wall, or on the heater. Once installation is complete and power is on, follow the steps below for your thermostat.

If you have a wall or built-in thermostat with a knob:

1. Turn the thermostat knob all the way to the right.
2. When the room reaches your comfort level, turn the knob to the left, just until it clicks and the heater turns off. The heater will automatically keep the room temperature around this setting.
3. To reduce the room temperature, turn the knob to the left. To increase the room temperature, turn the knob to the right.

If you have an electronic wall thermostat, follow the instructions in the programming and operating guide included with your thermostat.
