Figure 2. Minimum duct clearance for electric heater applications.
Allow at least 25-inches (610-mm) in front of the control for servicing. For high humidity applications and other important information, see the electric furnace installation instructions Bulletin 30-34.
For limits and set points, see Table 2. For further specifications,
see Table 3. The 15 and 20 kW single phase furnaces contain two supply circuits. Supply wires can be run separately for each circuit, which is the default configuration. Using two supply circuits allows the use of smaller gauge wires. In some cases, it is necessary to use smaller gauge wire to comply with building codes that limit the maximum wire size that can be used for a single circuit. The required wire size for each electric furnace is shown in Table 3. The two circuits can also be joined together with a jumper bar. This is included with all dual circuit furnaces. The jumper bar allows the use of one pair of larger gauge wire, as opposed to two pairs of smaller gauge wire.
Note: Circuit breakers installed in this device are for short-circuit protection of internal wiring and to serve as a service disconnect. Circuit breakers installed within this device DO NOT provide over current protection of the supply wiring.
