FURNACE CONNECTION

The furnace is shipped fully wired except for the connections to the house wiring. The furnace power
connections are made in a junction box inside the blower compartment. The junction box contains a BLACK
wire to be connected with L1 (hot), a WHITE wire to be connected with L2 (Neutral), and a GREEN wire to be
connected to the ground.
NOTE
Use good quality wire nuts such as Marrette®
connectors, Ideal® wire nuts, etc.
If the junction box must be moved from it's original location to the other side of the unit.
1. Remove the appropriate plastic cap from the desired left or right side panel, and place it on the panel not
being serviced.
2. Fasten the junction box to the selected panel.
3. Secure power line connection into junction box, following above reference.
4. Use only ground screws for junction enclosure.
THIS FURNACE IS EQUIPPED WITH A BLOWER DOOR SAFETY SWITCH. DO NOT
DISABLE THIS SWITCH. FAILURE TO FOLLOW THIS WARNING CAN RESULT IN
ELECTRICAL SHOCK, PERSONAL INJURY, OR LOSS OF LIFE.

15.0 LOW VOLTAGE WIRING

The thermostat and control wiring should be a minimum of 18 AWG copper. Excessive lengths of wire may
result in enough voltage drop to impair the proper functioning of the furnace. For thermostat wires in excess of
25 feet (7.6m), use 16 AWG; 50 feet (15.2m), use 14 AWG.

SINGLE STAGE THERMOSTAT

The automatic heat staging option allows a single stage thermostat to be used with a two stage furnace. The
control provides a movable jumper (P5) to select between 5 minute and *10 minute automatic staging. Auto-
matic staging time begins when the blower is energized after the heat blower delay period. If the jumper is in
the 5 minute position, the control will automatically start high heat after 5 minutes of continuous low heat op-
eration. If the jumper is in the *10 minute position, the control will automatically start high heat after 10 minutes
of continuous low heat operation. Once high heat is started from automatic staging, the demand for high heat
remains until the heat call is satisfi ed.
Adjust Thermostat Heat Anticipator Mechanical thermostat:
Set thermostat heat anticipator to match the amp draw of the electrical components in the R--W circuit.
Accurate amp draw readings can be obtained at the wires normally connected to thermostat subbase
terminals R and W. The thermostat anticipator should NOT be in the circuit while measuring current.
1. Remove thermostat from subbase or from wall.
2. Connect an amp meter across the R and W subbase terminals or R and W wires at wall.
3. Record amp draw across terminals when furnace is in low heat and after blower starts.
4. Set heat anticipator on thermostat per thermostat instructions and install on subbase or wall.
The board and gas valve in a Wolf Steel furnace have an amp draw of .9 amps.
If using an Electronic thermostat: Set cycle rate for 3-4 cycles per hr.
IMPORTANT:
USE COPPER CONDUCTORS ONLY.
