WIRING & CONTROLS
BASIC WIRING AND CONTROLS:
The WinterGreen Furnace has been pre-wired at the factory for 115 volt, 60-cycle operation. The unit
comes equipped with a power cord that just needs to be plugged into a receptacle. We recommend that
you use 20 amp receptacle dedicated only to the furnace. This receptacle should have a circuit protec-
tion device.
The furnace has several basic operating components:
DO NOT PLUG THE FURNACE IN BEFORE INSTALLATION IS
COMPLETE.
MODIFICATIONS TO FURNACE WIRING WITHOUT THE EXPRESS
WRITTEN PERMISSION OF WINTERGREEN WILL VOID THE WAR-
RANTY. USE A QUALIFIED ELECTRICIAN TO PERFORM ANY
TROUBLESHOOTING OR REPAIRS O THE ELECTRICAL CIRCUIT.
ANY EXTERNAL WIRING FOR THE FURNACE MUST BE 16 GAUGE,
AWG COPPER, 105˚ DEGREE CELCIUS METAL CABLE.
NEVER UNPLUG THE FURNACE DURING NORMAL OPERATION,
AN OVERFIRING AND UNSAFE CONDITION WILL RESULT.

Temperature
Controller
Displays the operating temperature of the furnace, controls the furnace temperature
and Thermal Spike Protection circuit.
Temperature
Probe
Senses the operating temperature of the furnace and sends to Temperature
Controller.
Flow Switch
Detects a “no fluid flow” condition in the system and closes the furnace damper. A
“System Alert” indicator light will glow on the control panel
(See Figure 2 – Con-
trol Panel)
indicating a problem has occurred. After the problem has been cor-
rected the light will go out.
Solenoid Valve
(Zone Valve)
If so equipped) The solenoid controls fluid flow to a “Thermal Protection” zone. This
device should be connected to Terminal “1” on the terminal block inside the control
panel. (
See Figure 1 – WinterGreen Furnace Electrical Schematic
Circulating
Pump
C
ontinuously runs as long as the furnace is plugged into a receptacle. The pump
circulates fluid from the furnace throughout the system.
Draft Inducer
Should operate continuously (If required) as long as there is a fire in the furnace or
when the loading door is opened for refueling to reduce smoke spillage into the
room. It is controlled by the on/off switch located on the operator’s panel.
(See Fig-
ure 2 – Control Panel)
The Draft Inducer is mounted remote from the furnace on
the chimney flue. (
See the “Draft Inducer”
section in this manual for proper loca-
tion.)
Damper
Actuator
(Draft Door)
Operates fully open when there is a call for heat or fully closed to extinguish the fire.
It is controlled by the temperature controller.
The actuator can be turned off in
cases of a Runaway Fire by a
switch on the control panel, in all other oper-
ating conditions the actuator should always be left in the “ON” position.
