WARNING! Installation must be performed by qualified HVAC technician. Improper installation can cause fire hazard or equipment damage.

Electrical Connections

Follow all electrical codes and safety procedures.

Disconnect power at main breaker before beginning work.
Connect line voltage wiring (L1, L2, Ground) to furnace terminal block.
Connect low voltage thermostat wiring (R, W, G, C) to control board.
Verify proper voltage and polarity before energizing.

CAUTION! Electrical shock hazard. Always verify power is disconnected with voltage tester.

Controls and Operation

Furnace operation is controlled by thermostat and internal sequencer.

Normal Operation: Thermostat calls for heat, sequencer energizes heating elements in stages, blower activates after heat buildup.

Blower Speed Selection: Adjust blower speed taps for proper airflow. Control Board: Monitors safety circuits and controls sequencing. Limit Switches: Automatically shut off power if overheating occurs. Transformer: Steps down voltage for control circuit (24V).

Thermostat Wiring

Standard 4-wire thermostat connection:

R (Red) - 24V Power
W (White) - Heat Call
G (Green) - Fan Control
C (Blue/Black) - Common

Tip: Use 18-gauge thermostat wire and ensure proper polarity.

Maintenance Procedures

Regular maintenance ensures efficient and safe operation.

Monthly: Check and replace air filter if dirty.
Seasonal: Inspect heating elements for damage or corrosion.
Annual: Clean blower wheel and motor; check electrical connections.
Biannual: Verify safety switch operation and calibrate thermostat.

WARNING! Disconnect power before performing any maintenance. Heating elements remain hot after shutdown.

Safety Features

Multiple safety systems protect against overheating and electrical hazards.

High Limit Switch: Cuts power if temperature exceeds safe limits. Door Safety Switch: Disables power when access panel is removed. Thermal Fuses: Non-resettable protection against extreme temperatures. Sequencer Timing: Prevents simultaneous element activation.

Cleaning & Care

Keep furnace clean for optimal performance and safety.

Exterior: Wipe with dry cloth only. Interior: Vacuum dust and debris annually. Heating Elements: Clean with soft brush when cool. Blower: Remove and clean blower wheel as needed.

CAUTION! Never use water or liquid cleaners on electrical components.
