2. Safety Information
Read all safety warnings and instructions carefully before installing or operating the heater. Failure to follow these instructions may result in fire, explosion, electric shock, property damage, or personal injury.
- Ventilation: Ensure adequate ventilation in the installation area. Never operate the heater in an enclosed space without proper exhaust ventilation to prevent carbon monoxide buildup.
- Fuel Handling: Use only diesel fuel. Do not use gasoline or other volatile fuels. Handle fuel in a well-ventilated area away from ignition sources.
- Exhaust System: The exhaust pipe must be routed outside the vehicle/cabin and away from combustible materials. Ensure all connections are sealed to prevent exhaust gas leakage into the heated space.
- Electrical Connections: All electrical connections must be secure and correctly wired according to the provided diagrams. Ensure the power supply matches the heater's voltage requirements (24V DC).
- Clearances: Maintain sufficient clearance around the heater and its air inlets/outlets to prevent overheating and ensure proper airflow. Do not block air intake or exhaust.
- Flammable Materials: Keep flammable materials, liquids, and vapors away from the heater.
- Children and Pets: Keep children and pets away from the heater during operation.

- Exhaust and Intake Tubing: Connect the intake tubing to the heater's air intake and the exhaust tubing to the heater's exhaust port. Route both tubes outside the vehicle/cabin, ensuring the exhaust is directed away from any openings and combustible materials. Secure tubing with clamps.
- Electrical Wiring: Connect the wiring harness to the heater unit, fuel pump, and digital controller. Connect the main power wires to a 24V DC power source, observing correct polarity. Ensure all electrical connections are secure and protected.
- Air Duct Installation: Attach the 1m air duct to the heater's hot air outlet and route it to the desired heating area. Install the air register at the end of the duct.
5. Operating Instructions
The Bison 2200A heater features a programmable digital controller for easy operation and temperature management. It offers multiple operating modes to suit various heating needs.
5.1 Digital Controller
The digital controller allows you to set the desired temperature, select operating modes, and monitor the heater's status. Refer to the controller's specific user guide for detailed button functions and menu navigation.
5.2 Operating Modes
- Automatic Regulation: In this mode, the heater automatically adjusts its heat output to maintain a user-defined temperature range (adjustable from 41°F to 95°F or 5°C to 35°C).
- Constant Heat Output Selection: This mode allows manual selection of a constant heat output level, from minimum to maximum, regardless of the ambient temperature.
- Air Circulation/Ventilation: This is a fan-only mode that circulates air without generating heat. Useful for ventilation purposes.
5.3 Mobile App Control
The Bison 2200A can also be controlled via a mobile application, offering seamless climate control from your smartphone. Download the General Components app from the App Store or Google Play.
