3. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your HCALORY HBU1S Diesel Air Heater. The heater can be installed in either a vertical or horizontal position.
Installation Steps:
- Mounting: Securely mount the heater to a stable surface using the provided mounting plate and hardware. Ensure adequate clearance around the unit for airflow and maintenance.
- Electrical Connections: Connect the main power cable to a 12V or 24V battery system. Ensure correct polarity (red to positive, black to negative). The system includes a fuse for protection.
- Fuel System: Connect the fuel pump to the heater and the fuel line to the fuel tank. Ensure all fuel line connections are tight and free of leaks. The fuel filter should be installed between the fuel pump and the fuel tank.
- Air Intake and Exhaust: Connect the air intake hose and exhaust pipe to their respective ports on the heater. The exhaust pipe must be routed outside the heated space to prevent exhaust fumes from entering. Secure connections with hose clamps.
- Hot Air Ducting: Attach the hot air outlet ducting to the heater's hot air port. Additional venting connectors (like a T-connector) may be used to distribute heat to multiple areas.

6. Troubleshooting
This section addresses common issues you might encounter with your diesel heater.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not start | Low battery voltage, no fuel, clogged fuel line/filter, faulty glow plug. | Check battery charge, refill fuel tank, inspect and clean/replace fuel components, check glow plug. |
| Error Code E032 | Ignition plug short circuit (faulty glow plug or control board). | Inspect and replace the glow plug. If the issue persists, the control board may need replacement. |
| Insufficient heat output | Low power setting, blocked air intake/exhaust, incorrect altitude mode. | Increase power setting, clear blockages, ensure correct altitude mode is selected. |
| Excessive smoke | Poor fuel quality, incorrect air-fuel mixture, carbon buildup. | Use high-quality diesel, check altitude settings, perform maintenance to clear carbon buildup. |
