3. Safety Information
Operating a diesel heater involves combustion and electrical components. Adhere to all safety guidelines to prevent injury or damage.
- Ventilation: Ensure adequate ventilation for the heater's combustion air intake and exhaust. Never operate the heater in an enclosed, unventilated space.
- Exhaust: The exhaust gases contain carbon monoxide, which is odorless and deadly. Always route the exhaust pipe securely to the outside, away from any air intakes or windows.
- Fuel: Use only diesel fuel. Handle fuel with care, away from open flames or ignition sources. Ensure all fuel connections are leak-free.
- Electrical: Connect the heater to a stable 12-volt DC power source with appropriate fusing. Incorrect wiring can cause electrical fires or damage to the unit.
- Mounting: Mount the heater securely to a stable, non-combustible surface. Maintain adequate clearance from flammable materials.
- Children and Pets: Keep children and pets away from the heater during operation, as surfaces can become hot.
- Maintenance: Perform regular maintenance as described in this manual. Do not attempt repairs beyond your technical capability.
4. Installation
Proper installation is crucial for the safe and efficient operation of your Planar 2D heater. While installation can be straightforward, professional installation is recommended if you are unsure about any steps.
4.1. Planning the Installation
- Location: Choose a dry, protected location for the heater unit, ensuring sufficient space for air circulation and access for maintenance. Consider the routing of fuel lines, exhaust, intake, and hot air ducts.
- Mounting Surface: The mounting surface must be robust enough to support the heater's weight and vibrations. Use the provided mounting plate and hardware.
- Clearances: Maintain minimum clearances around the heater from combustible materials as specified in the technical drawings.

4.2. Step-by-Step Installation Guide
- Mount the Heater: Secure the main heater unit to the chosen surface using the mounting plate and hardware. Ensure it is level and stable.
- Install Fuel System:
- Connect the fuel pump to the vehicle's fuel tank or a dedicated fuel tank (not included).
- Route the fuel line from the tank to the fuel pump, and then from the fuel pump to the heater unit. Ensure all connections are tight and leak-free.
- Mount the fuel pump securely, typically at an angle to allow air bubbles to escape.
- Connect Electrical System:
- Connect the main power harness to a fused 12-volt DC power source (e.g., vehicle battery). Ensure proper polarity.
- Connect the control panel wiring harness to the heater unit and mount the control panel in an accessible location.
- Install Air Intake and Exhaust:
- Attach the air intake pipe to the heater and route it to a clean air source, away from exhaust fumes.
- Attach the exhaust pipe to the heater and route it securely to the outside, ensuring it is clear of any obstructions and directed away from living spaces or air intakes.
- Install Hot Air Ducting:
- Connect the hot air ducting to the heater's hot air outlet.
- Route the ducting to the area you wish to heat and install the air outlet vent.
- Final Checks: Double-check all connections (fuel, electrical, air, exhaust) for security and leaks. Ensure no wires or pipes are pinched or exposed to excessive heat.
5. Operating Instructions
Once installed, operating your Planar 2D heater is straightforward using the control panel.
Figure 5.1: The digital control panel (e.g., PU-5, PU-16, or PU-22) used to operate the Planar 2D heater, featuring a display and control buttons.
5.1. Initial Startup (Priming)
Before the first use, or after running out of fuel, the fuel system needs to be primed to remove air. This is typically done through a specific function on the control panel or by repeatedly attempting to start the heater until fuel reaches the combustion chamber. Refer to your specific control panel's manual for detailed priming instructions.
5.2. Basic Operation
- Power On: Press the power button on the control panel. The display will illuminate.
- Set Temperature/Power: Use the up/down arrows or rotary knob (depending on control panel model) to set the desired temperature or heating power level.
- Heating Cycle: The heater will initiate its startup sequence, which includes pre-heating, fuel injection, ignition, and fan operation. This process may take a few minutes.
- Power Off: To turn off the heater, press the power button again. The heater will enter a cool-down cycle to prevent overheating, during which the fan will continue to run for a few minutes before shutting down completely. Do not disconnect power during the cool-down cycle.
Note on Temperature Display: The control unit typically displays temperature in Celsius. There may not be an option to switch to Fahrenheit.
6. Maintenance
Regular maintenance ensures the longevity and efficient performance of your Planar 2D heater.
- Visual Inspection (Monthly): Check all fuel lines, electrical connections, and air ducts for signs of wear, damage, or leaks. Ensure the exhaust pipe is clear and securely fastened.
- Clean Air Intake: Ensure the air intake for combustion is free from dust, debris, or obstructions.
- Clean Exhaust Outlet: Periodically check and clean the exhaust outlet to prevent carbon buildup, which can restrict airflow and affect performance.
- Fuel Filter: If your installation includes an inline fuel filter, inspect and replace it as recommended by the filter manufacturer.
- Battery Voltage: Ensure your 12V power source maintains adequate voltage, especially during startup, as low voltage can prevent ignition.
7. Troubleshooting
This section addresses common issues you might encounter with your Planar 2D heater.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater does not start/ignite | Low fuel level, air in fuel line, low battery voltage, clogged fuel filter, faulty glow plug. | Check fuel level, prime fuel system, check battery voltage, replace fuel filter, inspect glow plug (professional service recommended). |
| Heater produces white smoke | Incomplete combustion, low fuel pressure, incorrect air/fuel mixture, faulty glow plug. | Check fuel supply, ensure proper voltage, clean air intake/exhaust, professional inspection. |
| Heater produces black smoke | Excessive fuel, restricted air intake, clogged exhaust. | Check air intake for obstructions, clean exhaust, ensure correct fuel pump operation. |
| Heater shuts down unexpectedly | Overheating, low voltage, fuel supply interruption, error code. | Check for obstructions around heater, ensure proper ventilation, check battery/power supply, check control panel for error codes. |
| Control panel displays error code | Specific fault detected by the heater's diagnostic system. | Refer to your specific control panel's manual for a list of error codes and their meanings. |
If you are unable to resolve an issue, contact a qualified technician or the seller for assistance.
