Overview
Self-Powering Mobile Diesel Heater for Off-Grid Heat
The YeloDeer Self-Powering Mobile Diesel Heater is a portable diesel heating solution designed for off-grid, outdoor, mobile, and temporary heating needs.
It uses diesel combustion to create heat and thermoelectric generation technology to convert heat into electrical energy after stable combustion is achieved. This helps the heater support its own operation once running steadily, reducing the need for continuous external power during normal use.

Important Safety Information Before Ordering
This is a diesel combustion heater. Exhaust gas must always be routed safely outdoors.
Never allow exhaust gas to enter a tent, RV, vehicle cabin, boat cabin, shelter, temporary structure, or any occupied space.
If the heater is used with a sealed space or vehicle cabin, a proper wall-through or tent exhaust adapter may be required to channel all exhaust gases outside the living space. Do not use the heater in any setup where exhaust cannot be safely discharged outdoors.
Power & Startup Notes
The heater requires its internal batteries for initial ignition.
Before startup, make sure the batteries are installed correctly.
After powering on, check the LCD voltage display.
If the voltage is below 15.0V, charge the battery to 15.0V–16.8V before starting the heater.
If the standard charger is not available, a cigarette lighter cable may be connected to the DC input interface to assist startup from a vehicle cigarette lighter port or portable power station.
After the heater has started and operated stably for at least 5 minutes, the external cigarette lighter cable can be unplugged.

Features & Benefits
Self-Powering Diesel Heat
This heater is built for mobile and off-grid heating. It uses diesel combustion to generate heat and thermoelectric generation technology to convert part of that heat into electrical energy after stable combustion is reached.
Built-In Battery Startup
The heater uses internal batteries to provide the initial power required for ignition.
Before operation, insert the batteries into the battery compartment and match the positive (+) and negative (-) indicators correctly.
Generates Power After Stable Combustion
Once the heater has fired up and operated stably, the internal thermoelectric module helps supply the operational current needed for normal running.
This reduces dependence on continuous external power once the heater is operating properly.
1–4kW Adjustable Heat Output
Choose from 9 heat levels to match your space, insulation, outdoor temperature, altitude, ventilation, and comfort needs.
Heat Output Range: 1–4kW
Heat Levels: 1–9
Fuel Consumption: 0.1–0.48L/h
Fuel Tank Capacity: 4.5L
Diesel Only Fuel System
This heater is designed for diesel fuel only.
Do not use gasoline, alcohol, kerosene, mixed fuels, or other unapproved flammable liquids.
Portable All-in-One Design
The heater is designed as a portable mobile heating system with an integrated fuel tank, battery startup system, heating structure, control panel, and air inlet / outlet connections.
It is suitable for field operations, outdoor activities, camping, emergency backup heat, vehicles, boats, tents, and temporary structures.
Exterior Placement Option
If the heater is positioned outside the area intended for heating, attach the air inlet and air outlet pipes to guide airflow properly.
Slide the insulation sleeve onto the air outlet pipe to help reduce heat loss.
Safety-Focused Exhaust Setup
The exhaust pipe assembly must be installed securely.
All exhaust gas must be discharged outside the living or occupied space.
If using the heater with a sealed space or vehicle cabin, a proper wall-through or tent exhaust adapter may be required to safely channel exhaust outdoors.

Setup, Safety & FAQ
Setup Before Use
Step 1: Battery Installation
Insert the batteries into the battery compartment before operation.
Match the positive (+) and negative (-) indicators correctly.
The heater requires battery power for initial ignition.
Step 2: Exhaust Pipe Assembly
Install the exhaust pipe assembly securely before startup.
Make sure all exhaust connections are tight.
The exhaust elbow should be locked into the heater’s exhaust interface.
Install the muffler and exhaust pipes according to the instruction manual.
Slide the protective heat sleeve over the exhaust assembly where required.
Always route exhaust gas outdoors.
Step 3: Air Inlet & Outlet Pipes
If the heater is positioned outside the area intended for heating, connect the air inlet and air outlet pipes.
Rotate the pipe connectors clockwise to lock them into place.

Operation Notes
Power On: Press the power button to connect power. The LCD backlight will illuminate.
Ignition: Start the heater according to the instruction manual. The “ON” indicator will flash during startup.
Power Adjustment: Use the up or down buttons to adjust the power level.
Minimum Level: 1
Maximum Level: 9
Powering Off
Turn off the heater according to the instruction manual. The “OFF” indicator will flash.
After shutdown, the internal components remain extremely hot. The system fan will automatically run for an additional 3 to 5 minutes to dissipate heat safely.
Do not disconnect power, move, or pack the unit until the fan completely stops and the LCD screen turns off.
Battery & Voltage Notes
The internal batteries provide the initial power needed for stable ignition.
After turning on the main power, check the LCD voltage display.
If the voltage is below 15.0V, charge the battery to 15.0V–16.8V before starting.
If the standard charger is unavailable, a cigarette lighter cable can be connected to the DC input interface to draw power from a vehicle cigarette lighter port or portable power station for startup support.
After the heater has fired up and operated stably for at least 5 minutes, the external cigarette lighter cable can be unplugged.
Safety Precautions
Use diesel fuel only.
Check the fuel level regularly during use.
Always shut down the heater before refueling.
Stop operation immediately if any fuel leakage is detected.
Keep surrounding objects away from high-temperature areas of the heater.
Do not operate the heater where flammable vapors, gases, or dense combustible dust may accumulate.
Adult supervision is required when the heater is operated near children.
Never allow exhaust gas to enter any occupied space.
Do not modify the heater or use non-approved parts.
FAQ
1. Does this heater need external power?
The heater needs battery power for initial ignition. After stable combustion is achieved, the internal thermoelectric module helps supply the operational current needed for normal running.
2. Can I start it if the battery voltage is low?
If the LCD voltage display is below 15.0V, charge the battery to 15.0V–16.8V before startup. A cigarette lighter cable may also be used through the DC input interface for startup support when the standard charger is unavailable.
3. When can I unplug the external cigarette lighter cable?
After the heater has started and operated stably for at least 5 minutes, the external cigarette lighter cable can be unplugged.
4. What fuel should I use?
Use diesel fuel only. Do not use gasoline, alcohol, kerosene, mixed fuels, or unapproved flammable liquids.
5. Can I use it inside a tent, RV, or vehicle cabin?
Only if exhaust gas can be safely routed outdoors. Never allow exhaust gas to enter a tent, RV, vehicle cabin, boat cabin, shelter, or any occupied space.
6. Do I need an exhaust adapter?
If the heater is used with a sealed space or vehicle cabin, a compatible wall-through or tent exhaust adapter may be required to channel exhaust gases safely outdoors. Check the final kit configuration before use.
7. How hot is the heater during operation?
The heater and exhaust parts can become very hot during operation. Keep surrounding objects away from high-temperature areas and do not pack the unit until the fan stops and the screen turns off.
8. How long can it run on one tank?
Runtime depends on heat level, fuel level, outdoor temperature, insulation, ventilation, altitude, and the size of the space being heated. Fuel consumption is approximately 0.1L/h–0.48L/h.
9. What should I do before refueling?
Always shut down the heater before refueling. Stop operation immediately if any fuel leakage is detected.
