This document is an instruction manual for the Fanmaster HDR20 Industrial Diesel Radiant Heater.
Function Description
The Fanmaster HDR20 is an industrial diesel or kerosene portable radiant heater featuring an open combustion chamber. It is designed for industrial use, providing heating through radiant heat. The operating principle involves an internal burner fan supplying airflow for proper combustion. This air mixes with high-pressure fuel, which is drawn from the tank by an electrical pump and delivered to the nozzle under high pressure. Adequate ventilation is required for its operation, and it is not intended for domestic or recreational vehicle use.

Operating Instructions (Start-Up):
- Position the heater on a flat, level, non-flammable, and solid surface in an upright position.
- Ensure the heater is not near walls, corners, low ceilings, below a power socket outlet, or on moving vehicles.
- Keep the heater away from flammable, combustible, explosive, or corrosive materials, as well as curtains or similar materials that could block air inlet/outlet.
- Do not block or restrict the air inlet and outlet.
- Keep the power cable away from heat sources, sharp edges, cutting, and moving parts.
- Avoid exposing the heater directly to weather or excessive humidity, and do not place it near a bath, shower, or swimming pool.
- Maintain minimum safety clearances: Side: 0.6m, Air inlet side: 1m, Top: 1.5m, Hot air outlet side: 3m.
- Fill the tank with clean Diesel or Kerosene only.
- Connect the plug to a relevant power source. The electrical system must comply with local regulations and include a Residual-Current Device (RCD).
- Turn the "ON/OFF" switch to "ON" (I). The heater will turn on after a few seconds.
- Check the position of the thermostat.
Operating Instructions (Shutdown):
- Move the switch to the "OFF" (O) position.
- Never disconnect the heater from the mains to stop it during operation.
- Always allow the cooling sequence to complete to prevent damage to internal components from residual heat.
- Do not cover the heater or block the air inlet and outlet.
- The heater outlet is very hot during and after operation; use personal protective equipment if needed.
- Unplug the heater before moving it. Never pull the cable to unplug or move the unit.
Safety Warnings:
- Read instructions carefully and keep the manual for future reference.
- Only persons who have read and understood the instructions should assemble, adjust, or operate the heater.
- Failure to follow instructions can result in property damage, serious injury, or loss of life due to fire, explosion, burns, asphyxiation, carbon monoxide poisoning, and/or electrical shock.
- Adequate ventilation is required; do not use in enclosed environments. Unvented portable heaters consume oxygen from the existing area.
- Do not store or use gasoline, petrol, or other flammable/combustible vapors/liquids near the heater.
- Keep solid combustibles (building materials, paper, cardboard) a safe distance from the heater.
- Never use the heater in spaces containing volatile or airborne combustibles, or products like gasoline, solvents, paint thinner, dust particles, or unknown chemicals.
- Direct-fired heaters can cause carbon monoxide (CO) poisoning if used incorrectly (e.g., indoors without adequate air circulation) or if not properly working. CO poisoning can be fatal.
- Unplug the appliance before maintenance.
- Always check the power cable for damage. If damaged, it must be replaced by Fanmaster, a service agent, or qualified personnel.
- The front outlet is very hot; do not touch.
- Do not leave the heater unattended when in use.
- Never use the heater with wet hands or when the heater or power cable is wet.
- Children must be supervised and should not play with the heater.
- The heater is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge.
