YATO YT-99738 Diesel Space Heater, 20 kW, 230 V, with Flue Outlet

The YATO YT-99738 is a portable 20 kW liquid fuel forced-air heater designed for heating workshops, warehouses, production facilities, utility rooms, and other working environments. A key feature of this model is its ability to connect to a suitable flue system, allowing combustion gases to be directed outdoors when installed according to the manufacturer's instructions.

The heater operates on diesel or kerosene, delivers an airflow of 600 m³/h, and features a 38-litre fuel tank. The manufacturer indicates an approximate heating area of up to 200 m². An adjustable thermostat, LED display, and flame failure sensor provide additional functionality, while the transport wheels and handle make the 21.3 kg heater easier to move.

Advantages & Additional Information

• 20 kW heating capacity – designed for heating workshops, warehouses, utility rooms, and working areas.

• Flue connection capability – allows connection to a combustion exhaust system that meets the manufacturer's requirements.

• 600 m³/h airflow capacity – the integrated fan helps distribute warm air throughout the heated space.

• 38-litre fuel tank – allows longer operating periods between refills.

• Adjustable thermostat and LED display – provide convenient temperature adjustment and monitoring.

• Flame failure sensor – designed to monitor the combustion process.

• Portable construction – metal housing, transport wheels, and handle make the unit easier to move.

Flue Connection Capability

One of the main differences between the YATO YT-99738 and conventional direct-fired diesel heaters is the option to connect a combustion exhaust system.

When correctly installed, the system allows combustion gases to be directed outdoors, reducing their release into the heated environment. This is particularly relevant for workshops, warehouses, and other workspaces where indoor air quality must be considered.

The flue pipe is not included in the standard package and must be purchased separately.

The exhaust system must comply with the manufacturer's requirements, including pipe diameter, length, permitted bends, and safe outdoor discharge. The hot air outlet diameter (235 mm) is not the flue connection diameter.

Applications & Usage

The YATO YT-99738 can be used in workshops, automotive service centres, warehouses, production facilities, utility rooms, and construction or renovation sites.

The heater is suitable for supplementary heating and for increasing ambient temperature during repair and drying work. A correctly installed flue system can be beneficial in applications where reducing the release of combustion products into the workspace is important.

When using the heater for drying applications, follow the building material manufacturers' requirements regarding temperature, humidity, and ventilation.

Temperature Control and Operation

The heater features a manually adjustable thermostat that allows the desired temperature to be selected. The LED display shows ambient temperature, making it easier to monitor heating conditions.

A flame failure sensor is included to monitor the combustion process and adds to the unit's protective functionality.

38-Litre Fuel Tank and Mobility

The heater features an integrated 38-litre fuel tank. The manufacturer's specified fuel consumption is 1.65 kg/h.

Actual operating time depends on fuel density, the selected temperature setting, and operating cycles.

Transport wheels and a handle make it easier to move the 21.3 kg heater between work locations. Before transportation, switch off the unit and allow it to cool according to the manufacturer's instructions.

Important Safety Information

The YATO YT-99738 has flue connection capability, but safe operation depends on correct system installation.

Before use, ensure that the flue system is properly installed, sufficient combustion air is supplied, adequate ventilation is maintained, and the manufacturer's specified safety clearances from combustible materials are observed.

The ability to connect a flue does not automatically make the heater suitable for residential living spaces, sleeping areas, or unventilated rooms.

Its IPX4 protection rating provides protection against water splashes under the applicable test conditions but does not permit immersion in water or unrestricted operation in wet environments.
