YATO YT-99739 Diesel Space Heater, 30 kW, 50 L, with Flue Exhaust Connection Option

YATO YT-99739 – 30 kW Diesel Heater with Flue Exhaust Connection Option

The YATO YT-99739 is a 30 kW liquid fuel forced-air heater designed for heating larger working spaces and maintaining temperatures at construction sites. The unit delivers 795 m³/h airflow, helping distribute heat throughout workshops, warehouses, production facilities, and construction environments. The manufacturer specifies an indicative maximum heating area of up to 300 m².

A key feature of this model is its flue exhaust connection option. When an appropriate exhaust system is installed according to the manufacturer's requirements, combustion products can be directed outside the heated area. The heater also features a 50-litre fuel tank, adjustable thermostat, LED display, and flame failure sensor.

Advantages & Additional Information

• 30 kW heating capacity – for intensive heating of larger working environments.

• 795 m³/h airflow – the fan helps distribute warm air throughout the space.

• 50-litre fuel tank – reduces the need for frequent refuelling.

• Up to 300 m² declared heating area – indicative manufacturer specification.

• Flue exhaust connection option – allows an appropriate combustion exhaust system to be connected.

• Adjustable thermostat and LED display – for temperature settings and ambient temperature monitoring.

• Flame failure sensor – monitors the combustion process.

• IPX4 protection rating – protection against water splashes according to the applicable rating definition.

• Transport wheels and carrying handle – make the 26.5 kg heater easier to move.

Flue Exhaust Connection Option

The YATO YT-99739 is designed with an option to connect a combustion exhaust system.

This is particularly relevant for workshops, warehouses, technical facilities, and construction sites where proper removal of combustion products is important.

The exhaust system must be selected according to the manufacturer's instructions, including the required connection diameter, pipe construction, discharge location, and other installation requirements.

The flue exhaust pipe is not included in the standard package.

It is important to distinguish between two different connections: the 230 mm diameter specified in the technical data refers to the hot air outlet, not the flue exhaust connector.

30 kW Heating Capacity and 795 m³/h Airflow

The 30 kW heating capacity allows the unit to generate substantial amounts of heat, while the integrated fan delivers 795 m³/h airflow to help distribute heat throughout the working environment.

The manufacturer specifies a maximum heating area of up to 300 m², but this is not a guaranteed result under all conditions.

Heating performance depends on room volume, ceiling height, insulation, initial temperature, outdoor conditions, and ventilation requirements.

Adjustable Thermostat and LED Display

The heater features a manually adjustable thermostat that allows users to select the desired temperature.

The LED display is used to monitor ambient temperature, making it easier to control heating conditions.

A flame failure sensor is also included to monitor the combustion process.

50-Litre Fuel Tank

The YATO YT-99739 features a 50-litre fuel tank, suitable for longer operating periods.

The manufacturer specifies 2.4 kg/h fuel consumption. Actual operating time depends on fuel use, heating cycles, and environmental conditions.

Since tank capacity is specified in litres and fuel consumption in kilograms per hour, exact runtime cannot be calculated directly without considering fuel density and operating conditions.

Applications & Usage

The YATO YT-99739 can be used in workshops, automotive service centres, warehouses, manufacturing facilities, agricultural buildings, construction sites, and other working environments where appropriate combustion exhaust routing and ventilation can be provided.

The heater may also be used to maintain suitable temperatures during construction and renovation work. Effective drying depends not only on heating but also on sufficient moisture removal from the space.

Electrical Supply and IPX4 Protection

The heater operates on a 220–240 V, 50 Hz electrical supply. Electricity is required for the fan, control system, and other electrical components.

The fan motor power is 340 W.

The heater has an IPX4 protection rating, indicating protection against water splashes. This does not mean that the heater is fully waterproof or suitable for unrestricted outdoor use.

Important Safety Information

The YATO YT-99739 should not automatically be classified as an indirect-fired heater solely because it offers a flue exhaust connection option. The manufacturer uses the term “Oil Fired Direct Heater” in its product naming, so the operating manual for this specific model must be followed.

The combustion exhaust system must be properly installed and routed to a safe discharge location. Even with an exhaust connection, the manufacturer's fresh air supply and ventilation requirements must be met.

Do not use the heater in residential living spaces, sleeping areas, or other environments for which the manufacturer has not approved it. Maintain appropriate clearances from combustible materials and follow all fuel system and electrical safety requirements.
