75,000 BTU/h Forced-Air Heating Performance

The L.B. White Tradesman® K75 provides a rated heating capacity of 75,000 BTU/h for supplemental heating in suitable construction, industrial, and agricultural environments. Its forced-air system delivers a rated heated-air output of 265 cubic feet per minute (CFM), helping distribute warmth toward the intended work area. The direct-fired design transfers heat directly into the airstream, with manufacturer-stated fuel efficiency of 99.97%. Actual heating performance and coverage depend on ambient temperature, building construction, ventilation, air infiltration, and other site conditions.

Direct-Fired Kerosene Heating Technology

The L.B. White Tradesman® K75 uses direct-fired forced-air heating technology with an integrated fuel tank. The manufacturer specifies kerosene as the primary fuel and also identifies No. 1 and No. 2 diesel fuel and No. 1 fuel oil as approved fuel options. Combustion heats the air directly, delivering supplemental warmth without an indirect-fired heat exchanger. Because combustion byproducts enter the heated airstream, adequate ventilation and compliance with the manufacturer's operating restrictions are essential. Operate the heater only in applications permitted by the manufacturer and applicable safety requirements.

265 CFM Airflow & Heat Distribution

The L.B. White Tradesman® K75 provides a rated heated-air output of 265 CFM. Its integrated fan circulates heated air toward the intended work area, supporting directional supplemental heating in suitable industrial, construction, and agricultural environments. Keep the air inlet and outlet unobstructed during operation and maintain the clearances specified in the manufacturer's instructions. Do not attach ducting unless the manufacturer expressly approves the configuration for this model.

Portable Design & Flexible Installation

The L.B. White Tradesman® K75 features a compact, self-contained design with an integrated 5-gallon fuel tank. Manufacturer-published dimensions are approximately 32 inches long, 11.8 inches wide, and 16.8 inches high, with a shipping weight of approximately 30 lb. The onboard fuel supply supports deployment without a separate external tank. The manufacturer does not list wheels and handles as standard features for the K75. Position the heater on a stable, level surface and maintain all required clearances. Installation, fuel handling, and operation must follow the manufacturer's instructions and applicable local codes.

Fuel & Energy Management

The L.B. White Tradesman® K75 operates on kerosene and is also specified for No. 1 or No. 2 diesel fuel and No. 1 fuel oil. Its onboard fuel tank has a capacity of 5 gallons, with maximum fuel consumption of approximately 0.6 gallons per hour. The manufacturer lists a maximum operating time of approximately 8.3 hours per full tank under specified operating conditions. Actual runtime varies with operating conditions, fuel type, and fuel availability. The unit uses a fuel pump with a rated pump pressure of 3.8 PSI and requires a compatible electrical supply for the fan and ignition system. Confirm the electrical requirements against the current owner's manual and unit nameplate before operation.

Controls, Comfort & Electrical Connection

The L.B. White Tradesman® K75 includes a comfort-control thermostat, an on/off switch, dual-prong electronic spark ignition, and onboard fuel and pump-pressure gauges. The thermostat supports temperature management, while the gauges help monitor fuel availability and fuel-system operating pressure. The manufacturer's product specifications list a continuous operating current of 1.6 A and a motor rating of 1/8 horsepower. Voltage, frequency, plug type/NEMA configuration, and other electrical connection requirements should be verified against the current owner's manual and unit nameplate before publication and operation. Follow all manufacturer instructions for startup, shutdown, and safe operation.

Construction, Industrial & Agricultural Applications

The L.B. White Tradesman® K75 is designed for portable supplemental heating in suitable construction, industrial, and agricultural environments. Manufacturer product literature identifies the Tradesman K series for construction work sites and agricultural facilities, including swine buildings. Its 75,000 BTU/h heating capacity, 265 CFM heated-air output, and onboard fuel tank support temporary heating where directional warmth and portable deployment are required. Because the heater is direct-fired, applications must comply with the manufacturer's ventilation requirements, fuel-burning equipment regulations, and site safety procedures.

Mobility & Deployment

The L.B. White Tradesman® K75 features compact construction and an integrated fuel tank to support portable deployment. Its published dimensions of approximately 32 inches long, 11.8 inches wide, and 16.8 inches high allow placement in suitable work areas with adequate clearance. The manufacturer does not list wheels and handles as standard equipment on the K75, so transportation should be performed using safe handling procedures appropriate to the unit's weight and design. Position the heater securely and follow the manufacturer's instructions when moving, refueling, or preparing the unit for storage.

Safety, Service & Maintenance

The L.B. White Tradesman® K75 features dual-prong electronic spark ignition, an onboard air diagnostic system, fuel and pump-pressure gauges, a comfort-control thermostat, and a threaded drain plug. These features support startup, operating monitoring, troubleshooting, and maintenance. The manufacturer identifies CSA certification for the United States and Canada for the Tradesman K series. Inspect the heater, electrical cord, fuel tank, fittings, and fuel system before operation. Use only manufacturer-approved fuels, check fuel connections for leaks using an approved procedure, and maintain adequate ventilation. Keep combustible materials clear of the heater, do not operate damaged equipment, and follow the owner's manual for cleaning, servicing, draining, and storage. Never bypass safety devices or use the heater in applications prohibited by the manufacturer.
