L.B. WHITE

L.B. WHITE portable gas torpedo heaters, such as the CP400DF and CP170ESPN21163T6, are designed for use with either natural gas or propane. Specific models may be configured for one fuel type or convertible via a field-installed conversion kit. Always verify the fuel designation on the nameplate before operation. Propane models typically require a vapor-withdrawal regulator and hose assembly. Natural gas models connect to a fixed gas supply line. The heater’s BtuH output rating is based on the fuel’s heating value; propane and natural gas will yield slightly different outputs due to their energy content per cubic foot.

L.B. WHITE torpedo heaters (e.g., CP170ESPN21163T6) are direct-fired units that discharge heated air directly into the space. They are compact and portable, suitable for open areas like construction sites. Ducted tent heaters (e.g., CS350ESDN22168T) are also direct-fired but include a duct flange or collar that allows connection to flexible ducting. This enables directing heat into enclosed structures such as tents, remediation enclosures, or drying rooms. Ducted models often include a built-in air pressure gauge to monitor duct static pressure. Both types are direct-fired; combustion gases enter the heated space, so ventilation must be maintained.

L.B. WHITE portable heaters include standard safety features such as a flame-sensing thermocouple or electronic flame detection that shuts off gas supply if the flame is extinguished. Many models, like the CP400DF, include LED diagnostics for troubleshooting. Units with thermostats (e.g., CP170ESNN21163T) provide automatic on/off cycling based on set temperature. All models are designed to meet ANSI Z83.7 / CSA 2.14 standards for construction and performance. The heaters are equipped with a tip-over switch that interrupts gas flow if the unit is tilted beyond a safe angle. Electrical components are enclosed to protect against moisture and debris.

L.B. WHITE direct-fired heaters are intended for use in well-ventilated areas. They are not recommended for occupied indoor spaces without adequate ventilation because combustion byproducts (carbon monoxide, carbon dioxide, nitrogen oxides) are released into the heated air. For occupied spaces, indirect-fired heaters that vent combustion gases outdoors are required. L.B. WHITE does not manufacture indirect-fired models. Always follow local codes and the manufacturer’s instructions regarding ventilation. In construction or industrial settings, these heaters are typically used in areas with natural air exchange or mechanical ventilation.

3G Electric supplies L.B. WHITE accessories including end diffusers for ducting (e.g., SKU 16W313, a steel end diffuser compatible with ducting for portable gas heaters). Other accessories may include hose and regulator assemblies for propane operation, duct clamps, and replacement thermostats. The diffusers are designed to reduce air velocity and distribute heat more evenly at the end of a duct run. For specific model compatibility, refer to the manufacturer’s parts list. 3G Electric can provide replacement parts for L.B. WHITE heaters, including ignition components, fan motors, and gas valves.
