Portable Propane Torpedo Heater

The Dayton 3VE57 is a liquid-propane torpedo heater built for outdoor and well-ventilated workspaces. It delivers 125000 BtuH of heating output and covers up to 3100 sq ft. Continuous spark ignition fires the burner from an electric source. An automatic safety shut-off and flame-out sensor cut fuel flow if the flame is lost.

Job-Site Crews and Outdoor Events

This heater suits teams needing high-output spot heat on construction sites, loading docks or open-air gatherings where a 40 lb propane cylinder is practical. It is not for indoor residential rooms, enclosed garages without fresh-air exchange, or anyone who needs a built-in thermostat or digital temperature readout.

125000 BtuH Heating Capacity

The single figure that decides fit is the 125000 BtuH rating. Match that number to the cubic volume and heat-loss calculation for your space; if the load is lower, a smaller heater will do the job with less fuel.

Questions about this item

How do I connect the 40 lb propane cylinder and what step is most often missed?

Attach the regulator hose to the cylinder valve, open the valve slowly, then press the continuous spark igniter; the step most often missed is waiting a few seconds after opening the valve before igniting to let gas reach the burner.

What part will need replacement after extended use on this 125000 BtuH heater?

The flame-out sensor and continuous spark electrode are the wear items that typically require replacement after long heating seasons.

At what point does the automatic safety shut-off activate during continuous operation?

The shut-off triggers if the flame-out sensor detects loss of flame or if the unit overheats, cutting fuel flow to prevent unsafe conditions.
