B. The burner shall be a stainless-steel pipe configuration with flame holes down the length of both sides of the burner as well as flame holes at the end of the pipe cap to heat the material discharge chute area.

C. The burner flame shall contact the stainless-steel flame spreader instead of the material tank directly.

D. The burner exhaust gas shall be vented through the side air baffles and end caps through openings along the top edges of these panels

IGNITION OF BURNER

A. The burner shall be lit by a constant duty high voltage transformer powering an electric spark igniter.

B. This igniter shall work with a sensor that detects a lack of burn or ignition and shuts down the fuel supply.

C. The thermostat control is located in the control box.

TEMPERATURE CONTROL

A. The mixer shall have a thermostatic control device that will automatically regulate tank and material temperature.

B. The control shall have a digital readout for temperatures of tank and material.

ACCESSORIES to be included

A. Window Mount Assembly The in-cab control system is meant to be hung on the “ROPS” (roll over protection system) cage of the skid steer loader’s cab. Most brands of loaders have optional comfort system (heat and AC) that include window panels. Some brands place these window panels INSIDE the ROPS cage eliminating the ability to hang the in-cab control system.

This Window Mount Assembly includes 4 large suction cups and provides a steel frame to hang the in-cab control system.

B. 12V Plug Adapter This machine requires 12VDC from the skid steer loader via a 12V power socket (aka “cigarette lighter plug”)… Some older loaders may not have this feature, so this adapter is a 2meter cable with the 12V power socket on one end and large battery clamps on the other.
