Measure out the mounting location along an interior wall of the cargo space. Keep the heater mounted toward the bottom third of the cargo wall, as hot air rises. Mark the mounting bracket screw holes and drill them out.
Mount the heater bracket to the wall via the power screwdriver. Use bolts to secure it to the cargo trailer wall, and take care not to go all the way through the wall, damaging the exterior of the cargo trailer.
Secure the heater to the wall-mounting bracket. Most heaters use screws to secure the heater to the bracket. Tighten the screws to ensure the heater is tight and secured against the wall.
Attach the two LP tank circular brackets within two feet of the heater but close to the ground. The brackets are similar to barrel loops but have a tightening slide in the center. Mount them to the wall with bolts and the power screwdriver. Slide the tank into the brackets and tighten. Run the LP tank hose to the heater.
Open the back of the cargo trailer and slide the loading dock down. Pull the roll on heater to the cargo trailer.
Push the heater to a corner or out of the way location. Be sure no cargo will touch the heater to prevent fire hazards.
Secure the heater to any cargo loops along the side of the trailer. Use chains or bungee cords to keep the heater in position and set the foot brake on the heater dolly.
