- Connect Exhaust and Intake Pipes:
- Straighten the flexible exhaust pipe.
- Place a clamp on one end of the exhaust pipe and screw it into the bottom-left interface of the heater. Tighten the clamp securely.
- Take out the intake pipe, place a clamp on one end, and screw it into the bottom-right interface. Tighten the clamp.
- Insert both pipes through the drilled holes in your mounting surface.
- Secure Heater: Mark the positions for the bottom corner holes on the mounting surface. Drill pilot holes and secure the heater using the provided screws and nuts.
- Install Air Filter: Place a clamp on one end of the intake pipe. Screw the air filter onto the intake pipe and tighten the clamp. Use a fixing plate on the intake pipe sleeve and secure it with screws in the desired position.
- Install Silencer: Place a clamp on one end of the exhaust pipe. Screw the silencer onto the exhaust pipe and tighten the clamp. Attach the fixing screw and right-angle fixing plate to the silencer and secure it.
- Heating Duct Installation: Open the heating duct. Place a clamp at the duct interface and install it at the air outlet interface of the heater. Tighten the clamp to fix the heating duct.
- Power Connection:
- Remove the machine terminal position cover.
- For AC power: Connect the AC power adapter to the heater's power input and then to a 110-240V AC outlet.
- For DC power: Place the red (positive) and black (negative) copper rings of the battery power cord into the corresponding terminals on the heater and tighten them. Connect the other end to your 12V or 24V battery, ensuring correct polarity.
Video 1: Sunster Diesel Heater Installation Operation. This video demonstrates the step-by-step process of assembling and installing the diesel heater, including connecting pipes, mounting, and power connections.
Important: Flammable objects in contact with the exhaust pipe need to be filled with thermal insulation material. The exhaust pipe should be kept straight and not tilted upward to ensure smooth exhaust.
