Exhaust & Combustion Air Intake Connections
The combustion air intake channels clean air into the heater. It can be eliminated if not required to ensure
clean air intake.
The exhaust tube channels exhaust safely away from the heater and vehicle. It also assists in providing a
required amount of back pressure required to balance the combustion process.
Exhaust Considerations:
• The exhaust is made using a heat resistant, 22mm flexible, stainless steel tube.
• Secure the exhaust tube to the heater using the exhaust clamp provided.
• Discharge exhaust away from passenger compartment.
• Ensure exhaust fumes cannot be sucked into combustion air intake.
• Install exhaust pipe with incline for moisture run off.
• Drill a small drain hole at low point if proper incline cannot be maintained.
• Route the exhaust pipe from the heater using “p” clamps provided.
• Route away from the vehicle slip stream.
Combustion Air Intake Considerations:
• The combustion air intake is made from a flexible, water resistant, paper / aluminum compound.
• Secure the combustion air intake tube to the heater using the clamp provided.
• Draw air from a clean air source away from water, dust and exhaust.
• The combustion air opening must be kept free at all times.
• Install combustion air intake tube with an incline for moisture run off.
• Route the combustion air intake using “p” clamps provided.
• Route away from the vehicle slip stream.
