EEXXTTRREEMMEE CCAARREE MMUUSSTT BBEE TTAAKKEENN TTOO::
• Route the exhaust outlet hose and combustion air intake tube so they cannot be plugged by dirt, water or snow.
• Ensure the exhaust outlet and air inlet do not face into the tractor’s slip stream to prevent “ram air” effect.
• Keep exhaust outlet and air intake hoses a minimum of 12” apart.
• Install exhaust hose so it will maintain a minimum distance of 2.00 inches (50.8 mm) from any heat sensitive or
flammable material.
• The exhaust hose should be mounted slightly downwards to help drain off condensation.
• Install the protective cap onto the end of the exhaust hose.
• Route the exhaust hose to an open area to the rear or side of the tractor so fumes cannot build up and enter the cab
or the combustion air inlet tube to the heater.
• DDOO NNOOTT mount the exhaust hose to the tractor’s frame. It must be installed to the cab to allow for movement.
Exhaust and Combustion Air Intake Installation
1. Route the exhaust hose to an open area to the rear or side of the tractor positioned slightly downwards to help drain
off condensation and secure with clamps.
a. Drill a 1/8” hole in exhaust hose if necessary to allow for water drainage.
NNoottee:: Exhaust hose can be shortened to a minimum of 8” if required.
2. Attach metal end cap to exhaust hose.
3. Position air intake tube facing towards the rear of the tractor where it can pick up clean, fresh, moisture free air.
4. From underneath the sleeper:
a. Apply silicone sealant around ONLY the four heater mounting screws.
b. DO NOT apply any sealant around the access hole!
IImmppoorrttaanntt:: AALLWWAAYYSS VVEERRIIFFYY the two water valves (kazoos) are installed onto the evaporator drain tubes and are
