D2/D4 Heater Installation (continued)
Exhaust and Combustion Air Intake Routing
IMPORTANT: Correct installation of this heater is necessary to ensure safe and proper operation.
BEFORE installing the heater, thoroughly read and understand the heater manufacturer’s manual included with
the heater.
DANGER: The correct installation of the exhaust and combustion air intake hoses is extremely important to prevent
carbon monoxide poisoning or asphyxiation.
EXTREME CARE MUST BE TAKEN TO
:
•
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.
•
DO NOT mount the exhaust hose to the tractor’s frame. It must be installed to the cab to allow for movement.
Installation
DANGER: The exhaust hose outlet must exit at least 3 feet from the A/C evaporator drains located under the tractor
to prevent carbon monoxide poisoning or asphyxiation.
ALWAYS VERIFY the two water valves (kazoos) are installed onto the evaporator drain tubes and are secured with
hose.
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.
b. 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!
