APPLIANCES
■ ROOF MOUNTED AIR CONDITIONERS
(12 VDC AND 115 VAC)
The American Coach Patriot is equipped with either the 13,500 BTU
Dometic 125 VAC roof mounted air conditioner, or the optional 20,000
BTU ProAir 12 VDC roof (if your coach is equipped with Lithium
Package). Both units are highly efficient at maintaining a quality
comfort level within the vehicle� With routine care and maintenance
they are trouble free�
■ CABIN HEATER
Your coach is equipped with either the ESPAR Airtronix D2 or the
ProAir D3 forced air furnace and climate control system, depending on
the model and options installed� Both units operate on diesel fuel from
the Mercedes-Benz Sprinter’s onboard fuel tank� The unit is located
at the driver’s side rear of the coach beneath the power folding rear
bench seat� A small louvered vent cover is located adjacent to the
furnace, which should never be blocked or restricted�
The ESPAR and ProAir diesel furnaces operate similarly� Ambient air
enters the unit through the intake (F) and is passed through the
furnace by its internal blower where it is heated� Heated air exits from
the outlet (W) and ventilates into the coach through a vent located at
the bottom of the driver’s side rear ottoman seat�

Both units utilize the vehicle’s internal diesel fuel and electrical power
supply to produce heat without idling the vehicle� The advantage of
using a diesel heater over Liquid Propane Gas (LPG) is that diesel is a
“dry” fuel source, meaning it will not cause moisture to build up inside
the vehicle�
These heaters are quite efficient as they can run under average
conditions for approximately 24 hours on one (1) gallon of diesel
fuel� Actual fuel consumption will depend upon the size of the coach,
the interior thermostat temperature setting and the outside ambient
temperature� Be aware that your diesel furnace will slowly draw down
the coach’s fuel tank level over several days, so you may need to fill
up before overnighting for an extended period in a remote area�
Both the ESPAR and ProAir units are combustion heaters, so it is
important to inspect your Carbon Monoxide (CO) Detector prior to
every trip in accordance with SECTION 4 – SAFETY� When using the
diesel furnace for the first time, you may detect a slight burning odor
emanating from the unit inside the coach� This is normal during the
break in period, and the odor will disappear after the unit has operated
for a while� You may also notice some temporary white smoke coming
from the heater’s exhaust pipe at the driver’s side rear of the coach�
This is normal at startup and the smoke should rapidly clear once the
unit achieves full power� Persistent smoke is an indication that the
heater requires service�
