WARNING
Use caution when washing the exterior of your vehicle. Water should not be sprayed directly into the furnace
vent. If water is forced beyond the rain baffles into the furnace vent, rusting of the furnace could occur. This
could also cause improper combustion.

system.
OASIS HYDRONIC HEATING
1
"For your comfort, your coach may be equipped with the Oasis heating system. This system uses a “boiler” and a pump
to heat and recirculate hot fluid through a series of convectors placed strategically throughout your unit. Fans located on
the convectors provide circulation of the warmed air for more even, efficient heating."
HOW HYDRONIC HEATING WORKS
"Hydronic central heating is the use of a heat generator commonly called a boiler (or furnace) to raise the temperature of
a heating medium, generally water or water and glycol mixture. The heated fluid is then circulated from the boiler
through pipes to heat emitters such as passive radiators, convectors and underfloor heating coils, through the interior of
the motorhome, and domestic hot water heat exchanger. The fluid loses its heat through this circulation and the cooler
fluid then returns to the boiler for reheating."
IMPORTANT
These brief operation instructions are for quick reference only. Any quick start instructions provided should
not take the place of the complete Operation Manual provided by this item's manufacturer.
WARNING
Never attempt to modify this furnace. Fire, explosion, asphyxiation, or carbon monoxide poisoning may occur.
If the furnace malfunctions, consult a trained service technician.
The Oasis system uses two different sources for heat. The primary heat source for the Oasis system, and most efficient,
is the diesel burner, which uses diesel fuel from the fuel tank to burn and create heat. The output of the diesel burner is
50,000 BTU’s.
The second heat source is an electric heating element. It is important to note the difference in the two systems. The
electric heating element has a 5000 BTU output and should be used only to help maintain the temperature once the
diesel burner has brought the system up to proper operating heat levels. From a cold start, the 5000 watt electrical
heating element will not operate the system alone.
OASIS ZONES
For heating, your unit is divided into three “zones” on your thermostat or your climate screen, if your coach is equipped
with the SilverLeaf system. The “Furnace” mode will appear in all four zones, but only three are active.
ZONE 1 - DASH, LIVING ROOM, AND KITCHEN CONVECTORS
These convectors are located under the dash and kitchen cabinets, and control heat in the cockpit, living room, and
kitchen areas. The dash mounted convector is the only one in your unit that has a two speed fan. The switch controlling
the fan speed is located in the front overhead cabinet adjacent to the diesel boiler switch.
ZONE 2 - MIDDLE AC AND HEAT PUMP
There are no Oasis furnace functions on this zone.
