Hydronic Heating and Hot Water System

Your Touring Coach has a gas/electric hydronic heating
and on-demand hot water system that runs on gasoline
and an electric element, eliminating the need for LP
gas� The system gets its fuel from the vehicle's gas
tank�
NOTE
The system will automatically shut OFF if the
Coach's fuel tank reaches the one-quarter level,
leaving enough fuel to travel to a refilling station.
The heater portion of the system operates by
circulating a heat transfer fluid (RV boiler antifreeze)
through quiet air handlers that provide soft, radiant
heat to warm the Coach's interior� When the Coach is
cold, the fans run on high until the interior temperature
reaches its target� The fans then automatically slow
down to maintain comfort levels�
The water heater portion of the system circulates
the same fluid through an instantaneous water heat
exchanger, which produces hot water for showers and
faucet use�
The Timberline touchscreen display (shown above)
controls the system� When making selections, the
display's various touch controls change from blue OFF
to orange ON�
The controls allow you to adjust the heat and whether
you want to utilize gasoline and/or electric:
• The HEATER icon controls the gasoline burner
• The ELEMENT icon controls the 1500W electric
element that only functions when connected to
shoreline power
See your Owner's Packet for a copy of the Timberline
User Manual, where you will find detailed operation,
maintenance, and troubleshooting instructions� Or, visit
