The heating module uses a diesel burner (12 VDC)
controlled by a multi-functional electronic controller as
the primary source of heating coolant fluid (anti-freeze
and water). Two 1500 Watt, 120 Volt AC immersion
elements are used as secondary heat sources.
The heating module heats the coolant fluid to provide a
source of heat for all hydronic space heating needs.
When used with the distribution module and its integral
distribution pumps, the heating module has the ability to
circulate the coolant fluid to all space heating areas.
It can also provide a supply of domestic hot water using
the integral heat exchanger in the distribution module.
The 120 Volt power required to operate the Hydronic
Water Heating System may be provided by either
connecting the motorhome to an outside power source
when parked or by use of the motorhome generator.
NOTE:
For detailed information regarding the operation and maintenance of the Hydronic
Water Heating System refer to the manufacturer’s owner’s and operations manual.
1. Turn the water pump OFF.
2. The fresh water tank low point drain valve is located in the systems compartment. Drain
the tank by turning the drain cock to the open position.
NOTE:
When draining the entire on-board fresh water system, make sure to open all faucets,
the water heater drain, and the system low point drains to remove all fresh water from the
system.
3. When the system is finished draining, close all drains before filling again.
NOTE:
When traveling, you may want to drain the tank or keep the quantity of water to a
minimum. This reduces the total weight of the motorhome for travel.
