APPLIANCES AND SYSTEMS

Hot Water
The Hydronic Heating System allows water to
be heated as it is being used. A continuous supply
of hot water is obtained through a tankless, on-
demand hot water system.
Interior Heat
This system is also equipped with circulation
pumps, which allow individual interior heating
zones. Whenever the room thermostat calls for
heat, the water heating solution is circulated
through interior heat exchangers (similar to
radiators) located throughout your RV that
distributes heat quietly and evenly.

Engine Preheating/Motoraid
Also included in this system is a motoraid
feature, which uses heat generated by the RV
engine during travel to transfer heat to the water
heating solution in the boiler tank. This process
allows the boiler tank to remain heated, which
reduces the time required to bring the tank to
operating temperature for continuous hot water
and interior heat.
The Hydronic Heating System also includes
an engine preheat feature. This allows for easy
engine start-up whenever cold weather
conditions exist.
The Hydronic Heating System can be
operated off of the 120-volt AC electric heating
element or the 12-volt DC diesel burner.
NOTE: Please note that the diesel burner is the
primary heat source for heating both the
interior and the domestic hot water (such
as when cool ambient temperatures exist
and/or when there is a high demand for
domestic hot water).
Expansion Fill Tank
• Check antifreeze/water heating solution
level monthly. When the system is at
maximum operating temperature (i.e.
immediately after the diesel burner cycles
OFF), the fluid level should be at the level
marked HOT.
• If fluid level is low, see the Maintenance
Section in the manufacturer’s operating
manual for replenishing the antifreeze/
water heating solution.
NOTE: Use only Aqua-Hot
®
approved
propylene glycol-based
antifreeze.
