Plumbing the System
7.1 Before You Begin
For efficient and safe operation of The WaterHeater™ by ITR, follow
all recommendations for properly installing the plumbing system.
Any deviations from these must be approved in advance by ITR.
The WaterHeater™ by ITR if attached to the Space Heating Module
(optional) must use the following:

! DANGER
Use only a non-toxic propylene glycol based coolant with additives
generally recognized as safe ”GRAS” by the FDA in the coolant side
of the Space Heating Module.
For an efficient WaterHeater™ by ITR operation, you must:
•
Minimize the heat loss from the hoses and eliminate air from
the system.
•
Follow the flow directions for the fluids in The WaterHeater™
by ITR. Section 1 – Overview, Figure 1-1: Hot Water Heater
and Space Heating Module, if installed, shows how the water
flows through The WaterHeater™ by ITR and how the
circulation fluid (propylene glycol antifreeze and water is
recommended) flows in and out of the Space Heater Module .
Section 9 – Installing the Space Heating Module , Figure 9-1:
Space Heating Module Plumbing Fittings, shows a typical
plumbing layout for circulating to the cabin fans.
When heat is called
for, the heating
water pump in the
Space Heating
Module (optional)
sends heated fluid
out to the cabin
fans.
