Plumbing the System
7.1 Before You Begin
For efficient and safe operation of the Hurricane
®
Chinook Heating
System, follow all of the recommendations in this section for
properly installing the plumbing system. Any deviations from these
must be approved in advance by ITR.
The Hurricane
®
Chinook Heating System must use a non-toxic,
propylene glycol based coolant with additives generally recognized
as safe ”GRAS” by the FDA. Use of non-propylene glycol based
coolant can be harmful if contamination of potable water occurs due
to a leak in the heat exchanger, which could be caused if the fresh
water in the system is allowed to freeze.
For an efficient Hurricane
®
Chinook Heating System operation, you
must:
•
Minimize heat loss from the Hurricane
®
Chinook and hoses.
•
Balance the heat output for each of the zones. Balancing can be
done by adjusting the number and size of the cabin fans installed
in each space heating zone. Figure 7-2:
Plumbing Hurricane
®
Chinook Heating System for Five Zones,
shows a typical
plumbing layout for circulating coolant from the Hurricane
®
Chinook to the cabin fans, in a single loop, and back to the
Hurricane
®
Chinook.

DANGER
When heat is called
for, the distribution
pumps in the Chinook
send heated fluid out
to the cabin fans and
potable
water
