Location and Clearances:
• Place the heat exchangers so that even heat distribution
will be felt throughout the interior of the motorhome.
Reference Figures 14 and 17.
NOTE:
For single slide-out configurations, it is usually simplest
to place a heat exchanger on the opposite side of the
motorhome pointing towards the slide-out.
•
Place the heat exchangers where they will be accessible
for potential servicing and cleaning.
•
Centralize and position a heat exchanger in the fresh
water storage tank plumbing bay. Reference Figure 12.
NOTE:
In order to achieve the best heating results, place the
heat exchanger as close to the floor of the plumbing
bay as possible (heat will naturally rise).
•
Reference Figures 12, 13, and 14 for mounting location
information.
•
Reference Figure 13 for clearance information.
NOTE: An accessory device is available for the Cozy Heat Ex-
changer for the purpose of redirecting the airflow from
the heat exchanger. Reference Figure 16.
Mounting Requirements:
•
Sufficient ventilation (return-air) must be supplied to
each interior heat exchanger. Reference Figures 14 and
15.
NOTE:
Mounting the heat exchangers without sufficient venti -
lation will severely reduce their overall heating perfor-
mance (heat output).
In order to provide sufficient ventilation, the return-
air registers must be the same size, or larger, than the
outlet-air registers.
Return-air must be supplied from the corresponding
interior heating zones.
