approved side-wall horizontal vent system in the
Commonwealth of Massachusetts, be sure to
adhere to these additional requirements. These

A properly designed common venting system must
include vent temperature limit switches for each
appliance. All vent limit switches must be wired in
series so as to prevent any appliance from fi ring
in the event of a blocked vent. An outside draft
inducer must be installed to pull and create negative
pressure in the vent system. Refer to ANSI
®
Z223.1
or in Canada CAN/CSA B149.1 for more information
on common venting multiple appliances. Do not
connect vent systems of different categories to the
same venting system.

3.3.10 Inspection and Replacment of Existing
Vent System with New Components
When replacing an existing pool heater with the JXi,
it is recommended that a new appropriate venting
system is installed with the new heater.
However, if the existing venting system must be
used, be sure to carefully inspect the existing
system to ensure that it is in good condition
and appropriate for the JXi heater. Replace any
parts that are not in serviceable condition before
completing the installation.
3.3.9 Precautions Against Common Venting
Zodiac Pool Systems LLC does not recommend
using a common vent to vent multiple appliances
through a common duct. If no other option
is deemed available by the installer, seek the
assistance of a Registered Professional Engineer for
proper design of a common venting system.
