NOTE
For approved side wall vent kits and specific
installation instructions, see
Section 11,
Replacement Parts
.
Zodiac Pool Systems, Inc. does not recommend
using a "Common Vent" to vent multiple appliances
through a common duct. However, if no other option is
deemed available by the installer, each appliance must
have its own vent temperature limit switch. All vent
limit switches must be wired in series so as to prevent
any appliance from firing in the event of a blocked
vent. Refer to ANSI Z223.1 or, in Canada, to CAN/
CSA B149.1 for more information on multiple venting.
Do not connect vent systems of different categories
to the same venting system. Seek the assistance of a
Registered Professional Engineer for proper design of
a common venting system.
3.3.3 Inspection and Replacement of
Existing Vent System with New
Components
If the LXi is being installed to replace an existing
pool heater, it is recommended that a new appropriate
venting system be installed with the new heater. How-
ever, if an existing venting system must be used, be
sure to carefully inspect the venting system to ensure
that it is in good condition and continues to be appro-
priate for the LXi heater. Replace any parts that are
not in good and serviceable condition with new parts
before completing the pool heater installation.
foot (2 cm/m). The LXi is designed for Category III
venting with a maximum of 25 ft (7.6 m) of vent pipe
and up to three (3) elbows. For each additional elbow,
reduce the maximum vent pipe length by 10 ft (3 m).
See Table 4 for the minimum vent diameter for the
model size to be installed.
Side wall vents must be installed and located in
accordance with the National Fuel Gas Code
®
NFPA
54 / ANSI Z223.1 or the Canadian Natural Gas and
Propane Installation Code CAN/CSA-B149.1. See
Figure 8 Side Wall Vent Terminations.
