Installation Instructions
Legacy
FOR YOUR SAFETY - This product must be installed and serviced by personnel qualified in pool/spa
heater installation. Improper installation and/or operation can create carbon monoxide gas and flue gases
which can cause serious injury, property damage, or death. For indoor installations, as an additional
measure of safety, Zodiac Pool Systems, Inc. strongly recommends installation of suitable Carbon
Monoxide detectors in the vicinity of this appliance and in any adjacent occupied spaces. Improper
installation and/or operation will void the warranty.
These instructions are to be used with the following Jandy
R0491601-05 -- Vent Cap Assembly, Legacy, Replacement Kit
R0499601-05 -- Draft Hood, Indoor, Legacy, Replacement Kit
If the information in these instructions is not followed exactly, a fire or explosion may result causing
property damage, personal injury or death.
NOTE When installing a new pool heater that will connect to existing venting, some adaptation of the vent system will
be required. This is due to variations in venting centerlines with the replacement heaters. In the USA, refer to
the National Fuel Gas Code (ANSI Z223.1/NFPA 54) and all local codes. In Canada, refer to the Natural Gas
and Propane Installation Code (CSA B149.1) and all local codes.
NOTE Jandy ships the heater with the low-profile top for an outdoor installation. Follow these procedures to install
either the Jandy draft hood (a draft hood is required on all indoor installations) or the vent cap (outdoor
installations).
This document gives instructions for installing/
replacing the Vent Cap and Draft Hood in all Jandy
Legacy model pool/spa heaters. The instructions must
be followed exactly.
These instructions were written with safety as the
priority. Not following the written procedure or taking
short cuts may increase the risk of personal injury. Read
through the instructions completely before starting the
procedure.
Before starting the procedure, use the parts list at
the back of these instructions to identify the parts that
