Flue gases can be very hot and can contain carbon
monoxide which can cause property damage, severe
injury or death. Make sure the unit is off and cool to
the touch before attempting these instructions.

the main gas supply to the heater at the meter or
the manual gas cock outside the heater.

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-prole 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).
