However, if no other option is deemedavailable by the installer, each appliance must haveits own vent temperature limit switch. All vent limitswitches must be wired in series so as to prevent anyappliance from firing in the event of a blocked vent.An outside draft inducer must be installed to pull andcreate negative pressure in the vent system. Refer toANSI® Z223.1 or in Canada CAN/CSA B149.1 for moreinformation on common venting multiple appliances. Donot connect vent systems of different categories to thesame venting system.3.3.6 Inspection and Replacement of Existing Vent System with New ComponentsWhen replacing an existing pool heater with the JXi, itis recommended that a new appropriate venting systemis installed with the new heater.
