Field Wiring ConnectionVentingGeneralAppliance CategoriesHeaters are divided into four categories based on thepressure produced in the exhaust and the likelihood ofcondensate production in the vent.Category I – A heater which operates with a non-pos-itive vent static pressure and with a vent gastemperature that avoids excessive condensate pro-duction in the vent.Category II – A heater which operates with a non-pos-itive vent static pressure and with a vent gastemperature that may cause excessive condensateproduction in the vent.Category III – A heater which operates with a positivevent pressure and with a vent gas temperature thatavoids excessive condensate production in the vent.Category IV – A heater which operates with a positivevent pressure and with a vent gas temperature thatmay cause excessive condensate production in thevent.See Table J for appliance category requirements.Use only the special gas vent pipes listed for use withCategory IV gas burning heaters, such as the AL29-4Cstainless steel vents offered by Heat Fab Inc. (800-772-0739), Protech System, Inc. (800-766-3473),Z-Flex (800-654-5600) or American Metal Products(800-423-4270). Pipe joints must be positively sealed.Follow the vent manufacturer’s installation instructionscarefully.Support of Vent StackThe weight of the vent stack or chimney must not reston the heater vent connection. Support must be pro-vided in compliance with applicable codes. The ventshould also be installed to maintain proper clearancesCAUTION: Label all wires prior to disconnectionwhen servicing controls. Wiring errors can cause im-proper and dangerous operation. Verify properoperation after servicing.Fig. 22: Rear Wiring LocationDANGER: SHOCK HAZARDCAUTION: Proper installation of flue venting iscritical for the safe and efficient operation of theheater.NOTE: For additional information on appliancecategorization, see appropriate ANSI Z21 Standardand the NFGC (U.S.), or B149 (Canada), orapplicable provisions of local building codes.WARNING: Contact the manufacturer of the ventmaterial if there is any question about the appliancecategorization and suitability of a vent material forapplication on a Category III or IV vent system.Using improper venting materials can result inpersonal injury, death or property damage.NOTE: A grounding electrode conductor shall beused to connect the equipment groundingconductors, the equipment enclosures, and thegrounded service conductor to the groundingelectrode.CAUTION: Condensate drains for the vent pipingare required for installations of the XTherm. Followvent manufacturer instructions for installation andlocation of condensate drains in the vent.Condensate drain trap must be primed with water toprevent gas flue leak and must be routed to anappropriate container for neutralization before dis-posal, as required by local codes.Make sure electrical power to the heater is discon-nected to avoid potential serious injury or damage tocomponents.California Hot Water Supply, Inc.(800) 249-724422
