These items will replace the existing parts that are cur-
rently installed in the unit. Make sure that all parts are
replaced and properly installed by a qualified service
agency.

tings on the water heater for use with the proper gas
type. The gas pressure values at both the gas supply
inlet fitting and at the manifold inlet on the unit are veri-
fied by the installer. Proper adjustments will be made to

in ac-
pleted, a final gas leak check will be performed to con-
firm that all parts have been securely installed.

verify the proper gas conversion kit with
your water heater model on the table
