CONCENTRIC VENT TERMINAL INSTALLATION PROCEDURE
WARNING
Improper installation, adjustment, service, or maintenance can cause property damage, personal injury, or death.
Consult a qualified installer, service agency, or the gas supplier for information or assistance.
This kit must be used only for terminating this water heater. Do not use this termination kit for any other appliance.
Using this kit on other appliances and/or water heaters can result in property damage, personal injury, or death.
DO NOT operate this water heater until the installation and assembly of this kit is complete and the piping
completed. Failure to complete installation before operation can result in property damage, personal injury, or
death.
Before beginning any installation, be sure the main electrical disconnect switch is in the OFF position. Electrical
shock can cause personal injury or death.
DO NOT operate this water heater with the rain cap removed or recirculation of combustion products may occur.
Water may also collect inside larger combustion-air pipe and flow to the burner assembly. Failure to follow this
warning could result in product damage, or improper operation, personal injury or death.
CAUTION
DO NOT use field-supplied couplings to extend pipes. Airflow restriction will occur and the water heater pressure
switches may cause intermittent problems.
