CONCENTRIC VENT TERMINAL INSTALLATION:
PROCEDURE
Improper installation, adjustment, service, or mainte-
nance can cause property damage, personal injury, or
death. Consult a qualified installer, service agency, or
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.
NOTICE: Concentric vent kit requires that the joints be
cemented.
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, improper operation, personal injury or death.
DO NOT use field-supplied couplings to extend pipes.
Airflow restriction will occur and the water heater
pressure switches may cause intermittent problems.
CAUTION
!
Installation
Installation:
1. Become familiar with concentric vent kit parts (see charts above).
2. Determine the best location for the termination kit.
3. Cut the recommended diameter hole for the nominal PVC pipe size called out in the charts above – Dim. “D”.
4. Partially assemble the vent kit by performing the following:
a. Cement concentric Y fitting to larger diameter pipe (see charts above).
b. Cement rain cap to smaller diameter pipe (see charts above).
