The combustion air inlet filter kit is designed to filter dust and debris from the combustion air

to reduce burner clogging in dusty environments.

The filter is sized to fit inside a 4 inch diameter PVC pipe (supplied). For installations using 4”

PVC vent size, a straight 4” x 4” flexible plumbing pipe connector (Fernco 1056-44 or

equivalent) will be required to clamp over the outside of the filter flange and PVC pipe and

connect to the existing venting system. If the intake venting pipe is 3” diameter, then a 4” to

3” flexible plumbing pipe connector (Fernco 1056-43 or equivalent) will be required. This will

enable the pipe to be disconnected for filter inspection and cleaning.

CAUTION!

DO NOT CEMENT THE FILTER END OF THE PIPE TO THE VENTING SYSTEM.

USE ONLY A FLEXIBLE PLUMBING CONNECTOR WITH CLAMPS SO THE

FILTER CAN BE REMOVED FOR CLEANING AND SERVICING.

FOLLOW THE INSTALLATION INSTRUCTIONS INCLUDED WITH THIS WATER

HEATER FOR SPECIFIC REQUIREMENTS ON THE VENTING SYSTEM

INSTALLATI0N.

WARNING!

THE FILTER KIT WILL NOT ELIMINATE AIRBORNE CONTAMINANTS OR

POLLUTANTS.

PRE-INSTALLATION 1. Locate the air inlet filter as close as practical to the water heater. The filter may be installed in either a horizontal or vertical position to suit the installation of the air intake venting system. The filter will need to be inspected and cleaned or replaced periodically, so be sure the filter is located where it can be accessed for servicing. 2.

MAINTENANCE CAUTION! THE FILTER WILL REQUIRE PERIODIC INSPECTION, CLEANING, OR REPLACEMENT FOR PROPER OPERATION OF THE WATER HEATER. FAILURE TO CLEAN OR REPLACE A DIRTY FILTER WILL CAUSE THE WATER HEATER TO MALFUNCTION AND MAY DAMAGE COMPONENTS. INSPECT AND CLEAN AT REGULAR INTERVALS. 1. Inspect the filter at regular intervals for dirt build-up on the element. How often the filter needs cleaning will depend upon the environment and the location of the air intake terminal. 2.
