OPTIONAL VENT-AIR INTAKE SYSTEM INSTALLATIONS
Each Direct Vent Water Heater comes with one (1) vent-air intake “Kit C.”
Optional vent-air intake kits are available that can extend the horizontal length
and/or vertical height of the vent-air intake system.
Note: Additional kit(s) must be purchased for the horizontal length
requirements of the vent-air intake system if “Kit C,” which is included with the
water heater is used for extending the vertical height of the vent-air intake
system.
To find which vent-air intake kit(s) and instructions are correct for your
installation, follow the steps below and then order the appropriate kit(s):
1. Measure the vertical height “Y” required in your installation. Reference
the height in the applicable Table A under the column heading
“Vertical Height “Y” (See Fig. 1).”
2. Measure the horizontal length “X” required in your installation.
Reference the length in Table B under the column heading “Horizontal
Length “X” (See Fig. 2).”
