DIRECT-VENT

Sure Shot

®

Direct-Vent Water Heaters are shipped with Standard Vent Kit #9000687, which

allows for horizontal vent extension (back of water heater to inside wall plus wall thickness) up
to 10˝ on 40- and 50-gallon models, and up to 7-3/8˝ on the 75-gallon model. Standard Vent Kit
#9000687 adds 15˝ to the total height of the installation (floor to top of vent pipe).

Optional Vent Extension Kits (#9001246, #9001247 and #9001248) can be ordered for use when
longer horizontal vent extension or higher vertical vent extension are required, as shown in the
chart below.

If SMR “S99” is ordered, the vent kit will ship prior to the water heater. One of the vent kits below must be ordered at the same time as the heater.
