Some local codes may require a vent cap cover. Figure 9 shows the optional wire vent cap protector available from the water heater manufacturer.
A wire mesh chain link fence (see Figure 9) may be used instead of the factory cover. Care should be taken to maintain adequate ventilation around the vent cap. If a chain link fence is installed, it must not be used as a storage area for items that may block proper ventilation.

Optional Wire Grill
When the water heater vent cap is low enough to be touched accidentally, or is accessible to small children, installation of a protective vent cover is recommended. See Figure 9.

Flue Extensions
There are three optional extension kits available. Any combination of the three kits can be chosen; however, only one kit can be used vertically and/or horizontally, see Figures 10 & 11.
Unless otherwise specified at the time of ordering, a standard exten- sion kit (9000687) is individually packaged and shipped within the water heater carton.
