OPTIONAL DIRECT VENT-AIR INTAKE TERMINAL GUARD

WARNING

The direct vent-air intake terminal is HOT while the water heater is
in operation. Do not touch. Keep children, combustibles, gasoline
and other liquids having flammable vapors away.

It is recommended that a vent-air intake terminal guard be installed when the
vent-air intake terminal is located where it can be touched accidentally, or
accessed by children. (See Figure 2).

A chain link or louvered fence may be used instead of the vent-air intake
terminal guard. Maintain proper clearances as specified in this instruction
manual to the vent-air intake terminal. (See Figure 3).
