INSTALLATION BASE
The heater should be mounted on a level, non-combustible surface. Heater must not be installed on
carpeting. The heater can be installed on a combustible surface only when the appropriate listed floor shield base
is provided. An optional listed floor shield base is available for factory installation with the heater on all indoor
models. Do

use the shipping base crate as an installation base.
NOTE:
The heater should be located in an area where water leakage will not result in damage to the area adjacent

drain pan, adequately drained, be installed under the appliance. The pan must not restrict air flow.
In addition, the heater shall be installed such that the gas ignition system components are protected from water
