EQUIPMENT BASE
The heater should be mounted on a level, structurally sound surface. The heater is approved for installation on a combus-
tible surface but must NEVER be installed on carpeting. Gas fueled equipment installed in enclosed parking garages must be
located at least 18 in. above the floor.
CAUTION:
The heater should be located in an area where water leakage will not result in damage to the
area adjacent to the appliance or to the structure. When such locations cannot be avoided, it is
recommended that a suitable catch 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 (dripping,
spraying, rain, etc.) during appliance operation or service (circulator replacement, control replacement, etc.).
