The indoor units must be installed so that
the ignition system components are
protected from water (dripping, spraying,
rain, etc.) during appliance operation and
service (circulator replacement, control
replacement, etc.).
3.
The appliance must be installed
on a level, non-combustible floor.
Concrete over wood is not considered a
non-combustible floor. Maintain required
clearances from combustible surfaces.
4.
For installation on a combustible
floor only when installed on
special base: Units installed over a
combustible floor must use the Special
Combustible Floor Base. The unit must be
centered on the base as shown in FIG. 1.
• Provide a base of hollow clay tile or
concrete blocks from 8" to 12" thick
and extending 24" beyond the sides.
• The blocks must be placed in line so that
the holes line up horizontally to provide a
clear passage through the blocks.

an optional vent cap. Instructions for
placement of the vent cap are included in
the venting section.
Outdoor models must not be installed
directly on the ground. The outdoor unit
must be installed on a concrete brick,
block or other non-combustible pad.
