INSTALLATION
Step 1 — Plan for Unit Location
Select a location for the unit and its support system (curb or other)
that provides for the minimum clearances required for safety. This
includes the clearance to combustible surfaces, unit performance
and service access below, around and above unit as specified in
Fig. 3.
NOTE: Consider also the effect of adjacent units.
Be sure that unit is installed such that snow will not block the
combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on class A, B,
or C roof-covering material when roof curb is used.
Do not install unit in an indoor location. Do not locate air inlets
near exhaust vents or other sources of contaminated air.
Although unit is weatherproof, avoid locations that permit water
from higher level runoff and overhangs to fall onto the unit.
Select a unit mounting system that provides adequate height to
allow for removal and disposal of frost and ice that will form
during the heating-defrost mode as well as allow installation of
condensate trap per requirements. See Install External Condensate
Trap and Line on page 11 for required trap dimensions.
ROOF MOUNT
Check building codes for weight distribution requirements. Unit
operating weight is shown in Table 2.
Step 2 — Plan for Sequence of Unit Installation
The support method used for this unit will dictate different se
-
quences for the steps of unit installation. For example, on curb-
mounted units, some accessories must be installed on the unit be
-
fore the unit is placed on the curb. Review the following for rec
-
ommended sequences for installation steps.
NOTE: Unit is not designed to have overhead obstruction. Contact Application Engineering for guidance on any application planning overhead
obstruction or for vertical clearances.
