Location Requirements; Freeze Protection - Rheem *96V series Installation Instructions Manual

GENERAL INFORMATION
W RNING
WHEN THIS FURNACE IS INSTALLED IN A RESI-
DENTIAL GARAGE, IT MUST BE INSTALLED SO THE
BURNERS AND IGNITION SOURCE ARE LOCATED
NO LESS THAN 18 INCHES [450MM] ABOVE THE
FLOOR. THIS IS TO PREVENT THE RISK OF IGNIT-
ING FLAMMABLE VAPORS WHICH MAY BE PRES-
ENT IN A GARAGE. ALSO, THE FURNACE MUST BE
LOCATED OR PROTECTED TO AVOID PHYSICAL
DAMAGE BY VEHICLES. FAILURE TO FOLLOW
THESE WARNINGS CAN CAUSE A FIRE OR EXPLO-
SION, RESULTING IN PROPERTY DAMAGE, PER-
SONAL INJURY OR DEATH.
1. IMPORTANT: If installing the unit over a finished ceil-
ing or living area, be certain to install an auxiliary con-
densate drain pan under the entire unit. This auxiliary
drain pan should extend under any evaporator coil in-
stalled with the furnace and the open portion of the
condensate drain assembly. See "Condensate
Drain/Neutralizer" section for more details.
2. IMPORTANT: If using a cooling evaporator coil with
this furnace, be sure the air passes over the heat ex-
changer before passing over the cooling coil. The
cooled air passing over the warm ambient air inside
the heat exchanger tubes can cause condensation in-
side the tubes resulting in corrosion and eventual fail-
ure.
If these are manual dampers, they must be equipped to
prevent heating or cooling operation unless the damper is
in the full heat or cool position.
3. IMPORTANT: Furnace must be installed level from
front-to-back or with a slight tilt such that the back of
the furnace is up to 1/2" higher than the front of the
furnace as shown in Figure 3.
NOTE: These furnaces are approved for installation in at-
tics, as well as alcoves, utility rooms, closets and crawl-
spaces. Provisions must be made to prevent freezing of
condensate.

FREEZE PROTECTION

For installations where the furnace may reach tempera-
tures below 32°F (0°C) (such as an alcove or attic installa-
tion), the installer must take precautions to ensure that the
drain trap and connected drain pipe do not freeze. Local
codes and practices should be followed in order to prevent
freezing.
If the drain trap is installed within the furnace cabinet, no
freeze protection is required. When the trap is mounted
outside or partially outside the cabinet, it must be pro-

tected from freezing. Regardless of the location of the
drain trap, any exposed drain piping must be protected
from freezing as required by local practices or codes. A UL
or CSA listed heat tape or UL or CSA approved heating
cable with a rating of 3-6 watts per foot is acceptable pro-
tection when installed and maintained in accordance with
the manufacturer's instructions. Good installation practices
necessitate that the installer verify heat tape operation in
accordance with the manufacturer's instructions at the
time of installation.
IMPORTANT: Support this unit when installed. Since this
furnace is suitable for attic or crawl space installation, it
may be installed on combustible wood flooring or by using
support brackets.
