GENERAL INFORMATION
DO NOT INSTALL THIS FURNACE
IN A MOBILE HOME!!
This furnace
is not approved for installation in a
mobile home. Doing so could cause
FIRE, PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
WHEN THIS FURNACE IS
INSTALLED IN A RESIDENTIAL
GARAGE, IT MUST BE INSTALLED
SO THE BURNERS AND IGNITION
SOURCE ARE LOCATED NO LESS
THAN 18 INCHES ABOVE THE
FLOOR. THIS IS TO PREVENT
THE RISK OF IGNITING
FLAMMABLE VAPORS WHICH
MAY BE PRESENT 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 EXPLOSION, RESULTING
IN PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
1.
IMPORTANT:
If installing the unit
over a finished ceiling or living
area, be certain to install an
auxiliary condensate drain pan
under the entire unit. This
auxiliary drain pan should extend
under any evaporator coil
installed 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:
a. be sure the air passes over
the heat exchanger before
passing over the cooling
coil. The cooled air passing
over the warm ambient air
inside the heat exchanger
tubes can cause
condensation inside the tubes
resulting in corrosion and
eventual failure.
b. install a parallel duct system
to divert all the air from the
furnace allowing it to pass
over the cooling coil only. Use
dampers or other means to
prevent chilled air from
passing over the heat
exchanger.
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:
Install the furnace
level. If it is not level, condensate
cannot drain properly, possibly
causing furnace shut down.
NOTE:
These furnaces are approved
for installation in attics, as well as
alcoves, utility rooms, closets and
crawlspaces. Provisions must be
made to prevent freezing of
condensate.
4.
IMPORTANT:
If this furnace is
installed in a garage, attic and/or
any unconditioned space, install a
self-regulating heat tape around
the condensate trap and along the
entire length of the condensate
drain in the unconditioned space.
When the condensing horizontal
gas furnace is installed in an
unconditioned space where the
temperature would be capable of
reaching close to or below 32°F
!
WARNING
!
WARNING
(0°C), a self-regulating heat tape
is required on the condensate
drain, along with an insulation
wrap. The heat tape should meet
the following requirements:
a. The heat tape must be UL
listed.
b. The heat tape must be
installed per the
manufacturer’s instructions for
the entire length of drain pipe
in the unconditioned space.
c. The heat tape should be rated
at 5 or 6 watts per foot at
120V
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.
5.
IMPORTANT:
If installing in a
utility room, be sure the door is
wide enough to:
a. allow the largest part of the
furnace to pass; or
b. allow any other appliance
(such as a water heater)
to pass.
c. allow service clearance
