2. Firmly touch a clean, unpainted, metal surface of the

furnaces near the control.  Any tools held in a  person’s
hand during grounding will be discharged.

3. Service integrated control module or connecting wiring

following the discharge process in step 2.  Use caution not to
recharge your body with static electricity; (i.e., do not move
or shuffle your feet, do not touch ungrounded objects, etc.).
If you come in contact with an ungrounded object, repeat step
2 before touching control or wires.

4. Discharge your body to ground before removing a new control

from its container.  Follow steps 1 through 3 if installing the
control on a furnace.  Return any old or new controls to their
containers before touching any ungrounded object.

III. PRODUCT APPLICATION

This furnace is primarily designed for residential home-heating ap-
plications.  It is NOT designed or certified for use in mobile homes,
trailers or recreational vehicles.  This unit is NOT designed or
certified for outdoor applications.  The furnace 

must 

be installed

indoors (i.e., attic space, crawl space, or garage area provided the
garage area is enclosed with an operating door).
This furnace can be used in the following non-industrial commercial
applications:

Schools, Office buildings, Churches, Retail stores
Nursing homes, Hotels/motels, Common or office areas

In such applications , the furnace must be installed with the following
stipulations:

It must be installed per the installation instructions provided
and per local and national codes.

It must be installed indoors in a building constructed on
site.

It must be part of a ducted system and not used in a free
air delivery application.

It must not be used as a “make-up” air unit.

It must be installed with two-pipe systems for combustion
air, especially if VOC’s or other contaminants are present
in the conditioned space.

All other warranty exclusions and restrictions apply This
furnace is an ETL dual-certified appliance and is appropriate
for use with natural or propane gas (

NOTE:  

If using

propane, a propane conversion kit is required).

Dual certification means that the combustion air inlet pipe is optional
and the furnace can be vented as a:

Non-direct vent (single pipe) central forced air furnace in
which combustion air is taken from the installation area or
from air ducted from the outside or,
Direct vent (dual pipe) central forced air furnace  in which
all combustion air supplied directly to the furnace burners
through a special air intake system outlined in these
instructions.

To ensure proper installation and operation, thoroughly read this
manual for specifics pertaining to the installation and application of
this product.

RECAUTIONS

NOTE:

  Discharge static electricity accumulated in the body before

touching the unit.  An electrostatic discharge can adversely affect
electrical components.
Use the following precautions during furnace installation and ser-
vicing to protect the integrated control module from damage.  By
putting the furnace, the control, and the person at the same electro-
static potential, these steps will help avoid exposing the integrated
control module to electrostatic discharge.  This procedure is appli-
cable to both installed and non-installed (ungrounded) furnaces.

1. Disconnect all power to the furnace.  Do not touch the

integrated control module or any wire connected to the control
prior  to discharging your body’s electrostatic  charge to
ground.
