ELECTROSTATIC DISCHARGE (ESD)
PRECAUTION
1. Disconnect all power to the furnace. DO NOT TOUCH THE
CONTROL OR ANY WIRE CONNECTED TO THE CONTROL
PRIOR TO DISCHARGING YOUR BODY’S ELECTROSTATIC
CHARGE TO GROUND.
2. Firmly touch a clean, unpainted, metal surface of the furnace
chassis which is close to the control. Tools held in a person’s hand
during grounding will be satisfactorily discharged.
3. After touching the chassis you may proceed to service the control or
connecting wires as long as you do nothing that recharges your
body with static electricity (for example; DO NOT move or shuffle
your feet, DO NOT touch ungrounded objects, etc.).
4. If you touch ungrounded objects (recharge your body with static
electricity), firmly touch furnace again before touching control or
wires.
5. Use this procedure for installed and uninstalled (ungrounded)
furnaces.
6. Before removing a new control from its container, discharge your
body’s electrostatic charge to ground to protect the control from
damage. If the control is to be installed in a furnace, follow items 1
through 5 before bringing the control or yourself into contact with
the furnace. Put all used AND new controls into containers before
touching ungrounded objects.
7. An ESD service kit (available from commercial sources) may also
be used to prevent ESD damage.
SECTION 2:
GENERAL - ALL ORIENTATIONS
INSTALL FURNACES
NOTE: Multipoise units can be installed in UPFLOW, DOWNFLOW,
or HORIZONTAL configurations.
Refer to furnace Installation, Start-Up, and Operating Instructions or
Product Specifications for appearance and dimensional drawing of
twinned furnaces and their connection locations.
NOTE: Follow all clearances for combustibles and service as shown in
the individual furnace installation instructions
1. Select two identical heating and airflow furnaces, see Table 1 .
2. Remove bottom closure panels from both furnaces, see Fig. 6 .
a. Remove main and blower access doors.
b. Remove screws from front filler panel, and bottom closure panel
(when used).
c. Rotate front filler panel downward to remove.
d. Remove bottom closure panel and set aside.
e. Reinstall front filler panel.
3. Apply two factory-supplied foam strips to mating side of one
furnace. Locate strips equal distance from top and bottom as shown
in Fig. 8 .
4. Refer to the appropriate orientation to install the furnaces.

UPFLOW INSTALLATION
NOTE: When the furnaces are positioned back-to-back, the external
extension harness cannot be used on the same side of the furnace that the
return air ducts connect to. Locate harness on opposite side of furnace
where return air is used.
1. Remove the 7/8 in. (22 mm) knockout in the mating side of each
furnace blower compartment. Remove one right side knockout
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in unit and component
damage.
Failure to follow this caution could result in unit and component
damage. Electrostatic discharge can affect electronic components. Take
Precautions during furnace installation and servicing to protect the
furnace electronic control. Precautions will prevent electrostatic
discharges from personnel and hand tools which are held during the
procedure. These precautions will help to avoid exposing the control to
electrostatic discharge by putting the furnace, the control and the person
at the same electrostatic potential.
