Fig. 1 -- Multipoise Furnace in Upflow Orientation
GENERAL
This furnace can be installed as a direct vent (2--pipe) or an
optional ventilated combustion air condensing gas furnace. These
instructions are written as if the furnace is installed in an upflow
application. An upflow furnace application is where the blower is
located below the combustion and controls section of the furnace,
and conditioned air is discharged upward. Since this furnace can
be installed in any of the 4 positions shown in Fig. 2, you may
need to revise your orientation to component location
accordingly.

ELECTROSTATIC DISCHARGE (ESD)
PRECAUTIONS
UNIT DAMAGE HAZARD
Failure to follow this caution may damage furnace
components.
Failure to follow this caution may damage furnace
components. 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.
CAUTION
!
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.
CARE AND MAINTENANCE
For continuing high performance and to minimize possible
furnace failure, it is essential that maintenance be performed
annually. Consult your local dealer for maintenance and
maintenance contract availability.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Turn off the gas and electrical supplies to the unit before
performing any maintenance or service. Follow the
operating instructions on the label attached to the furnace.
