ELECTROSTATIC DISCHARGE (ESD)
PRECAUTIONS PROCEDURE
CAUTION
!
FURNACE RELIABILITY HAZARD
Failure to follow this caution may result in unit 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.
1. Disconnect all power to the furnace. Multiple disconnects
may be required. DO NOT TOUCH THE CONTROL
OR ANY WIRE CONNECTED TO THE CONTROL
PRIOR
TO
DISCHARGING
ELECTROSTATIC CHARGE TO GROUND.
2. Firmly touch the clean, unpainted, metal surface of the fur-
nace chassis which is close to the control. Tools held in a
person's hand during grounding will be satisfactorily dis-
charged.
3. After touching the chassis, you may proceed to service the
control or connecting wires as long as you do nothing to
recharge 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 (and recharge your body
with static electricity), firmly touch a clean, unpainted metal
surface of the furnace again before touching control or
wires.
5. Use this procedure for installed and uninstalled (ungroun-
ded) 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 4 before bringing the con-
trol or yourself in 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.

PERSONAL INJURY AND/OR PROPERTY
DAMAGE HAZARD
Improper use or installation of this furnace may result in
premature furnace component failure. Unless otherwise
prohibited, this gas furnace may be used for heating
buildings under construction provided that:
- -The furnace is permanently installed with all electrical
wiring, piping, venting and ducting installed according to
these installation instructions. A return air duct is provided,
sealed to the furnace casing, and terminated outside the
space containing the furnace. This prevents a negative
pressure condition as created by the circulating air blower,
causing a flame rollout and/or drawing combustion
products into the structure.
- -The furnace is controlled by a thermostat. It may not be
"hot wired" to provide heat continuously to the structure
without thermostatic control.
- -Clean outside air is provided for combustion. This is to
minimize the corrosive effects of adhesives, sealers and
other
entrainment of drywall dust into combustion air, which can
cause fouling and plugging of furnace components.
- -The temperature of the return air to the furnace is
maintained between 55_F (13_C) and 80_F (27_C), with
no evening setback or shutdown. The use of the furnace
while the structure is under construction is deemed to be
intermittent operation per our installation instructions.
- -The air temperature rise is within the rated rise range on
the furnace rating plate, and the gas input rate has been set
to the nameplate value.
- -The filters used to clean the circulating air during the
construction process must be either changed or thoroughly
cleaned prior to occupancy.
- -The furnace, ductwork and filters are cleaned as necessary

to remove drywall dust and construction debris from all
HVAC system components after construction is completed.
- -Verify proper furnace operating conditions including
ignition, gas input rate, air temperature rise, and venting
according to these installation instructions.
