ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
PROCEDURE
FURNACE RELIABILITY HAZARD
Improper installation or service of furnace may cause prema-
ture furnace component failure.
Electrostatic discharge can affect electronic components.
Take precautions during furnace installation and servicing to
protect the furnace electronic control. Precautions will pre-
vent 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 DIS-
CHARGING YOUR BODY’S ELECTROSTATIC CHARGE
TO GROUND.
2. Firmly touch the 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 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 (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 4 before bringing the control
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.
LOCATION
GENERAL
Some assembly and modifications are required when used in any
of the four applications shown in Fig. 4.
This furnace must:
• be installed so the electrical components are protected from
water.
• not be installed directly on any combustible material other than
wood flooring (refer to SAFETY CONSIDERATIONS).
• be located close to the chimney or vent and attached to an air
distribution system. Refer to Air Ducts section.
• be provided ample space for servicing and cleaning. Always
comply with minimum fire protection clearances shown on the
furnace clearance to combustible construction label.
