ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
PROCEDURE
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. DO NOT TOUCH THE
CONTROL OR ANY WIRE CONNECTED TO THE CON-
TROL PRIOR TO DISCHARGING YOUR BODY’S ELEC-
TROSTATIC 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.
INTRODUCTION
The Model 58PAV, Series 160 Limited Furnace is available in
sizes 44,000 through 154,000 Btuh input capacities.
The design of the upflow gas-fired furnace is A.G.A./C.G.A.
certified for natural and propane gas and for installation on
combustible flooring, in alcoves, attics, basements, closets, or
utility rooms. The furnace is factory-shipped for use with natural
gas. A factory accessory gas conversion kit, as listed on the
furnace rating plate is required to convert furnace for use with
propane gas. The design of this furnace line is not A.G.A./C.G.A.
certified for installation in mobile homes, recreation vehicles, or
outdoors.
Before installing the furnace in the United States, refer to the
NFGC and NFPA 90B. For copies of the NFGC and NFPA 90B,
contact the National Fire Protection Association Inc., Battery-
march Park, Quincy, MA 02269; or for only the NFGC contact the
American Gas Association, 400 N. Capitol St., NW, Washington
DC 20001.
Before installing the furnace in Canada, refer to the NSCNGPIC.
For a copy of the NSCNGPIC, contact Standard Sales, CSA
International, 178 Rexdale Boulevard, Etobicoke (Toronto), On-
tario, M9W 1R3, Canada.
Installation must comply with regulations of serving gas supplier
and local building, heating, plumbing or other codes in effect in the
area in which installation is made. In absence of local building
codes, installation must conform with NFGC in the United States
and the NSCNGPIC and all authorities having jurisdiction in
Canada.
These instructions cover minimum requirements for a safe instal-
lation and conform to existing national standards and safety codes.
In some instances, these instructions exceed certain local codes
