830CA: Installation, Start–Up, Operating and Service and Maintenance Instructions
INTRODUCTION
This 4-way multipoise Category I fan-assisted furnace is CSA
design-certified. A Category I fan-assisted furnace is an appliance
equipped with an integral mechanical means to either draw or force
products of combustion through the combustion chamber and/or heat
exchanger. The furnace is factory-shipped for use with natural gas.
This furnace is not approved for installation in mobile homes,
recreational vehicles, or outdoors. The furnace is not permitted to be
used for heating of buildings under construction. This furnace is
designed for minimum continuous return-air temperature of 60°F (16°C)
db or intermittent operation down to 55°F (13°C) db such as when used
with a night setback thermostat. Return-air temperature must not exceed
80°F (27°C) db. Failure to follow these return-air temperature limits may
affect reliability of heat exchangers, motors, and controls, see
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping brackets and materials before operating the
furnace.

ELECTROSTATIC DISCHARGE (ESD)
PRECAUTIONS PROCEDURE
1. Disconnect all power to the furnace. Multiple disconnects maybe
required. 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 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.
CAUTION
!
FURNACE RELIABILITY HAZARD
Improper installation or service of furnace may cause premature
furnace component failure.
Electrostatic discharge can affect electronic components. Follow the
Electrostatic Discharge Precautions Procedure listed below 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.
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.
