ELECTROSTATIC DISCHARGE (ESD)
PRECAUTIONS PROCEDURE
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
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
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.
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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

PERSONAL INJURY AND/OR PROPERTY
DAMAGE HAZARD
Improper use or installation of this furnace may result in premature
furnace component failure. 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 construction materials.
It also prevents the 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.

CARBON MONOXIDE POISONING / COMPONENT
DAMAGE HAZARD
Failure to follow this warning could result in personal injury or death
and unit component damage.
Corrosive or contaminated air may cause failure of parts containing flue
gas, which could leak into the living space. Air for combustion must not
be contaminated by halogen compounds, which include fluoride,
chloride, bromide, and iodide. These elements can corrode heat
exchangers and shorten furnace life. Air contaminants are found in
aerosol sprays, detergents, bleaches, cleaning solvents, salts, air
fresheners, and other household products. Do not install furnace in a
corrosive or contaminated atmosphere. Make sure all combustion and
circulating air requirements are met, in addition to all local codes and
ordinances.
