ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

NOTE: Discharge static electricity accumulated in the body before touching the unit. An electrostatic discharge can adversely affect electrical components.

Use the following precautions during furnace installation and ser- vicing to protect the integrated control module from damage. By putting the furnace, the control, and the person at the same electro- static potential, these steps will help avoid exposing the integrated control module to electrostatic discharge. This procedure is appli- cable to both installed and non-installed (ungrounded) furnaces.

1.Disconnect all power to the furnace. Do not touch the integrated control module or any wire connected to the control prior to discharging your body’s electrostatic charge to ground.

2.Firmly touch a clean, unpainted, metal surface of the furnaces near the control. Any tools held in a person’s hand during grounding will be discharged.

3.Service integrated control module or connecting wiring following the discharge process in step 2. Use caution not to recharge your body with static electricity; (i.e., do not move or shuffle your feet, do not touch ungrounded objects, etc.). If you come in contact with an ungrounded object, repeat step 2 before touching control or wires.

4.Discharge your body to ground before removing a new control from its container. Follow steps 1 through 3 if installing the control on a furnace. Return any old or new controls to their containers before touching any ungrounded object.

III.PRODUCT APPLICATION

This furnace is primarily designed for residential home-heating applications. It is NOT designed or certified for use in mobile homes, trailers or recreational vehicles. This unit is NOT designed or certified for outdoor applications. The furnace must be installed indoors (i.e., attic space, crawl space, or garage area provided the garage area is enclosed with an operating door).

This furnace can be used in the following non-industrial commer- cial applications:

Schools, Office buildings, Churches, Retail stores Nursing homes, Hotels/motels, Common or office areas

In such applications , the furnace must be installed with the follow- ing stipulations:

•It must be installed per the installation instructions provided and per local and national codes.

•It must be installed indoors in a building constructed on site.

•It must be part of a ducted system and not used in a free air delivery application.

•It must not be used as a “make-up” air unit.

•It must be installed with two-pipe systems for combustion air, especially if VOC’s or other contaminants are present in the conditioned space.

•All other warranty exclusions and restrictions apply This furnace is an ETL dual-certified appliance and is appropriate for use with natural or propane gas (NOTE: If using propane, a propane conversion kit is required).

Dual certification means that the combustion air inlet pipe is op- tional and the furnace can be vented as a:

Non-direct vent (single pipe) central forced air furnace in which combustion air is taken from the installation area or from air ducted from the outside or,

Direct vent (dual pipe) central forced air furnace in which all combustion air supplied directly to the furnace burners through a special air intake system outlined in these instructions.

This furnace may be used as a construction site heater ONLY if the following conditions are met:

•The vent system is permanently installed per these installation instructions.

•A room thermostat is used to control the furnace. Fixed jumpers that provide continuous heating CANNOT be used.

•Return air ducts are provided and sealed to the furnace.

•A return air temperature range between 60ºF (16ºC) and 80ºF (27ºC) is maintained.

•Air filters are installed in the system and maintained during construction, replaced as appropriate during construction, and upon completion of construction are replaced.

•The input rate and temperature rise are set per the furnace rating plate.

•100% outside air is provided for combustion air requirements during construction. Temporary ducting can be used.

NOTE: Do not connect the temporary duct directly to the furnace. The duct must be sized according to the instructions under Section V, Combustion and Ventilation Air Requirements, Section 5.3.3.

•The furnace heat exchanger, components, duct system, air filters and evaporator coils are thoroughly cleaned following final construction clean up.

•All furnace operating conditions (including ignition, input rate, temperature rise and venting) are verified according to these installation instructions.

NOTE: The Commonwealth of Massachusetts requires that the following additional requirements must also be met:

•Gas furnaces must be installed by a licensed plumber or gas fitter.

•A T-handle gas cock must be used.

•If the unit is to be installed in an attic, the passageway to and the service area around the unit must have flooring.

To ensure proper installation and operation, thoroughly read this manual for specifics pertaining to the installation and application of this product.
