DANGER CARBON MONOXIDE POISONING HAZARD Special warning for installation of furnaces or air handling units in enclosed area such as garages, utility rooms or parking areas. Carbon monoxide producing devices (such as automobile, space heater, gas water heater, etc.) Should not be operated in enclosed areas such as unventilated garages or utility rooms because of the danger of carbon monoxide (CO) poisoning resulting from the exhaust emissions.

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.
Page 6: Location Requirements & Considerations
• 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 furnace operation, install, operate and maintain the furnace in accordance with these installation and operation instructions, all local building codes and ordinances.

cleaning solutions (such as perchloroethylene) printing inks paint removers varnishes hydrochloric acid cements and glues antistatic fabric softeners for clothes dryers masonry acid washing materials • Seal off a non-direct vent furnace if it is installed near an area frequently contaminated by any of the above substances. This protects the non-direct vent furnace from airborne contaminants.

IRECT INGLE IPING Non-direct vent installations require only a vent/flue pipe. The vent pipe can be run horizontally with an exit through the side of the building or run vertically with an exit through the roof of the building. The vent can also be run through an existing unused chimney; however, it must extend a minimum of 12 inches above the top of the chimney.

IRCULATOR LOWER PEEDS This furnace is equipped with a multi-speed circulator blower. This blower provides ease in adjusting blower speeds. The Specifica- tion Sheet applicable to your model provides an airflow table, showing the relationship between airflow (CFM) and external static pressure (E.S.P .), for the proper selection of heating and cooling speeds.

RIMARY IMIT The primary limit control is located on the partition panel and monitors heat exchanger compartment temperatures. It is a normally- closed (electrically), automatic reset, temperature-activated sensor. The limit guards against overheating as a result of insufficient conditioned air passing over the heat exchanger. UXILIARY IMIT The auxiliary limit controls are located on or near the circulator blower and monitors blower compartment temperatures.

ESETTING OCKOUT Furnace lockout results when a furnace is unable to achieve ignition after three attempts during a single call for heat. It is characterized by a non-functioning furnace and a fault code displayed. If the furnace is in “lockout”, it will (or can be) reset in any of the following ways.

ILTER EMOVAL Depending on the installation, differing filter arrangements can be applied. Filters can be installed in either the central return register or a side panel external filter rack (upflow only). A media air filter or electronic air cleaner can be used as an alternate filter. Follow the filter sizes given in the Recommended Minimum Filter size table to ensure proper unit performance.
