AIR FOR COMBUSTION AND VENTILATION

Continued

Ventilation Air From Outdoors

Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code ANSI Z223.1/ NFPA 54, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts.

IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent. Any outside air ducts and/or ash dumps in the fireplace shall be permanently closed at the time of appliance installation.

INSTALLATION

NOTICE: This heater is intended for use as supple- mental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source.

WARNING: A qualified service person must in- stall fireplace insert. Follow all local codes.

WARNING: Make sure the selector switch is in the OFF position before installing heater

WARNING: Never install the fireplace insert

•in a bedroom or bathroom

•in a recreational vehicle

•where curtains, furniture, clothing, or other flam- mable objects are less than 42 inches from the front, top, or sides of the fireplace insert

•in high traffic areas

•in windy or drafty areas

CAUTION: This fireplace insert creates warm air currents. These currents move heat to wall surfaces next to fireplace insert. Installing fireplace insert next to vinyl or cloth wall coverings or operating fireplace insert where impurities (such as, but not limited to, tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may discolor walls or cause odors.

WARNING: Before installing in a solid fuel burn- ing fireplace, the chimney flue and firebox must be cleaned of soot, creosote, ashes, and loose paint by a qualified chimney cleaner.

Note: Your Vanguard fireplace insert is designed to be used in zero clearance installations. Wall or framing material can be placed directly against any exterior surface on the rear, sides, or top of your fireplace insert, except where standoff spacers are integrally at- tached. If standoff spacers are attached to your insert, these spacers can be placed directly against wall or framing materials.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing fireplace in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, pages 5 through 7.

IMPORTANT: Make sure the fireplace insert is level. If fireplace insert is not level, log set will not work properly.
