Refer to the furnace rating plate.
• Install this furnace only in a location and position as
specified on page 5.
• Provide adequate combustion and ventilation air to the
furnace space as specified on pages 6 - 10.
• Combustion products must be discharged outdoors.
Connect this furnace to an approved vent system only,
