Itis the contractor’s responsibility to inform the user of this importance.All venting shall be in accordance with Part 7, Venting of Equipment, of the National Fuel Gas Code,ANSI Z223.1, or applicable local building and / or air conditioning codes.PROPER INSTALLATION OF THE VENT / COMBUSTION AIR SYSTEMS IS CRITICAL TO SAFEOPERATION OF THIS APPLIANCE. CAREFULLY READ AND UNDERSTAND THEINSTRUCTIONS IN THIS SECTION. EACH VENT AND COMBUSTION AIR SUPPLY PIPE MUSTSERVE ONLY ONE APPLIANCE. DO NOT CONNECT TO AN EXISTING VENT OR CHIMNEY.These furnaces are a condensing type appliance. The products of combustion are recirculatedthrough a secondary coil. During this process the flue products are brought to a point below dewpoint. Thus the moisture present in the flue products condense leaving a liquid by-product. This byproductmust be removed from the furnace and it’s collection system.IO-176 9
