ANNUAL inspections of the furnace and it's vent / combustion air supply is strongly recommended. It
is 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 SAFE
OPERATION OF
INSTRUCTIONS IN THIS SECTION. EACH VENT AND COMBUSTION AIR SUPPLY PIPE MUST
SERVE ONLY ONE APPLIANCE. DO NOT CONNECT TO AN EXISTING VENT OR CHIMNEY.
These furnaces are a condensing type appliance. The products of combustion are recirculated
through a secondary coil. During this process the flue products are brought to a point below dew
point. Thus the moisture present in the flue products condense leaving a liquid by-product. This by-
product must be removed from the furnace and it's collection system.
