these instructions, all applicable local building codes
and the current revision of the National Fuel Gas Code
(NFPA54/ANSI Z223.1) or the Natural Gas and Propane
Installation Code, CAN/CGA B149.1.
• Useonlywithtypeofgasapprovedfor thisfurnace.
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,
as specified on pages 9 - 10.

• Thisfurnaceisdesignedtooperatewithamaximum
external pressure rise of 0.5 inches of water column.
Consult Tables 3 & 4 (pages 27 - 29), and the rating
plate for the proper circulating air flow and temperature
rise. It is important that the duct system be designed to
handle the desired flow rate and temperature rise. An
improperly designed duct system can result in nuisance
shutdowns, and comfort or noise issues.
