injury or death.
• This furnace must be installed in accordance with 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
specifi ed in Table 1 (page 6).
