II. GENERAL INSTRUCTIONS - READ BEFORE START OF INSTALLATION

1.  The heating output capacity of the furnace proposed for installation should be based on a heat loss
calculation  made  according  to  the  manuals  provided  by  the  Air  Conditioning  Contractors  of  America
(ACCA)  or  the  American  Society  of  Heating,  Refrigeration  and  Air  Conditioning  Engineers,  Inc.
(ASHRAE).

2.  All local codes and/or regulations take precedence over the instructions in this manual and should be
followed accordingly. In the absence of local codes, installation must conform with these instructions and
regulations  of  the  National  Fire  Protection  Association,  and  to  the  provisions  of  the  National  Electrical
Code (ANSI/NFPA 70-1999 or latest edition).

3.  The installed furnace must be level and positioned in a central location with respect to outlet registers.
It should be located near the chimney to minimize any horizontal run of flue pipe, which may be required.

located  higher  than  18  inches  above  the  floor.  The  furnace  must  also  be  located  or  protected  to  avoid
physical damage by vehicles.
