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.
4. A furnace installed in a residential garage must be installed so the burner and ignition source are located higher
than 18 inches above the floor, unless the required combustion air is taken from the exterior of the garage. Also, the
furnace must be located or protected to avoid physical damage by vehicles.
c
WARNING: This furnace is not to be used as a construction heater.

VHF-A** front clearance 6” for Closet, 24” for Alcove.
The minimum clearances listed in the preceding table are for fire protection. Clearance for servicing the front of the
furnace should be at least 24 inches. A clearance of 24 inches is recommended for passage to all points on the
furnace requiring service access.
NOTE: The VHF-A** furnaces may be installed on combustible flooring.
NOTE: The VHF-A** furnace is approved for closet installation. If the VHF-A** is installed in a closet, it requires
two openings in the closet door for combustion air, each having a minimum area of 162 sq. inches. This free area for
the VHF-A** intentionally exceeds the recommended minimum free area of 2 square inches per 1000 BTUH of
input rate.
