All installations and services must be performed by qualified service personnel. 

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.

WARNING: This furnace is not to be used as a construction heater.  

 
5. Listed below are definitions of "COMBUSTIBLE MATERIAL" and "NON-COMBUSTIBLE MATERIAL." 
 
COMBUSTIBLE MATERIAL: 
Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or other material that will ignite 
and burn, whether flame resistant or not. 
 
NON-COMBUSTIBLE MATERIAL: 
Material  that  is  not  capable  of  being  ignited  and  burned.    Such  materials  consist  entirely  of,  or  a  combination  of, 
steel, iron, brick, tile, concrete, slate, or glass.

 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.
