All installations and services must be performed by qualified service personnel. 
 
A. Codes and Clearances: 
 
The following items must be considered when choosing the size and location of 
the unit. 
 
1. 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 to these instructions and the guidelines of the 
National Fire Protection Association (NFPA). Two applicable NFPA installation 
codes are the National Electrical Code, ANSI/NFPA 70-1999, and Standard for 
the Installation of Oil-Burning Equipment, NFPA 31-1997. The latest editions of 
these codes should be consulted. 
 
2. The selection of a heating unit should be based on a rate of heat loss 
calculation for the residence according to the manuals provided by the Air 
Conditioning Contractors of America (ACCA) or the American Society of 
Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE). The 
heating capacity of the unit proposed for installation should meet or slightly 
exceed the rate of heat loss for the residence.  Oversizing should not exceed 
125% of the heat loss calculation. 
 
3. When installed, this unit should be level. If possible, it should be installed in a 
central location, with respect to outlet registers of the supply air ductwork. 
  
4. Definitions of "combustible" and "non-combustible" materials as presented in 
the 1996 version of the National Fuel Gas Code, ANSI Z223.1-1996/NFPA 70-
1996, are as follows: 
 
a. Combustible material: 
“...materials made of or surfaced with wood, 
compressed paper, plant fibers, or other materials that 
are capable of being ignited and burned. Such materials 
shall be considered combustible even though 
flameproofed, fire-retardant treated, or plastered.” 
 
b. Non-combustible material: 
“...material that is not capable of being ignited and 
burned; such as material consisting entirely of, or a 
combination of, steel, iron, brick, concrete, slate, 
asbestos, glass, and plaster.”
