  basements, etc.) may require insulation of the    
  water piping and drain piping to protect against    
  freezing. The drain and controls must be easily    
  accessible for operation and service. Maintain    
  proper clearances as specified on the data plate.

All Air from Outdoors
Outdoor fresh air can be provided to a confined area either 
directly or by the use of vertical and horizontal ducts. The 
fresh air can be taken from the outdoors or from crawl or 
attic spaces that freely communicate with the outdoors. 
Attic or crawl spaces cannot be closed and must be 
properly ventilated to the outside. 
Ductwork must be of the same cross-sectional area as 
the free area of the opening to which they connect. The 
minimum dimension of rectangular air ducts...

10 The size of each of the two openings is determined by the 
method in which the air is to be provided. Refer to Table 
3 to calculate the minimum free area for each opening. 
Figures 5, 6, and 7 are typical examples of each method. 
Louvers and Grilles
In calculating free area for ventilation and combustion 
air supply openings, consideration must be given to the 
blocking effect of protection louvers, grilles, and screens. 
These devices can reduce airflow, which in turn may 
require larger openings...
