Section 2 - Typical Boiler Room Layout
Section 3 - Boiler Room Air Requirements
Figure 1
1. To ensure safe efficient operation, the boiler system must be supplied with sufficient air for combustion and ventila-
tion (see Fig. 2)
2. Unless properly controlled, avoid the use of forced ventilation, since it can create an undesirable pressure differen-
tial between the boiler room and air source.
3. All boilers located in confined rooms should have free access to ventilation and combustion air from two perma-
nent openings. One opening should terminate within 12" of the ceiling, the other within 12" from the floor
(see Fig. 2). Each opening shall have at least 1 sq. inch free area per 1,000 BTU/HR of burner input. Openings should
freely connect with areas having adequate infiltration of outside air
WARNING: Failure to provide an adequate supply of fresh air for combustion will result
in hazardous operating conditions. Do not use an exhaust fan in the boiler room.
