clearances
(see WARNING
below)
If any clearance is less than in Figure 1, pro-
vide openings for combustion and ventilation
air located on the wall or door opposite the
boiler FRONT (see Figure 2)
These openings must be located as shown in Figure 2 to provide
proper air flow around the boiler. The free area of each opening
(after deducting for louvers) must be at least
1,000 Btuh of boiler input. If the building is of unusually tight
construction (see page 11 for definition), the air openings must
connect directly to outside or the building must have air openings
to the outside as specified on page 11.
If clearances are equal to or greater than Figure 1, see pages 10 and
11 for location and sizing of combustion air openings.
Failure to comply can result in severe personal injury, death or
substantial property damage and reduced boiler life.
Required MINIMUM clearances
Never install the boiler in a space with clear-
ances less than the minimum clearances
