INSTALLATION
!
WARNING
Do not terminate venting into an
enclosed area.
Never use open ame or smoke from
a cigarette, cigar, or pipe as a testing
method during boiler installation,
operation, or maintenance.
Foreign substances, such as
combustible volatiles in the
combustion system can create
hazardous conditions. If foreign
substances can enter the air stream,
the boiler combustion air inlet must
be piped to an outside location.
2-24
4. Particulate matter (example: sheetrock, berglass, cement, plaster board,
dirt, dust, lint) or chemicals (example: chlorine, sulfur, freon, uorine,
perchlorethylene, halogenated compounds) in the combustion air supply
to the boiler will cause damage or failure to the heat exchanger and/
or burner, and is not covered under warranty. High-risk situations for
particulate matter to be in the air include construction and maintenance
activities. See Table 5.
–
NOTE:
Pool and laundry room air may be contaminated with chlorine or uorine
compounds. If allowed to enter the combustion air supply, these contaminants
will signi cantly increase the acidity of ue gas condensate, potentialy damaging
heat transfer surfaces. Damage to the heat exchanger due to poor combustion air
quality is not covered under warranty.
5. Ensure there is not negative pressure in the boiler room. The boiler room
pressure must be neutral relative to the outdoors.

ƒ Combustion Air Supply From the Boiler Room
Adhere to the following for installation:
1. Adequate combustion air and ventilation must be supplied to the boiler
room in accordance with local codes and NFPA54/ANSI Z233.1, Section
9.3, Air for Combustion and Ventilation or CSA-B149.1 for Canada. The
minium net free area requirements in Table 6 may not supersede local and
jurisdictional codes and regulations where there codes and regulations
require an openingQ of greater net free area. The boiler room must meet
the NFPA criteria for a non-con ned space. See Figure 23.
2. Verify combustion air is taken from the outdoors and not from the inhabited
or occupied spaces within the building. Ensure space and nearby products
are evaluated for the potential of combustion air contaminants. See Table 5.
3. For installations providing two permanent openings directly
communicating with the outdoors, the minimum net free area of each
opening is 1 in per 4,000 BTU/hr of the total input capacity of the
combined burners located in the boiler room. Ensure a high opening
commences within 12 inches of the ceiling, and a low opening commences
within 12 inches of the oor. See Table 6.
4. For installations providing a single permanent opening directly
communicating with the outdoors, the minimum net free area of the
opening is 1 in per 3,000 BTU/hr of the total input capacity of the
combined burners located in the boiler room. See Table 6.
