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 5.3,
Air for combustion and ventilation.
2. The boiler room must meet the NFPA criteria for a non-con ned space.
3. It is important to provide free access of air to the boiler. To burn fuel
properly, it requires one square inch opening of fresh air for every 1,000
BTU input of fuel (no greater than 100 square inches).
4. Consistent proper ventilation of the boiler room is essential for good
combustion. Install two fresh air openings, one at a low level, within 12
inches (305 mm) from the oor but not less than 3 inches (76 mm), and
one at a higher level within 12 inches (305 mm) of the ceiling but not less
than 3 inches (76 mm) in the boiler room wall. This will provide a ow of
air to exhaust the hot air from the boiler room. Each opening must have a
minimum of 1in per 1000 Btu/hr and be no less than 100in

5. Consider the blocking e ect of louvers and grills.
Combustion Air Piped From Outside Building Without Sealed
Combustion
Adhere to the following for installation:
1. If the boiler room is deemed a con ned space two permanent ducts
connected to the outdoors must be installed.
NOTE: Assembly should be completed within 20 seconds after last application of
cement. Do not use a hammer to insert pipe.
2. After assembly, wipe excess cement from pipe at end of tting socket.
A properly made joint will show a bead around its entire perimeter. Any
gaps may indicate a defective assembly due to insu cient cement. Handle
joints carefully until completely set. Galvanized steel joints should be
sealed with adhesive aluminum tape.

Air Piped From Outside Boiler Room

Adhere to the following:
1. The combustion air supply can be piped directly to the air inlet (Figure 3) of
the boiler.
2. A rubber air intake coupling is recommended with boilers speci ed for
installation with ducted air supply. It must be used to connect the intake
piping to the boiler air inlet. This rubber air inlet coupling is available from
Fulton as an option.

regulations.
Do not use the boiler/burner as
support for ducted air piping.
Ducted piping must be supported
independently of the boiler.
Do not terminate venting into an
enclosed area.
Foreign substances, such as
. combustible volatiles in the
2
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.
Regular maintenance of the
lter is required (as per the lter
manufacturer's recommendations) to
maintain the warranty.
Particulate matter or chemicals in
the combustion air supply to the
boiler will cause damage or failure to
the burner and is not covered under
warranty.
