INSTALLATION
location. Failure to do so will void the warranty.
11. Particulate matter or chemicals (example: perchlorethylene, halogenated
compounds) in the combustion air supply to the boiler will cause damage
or failure to the burner and is not covered under warranty. High-risk
situations for particulate matter to be in the air include construction and
maintenance activities.
12. In Canada, for recommended practice, refer to CSAB1.
 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-confi ned space.
3. It is important to provide free access of air to the boiler. Per ASME Section
VI Para. 6.04 and NBIC, unobstructed air ventilation openings (one near
ceiling, one near fl oor) should be sized on the basis of one square inch
free area per 2000 BTU/HR (504.3 kcal/hr) maximum fuel input of the
combined burners located in the boiler room. This is subject to state and
local regulations.
4. Consistent proper ventilation of the boiler room is essential for good
combustion. Install two fresh air openings, one at a low level, 24” (610 mm).
5. Boiler room pressure must be neutral relative to the outdoors.
 Air Piped From Outside Boiler Room
Adhere to the following for installation:
1. The combustion air supply can be piped directly to the air inlet (Figure 11)
of the boiler.
2. A rubber air intake coupling is supplied with boilers specifi ed for
installation with ducted air supply. It must be used to connect the intake
piping to the boiler air inlet.
3. The air intake must be piped out of the building if the boiler room contains
contaminated air.
4. Air Intake pipes and fi ttings shall be Schedule 40 PVC pipe or smooth-
walled galvanized steel. Corrugated duct materials should not be used.
All Schedule 40 PVC pipe, fi ttings, primer and cement must conform to
American National Standard Institute and the American Society for Testing
and Materials (ANSI/ASTM standards.)
5. Intake PVC piping must be assembled using cement. This will ensure that
the intake is air tight and will not allow contaminates from the boiler room
into the boiler. The cement must be free fl owing and contain no lumps,

WARNING
The exhaust vent installer should be
familiar with Federal Codes as well
as local codes and regulations.
 Ð
CAUTION
To prevent the possible re-circulation
of fl ue gases, the vent designer must
take into consideration such things
as prevailing winds, eddy zones,
building confi gurations, etc. It is the
responsibility of the installer to locate
the exhaust duct in such a way that it
does not become blocked due to snow,
ice, and other natural or man-made
obstructions.
Do not locate the vent termination too
close to shrubbery as fl ue products may
stunt their growth or kill them.
