3.6 Combustion Air and Ventila-
tion

WARNING
!
CARBON MONOXIDE POISIONING HAZARD!
VENTILATION REQUIRED!
OIL BOILER/BURNER COMBUSTION AIR OPE-
NING MUST NOT BE OBSTRUCTED OR BLOC-
KED. THESE OPENINGS SUPPLY COMBUSTION
AND VENTILATION AIR TO THE BOILER.
FAILURE TO FOLLOW THIS WARNING COULD
RESULT IN CARBON MONOXIDE POISONING OR
DEATH.
Important: All aspects of the installation of this
boiler, including materials, methods of providing
combustion air and methods of venting products of
combustion to the outdoors must comply with all local
codes and the following national standards:
1) CSA B139 (most recent edition) - Installation Code
for Oil Burning Equipment (Canada)
2) NFPA 31 (most recent edition) - Standard for the
Installation of Oil Burning Equipment (US)
3) NFPA 211 (most recent edition) - Standard for
Chimneys, Fireplaces, Vents, and Soild Fuel Burning
Appliances
Chloride, fl uoride, iodide, and bromide bearing com-
pounds when present, even in low concentrations, in
air supplied for combustion to the boiler, can result in
accelerated and severe corrosion of the heat exchan-
ger and/or the venting system. Often, household
chemicals contain chloride-bearing compounds. There
are many compounds representative of this classifi ca-
tion of chemicals. A few common examples are:
- Cleaning solvents
- Varnish and paint removers
- Bleaches
- Fabric softeners
- Water softener salt
Avoid storing or using these chemicals within close
proximity to the boiler. In addition, avoid storing or
using any chemicals, of an unknown and possibly
fl ammable nature, in close proximity to the boiler. If
it is necessary to store or use chemicals in the same
space as the boiler, the area should be well-ventilated
and all containers should be sealed when not in use.
If possible, keep chemicals in a separate, well ventila-
ted, room closed off from the boiler.
The boiler shall be installed in a location within the
building that permits a satisfactory supply of air for
combustion, ventilation, and proper operation of the
venting system. While all forms of building con-
struction cannot be covered in detail in this instal-
ler’s guide, this requirement may usually be met by
application of one of the following methods in ordi-
nary building construction. However, applicable local
