5.7.1 Check openings for combustion air supply and venting
To ensure an adequate combustion air supply and venting of the heating
system, suitable measures must be taken in accordance with the
National Fuel Gas Code, NFPA 54 (ANSI Z223.1), Section 5.3, Air for
Combustion and ventilation, and the local building codes. In Canada the
regulations in accordance with CAN/CSA B 149.1 and 2 Installation
Codes apply.
NOTICE: Risk of boiler damage and malfunctions due to
missing or inadequate openings for combustion air and
venting of the installation location!
Inadequate venting of the boiler room may result in
excessive ambient temperatures. This can damage the
boiler.
Inadequate combustion air supply may cause faults.
▶ Make sure that air inlet and outlet vents are not
closed off or their size reduced and that they are
adequately dimensioned.
▶ Note that the boiler must not be operated until all
obstructions have been removed.
▶ Draw the owner's/operator's attention to any
deficiencies and the potential dangers
NOTICE: Boiler damage due to contaminated
combustion air.
▶ Never use cleaning agents containing chlorine and
never use halogenated hydrocarbons (as, for
example, contained in spray cans, solvents, cleaning
agents, paints and adhesives).
▶ Do not store or use these substances in the boiler room.
▶ Avoid excessive dust accumulation.
