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 boiler room!
Inadequate venting of the boiler room may result in
excessive ambient temperatures. This can damage the
boiler.
Inadequate combustion air supply may cause
malfunctions in operation.
▶ Make sure that air inlet or outlet vents are not closed
off or their size reduced and that they are adequately
dimensioned.
▶ The boiler must not be operated until the obstruction
has been removed.
▶ Draw the operator's attention to any deficiencies and
the potential dangers.
