Intent 1:
To limit the probability that the installation of
fuel-fired appliances that are not designed for the application will
lead to:
- performance that is significantly below expectations,
which could lead to:
- an inadequate delivery of warm air, which could lead
to an inability to maintain adequate indoor air temperatures, or
- inadequate ventilation, which could lead to the inadequate
control of:
- airborne pollutants, or
- relative humidity, which could lead to condensation,
which could lead to the growth of mould and mildew, or
- blockage of vents by ice or snow, which could lead to
an inability to vent combustion products, which could lead to the
entry of combustion products into occupied space.
This is to limit the probability of negative effects on
the air quality of indoor spaces, which could lead to harm to persons.
