Combustion Air Supply Requirements

The boiler requires a clean, fresh and adequate supply of combustion
air, failure to provide sufficient combustion air supply will result in
carbon monoxide (CO) production that could lead to personal injury
including loss of life or damage to boiler or property. Do not store any
flammable liquids, fluids, vapors or materials near the vicinity of the
boiler.
Special attention

Quality of combustion air

Dust, fumes, corrosive elements, hydrocarbons, other unknown
containments

Paint, beauty, automotive etc. shops
The flue gas vent pipe must be airtight and watertight. Horizontal
sections of the venting must slope downward towards the boiler ½"
per linear foot [42 mm/m] and adequate vent support must be
provided.
Room combustion air supply requirements
The boiler must be provided with an adequate combustion air supply,
the combustion air supply requirements must be determined and sized
in accordance to national and local codes having jurisdiction. CSA
B149 & ANSI Z223.1 – More than one combustion air source may be
required. An optional air intake filter should be fitted air intake housing
(recommendation).
Air supply venting materials
