NOTE
Please ensure that the gas supply and main power supply is isolated before any maintenance work is carried out on
the boiler. Care should be taken when stripping the boiler for maintenance making sure that all parts, nuts, washers
and gaskets, etc. are kept safe, clean and dry for re-assembly. Following maintenance/cleaning, the boiler should be
re-assembled in the reverse order re-placing gaskets and joints where found necessary.
11.1 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. Check
the air inlet weekly if unit is operating in a construction zoon. Every 2 months in regular base.
Special attention:
- Quality of combustion air
- Dust, fumes, corrosive elements, hydrocarbons, other unknown containments
- Paint, beauty, automotive etc.
WARNING
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 [12mm] and adequate vent support must be provided.
11.2- Room combustion air supply requirements:
Category IV [Side wall] Applications:
A horizontal vent system with the sir supply, required for combustion, provided within the boiler room or combustion
air sources provided into the room. Min thickness of wall can be 2” and maximum 24”.
Direct Vent or Seal Combustion System Applications:
A vertical or horizontal venting system for both, the flue gases and combustion air at same termination and pressure
level. Minimum Thickness of the wall shall be can be 2” Maximum 24”
11.3- Vent Termination Inlet/Outlets
The vent terminals must be installed to provide suitable protection against wind, rain, snow or blockage along with a
See 7.7 for other requirements. Conventional chimney application rodent/debris screen. tapered cone, and sidewall or
direct vent require a termination TEE fitting. 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 maybe required. An optional filter should
be fitted air intake housing.
