8.3 Plantroom Combustion Air
Being a type B23 type, combustion air is brought into the S-FX boiler from the installation room. The following
conditions and considerations must be followed.
• The equipment room MUST be provided with properly sized openings to assure adequate combustion air in
accordance with the BS / IGEM standards. These vents must be open and not be closed or blocked.
• There will be a noticeable increase in the noise level during normal operation from the inlet air opening.
• Vent system and terminations must comply with the standard venting instructions set forth in this manual.
8.3.1 A
IR CONTAMINATION
Pool and laundry products and common household and hobby products often contain fluorine or chlorine
compounds. When these chemicals pass through the boiler, they can form strong acids. The acid can eat through
the boiler wall, causing serious damage and presenting a possible threat of flue gas spillage or boiler water leakage
into the building.
Please read the information given in the list below, with contaminants and areas likely to contain them. If
contaminating chemicals will be present near the location of the boiler combustion air inlet, have your installer pipe
the boiler combustion air and vent to another location, per this manual.
The boiler may never be located in a laundry room or pool facility, for example, these areas
will always contain hazardous contaminants.
To prevent the potential of severe personal injury or death, check for areas and products
listed in the list below, with contaminants before installing the boiler or air inlet piping.
If contaminants are found, you MUST: - remove contaminants permanently.
or - relocate air inlet and vent terminations to other areas.
The installation room has to have sufficient air supply vents. These vents must be open and
may not be closed or blocked. Requirements in accordance with national and local standards.
