5.1.1 - Requirements for correct ventilation
The plant room MUST have a properly sized ventilation openings.
To ensure proper ventilation for combustion, high and low level
ventilation shall be installed. Where the appliance is installed
in an open-flue (B23) configuration, ventilation shall be directly
to outside andthe free area of openings shall be as detailed in
figure 5-2.
Room sealed appliances (type C) should be provided with
ventilation with free area as detailed in figure 5-2.
Low level ventilation shall be provided as low as practicable and
be within 1 m of the plant room floor for natural gas installations
and within 250 mm of the floor for LPG installations.
Further guidance on ventilation provision including the use
of mechanical ventilation systems can be found within IGEM/
UP/10 Edition 4.
WARNING!
There must never be negative
pressure in the heating unit. For this reason you must
take into account the presence of any outlet fans, ceiling
fans, dryers, compressors, air heating units, etc. that
might take air away from the boiler.
WARNING!
Extractors or similar devices for the
removal of air from the heating unit might reduce the
ventilation required for combustion and/or cause low
pressure in the ventilation system. Escapes of exhaust
gases from the ventilation system in an occupied
habitable room can cause a very dangerous situation
which must be corrected immediately.
5.1.2 - Prevent combustion air
contamination
Do not terminate vent/air in locations that can allow
contamination of combustion air.
WARNING !!! Contaminated combustion air will
damage the appliance.
Ensure the combustion air will not contain any of the following
contaminats.
Product that may contaminate the air combustion:
- Chlorinated waxes/cleaners;
- Chlorine-based swimming pool chemical;
- Calcium chloride used for thawing;
- Sodium chloride used for water softening;
- Refrigerant leaks;
- Paint or varnish removers;
- Hydrochloric acid/muratic acid;
- Cements and glues;
- Antistatic fabric softeners used in clothes dryers;
- Chlorine-type bleaches, detergents and cleaning solvents
found in household laundry rooms;
- Adhesives used to fasten building products and other similar
products;

Place of installation
Figure 5-2 Example of ventilation
NOTE 1: For LPG installations, ventilation must be be within 250 mm from floor
level.
NOTE 2: At least 20% of low-level ventilation allowance to be below 1000 mm
from floor level.
NOTE 3: At least 20% of high-level ventilation allowance to be above 85% of
maximum room height.
NOTE 4: Operation <50% of time = 2cm
