ventilation outlet.
• The fans shall be selected and controlled so as to not cause a negative pressure (relative to the outside atmosphere)
developing in the boiler room.
• Interlocked to the gas appliance.

NOTES
1. It is most important that the correct concentration of the
water treatment products is maintained in accordance with the
manufacturers' instructions.
2. If the boiler is installed in an existing system any unsuitable
additives MUST be removed by thorough cleansing. BS
7593:2006 details the steps necessary to clean a domestic
heating system.
3. In hard water areas, treatment to prevent lime scale may be
necessary - however the use of artificially softened water is
NOT permitted.
4. Under no circumstances should the boiler be fired before
the system has been thoroughly flushed.
