GENERAL
Keep appliance area clear and free from combustible materials and flammable vapours and
liquids.
A competent person should check and ensure that the flue, its support and terminal, the ventilation to the boiler house,
safety valve, drain, pressure gauge etc. are in a serviceable and working condition and still comply with the relevant
standards and codes of practice, as detailed in Section 5: GENERAL REQUIREMENTS.
Servicing is recommended at intervals no greater than 12 months to aid trouble free operation. Even if a maintenance
schedule is determined to be less than annually, it is important that all controls and safety features are checked for
correct operation on an annual basis.
