The intern
35、al diameter of the outside connection of the condensate discharge system shall be at least 13 mm. The disposal system, forming part of the boiler or supplied with the boiler, shall be such that: it can be easily inspected and cleaned in accordance with the manufacturers instructions; it cannot trans

S
37、urfaces in contact with condensate (except purpose provided drains, water traps and siphons) shall be designed to prevent condensate retention. 5.3 Chemical composition of the condensate The manufacturer shall communicate the probable chemical composition of the condensate (pH, heavy metals, etc.) i
38、f the composition is required by national regulations. 5.4 Control of the combustion products temperature If the combustion products circuit contains materials that are likely to be affected by heat or is intended to be connected to a flue (including seals) that is likely to be affected by heat from
