Requirements
on filling
The quality of the filling and any refilling water is important and must be of
water sufficient quality to maintain the following requirements:
pH 8 - 9.5
Maximum hardness between 8 and 12 grammes of calcium carbonate per 100
litres of water.
We strongly recommend that the system is chemically cleaned and then
dosed with a good quality corrosion and scale inhibitor before the boiler is
first fired. The boiler is guaranteed against material and manufacturing defects
however, failures or problems brought about by inadequate water quality are
expressly excluded from any guarantee or warranty and will render the
guarantee on the product void.
