Plumbing Advice
Please read through the information given in “Important Information” (Page 3 of
these instructions) for the responsibilities and minimum requirements of the
installer. Please note any installations carried out by installers not meeting these
requirements will result in void product warranty and will not be supported by
Broseley Fires.
If connected to an unvented heating system, this appliance must (as a minimum) have the
following components installed on the system to ensure the safe operation of the
appliance. Please note these valves are NOT supplied as standard.
1) WATTS STS20 – Thermal discharge Valve
2) WATTS KSG 30 – Safety Pressure Relief Valve
3) Expansion Vessel comprising 7% of the total system volume
4) If connected in conjunction with a Gas Combination Boiler you will need a “Low Loss
Header” to link the boilers together; this will ensure that there is no conflict between the
two boilers. The low loss header should be sized and provided by the heating engineer.
