INTRODUCTION
This Installation Manual is applicable to the following models from the Potterton Myson Economist
range of gas boilers:
WM15/30 BFa
G.C. No. 41.838.90
WM30/40 BF
G.C. No. 41.838.82
WM40/50 BF
G.C. No. 41.838.85
These are balanced flue, wall mounted, central heating boilers, for use on natural gas only.
They require pumped circulation and cannot be used on gravity circulations. A bypass must always be
fitted into the heating system, across the boiler. A pump overrun thermostat is fitted as standard and a
permanent live connection to the boiler is required.
They may be range rated to suit individual heating systems.
Myson Ltd, pursues a policy of continuing improvement in design and performance of its products. The
right is therefore reserved to vary specification without notice.
