Myson Boiler Manuals

This page brings together Myson boiler manuals for the Apollo, Marathon, Combustion and Velaire ranges, across natural gas, oil and LPG models. More than half of the models link to a Myson boiler manual we have opened and checked against the model. Search by GC number works well here: most Myson GC numbers begin 41-494, 41-789 or 42-494, and the code is on the boiler data badge.
