2) FILLING THE BOILER
The boiler is filled with water through the safety valve bush, housed
on top of the boiler under the dome nearest the cab. This painted
brass dome is a substantial and heavy item, being turned from
solid brass. Care is needed when removing the dome, especially
when the engine is hot, as the dome itself will be hot. Take care not
to drop the dome onto the locomotive, as the weight of it may
damage the model. Lift off the dummy steam dome and then
remove the safety valve by unscrewing it using the knurled ring at
its base. Fill the boiler right to the top with clean water. Distilled
water is recommended if available. As an alternative to distilled
water if this is unavailable, clean tap water can be used in soft
water areas. Also, rain water or water from a dehumidifier can be
used provided that it is adequately filtered
Do not use deionised water as this type of water may cause long
term damage to the boiler and fittings.
There has to be a space above the water to allow steam to be
raised so, insert the end of the plastic pipe into the boiler and
withdraw 30ml of water with the syringe. Replace the safety valve
finger tight.
