10.6.1 Drain connection and blow-down valve
assembly
To enable the boiler to be drained quickly and, if
required, the boiler sludge to be removed, we
recommend a drain connection as shown in Fig. 56.

10.6.2 Walk-on boiler cover
As additional equipment, Bosch offers a walk-on boiler
cover. Also available with this are a ladder and safety rail
with toe board. The walk-on boiler cover is already fitted
when the boiler is delivered. The safety rail and ladder
are to be fitted on site. The ladder can be mounted on
the left hand or right hand side of the boiler. Please
specify which side when ordering the walk-on boiler
cover. In the case of gas combustion, the ladder should
be fitted opposite the gas train.
