1. Open hand hole cover A.
2. Fully drain the boiler.
3. Clean the water chamber (hose it
out) and remove deposits via the
blow−down valve and drain. In
case of harder deposits which
cannot be removed by hosing
down, carry out a chemical
cleaning process using added
descaler.
4. Clean all sealing faces on closures,
and replace gaskets, where
required. Retighten new gaskets
after commissioning and recheck
after 24 hours.
