Recommissioning the heating system

This section describes the commissioning procedure
using the programming unit's basic control panel.
To ensure safe operation of the heating system and to test
specific performance indicators, the burner/gas valve unit
fitted in the boiler have been factory-tested as described
in detail in ANSI Z21.13 and CGA 4.9.
Danger: Risk of fatal injury from electric cur-
rent when appliance is opened up.
V Before opening the boiler:Disconnect the
heating system from the electrical power
supply by means of the emergency stop
switch or the relevant circuit breaker on
the main fuse board.
V Take measures to ensure the heating sys-
tem can not be switched on again uninten-
tionally.
V After completing the work described below, fill out the
commissioning log ( Section 7.20, page 54).
Caution: Risk of boiler damage due to ex-
cessive dust and airborne debris levels.
V Do not operate the boiler when there is a
lot of dust in the boiler room, e.g. due to
building work.
V An air filter must be fitted if the supply of
combustion air contains large quantities of
dust (e.g. from unpaved roads and tracks
or dusty workplaces such as quarries,
mines, etc.) or airborne seeds from plants.
Warning: Risk of boiler damage from con-
taminated combustion air.
V Do not use cleaning agents that contain
chlorine or halogenated hydrocarbons
(e.g. in spray cans, solvents and cleaning
agents, paints, glues).
V Do not store or use such substances in
the boiler room.
V If the burner has become dirty as a result of
building work, it must be cleaned before being
commissioned.
V Inspect flue and combustion air piping and the
vents for combustion air supply and ventilation
( Section 5, page 20).
