6. OPERATION
Read this section of the manual with great care and get
an installer to explain the heat producing system in all
its different aspects: regulation and control.
If you suspect that the boiler or other part of the
system is frozen, do not start the system.
Please also note the operating conditions described in
chapter 5.
Note for Melbury HE 3800-10000: The boiler door
screws on the side of the axis of rotation must NOT
be loosened!
6.1. Commission
Before commissioning the system, please check:
- Whether the burner and the fuel system have been
checked and the settings of the burner correspond to
the required performance of the unit. Observe the
instructions for putting the burner into operation,
- Whether any foreign matter has been removed from
the boiler furnace,
- Whether the turbulators have been properly installed,
- Whether the clearance space around the burner tube
has been filled with insulation material,
- Whether the boiler door is closed properly,
- Whether the heating system has been filled up with
water and completely vented,
- Whether the thermostats are properly regulated and
whether the heating system governor has been set
according to the necessary parameters by the support
service or by the installer,
- Whether the regulation and safety devices work
properly,
- Whether all shut-off valves (of both water and burner)
have been opened,
- Whether the circulation pumps work,
- Whether the air supply is ensured and the flue outlet
is free.
The inside of the burner door is built using insulating,
refractory concrete. The residual humidity present in
the concrete, resulting from the manufacturing
process, may, during the initial operating phase,
release steam and form water droplets on the door.
The steam must be allowed to escape throughout
the pre-heating phase before reaching the operating
temperature. This process can last one week. The
increase in operating power of the burner must be
progressive during this period.
INFORMATION:
Pre-heating may result in the appearance of cracks.
Small shrinkage splits and cracks do not hinder
operation and do not represent a defect; they are
unavoidable.
The unit is put in operation by actuating the ON/OFF
switch of the control panel (position I) or possibly,
depending on the installation, by actuating a switch on
the burner or within the central control cabinet.
6.2. Decommission
The unit is put out of operation by actuating the ON/OFF
switch of the control panel (position O) or possibly,
depending on the installation, by actuating a switch on
the burner or within the central control cabinet.
Should the heat producing system remain off for several
weeks, we recommend that the following measures
be taken:
- Close the fuel supply,
- Clean and protect the heating surface of the boiler.
Your installation contractor will be pleased to give you
some advice.
- In case of frost warnings, drain the system or add an
anti-freeze product and follow the instructions given
in chapter 5.4.
