General information
Intended purpose:
The UltraGas AM condens boiler is
only to be operated with the fuels
detailed in the technical information/
installation instructions. The heat
produced must be carried away only
by means of the heating water. All
orifices and openings on the boiler
must be closed during operation!
Precautionary instructions:
Corrosion protection
Do not use any sprays, solvents, chlorine-containing
cleaning agents, paints, adhesives etc. in the vicinity
of the appliance. These substances can lead to
corrosion in the boiler and the flue gas system.
Filling the heating system
Mains water can normally be used for filling the
heating system. In exceptional cases, where the water
quality renders it unsuitable for filling the heating
system (highly corrosive water or water with a high
lime content), contact your approved specialist.
Checking the water level
Check the system water level at regular intervals
(page 8).
General
Hoval UltraGas AM condens gas boilers are equipped
with automatic control and safety devices. They are
normally in operation from the beginning to the end of
the heating period. During this time the necessary
boiler temperature is set by means of the automatic
heating controller.
If the boiler is also used for water heating it remains
switched on for the whole year.
Fuel
The boiler is only to be operated
with the type of gas stated on the
rating plate. Settings are made by
the installer.
Checking prior to commissioning
A new system may only be placed in operation when
clearance to do so has been given by the heating
installer.
Filling the heating system
The heating system is filled with mains water according
to the specifications of the installer. All air must be bled
from the system. Check the pressure at the pressure
gauge or hydrometer.
Filling the separate calorifier
The calorifier is to be filled on the service water-side
according to the specifications of the installer. The
boiler can also be operated when the calorifier is not
filled with water.
Safety valves
The heating system and the hot water system are
each to be fitted with a safety valve against
impermissible over-pressures.
Filling pump (boiler with separate calorifier)
The speed and flow regulation must be appropriate to
the requirements of the calorifier. Settings are made
by the heating specialist.
Heating pumps
The speed and flow regulation must be appropriate to
the requirements of the system. Settings are made by
the heating specialist.
Electrical connection
The electrical connection is to be made by a qualified
electrician. The electrical circuit diagram is located
inside the control cover.
