2 Product information
To ensure safe, economical and environmentally friendly use of the
heating system, we recommend that you carefully read the safety
instructions and operating instructions.
These instructions provide the operator of the heating system with an
overview of the use and operation of the boiler.
2.1 Correct use
The boiler is designed for heating central heating system water and
indirect provision of domestic hot water (e.g. via a hot water storage
tank) in residential buildings or apartment buildings. Any other purpose
is considered improper use.
2.2 Certification and testing mark
This appliance has been tested and meets the basic standards for the US
and Canadian markets.
2.3 Disposal
▶ Dispose of boiler packaging in an environmentally-responsible
manner.
▶ All heating system components that have to be replaced should be
disposed of in environmentally-responsible manner at an authorized
disposal site.
2.4 Product description
The G234X model boiler is a low temperature atmospheric gas-fired
boiler.
The boiler consists of:
• Ignition module and boiler temperature controller
• Boiler jacket and front door
• Boiler block with insulation
•Gas burner
The ignition module and boiler temperature controller monitor and
control all electrical components of the boiler.
The boiler jacket prevents energy loss and acts as soundproofing.
The boiler block transfers the heat generated by the burner to the boiler
water. The insulation prevents energy loss.

3 Operation
3.1 Before operating the appliance
Before starting up the appliance, make sure that
• the operating pressure is sufficient
• the fuel supply has been turned on at the main shut-off valve, and
• the heating system emergency shutoff switch is in the ON position.
3.2 Checking the operating pressure, topping up
the boiler water, and purging air from the system
The water used for filling the heating system loses a substantial amount
of volume in the first few days due to the release of its gas content. This
causes air pockets to form and the heating water starts to make noises.
▶ With new heating systems, check the operating pressure daily at first,
topping off the heating water and bleeding the radiators if needed.
▶ Later on, check the operating pressure monthly, topping off heating
water and purging the boiler and radiators if needed.
3.2.1 Checking the operating pressure
Your heating contractor will have set the system to the required
operating pressure of at least 15 psi (1 bar) and entered the setting in
Tab. 2, page 5.
▶ Read the current operating pressure and temperature from the
temperature/pressure gauge.
▶ If the temperature/pressure gauge needle drops below the minimum
pressure marker of 15 psi (1 bar), the operating pressure is too low.
Add water to the system.
The boiler is fully functional with the factory-installed
