10.2 Mounting procedure
1. Put the boiler on the required standpoint (it is necessary to respect the demands on boiler positioning stated in chapter 9.2)
according to the project documentation . We recommend transporting the boiler to the determined standpoint on a pallet, preferably
still wrapped in protective packing. If this is not possible due to the lack of space, convey the boiler without the packing holding it by its
base plate.
In no case is allowed to lift the boiler by the heating water pipe or the gas pipe. The boiler has to stay firmly on a non-
flammable pad in the vertical position and has to be sufficiently balanced.
2. Mount the TE branch, to the heating water output, mount the discharge valve to the heating water input, mount the automatic air-
relief valve to the heating water output (fig. No. 23). The parts are delivered with the boiler.
3. Connection to the heating system is to be performed according to the project documentation.
4. Assemble the horizontal draught diverter, mount the sensor of the flue gases reverse flow safety device. The parts are delivered
with the boiler.
5. It is forbidden to exclude from operation the flue gases reverse flow safety device. It is forbidden to intervene unprofessionally
into the flue gases reverse flow safety device. To mount the flue gases reverse flow safety device and replace their defect parts,
only original parts delivered by the manufacturer must be used.
6. Perform connection to the chimney.
7. Perform installation of the water heater (if required). To ensure preferential hot water heating, we recommend using the Honeywell V
4044F three-way valve. Mount a backflow valve between the pump and the three-way valve. During mounting, it is necessary to observe
the direction of connection according to the designation on this valve.
Fig. No.21 shows the valve in a position when the heating water supply to the heating system is opened. In case of requirements for
domestic hot water, the output "B" into the heating system is automatically closed and the output "A" into the reservoir is opened.
The valve has to be mounted in the position shown in fig. No. 25 and 26.
During mounting, no rotation of the valve is allowed!
8. Connecting the boiler to the gas connection.
Connecting gas to the boiler by means of a spherical shut-off valve.
9. Release the air-relief screw of the automatic air-relief valve. It must be released at water filling into the heating system, as well as
during boiler operation.
