26 Installing the System Piping
4.4 Installing the Support (Optional)
Place the support on a flat floor, and then place the boiler on
the support securely so that the boiler does not move during
operation.

Note
If the support is not level with the floor, adjust the
height of the stoppers on the support to make it level
with the floor.
4.5 Filling the System
The LCB700 boiler is equipped with an automatic air vent. This
automatic air vent eliminates air in heating systems without the
need for manual intervention. This prevents undesired noise,
wear of devices in the circuits and inefficient performance of
heating units.
Unloosable
dust cap
Note
The dust cap is separated and shipped in the
accessory. If the air vent is out of order or leaking due
to a malfunction, close the air vents using the dust
cap included in the accessory.
To connect the condensate drain:
1. Connect an integrated drain hose to the 21.5 mm at the
bottom of the boiler.
Use only corrosion-resistant material for the integrated drain
hose, such as PVC or CPVC. Do not reduce the size of the
integrated drain hose to less than 21.5 mm. The integrated
drain hose can be connected to the condensate trap using a
condensate trap hose. The hose connection must be secured
with a drain hose clip.

2. Place the free end of the integrated drain hose into an
appropriate drain.
3. If you are using a condensate pump, ensure that the pump
allows for up to 3 LPH of drainage for each boiler in the
system.
4. If you are not using a condensate pump, ensure that the
integrated drain hose is pitched downward at a minimum
slope of 6 mm per 30 cm.
Note
Water must be poured into the exhaust connection to
fill the condensate trap.
