Start-up procedure
9.1
Check for gas leaks
Prior to the initial start-up check that the gas flow pipe work is gas-tight;
this must be confirmed in the start-up report.
WARNING:
▶ The boiler and its manual gas shutoff valve must be
isolated from the gas supply piping system during
any pressure testing of that system, exceeding
0.5 psi (34.5 mbar). The maximum test pressure
allowed at the manual gas shutoff valve inlet is 0.5
psi (34.5 mbar).
▶ Cover endangered positions before leak testing.
▶ Do not spray the leak testing agent onto cables, plugs
or electrical connection lines. Do not allow it to drip
onto them either.
DANGER:
Leaks may be caused to pipes and screw connections
during commissioning and maintenance activities.
▶ Carry out a proper leak test.
▶ Only use approved leak detection agents for leak
detection.
▶ If 0.5 psi (34.45 mbar) or less, slowly open the gas valve by pushing
on the gas valve and turning it ¼ rotation in a counter-clockwise
direction ( fig. 52). The gas valve is open when it is in the vertical
position.
▶ Shut off the appliance from the power supply.
▶ Check the new conduit section up to and including its connection (i.e.
direct sealing location) to the gas fitting for leaks, using a foaming
product.The maximum test pressure allowed at the manual gas
shutoff valve inlet is 0.5 mbar (0.2" W.C.).

Fill the heating system
To ensure a trouble-free operation of the boiler, read the accompanying
instructions about water quality, before filling the heating system.
▶ Push and open the control panel cover.
▶ Turn the Space heating water temperature knob [8] and DHW
temperature knob [10] counterclockwise to the "0" position.

▶ Turn the vent key a quarter rotation to undo the boiler door lock
( fig. 54, detailed picture).Push the fastener down ( fig. 54,
step 2) and open the boiler door.
▶ Remove the insulation cover of the pump group ( fig. 54, step 4).

To purge the boiler, every radiator in the heating system must have a
purge facility. In some situations it may even be necessary to provide
extra purging facilities at certain locations. The boiler itself has an
automatic air vent.
Logamax plus GB162-L.B. 80 kW / 100 kW – 6720645916 (2014/10)
NOTICE
▶ At initial start up, the boiler will start as soon as the
system pressure exceeds 15 psi (1.0 bar).
▶ If the system pressure falls below 3 psi (0.2 bar) the
boiler will stop and generate a fault code.
