Wolf MGK-130 Technical Manual And Installation Instructions page 16

Condensate lifting system (accessory)
The Wolf condensate lifting system is fully wired and
can be integrated into the MGK. The power supply and
the alarm output of the condensate lifting system are
connected to the boiler control unit.
6 m PVC hose for draining off the condensate is
included.
Connection of a Wolf cylinder,
solar cylinder SEM or third party cylinder
We recommend the MM or KM controllers from the range of Wolf accessories for optimum switching of heating circuit
and cylinder primary pumps.
When sizing the cylinder ensure that the lowest constant cylinder output corresponds at least to the lowest
heat input from the boiler. A solar cylinder (without solar thermal system) can be connected to increase the
constant DHW output. For this, both internal indirect coils need to receive a volume flow in series. Otherwise
it cannot be assured that the cylinder will be fully heated up.
Gas connection
Routing the gas pipe as well as making the gas connections must only be carried out by a licensed gas
fitter.
Remove all residues from the heating pipework and the gas line prior to connecting the condensing boiler,
particularly in older systems.
Prior to commissioning, test all pipe and gas connections for leaks.
Inappropriate installation or using unsuitable components or assemblies may lead to gas escaping, which
results in a risk of poisoning and explosion.
Install a gas ball valve with fire protection in the gas supply line upstream of the Wolf condensing
boiler. Otherwise explosions may occur during a fire. Size the gas supply line in accordance with local
regulations.
Check the gas line for tightness without the boiler.
Never release the test pressure via the gas valve.
Gas fittings on the appliance may be pressure tested to 150 mbar. Higher pressure may damage the
gas train, resulting in a risk of explosion, asphyxiation or poisoning.
Close the gas ball valve on the gas condensing boiler to pressure test the gas line.
Mount the gas ball valve in an easily accessible place.
• Prior to installation, ensure that the boiler is set to the available gas type.
At the factory, the boiler is set up for natural gas H 15.0:
Ws = 11.4 - 15.2 kWh/m
When changing the gas type, set the appliance in accordance with chapter "Changing the gas type/CO
• Only commission the appliance when the rated supply pressure has been reached.
