If water temperature in the hot water tank is above 48°C, diverting valve
positioned in solar connection set (Figure 5) leads water directly to mixing valve.
Thermostatic mixing valve mixes water with cold water and sends to the taps
at fixed temperature of 40°C, this phenomenon prevents people from boiling.
If water temperature in the hot water tank is below 48°C, diverting valve sends
domestic hot water to the combi boiler to be heated to demanded temperature.
Temperature of domestic hot water coming from combi boiler is also set before
being sent to the taps. Setting temperature of thermostatic valve can be set
between 25-60°C. Solar connection set is composed of a solar connection set
body and the pipes shown in Figure 5.
2.12 Use with Propane LPG
Your combi boiler can be used with propane LPG. The boiler must be adjusted
to work with propane LPG by authorized service. The boiler is suitable to work
with minimum two propane LPG tubes (depending on capacity) for only if they
are connected to the boiler via a special “collector kit”. In cold environments, the
use of thermostatic hot water buckets might be necessary to prevent fuel in the
tubes and gas line to be liquified. In case thermostatic hot water buckets are
used to heat up the propane LPG tubes; water temperature should not exceed
22°C.
