Useful tips
Checking Heating water pressure
There is a Replenish valve and a Pressure relief valve below the boiler.

Check pressure gauge
- In case the pressure of heating pipes falls below 1kgf/cm , open the replenish valve to refill the water to
1~2kgf/cm . (In case the water supply pressure is below 1kgf/cm , fill the water to the full capacity.)
- If there is excessive pressure inside the heating pipes, the pressure relief valve automatically discharges
the water inside the boiler to maintain optimal pressure level. In this case, you pull the pressure relief valve
upward and it sends out the water until the pressure falls below 2kgf/cm .
- Low pressure of heating pipes may disturb the circulation of heating water.
(Usable minimum pressure is 0.2kgf/cm )
Pressure gauge
Pessure relief valve
- The pressure relief valve is a safety device which prevents the heating pipes from bursting or the boiler from
malfunctioning.
- When the pressure is above 2.7~3kgf/cm , the pressure relief valve expels water to reduce the pressure inside
the heating pipes and stops at the optimum level automatically.
Caution
- You are careful not to burn yourself when you open the pressure relief valve
because hot water may flow out.
- You need to use extra caution when you open the pressure relief valve because
the high pressure heating water in pipes may shoot out.
