Why do radiators need exhaust? Because the radiator will have gas entering the heating pipe during the heating process, when the gas is congested, the heating will not be hot, so a vent valve should be installed above the radiator to release the gas and make the heating system circulate smoothly.

First, check whether the pipe inlet valve is in the open state, if it is open, then close it.

Secondly, there is a bar above the air release valve, and there will be a small hole on the side. Then use the air exhaust key to twist it so that the small holes are aligned with the air release port and start air release. After the water is discharged, the air release can be closed Valve out.

After the SNDA steel plate radiator goes through the above exhausting steps, when the next winter comes, it can better provide warmth to the family.
