How to Bleed a Boiler Furnace
In the past, boiler heaters were an extremely popular way of heating buildings and homes. Boiler heaters can last a very long time if the heater is properly maintained. Part of maintaining a boiler heater is bleeding it from time to time. It is not a complicated procedure and can easily be done by following a few guidelines.
Supplies needed:
Container
Safety glasses
Radiator key or screwdriver
Locate the boiler heater. Put your
safety glasses on. Find the bleed valve for the boiler heater. The
bleed valve will be located close to the radiator. You can easily
find the bleed valve by feeling around the chambers and fins of the
radiator. Once you have located the bleed valve, place your
container directly below it. The container will catch the water
dripping from the valve. Use the radiator key or screwdriver to turn
the bleed valve clockwise. Do not rush this process. Turn the valve
clockwise slowly. It is not uncommon to hear a hiss when the bleed
valve has been completely rotated.Look for a valve on a pipe that is
directly above the boiler furnace. Turn the valve to release water
into the system. Monitor the boiler gauge while you are releasing
water into the system. When the gauge has a normal reading, stop
releasing water into the system. Do not stop releasing water until
the gauge has a normal reading. Do not let the reading dip below the
normal range.Turn the bleed valve back to its
original position. Remove the container from underneath the bleed
valve.
