Default how to drain and refill heating system?


"comcastss news groups" wrote in message
et...
I have an oil fired burner with forced hot water, two zones, I want to
drain
one zone to modify a radiator (shorten it) and then refill the system.
Would this be difficult? should I get the furnace company out to do it.
I would prefer to do it myself as it will be difficult to coordinate if I
have to get the oil company out to do the service...


I'm hoping this procedure is simple and I can do it myself.


Can you open and close valves? Turn the boiler switch off. Close the feed
to the system. Find the drain valve, usually on the return line of the loop
and drain the water. Do your work, close the drain, open the fill. Once it
stops running, you'll have to turn the heater on, run the system and crack
open the drain valve to vent some of the air.
