I have a gas hot water cast iron system,
when the heat goes on I hear a knocking
sound in the pipes for a min or two and
then it stops. The knocking only happens
on startup. Thanks for you help.

Vents

Do you have air vents in the water lines? Look for these, open slowly with wrench and let any air escape until water begins to come out. Then close tightly. This should be done once a year.
