I have a Burnham furnace with an extrol expansion tank, have lived here 23 yrs., so furnace is older than that, usual press. is 15 this season it goes to 35 heated, does exp. tank need air? I have no instruction, have never had anything done to it, my heat/AC man doesn't seem to know about hot water systems, am scheduled to have it replaced in about a month with forced air unit.
