Wow, what a description. You are saying canister, should be only one of two things. It is either just a canister to hold a pocket of air, so the pump doesn't run too often, or it is a water filter filter canister. If it is either one, it should be on the hose that comes from the bottom of the water heater, and not the hose that is on top. If the canister is pointing down, it is a water filter housing, and the bottom part should screw off. Never heard of a water heater flushing system, but there are other things I've never heard as well. Good Luck, and a picture would be very helpful. As for manuals, they wouldn't tell you anything anyway, very generic.
