I installed a Tiger Loop in a W/M oil fired Gold boiler today. I finally got it to purge but let me tell you it wasn't easy getting the oil 50 feet away and 9 feet high to the burner. After starting the burner numerous times to try to draw the oil to the burner I finally filled up the filter with fuel oil and filed a bucket 1/4 with oil and disconnected the feed to the TL and fed a line right into the bucket and the burner fired in about 1 minute. After that I reconnected the TL to the oil tank line and then and only then did it begin to draw oil.
