Weil-Mclain Gas boiler insertion repair kit
What has been done to prevent the screws in this kit from breaking again due to the intense heat from boiler? I own WM Ultra Gas Boiler. In November 2014 the bolts on cone broke off a second time when attempting to remove cone to service boiler. Now the burner is un-serviceable again. The bolts first broke when service was attempted February 1, 2014. The heat ex changer access cover was replaced at my expense on February 17, 2014.
