USE SUPPORTS OR EQUIVALENTNON-COMBUSTIBLE STRAPPING TO MAINTAIN THE REQUIRED CLEARANCE FROMCOMBUSTIBLES. USE WOLF STEEL LTD. SUPPORT RING ASSEMBLY W010-0067 OR EQUIVALENTNON-COMBUSTIBLE STRAPPING TO MAINTAIN THE MINIMUM CLEARANCE TO COMBUSTIBLESFOR BOTH VERTICAL AND HORIZONTAL RUNS. SPACERS ARE ATTACHED TO THE INNER PIPE ATPREDETERMINED INTERVALS TO MAINTAIN AN EVEN AIR GAP TO THE OUTER PIPE. THIS GAP ISREQUIRED FOR SAFE OPERATION. A SPACER IS REQUIRED AT THE START, MIDDLE AND END OFEACH ELBOW TO ENSURE THIS GAP IS MAINTAINED. THESE SPACERS MUST NOT BE REMOVED.
