If you use a rear heat shield to obtain reduced clearances, you must use the optional rear heat shield
manufactured by Hearthstone available through your local dealer. Close clearance connector pipe must be
tested to UL standards and listed. Check listings of your pipe for actual clearances. Shown are measurements
typical only and specific to Simpson Dura Vent DVL brand. Clearances cannot be reduced without the use of the
rear heat shield and/or with close clearance connector pipe and/or by protecting the surfaces per NFPA 211
standards
