(152mm) diameter hole in the masonry. If the holeis too large, the retro connector might not mount properly; ifthe hole is too small, the appliance might starve for intakeair. If there is a frame wall in front of the masonry wall, cutand frame a 10 in. (254mm) square opening in the wall(centered around the 6 in. (152mm) masonry opening). Ifthere is sheet rock only (no studs) in front of the masonry the10 in. (254mm) opening is still needed, but does not needto be framed. If the hole is framed a wall thimble is required.This allows the retro connector to mount directly on themasonry and provide the correct clearances to combustibles(Figure 5.26).Step 3.Secure the flashing to the top of the masonry chimney usinga bead of non-hardening sealant-adhesive. If the flashing islarger than the top of the chimney, cut and fold flashing asneeded to fit chimney (Figure 5.27).Step 4.To determine the length of flex needed, measure from 3 in.(76mm) above the top of the flashing down to the level of theopening. Add the distance from the center of the chimneyout through the wall. Cut a piece of 4 in. (102mm) flex to thislength (extended to its nominal length). Be sure to leave 2-3in. (51-76mm) of flex above the existing chimney to allow forconnection to the termination kit.Step 5.Connect the flex liner to the top adapter using three sheetmetal screws (Figure 5.22, page 19).Step 6.Feed the flex liner through the flashing into the chimney.Carefully feed the flex liner down the chimney to the bottomand out the opening in the masonry wall, forming an angle toline up the flex liner with the vent opening on the appliance.CAUTIONEnsure that existing chimney is functionally sound and clean.• Have inspection done by qualified chimney sweep orprofessional installer BEFORE converting to direct ventappliance.
