Step 9.
Attach the flex to the retro connector. Use three sheet
metal screws to attach the flex liner to the connector
(Fig. 26). Mount the retro connector to the masonry
wall using masonry bolts. Re-drill larger holes on
connector as needed. Be careful to ensure that the
connector is centered in the opening and the mounting
holes line up with the masonry wall.
Step 10.
Slide wall thimble cover (SDV #940) over retro
connector and secure with masonry bolts (Fig. 27). If
you have a framed wall in front of the masonry, use
wood screws to mount wall thimble cover to framed
wall, over retro connector and 10” (25.4cm) square
framed opening (Fig. 22, Page 30). If needed, add a
section of direct vent pipe to the retro connector in
order to extend through the opening in the wall thimble
cover.
Step 11.
The connection between the appliance and the retro
connector may be completed with sections of direct
vent pipe.
WARNING: If any other appliances have been
previously attached to this masonry flue or an open
fireplace, etc., all openings into flue should be sealed
properly. It is very important that there is only one
appliance on a vent system and that there are no air
leaks into the masonry chimney itself other than the
vent appliance venting.
WARNING: Failure to position the parts in accordance
with these diagrams or failure to use only parts
specifically approved with this appliance may result
in property damage or personal injury.
