Converting a Masonry Chimney

Important: The existing masonry flue opening needs to have an area of at least a 36 sq. in. to insure proper intake/ex- haust flow.

to fit chimney. Diagram 7.

1)Before cutting any holes, assemble the desired sections of black direct vent pipe to determine the center of the masonry pene- tration.

2) Once the center point of the penetration has

been determined, cut a 6" (152mm) dia. hole

in the masonry. Be careful, if the hole is too

large, the Retro Connector might not mount

properly, and if the hole is too small, then the

appliance might starve for intake air. If there

is a frame wall in front of the masonry wall,

cut and frame a 10" (254mm) clear square

opening in the wall (centered around the 6"

(152mm) masonry opening). If there is sheet

rock only (no studs) in front of the masonry,

the 10" (254mm) clear opening is still need-

ed, but does not need to be framed. This

allows the Retro Connector to mount direct-

4)To determine the length of flex required, measure from 3" (76mm) above the top of the Flashing down to the level of the open- ing. Add to this measurement the distance from the center of the chimney to out through the wall. Cut a piece of 4" flex to this length (the flex should already be extended to its nominal length).

5)Connect the 4" flex liner to the Top Adaptor (Part # 985K) using 3 sheet metal screws. Diagram 2.

6)Feed the 4" flex liner through the Flashing into the chimney. Continue to feed the liner out through the opening in the masonry wall.

7)Secure the Top Adaptor to the Flashing. Use 3 sheet metal screws through the side of the adaptor into the flange on the Flashing (diagram 8). Twist lock the Termination Cap (Part # 980 or 991) on to the Top Adaptor.

9)Slide the Wall Thimble Cover (Part # 940) over the Retro Connector and secure with masonry bolts. Diagram 10. If you have a framed wall in front of the masonry, use wood screws to mount the Wall Thimble Cover to the framed wall, over the Retro Connector and the 10" (254mm) square framed opening. Diagram 11. 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.
