 U39 ULTIMATE Direct Vent Freestanding Gas Stove

1)  Before cutting any holes, assemble the 

desired sections of black direct vent pipe 
to determine the center of the masonry 
penetration.

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 needed, but does not need to be 
framed. This allows the Retro Connector to 
mount directly on the masonry and provide 
clearance to the combustibles. Diagram 
11.

3)  Secure the Flashing (Part # 705C) to the 

top of the masonry chimney using a bead 
of non-hardening sealant-adhesive. If the 
Flashing is larger than the top of the chimney, 
then cut and fold fl ashing as needed to fi t 
chimney. Diagram 7.

4)  To determine the length of fl ex required, 

measure from 3" (76mm) above the top of 
the Flashing down to the level of the opening. 
Add to this measurement the distance from 
the center of the chimney to out through 
the wall. Cut a piece of 4" fl ex to this length 
(the fl ex should already be extended to its 
nominal length).

5)  Connect the 4" fl ex liner to the Top Adaptor 

(Part # 985K) using 3 sheet metal screws. 
Diagram 2.

6)  Feed the 4" fl ex 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 fl ange on the Flashing 
(diagram 8). Twist lock the Termination Cap 
(Part # 980 or 991) on to the Top Adaptor.

8)  Attach the fl ex to the Retro Connector. Use 

3 sheet metal screws to attach the fl ex 
liner to the Connector. Diagram 9. Mount 
the Retro Connector to the masonry wall 
using masonry bolts. Re-drill larger holes 
on connector as needed. Be careful to 
insure that the connector is centered in the 
opening and the mounting holes line up with 
the masonry wall.

4)  Pass the fl ex pipe down through the center of 

the chimney system, and center the adaptor 
on the top of the chimney pipe. Drill four 1/8" 
diameter holes through the adaptor and into 
the chimney top. Insure that   you are in 
fact, drilling into the metal on  the chimney. 
Twist-lock the Termination Cap (Part# 980 
or 991) onto the Adaptor. (Diagram 3 and 
4).

5)  Pull the fl ex pipe down through the ceiling 

support box, until it protrudes approximately 
3" (76mm). Connect the fl ex pipe to the Retro 
Connector by slipping it into the 

 

4-3/4" diameter sleeve on the top side of 
the Connector. Use 3 sheet metal screws 
to assemble these two parts.

6)  Push the fl ex pipe back up into the ceiling 

support box, center the Retro Connector, and 
attach it to the support box, or decorative 
sleeve for double wall solid packed pipe, 
with the sheet metal screws (supplied). 

 

The holes in the Retro Connector are pre-
punched. Diagram 5.

7)  The connection between the appliance and 

the Retro Connector may be completed with 
sections of black direct vent pipe, together 
with an adjustable length.
