General Vent Installation Information
This gas appliance is approved to be vented either through the side wall or vertically through the roof. Only Kingsman Flex (Z-
Flex) Venting Kits and components specifically approved and LABELED for this stove may be used. MQZDV3927 is also
approved for use with Simpson Dura-Vent Direct Vent system (Model DV-GS 5/8 for MQZDV3927 only), AmeriVent Direct
Vent Pipe System, ICC Excel Direct, Metal Fab Sure-Seal DV and Selkirk Direct Temp.
Rigid or Hard Pipe for MQZDV3927
When using Simpson Dura-vent, AmeriVent pipe, ICC Excel Direct, Metal Fab Sure-Seal DV and or Selkirk Direct Temp a
Dura-vent hard pipe adapter must be used (part no. Z57DFA for MQZDV3927). Follow installation instructions provided by
Simpson Dura-vent/AmeriVent/Selkirk Direct Temp, ICC Excel Direct, Metal Fab Sure-Seal DV for installation of pipe and
adhere to the clearance to combustibles provided in this manual. Apply a bead of Mill Pac high temp sealant to all joints of
pipes, adapters and termination, when using Kingsman Flex (Z-Flex) venting and Simpson Dura-vent venting.
Flex Pipe Venting
Kingsman Flex pipe is shipped in unexpanded length. When installing pipe expand the lengths. Pipe can be expanded to twice
their lengths (e.g. 4ft to 8ft). Fully expand pipe and cut off excess.
Do not use more than two [2] couplers to extend short pipes. Single sections are preferred in an installation attaching at the
fireplace and termination.
Place the spring spaces provided approximately every two feet to position the inner pipe centered in the outer pipe. When
forming bends place spring in bend or before and after. Horizontal runs require support metal straps every 2ft [0.61m]. In offset
installation support straps should be used to stabilize pipe.
Expand the coaxial flex pipe system to the point that the outer pipe protrudes approximately 2 to 3 inches [5.1cm-7.6cm] past
outer wall. Additionally, the inner flex should protrude approximately 2 to 3 inches [5.1cm-7.6cm] past the outer pipe. Attach
the inner pipe to the termination first and then secure it with sealant and screws. Then attach the outer flex pipe to the
termination also with caulking and screws. The termination may then be moved back to the outer wall and attached to the
home by screwing into the framing. Apply silicone to around the termination to waterproof the installation. If a siding shield is
going to be used attach it using the same attachment holes as the top of the termination AFTER the termination has been
caulked and sealed.
Use Hi Temp Sealant
Apply a bead of Millpac high temperature sealant to all joints and use four screws to secure each pipe at the fireplace,
termination and any joints when joining sections of vent pipes.
