General Vent Installation; Installation Of Side Wall Venting - Kingsman Marquis Atrium MCVP42NH Installation Instructions Manual

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. This appliance is also approved for use with 5 x 8 M&G-Duravent Direct
Vent system (Model DV-GS Series), BDM Pro Form Direct Vent, Ameri-Vent Direct Vent Pipe System, ICC Excel Direct, Metal Fab Sure-Seal DV and
Selkirk Direct Temp.
RIGID OR HARD PIPE
When using 5 x 8 M&G-Duravent, Ameri-Vent pipe, BDM Pro Form Direct Vent, ICC Excel
Direct, Metal Fab Sure-Seal DV and or Selkirk Direct Temp a 5 x 8 M&G Duravent hard pipe
adapter must be used (part # Z58DFA). Follow installation instructions provided by M&G-
Duravent/Ameri-Vent/Selkirk Direct Temp, ICC Excel Direct, and 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 M&G-Duravent venting.
NOTE: Increase framing depth by one inch when using hard pipe.
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 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 stabilize 5" flex in the center
of 8" flex. When forming bends place spring in bend or before and after. (See Fig. 1). Horizontal
runs require support metal straps every 2 feet. In offset installation support straps should be
used to stabilize pipe.
Expand 5" and 8" flex pipe to the point that the 8" protrudes approximately 2 to 3 inches past
outer wall and the 5" flex protrudes approximately 2 to 3 inches past the 8" flex. (See Fig. 1).
Attach the 5" pipe to the termination first and secure with sealant and screws then attach the 8"
flex to the termination with caulking and screws. Termination may then be moved back to the
outer wall and attached to home screwing into the framing. Silicone around termination to
waterproof. If siding shield is going to be used attach this using same attaching hole as the top
of termination after termination has been caulked for water proofing.
Use Hi Temp Sealant
Apply a bead of Mill Pac high temp sealant to all joints and use four screws to secure each
pipe at fireplace, termination and any joint if joining any sections of pipe.
⚠
WARNING: DO NOT mix parts from different systems unless stated in the manual.
1. To determine the minimum distance from the bottom of fireplace to center of
vent see the Framing Your Gas Fireplace section. Cut a hole through the
wall allowing for a 12" x 12" (inside diameter) in combustible walls for wall
thimble or a 9" diameter hole in a non-combustible wall (See Figure 2).
2. For the clearance to combustible above a 90 degree bend see Clearance to
Combustibles section.
3. Select the approximate vent length, precise measurements are not needed as
your flex pipe can be expanded to twice its shipped length for ease of
installation
To install wall thimble center over 12" x 12" (inch) framing from both sides of
4.
wall and secure. Route flex vent pipe through wall thimble (See Figure 1).
5. Before joining pipes, apply a bead of high temperature sealant (Mill Pac) to
end of pipe. First attach the five inch (5") flue pipe to the vent termination with
sealant, and secure with the four screws provided. At this time make sure the
spacer springs are attached to the (5") flex pipe as required. Then attach the
eight inch (8") pipe by the same method.
6. Mount vent termination and seal to wall using caulking around the wall thimble
to weather proof. After installing the vent termination, double check to make
sure the pipe extends properly through wall thimble and into vent termination.
7. Before joining pipes to fireplace flue, apply a bead of high temperature sealant
(Mill Pac) to end of pipe. First attach the five inch (5") flue pipe to fireplace with
sealant, and secure with the four screws provided. At this time verify that the
spacer springs are attached properly to the (5") flex pipe as required. Then
attach the eight inch (8") pipe by the same method.
8. Support horizontal pipes every two (2) feet (61 cm) with metal strap bands.
Re-check fireplace to make sure it is level and properly positioned and
secured.
Support vertical pipes to maintain a minimum of 1" or greater clearance to
9.
combustibles with metal strapping bands.
10. If finishing the outside wall with vinyl or wood siding it is recommended that a
Siding Shield be installed, Part Number ZDVSSLR.
Note: Vent Termination must not be recessed into wall or siding.
