Installation of Sidewall Venting
Note that the minimum height from the bottom of fireplace to the centre of vent is 55-1/2" [141 cm] for the MQZDV3927 and
68-1/2” [174cm] for the MQZDV4634. This dimension is for installations where venting exits immediately after its rise from the
unit (i.e. zero/minimum horizontal length). In installations where there is a horizontal run simply refer to the Horizontal Vent
Table to determine the vertical location of the hole cutout required.
1. In a combustible wall cut a square hole that is 11” x 11” [28cmx28cm] (inside dimension) for the MQZDV3927 or 13-3/4" x
13-3/4" [35cmx35cm] for the MQZDV4634. In a non-combustible wall, cut an 8” [20cm] diameter hole for the MQZDV3927
or an 11" [28cm] diameter hole for the MQZDV4634. Refer to Figure 26 for detail.
2. Note the clearances to combustible as stated on pages 13. Select the approximate vent length for your installation. Note
that precise measurements are not needed as the flex pipe can be expanded to twice its shipped length.
3. If installing the wall thimble, center it over the square cutout hole and secure both pieces on either sides of the wall. Route
the flex vent pipe through the wall thimble. Before joining pipes, apply a bead of high temperature sealant (Millpac) to the
end. Then attach the inner pipe to the vent termination with sealant, and secure it with the four screws provided. At this
time make sure the spacer springs are attached to the inner flex pipe. Then attach the outer pipe by the same method.
4. Mount the vent termination and seal it to wall using caulking around the thimble to weather proof. After installing the vent
termination, double check to make sure the pipe extends properly through wall thimble and into the termination. Before
joining pipes to the fireplace flue, apply a bead of high temperature sealant (Millpac) to the end of it. Then attach the inner
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 inner pipe and then attach the outer pipe by the same method.
5. Support the horizontal pipe every 2ft [61cm] with metal strap bands. Verify that the fireplace is leveled, properly
positioned, and secured to the framing.
6. Support vertical pipes with metal strapping to maintain a minimum of 1" [2.5cm] or greater clearance to combustibles.

Note: Vent Termination must not be recessed into wall or siding. If finishing the outside wall with vinyl or wood siding it is
recommended that a Siding Shield be installed. Use the proper vent termination shield for the type of termination style.
