Marquis Cove MQZDV3927N Installation Instructions Manual page 11

For horizontal venting, with a 90° bend directly from the unit, please note the following: At the top of the 90° bend there must
be a clearance of at least 4" [10.1cm] for the MQZDV3927 and 11" [27.9cm] for the MQZDV4634 between the pipe and any
combustible material. This is illustrated in Figure 4. For the rest of the length, along the top of the horizontal pipe, a minimum
clearance of 2-1/2" [6.4cm] for the MQZDV3927 and 3-1/2" [8.9cm] for the MQZDV4634 is required. Please refer to the
Venting section of this manual for a detailed guide in vent configurations.
This unit allows for flooring or hearth material to extend 1-3/4" [4.4cm] above the bottom of the fireplace. Refer to the facing
material section for dimensions and details. Make note of the non-combustible material areas.
The minimum ceiling height for this unit is 5ft [1.52m] for the MQZDV3927 and 6ft [1.83m] for the MQZDV4634. Please note
that it is possible to raise the appliance above the floor. However, it is crucial to maintain the minimum ceiling height. For
example: If the height from the floor to the ceiling of the living space is 10ft [3.05m] then the appliance can only be raised a
maximum of 5ft [1.52m] for the MQZDV3927 and 4ft [1.22m] for the MQZDV4634.
