Glass Door And Latch Removal Guide - Marquis Cove MQZDV3927N Installation Instructions Manual

The latches to secure the glass door are located on the sides of the unit. In the MQZDV3927 model there are four [4] latches
in total holding the door in place, while the MQZDV4634 has six [6]. Over time the spring tension on the latches will weaken. If
this is the case simply remove the latch assembly by unfastening the hex screws, unbolt the Lock Nut, and replace the
springs. Care should be taken when handling the springs. NOTE: The tension on the springs is specifically set at the
factory and must never be changed. Changing the tension can cause damage to the appliance, damage to property,
and/or personal injury. When reinstalling the lock nut for spring replacement, tighten it so that two [2] threads are
showing past the nut.
To remove the glass door simply:
1. Unlatch the door with your fingers by pulling the latches forward and away from the firebox to clear the Latch Tabs.
2. Carefully remove the glass door from the appliance.
3. Reinstalling is just the reverse of these steps.
CAUTIONS AND WARNINGS
1. Do not clean when the glass is hot.
2. The use of substitute glass will void all
product warranties.
3. Care must be taken to avoid breakage
of the glass.
4. Do not operate this fireplace without the
glass front or with a broken glass front.
5. Do not strike or abuse the glass.
6. Use caution when removing broken
glass. Wear gloves.
Glass Cleaning
It will be necessary to clean the glass periodically. During start-up condensation (which is normal) forms on the inside of the
glass, and causes dust and lint to cling to the glass surface. Also, initial paint curing can deposit a slight film on the glass. It is
therefore recommended that initially the glass be cleaned two or three times with non-abrasive common household glass
cleansers and warm water. After that, the glass should be cleaned two or three times a season depending on the usage.
Glass Replacement
The MQZDV3927 uses ceramic glass while the MQZDV4634 model uses low-e tempered. The thickness for either glass must
be 5mm. To replace the glass:
1. Clean all materials from the door frame. Scrape off old silicone down to the metal.
2. Using a high heat silicone temperature-resistant to 500°F [260°C] apply a continuous bead of approximately 1/4" [7mm] to
all four sides of frame.
3. Insert the glass with new gasket into the door frame. The frame should be on a flat surface with a small amount of weight
used to press the glass into the silicone. Let the whole glass door assembly dry for approximately 15 to 20 minutes.
4. Reinstall the glass door back onto the appliance.
