Door and Glass Information

Glass Cleaning

It will be necessary to clean the glass periodically. During startup, condensation, which is normal, forms on the inside of the glass,
and causes dust, lint etc. 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 circumstances.
Cautions and Warnings
• Do not clean when the glass is hot.
• The use of substitute glass will void all product warranties (see Glass Replacement in this section).
• Care must be taken to avoid breakage of the glass.
• Do not operate this fireplace without the glass front or with a broken glass front.
• Do not strike or abuse the glass.

Glass Replacement

Only Robax ceramic or coated Neoceram glass may be used for replacement for Models MQRB5143 and MQRB6169. Glass must
be minimum 5mm thick.
To replace glass, clean all materials from the door frame. Scrape off old silicone all the way down to the metal. Using high-temp
silicone [rated up to 500°F (260°C)] apply a continuous bead of approximately 1/8"-3/16" to all four [4] sides of the frame. With the
frame resting on a flat surface, insert the new glass with a new gasket. Gently press the glass into the silicone. Be careful not to use
excessive force on the glass. Let the silicone dry for approximately 15-20minutes.
Use caution when removing broken glass. Wear gloves.

Removal of the Glass Door

1.
Remove the door by unlatching the 2 top latches. Simply place 2 fingers in the grooves, and pull and lift upward slightly.
2.
Once the top of the door is unlatched, tilt the door forward and lift upward to release the bottom.
3.
When re-installing the door, place the bottom of the door into the door retainer slot and then secure the door with the top latches.

Spring Replacement

*Over time, the door latch spring (Part#36HB-123) may need to be replaced if tension is lost.
1.
To replace latch spring, remove the 2 hex screws (located in the firebox) that secure the latch assembly in place.
2.
Once the screws are removed the latches will slide out of place.
3.
Remove the locknut from the latch assembly and replace the spring. Re-tighten the locknut until 2 thread turns are beyond the
locknut. This is critical for proper tension. Replace latch assembly.
