Hearthstone Wood Stove Glass (Clydesdale 8490/8491).  It is important to periodically inspect the glass and glass gasket on your wood stove to ensure you have a proper seal.  A crack in the glass or a missing / deteriorated gasket could allow smoke or flue gases to enter the room.

Instructional Notes

*The replacement ceramic glass may have a coating on one side. If so, make sure that this side is placed on the exterior, away from the firebox. *

INSTALL INSTRUCTIONS:

1) To replace the glass, you will need to remove the door from the insert. Remove the door by opening it to about a 45-degree angle. While supporting the door, remove the bottom hinge pin and lift the door straight up until the top hinge pin clears the door hinge.

2) Place the door face down on a flat surface protected with cardboard or an appliance blanket.

3) Apply penetrating oil (PB Blaster) to the screws holding the glass prior to removal. Remove the screws and lift off the retaining frame.

4) Wearing work gloves, carefully remove the old glass from the door.

5) Take the new gasket and peel back the paper backing on the tape (a little at a time) and wrap it around the edge of the glass. The tape will overlap both the front and back sides of the glass. Trim if there is excess.

6) Place the new glass back into the door and replace the frame.

7) Put the door back onto the firebox and re-install the hinge pins.

Troubleshooting Notes

Helpful Tips:

If you need to remove the glass or glass gasket it is a good idea to spray any fasteners with a product like WD40 or PB Blaster prior to this step. This will greatly reduce the possibility of stripping or breaking any screws/bolts during removal. When reinstalling the glass tighten the fasteners in a crisscross pattern. This will help to ensure there is even pressure on the glass (Do not overtighten). 

Please open and inspect your glass to make sure that it has arrived intact. Damage Claims for broken glass from shipping MUST be made within 72 hrs of delivery, no exceptions. Glass breaking from after installation is NOT covered under warranty, this is due to improper installation. If you do not feel comfortable replacing your glass, please contact a licensed technician.
