Install Instructions For US Stove 5520 Pellet Heater Glass Installation & Maintenance Kit For 891979

Instructional Notes

1.) Make sure your stove is completely shut down and cool to the touch.

2.) Open the main door.

3.) Using a screwdriver remove the screws holding the top retainer in place.

4.) Loosen the screws holding the bottom retainer in place (Normally you will not need to completely remove this retainer).

5.) Gently remove the glass by letting it tip back (Pay attention to how the gasket is placed on the glass).

6.) Install the gasket around the new glass in the same manner as the original gasket was installed on the old glass (If your new glass comes with the gasket installed skip this step).

7.) Slide the new glass into the bottom retainer on the door and gently tighten the screws.

8.) Place the screws and washers back into the top retainer.

9.) Position the top retainer back in place and tighten the screws (Do not over-tighten).

10.) Make sure to wipe any marks off the glass prior to burning the stove.

Troubleshooting Notes

-It is important to periodically inspect the glass on your unit. If you notice black or brown streaks on certain areas of the glass it may indicate that there is an air leak. Often times a leak in this area can be fixed by gently snugging the retainer screws or by replacing the gasket. If the glass is cracked or has an excessively heavy haze (Cloudy appearance) the glass should be replaced.
