3.3.7 Refractory Replacement
The intense heat of the fire will normally cause hairline cracks in the refractory. These cracks
can be minimized by proper curing as described in “First Fires”. They will not normally
diminish the effectiveness of the refractory. If large cracks develop, then the refractory should
be replaced. To replace the refractory bricks, follow these steps:
1. Remove the left side bricks
2. Remove the right side bricks
3. Remove the back bricks
4. Remove the two floor bricks
To install the new bricks, follow the
above steps in reverse.

3.3.8 Glass Care – Replacement
The glass used for the OSBRUN
STRATFORD
is a high temperature ceramic glass (1400º F).
If the glass breaks, it must be replaced with an identical ceramic glass. Tempered glass or
ordinary glass will now withstand the high temperatures of the OSBURN
STRATFORD
.
Replacement glass should be purchased from a Osburn dealer (see “Replacement Parts”, in
Section 7 – APPENDIX). Do not operate the unit with a cracked or broken glass.
3.3.9 Glass Care – Cleaning
The OSBURN
STRATFORD
is designed to keep the glass clean under normal operating
conditions. If the OSBURN
STRATFORD
is operated continuously with the combustion air
controls closed, the glass will tend to get dirty unless the fuel, firebox and glass are
maintained at hot. To clean the glass, there are a number of specially designed cleaners. Your
authorized Osburn dealer can recommend a suitable cleaner which is available in your area.
Regular household glass cleaners will not clean creosote. Do not use abrasives such as steel
pads, steel wool or oven cleaner as they will scratch the glass.
3.3.10 Gasket Replacement
Remove the doors from the unit and lay them on a clean, unabrasive surface. To replace the
gasket around the door frame, first remove the old gasket and adhesive. Make sure that the
surface is totally clean before applying new adhesive (a high temperature silicone caulking
