Firebox Door
Principles of the Firebox Door
The firebox door is insulated to prevent warping of the door. It is important that
the firebox door seal maintains an airtight seal.
Operation of the Firebox Door
To visibly inspect the inside of the firebox if needed.
Refer to Safe Operating Guidelines for further instructions on how to safely open
and close the firebox door or contact your local dealer.
Maintenance / Result
A properly closed firebox door will not allow smoke to enter or escape the firebox.
Maintain a tight seal
all around the perimeter of the firebox door at all times. There may be times when the perimeter of the firebox
door will build up with “creosote strings,” especially along the bottom if the firebox door is not closed properly.
The seal itself consists of a rope in the groove of the firebox door, covered with high temperature silicone.
Failure to manage and maintain the firebox door could result in premature replacement of parts and a buildup
of creosote.
Removal and Replacement
To remove and replace the firebox door, follow these steps:
1) Turn off power to the combustion air blowers.
2) Ensure that the fire in the firebox is extinguished.
3) Lift the firebox door off by lifting straight up.
4) Replace the firebox door with a new one.
Note: Ensure there is a tight seal around the firebox door frame while it is closed and latched shut. The
firebox door must remain parallel with the door frame.
