6.0 Cleaning and Maintenance
The following precautions must be taken prior to start any cleaning or maintenance activity:
-
Make sure there are no embers in the top or bottom chamber and ashes have cooled down
completely. Also make sure that all panels of the burner are at room temperature.
6.1 Periodic Cleaning & Checks
Depending upon the usage certain parts or areas of the Cromwell burner will need cleaning every week or
fortnight.
6.1.1 Ash Removal
The downdraft burner creates considerably less ash compared to conventional wood burners. Depending upon
usage, ash removal will be required every week or as required.
-
Open the top combustion chamber door and & remove the top downdraft injector by lifting vertically.
-
Using a small brush, push accumulated ash into bottom chamber through injector hole.
-
Open the bottom chamber door
-
Insert a metal pan into the lower combustion chamber and using a small brush swap ash on to pan.
-
Remove the metal pan with ash and empty it.
-
Carefully put back the downdraft top injector back in place.
-
Do not remove to the ceramic block during this regular ash removal process. Only make sure that it is in
place.
-
Ensure that the ceramic block is pushed at the rear and held in place. Then close the bottom chamber door.
6.1.2 Cleaning the Glass
It will be necessary to clean the glass after long usage or when improper fuel is burnt. A dampened paper towel
newspaper with cool ash or a non-caustic oven cleaner can be used to clean the glass. Do not scrub using steel
products or abrasive material, as it can leave scratch marks on the glass and damage printing on the glass.
6.1.3 Cleaning the Panels
A soft dry cloth is sufficient to clean and maintain the finish of the panels. Household detergent or a damp cloth
must not be used as they may damage painted panels or give bad odors while running the fire.
6.1.4 Visual checks
-
Make sure that the top downdraft injector is sitting properly with correct orientation in the top combustion
chamber. (Refer 5.2C)
-
All boards in both the combustion chambers are in place and are in good condition.
-
Make sure that the ceramic block in the bottom chamber is sitting properly in the bottom combustion
chamber. If the holes of this ceramic block appear to be filled with fly ash, remove it from the bottom chamber
and dust off using a soft brush.
