9.0 MAINTENANCE REQUIREMENTS

9.1 Ash Disposal

Ashes should be placed in a metal container with a tight-fitting lid.
The closed container of ashes should be placed on a non-combustible
floor or on the ground, well away from all combustible materials,
pending final disposal.
If the ashes are disposed of by burial in the soil or otherwise locally
dispersed, they must be retained in the closed container until all
cinders have thoroughly cooled.
9.2 Creosote - Formation and
Need for Removal
When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote.
The creosote vapors condense in the relatively cool chimney flue of
a slow-burning fire. As a result, creosote residue accumulates on the
flue lining. When ignited, this creosote makes an extremely hot fire.
The chimney should be inspected monthly during the heating season
to determine if a creosote buildup has occurred. If a significant layer
of creosote has accumulated (1/8" [3mm] or more) it should be
removed to reduce the risk of a chimney fire.
Inspection can be accomplished from the top of chimney cap or from
inside the stove by removing upper firebrick.
We recommend a professional chimney cleaner inspect and clean the
chimney at least once annually.

9.3 Glass Information

Do not operate this appliance with the glass frame assembly removed,
cracked, or broken. The glass assembly shall only be replaced as
supplied by Hussong Mfg. Co., Inc. Replacement of the glass assembly
must only be performed by a licensed or qualified service person. DO
NOT SUBSTITUTE MATERIALS.
• Do not strike or slam doors. This may cause glass damage.
• In the event of glass breakage, let fireplace cool completely.

• Clean glass on a regular basis. Should glass become discolored
with creosote, follow this procedure for easy removal.
Burn fireplace with the outside air damper completely open
for 30-45 minutes. This will normally clean the glass and also
minimize ashes in the firebox.
Oven cleaner or a cleaner specifically designed for fireplace
may also be used. DO NOT use abrasive cleaners. Clean only
when glass is cool.
