3.2.20.5 Fireplace and Chimney Cleaning Requirements
The plan to install a gas fireplace Insert must include inspection and cleaning of the fireplace cavity and the entire chimney
system. The chimney top, especially masonry chimneys and wood framed chimney tops must be inspected and the top surface
must be repaired or replaced, if necessary. Unlined chimney flues are the most vulnerable to mortar corrosion and damage.
These flues must be inspected and repair must be done before dropping the flex vent liner for this Insert.
If you encounter a badly deteriorated or completely damaged firebox, do not proceed. These damaged structures must be
reviewed by structural Engineers and Local Building Code officials must approve the repair work prior to this Insert being
installed in such a damaged cavity.
Mendota requires that the fireplace cavity and chimney system be cleaned per the Chimney Safety
Institute of America recommendation prior to installati on of a Mendota gas fired Insert.
The Chimney
Safety Institute of America recommends that open masonry fireplaces should be swept at 1/8" of sooty
buildup, and sooner if there is any glaze present in the system. Thi s is considered to be enough fuel build up
to cause a chimney fire capable of damaging the chimney or spreading to the home. Factory -built fireplaces
should be swept when any appreciable buildup occurs. The logic is that the deposit is quite acidic and can
shorten the life of the fireplace.

WARNING: Failure to inspect and repair or replace damaged or dilapidated chimney flue, firebox or
chimney top caps can lead to odor emissions, water penetration and damage to electronic component s of
this gas Insert or damage to other home structures. This omission to inspect, repair or replace as necessary
will void all applicable warranties on this product.
3.2.20.6 Types of Chimney Flues
Chimney flues can vary in shape, size and type. During inspection, make note of the type of the flue system used. Professionally
clean and make any repairs before installing a Mendota gas Insert. Especially, pay attention to unlined flues which may have
missing or severely damaged mortar joints.
