Installing the Gas Fireplace
manufacturer) to ensure that adequate combustion air is
provided for proper function of this fireplace. Fireplaces
take up a large volume of replacement air from outside
the house and if the house is of airtight construction,
smoke spillage may occur if proper draft is not achieved.
4) There are many conditions beyond a manufacturer
’s
control regarding improper fireplace operation. The
manufacturer cannot ensure
“smoke free” operation,
nor can the manufacturer take on the responsibility
for problems with surrounding construction; chimneys
that have not been built at the right heights; system
drafts caused by faulty mechanical systems; adverse
weather conditions or any other inclement environmental
situations over which the manufacturer has no control.
5) Inspect all fireplace & chimney components for evidence
of damage prior to starting installation. Consult your local
distributor for replacement parts if necessary.
6) Under no circumstances should you make any
adjustments or modifications to the chimney system
during the installation procedure. If you do, you are not
only liable for negating the warranty, but you could very
well cause a serious malfunction of the fireplace. You
must follow your chimney manufacturer
’s instructions.
Fireplace Heights
When installed, the maximum overall height of the
Chimney System is 40 feet. The minimum installed height
of the completed Chimney System is 14 feet with a straight
flue stack, 17 feet if the chimney includes one or two offset
sections.
Supporting Floor Systems
It is the ultimate responsibility of the installer to ensure that
proper concrete slab supports are used.
WARNING
to the licensed design professional and/or
building contractor: It is your responsibility to be certain that
the Mason-Lite can be properly supported by the combustible
floor system on which the fireplace will rest.
