LOCATING FIREBOX
Plan where you will install the firebox. This will
save time and money later when you install the fire-
box. Before installation, consider the following:
1. Where the firebox will be located. Allow for
wall and ceiling clearances (see
Installation
Clearances,
page 7).
2. Everything needed to complete installation.
3. These models CANNOT be installed in a
bedroom or bathroom.
4. Proper air for combustion and ventilation (see
Air For Combustion and Ventilation
).
AIR FOR COMBUSTION
AND VENTILATION
WARNING: This firebox shall
not be installed in a confined
space or unusually tight construc-
tion unless provisions are provid-
ed for adequate combustion and
ventilation air. Read the following
instructions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
Todayʼs homes are built more energy efficient
than ever. New materials, increased insulation and
new construction methods help reduce heat loss
in homes. Home owners weather strip and caulk
around windows and doors to keep the cold air out
and the warm air in. During heating months, home
owners want their homes as airtight as possible.
While it is good to make your home energy effi-
cient, your home needs to breathe. Fresh air must
enter your home. All fuel-burning appliances need
fresh air for proper combustion and ventilation.
Exhaust fans, fireboxes, clothes dryers and fuel
burning appliances draw air from the house to
operate. You must provide adequate fresh air for
these appliances. This will insure proper venting
of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from
National Fuel
Gas Code ANSI Z223.1/NFPA 54, Section 5.3, Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three fol-
lowing ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
