INSTALLATIONS REQUIRING ASSEMBLY TO
BE SECURED TO WALL
1  Some codes
require that assembly must be installed securely to
walk Remove baseboard. Baseboard will prevent proper instal-
lation of mantel. Baseboard must be altered to fit mantel.
2.
Mantel must be attached to either a wall stud or wall anchor. Use
:37" gauge stnp to determine correct height from floor to location
of mounting strips (sec Figure 9). Use
a level to
ensure 11101111t-
ing
strip is evenly balanced (see Figure 9). Adjust accordingly.
IMPORTANT:
Failure to balance mounting strips with a level
could result in uneven surfaces on fully assembled mantel.
3.
If predrilled holes of mounting strip
line up
with wall studs,
fasten mounting strip to wall with 2" screws. If
predrilled holes
of mounting strip do not line up with wall studs, drill new
holes in mounting strip or attach to wall with
wall anchors
(see step 4)
4. To use wall
anchors, drill hole at marked location
using 5/16"
drill bit. Fold wall anchor (see Figure
10),
and insert (wings
first) into hole. Tap anchor flush into wall.
For thin
walls (1/2"
or less), insert
red key into wall anchor and push to "pop" open
anchor wings (see Figure II).
IMPORTANT: Do not hammer
key! For thick walls (over 112" thick) or solid walls, do not
pop open wings.
5. Align predrilled holes in mounting strip with wall anchors.
Attach to wall anchors using 2" screws.
6. After final assembly drill small (1/16") pilot holes through
top
of mantel and into strip to keep nails from bending. Nail the top
of the assembly to the
strip with 1 '/4" finishing nails. Fill nail
holes with wood putty. Touch up paint on painted mantels.

AIR FOR COMBUSTION
AND VENTILATION
A WARNING: This fireplace
shall not be installed in a con-
fined space or unusually tight
construction unless provisions
are provided for adequate com-
bustion and ventilation air. Read
the following instructions to in-
sure proper fresh air for this and
other fuel-burning appliances in
your home.
Today's 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, fireplaces. 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 printer venting
of vented fuel-burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from
National Fuel
Gas Code, A A 151 Z223. UNITA 54. Sedion 53, Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three fol-
lowing ventilation classifications:
I. Unusually Tight Construction
2. Unconfined Space
3.
Confined Space
The information on pages 6through g will help you
classify your space and provide adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and
windows
may
provide enough fresh air for combustion and yen
Illation. However, in buildings of unusually tight
construction, you must provide additional fresh air.

AIR FOR COMBUSTION
AND VENTILATION
Continued
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10 - " kg per pa-sec-m
2 )
or less with openings gasketed or
sealed
and
b. weather stripping has been added on
openable windows and doors
and
c. caulking or sealants are applied to ar-
eas such as joints around window and
door frames, between sole plates and
floors, between wall-ceiling joints, be-
tween wall panels, at penetrations for
plumbing, electrical, and gas lines, and
at other openings.
If your home meets all of these three crite-
ria, you must provide additional fresh air.
See
Ventilation Air From Outdoors, pages.
If your home does not meet all of the three
criteria above, proceed toDetermining Fresh-
Alr Row For Fireplace Location, below.
Confined and Unconfined Space
The National Fuel Gas Code, ANSI 1223.I/NFPA
54 defines a confined space as a space whose vol-
ume is less than SO cubic feet pee 1,000 RR,
per
hour (4.8 in 3 per kw) of the aggregate input rating
of all appliances installed in that space and an un-
confined space as a space whose volume is not
less than 50 cubic feet per 1,000 Btu per hour (4.8
m 3 per kw ) of the aggregate input rating of all ap-
pliances installed in that space. Rooms communi-
cating directly with the space lit which the appli-
ances are installed*, through openings not fur-
nished with doors, are considered a part of the
unconfined Space.
*Adjoining rooms are communicating only if there
are doorless passageways or ventilation grills be-
tween them.
DETERMINING FRESH-AIR FLOW
FOR FIREPLACE LOCATION
Determining it Y ou Have a Confined or
Unconfined Space
Use this work sheet to determine if you have a
confined or unconfined space.
Space: Includes the room in which you will in-
stall fireplace plus any adjoining rooms with
doorless passageways or ventilation grills between
the rooms_
I. Determine the volume of the space (length x

Length x Width s Height =  cu. ft.
(volume of space)
Example: Space site id ft. (length) x 14 ft.

ume of space)
If additional ventilation to adjoining room is sup-
plied with grills or openings, add the volume of
these rooms to the total volume of the space.
2. Multiply the space volume by 20 to determine
the maximum Btu/Ht the space cart support.

AIR FOR COMBUSTION
AND VENTILATION
Continued
The space in the above example is a confined space
because the actual Btu/Hr used is more than the
maximum BM/Iir the space can support. You
must
provide additional fresh air. Your options are as
follows:
A. Rework worksheet, adding the space of an ad-
joining room. If the extra space provides an
unconfined space, remove door to adjoining
room or add ventilation grills between rooms.
See Ventilation Air From Inside Building
B. Vent MOM directly to the outdoors. See Venti-
lation Air From Outdoors_
C . Install a lower Btu/HI - fireplace, if lower Btuillr
size makes room unconfined.
If the actual Rtufblr used is less than the maxi-
mum Blair the space can support, the space is
an unconfined space. You will need no additional
fresh air ventilation.
AA
WARNING: If
the area in
which the fireplace may be op-
erated is smaller than that de-
fined as an unconfined space or
if the building is of unusually
tight construction, provide ad-
equate combustion and ventila-
tion air by one of the methods
described in the
National Fuel
Gas Code, ANSI Z223.1/NFPA
54 Section 5.3 or applicable lo-
cal codes,
VENTILATION AIR
Ventilation Air From Inside Building
This fresh air would come from an adjoining un-
confined space. When ventilating to an adjoining
unconfined space, you must provide two perma-
nent openings: one within
I 2" of the ceiling and
one within 12" of the floor on the wall connecting
the two spaces (sec options 1 and 2, Figure 4).
You can also remove dour into adjoining room (see
option I Figure 4). Follow the National Fuel Gas
Code, ANSI /223. 1/NFPA 54. Section 5.3. Air the
Combustion and Ventilation for required size of
ventilation grills or ducts.
Figure 4- Ventilation Air from inside
Building
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills
or ducts. You must provide two permanent open
ings: one within 12" of the ceiling and one within
12" of the floor. Connect these items directly to
the outdoors or spaces open to the outdoors. These
spaces include attics and crawl spaces. Follow the
National. Fuel Gas Code, ANSI /223.1/NEPA 54.
Section 53. Air for Cumbustiem and Ventilation
for required size of ventilation grills or duets.
IMPORTANT - Do not provide openings for inlet
or outlet air
into attic if attic has a thermostat-con-
trolled power vent. Heated air entering the attic
will activate the power vent.
