ing and slide unit back until nailing flanges  
touch side framing.  
To determine safest and most efficient location  
for fireplace, you must take into consideration  
the following guidelines:  
4. Check level of fireplace and shim with  
sheet metal if necessary.  
1. Location must allow for proper clearances  
(see Figures 1 and 2).  
5. Before securing fireplace to prepared  
framing, ember protector must be placed  
between hearth extension (not included)  
and under bottom front edge of fireplace  
to protect against glowing embers falling  
through. If fireplace is to be installed on  
a raised platform, a Z-type ember protec-  
tor (not included) must be fabricated to  
fit your required platform height. Ember  
protector should extend under fireplace a  
minimum of 1 1/2". Ember protector should  
be made of galvanized sheet metal (28  
gauge minimum) to prevent corrosion.  
2. Consider a location where fireplace will  
not be affected by drafts, air conditioning  
ducts, windows or doors.  
3. A location that avoids cutting of joists or  
roof rafters will make installation easier.  
4. An outside air kit is available with this  
fireplace (see Optional Outside Air Kit on  
page 7).

HEARTH ExTENSION  
Seal Gap  
Fireplace Front  
Ember Protector  
A hearth extension projecting a minimum of  
20" in front of and a minimum of 12" beyond  
each side of fireplace opening is required to  
protect combustible floor construction in front  
of fireplace. Fabricate a hearth extension  
using a material which meets the following  
specifications: a layer of noncombustible,  
inorganic material having a thermal conductiv-  
ity of K=0.84 BTU IN/FT, HR. F (or less) at 1"  
thick. For example, if material selected has  
a K factor of 0.25, such as glass fiber, the  
following formula would apply:

is to be covered, use noncombustible mate-  
rial such as tile, slate, brick, concrete, metal,  
glass, marble, stone, etc. Provide a means  
to prevent hearth extension from shifting and  
seal gap between fireplace frame and hearth

CHIMNEY PIPE  
Style Crest, Inc chimney system consists of  
12", 18", 24", 36" and 48" snap-lock, double-  
wall pipe segments, planned for maximum  
adaptability to individual site requirements.  
Actual lengths gained after fitting overlaps  
must be taken into consideration (lineal  
gain) and are given in lineal gain chart (see  
Figure 8).  
* The lineal gain for the terminations is  
measured to the flue gas outlet height.  
Figure 8 - Lineal Gain  
Lineal gain is actual measurable length of a  
part after two or more parts are connected.

gether, it is important to assure joint between  
chimney sections is locked. Check by pulling  
chimney upward after locking. Chimney will  
not come apart if properly locked. It is not  
necessary to add screws to keep chimney to-  
gether (exception - see Figure 11, page 9).  
Each double wall chimney section consists  
of a galvanized outer pipe, a stainless steel  
inner flue pipe and a wire spacer. Pipe sec-  
tions must be assembled independently as  
chimney is installed. When connecting chim-  
ney directly to fireplace, inner flue pipe sec-  
tion must be installed first with lanced side  
up. Outer pipe section can then be installed  
over flue pipe section with hemmed end up.  
Press down on each pipe section until lances  
securely engage hem on fireplace starter.  
Wire will assure proper spacing between  
inner and outer pipe sections.  
USING ELBOW OFFSETS (30E-8DM)  
1. To achieve desired offset, you may install  
combinations of 12", 18", 24", 36" and  
48" length of double wall pipe (see offset  
chart, page 7, and Figure 9).  
Note: For systems with 2 elbow sets, mini-  
mum height is 22 feet. Maximum height  
for any system is 50 feet.  
Note: For Canada, use chimney parts des-  
ignated HT.  
2. Chimney weight above offset rests on  
return elbow. Straps must be securely  
nailed to rafters or joists (see Figure 10,  
details A and B, page 9).  
WARNING:Openingincollar  
around chimney at top of fire-  
place must not be obstructed.  
Never use blown insulation to  
fill chimney enclosure.  
3. Maximum length of pipe between supports  
(return elbow or 12S-8DM) is 6' of angle  
run. Maximum of two 6' angle run sections  
per chimney system (see Figure 9).  
4. All pipe connections between offset and  
return must be secured with two screws  
on outer pipe only (see Figure 11, page  
9). Do not penetrate inner stainless.  
Continue to assemble chimney sections as  
outlined, making sure that both inner and  
outer pipe sections are locked together. When

Firestop spacers are required at each point  
where chimney penetrates a floor space.  
Their purpose is to establish and maintain  
required clearance between chimney and  
combustible materials. When pipe passes  
through a framed opening into a living space  
above, firestop must be placed onto ceiling  
from below as shown in Figure 12.  
5. Add next sections of pipe until end  
penetrates roof line. Check to see that  
proper clearances are maintained. Extend  
chimney by adding sections of double wall  
pipe until pipe is minimum of 30" above  
highest point of roof cutout. Termination  
and chimney must extend a minimum of  
36" above highest point where it passes  
through roof.  
They also provide complete separation from  
one floor space to another or attic space as  
required by most codes. When double wall  
pipe passes through a framed opening into  
an attic space, firestop must be placed into  
an attic floor as shown in Figure 13.

Tomaintaina2"clearancetopipeonaroofwith  
a pitch, a rectangular opening must be cut.  
1. Determine center point where pipe will  
penetrate the roof.  
2. Determine center point of the roof. Pitch  
is the distance the roof drops over a given  
span, usually 12".A6/12 pitch means that  
the roof drops 6" for each 12" measure  
horizontally down from roof rafters.  
Installing Flashing on a Metal Roof  
When installing flashing on a metal roof, it  
is required that putty tape be used between  
flashing and roof. Flashing must be secured  
to roof using #8 x 3/4" screws and then sealed  
with roof coating to prevent leakage through  
screw holes. A roof coating must also be ap-  
plied around perimeter of flashing to provide  
a proper seal.  
3. Use roof opening chart (Figure 14) to  
determine correct opening length and  
flashing required.

WARNING: If the fireplace  
has been used for wood burn-  
ing, firebox and chimney must  
becleanedofsoot,creosoteand  
ashes be a qualified chimney  
cleaner. Creosote will ignite if  
heavily heated.  
WARNING: When using  
a decorative vented gas log,

operaTion and MainTenance  
GLASS DOORS  
Glass doors are standard with this fireplace.  
When fireplace is in operation, doors must be  
fully opened or fully closed position only or a  
fire hazard may be created (see Figure 23).  
Doors Fully Closed  
Fireplace Front  
A fireplace equipped with glass doors oper-  
ates much differently than a fireplace with an  
open front. A fireplace with glass doors has a  
limited amount of air for combustion. Exces-  
sive heat within fireplace can result if too large  
a fire is built or if combustion air gate is not  
completely open.  
The following tips should be used to assure  
that both fireplace and glass door retain  
their beauty and function properly. Both the  
flue damper and glass doors must be fully  
opened before starting a fire. This will provide  
sufficient combustion air and maintain safe  
temperatures in firebox.  
Doors Fully Opened  
Fireplace Front  
Figure 23 - Glass Doors  
Cleaning Glass  
IMPORTANT: The glass must be allowed  
to warm slowly and evenly. Tempered glass  
will withstand a gradual temperature rise to  
550° F, which is more than a normal fire will  
generate. Such materials as pitch/wax laden  
logs, very dry mill end lumber and large  
amounts of paper or cardboard boxes can  
create an excessively hot fire and should not  
be burned in this fireplace. Always keep fire  
back from doors and never allow flames to  
contact glass.  
Clean glass with any commercial glass  
cleaner or soap and water. Do not use any  
abrasive material to clean the glass. Do not  
clean glass with any cool water if glass is still  
hot from fire and smoke.  
A gas line or gas log lighter may be installed  
for the purpose of installing a vented or vent-  
free decorative gas appliance incorporating an  
automatic shutoff device and complying with  
the Standard for Decorative Gas Appliances  
for Installation in Vented Fireplaces, ANSI  
Z21.60 or American Gas Association draft  
requirements for Gas Fired Log Lighters for  
Wood Burning Fireplaces, Draft NO. 4 dated  
August, 1993.  
WARNING: Fireplaces  
equipped with glass doors  
should be operated only with  
doorsfullyopenedordoorsfully  
closed.Doors,ifleftpartlyopen,  
may draw gas and flame out of  
the fireplace opening creating  
risks of both fire and smoke.  
If you wish to install an unvented (vent-free)  
gas log set, only unvented gas log sets which  
have been found to comply with the standard  
for unvented room heaters,ANSI Z21.11.2 are  
to be installed in this fireplace.
