Since it is very important that the venting system  
maintainitsbalancebetweenthecombustionairintake  
and the flue gas exhaust, certain limitations as to vent  
configurations apply and must be strictly adhered to.  
Fig. 12  
STEP 3  
The graph showing the relationship between vertical and  
horizontal side wall venting will help to determine the  
various vent lengths allowable. Fig. 19.  
Measure from fireplace collar to face of outside wall (add 2"  
for vent pipe overlap. Mark pipes and cut to length. It is very  
important that the two pipes are flush with the outside wall  
once the fireplace is in its final location. Fig. 13.  
Minimum clearance between vent pipes and  
combustible materials is one (1") inch (25  
mm) on top, bottom and sides unless  
otherwise noted.  
STEP 4  
When vent termination exits through  
foundationlessthan20"belowsidingoutcrop,  
the vent pipe must flush up with the siding. A  
7DVSS must also be used.  
Slip 4" and 7" pipes onto respective flue collars. Make sure  
to fix to the fireplace collar the 4" pipe with three (3) screws  
before fixing the 7" pipe on the 7" collar. Both pipes must  
be on a level plane. Fig. 13.  
It is always best to locate the fireplace in such a way that  
minimizes the number of offsets and horizontal vent  
length.  
STEP 5  
Guide the vent termination 4" collar into the 4" pipe then the  
7" collar into the 7" pipe. Do not force the venting into  
position. If the pipes do not line up with the termination  
collars, disassemble pipes and reattach to the fireplace  
collar. (Fig. 13)  
The horizontal vent run refers to the total  
length of vent pipe from the flue collar of the  
fireplace to the face of the outer wall.  
Horizontal plane means no vertical rise  
exists on this portion of the vent assembly.  
STEP 6  
For some installations, it may be desireable  
to have some amount of the horizontal vent  
run immediately after the fireplace. A verti-  
cal rise must be used but can be located  
anywhere in the vent system, to meet the  
perimeters identified in the venting graph.  
Secure fireplace to floor through floor holes and adjustable  
frame drywall strip (nailing flange) to frame. (See Framing  
& Finishing Section)  
The maximum horizontal vent run is 20 feet (6100mm)  
when the vertical vent rise is 7.5 feet (2286mm). Fig. 14

installation is four (4), (includes 7DVRT90 off back of unit)  
The maximum number of 45 degree elbows permitted per  
side wall installation is two (2). These elbows can be  
installed in either the vertical or horizontal run.  
The maximum number of elbow degrees in a system is

For each 45 degree elbow installed in the  
horizontal run (while maintaining a constant  
horizontal plane), the length of the horizontal  
run MUST be reduced by 18" (457mm). This  
does not apply if the 45 degree elbows are  
installed on the vertical part of the vent  
system.  
If a 90 degree elbow is used in the horizontal  
vent run (level height maintained) the maxi-  
mum horizontal vent length is reduced by 36  
inches. Fig. 18. This does not apply if the 90  
degree elbows are used to increase or redi-  
rect a vertical rise.  
Example: According to the vent chart the maximum  
horizontal vent length is 20 ft.when the vertical height is 8  
ft. from fireplace base height. If one 90 degree elbow is  
required in the horizontal vent it must be reduced to 17 ft.

VERTICAL SIDEWALL INSTALLATION  
HOW TO USE THE VENT GRAPH  
1. Determine the height of the centre of the horizontal  
vent pipe exiting through the outer wall. Using this  
dimension on the Sidewall Vent Graph (Fig. 18),  
locate the point it intersects with the slanted graph  
line.  
2. From the point of this intersection, draw a vertical  
line to the bottom of the graph.  
3. Select the indicated dimension, and position the  
fireplace in accordance with same.  
STEP 1  
Locateventopeningonthewall. Itmaybenecessarytofirst  
position the fireplace and measure to obtain hole location.  
Depending on whether the wall is combustible or non-  
combustible, cut opening to size. Fig. 19.  
(For combustible walls first frame in opening).  
EXAMPLE A:  
VERTICAL SIDEWALL APPLICATION  
If the vertical dimension from the floor of the unit is 11  
feet (3352mm) the horizontal run to the face of the outer  
wall must not exceed 14 feet (4267mm).

BELOW GRADE INSTALLATIONS  
When it is not possible to meet the required vent terminal  
clearances of 12 inches (305mm) above grade level a  
model 7DVSKS vent kit is required. It allows installation  
depth of down to 7 inches (178mm) below grade level. The  
7 inches is measured from the centre of the horizontal vent  
pipe as it penetrates through the wall.  
If venting system is installed below ground,  
we recommend a window well with adequate  
and proper drainage.  
INSTALLATION  
Ensure sidewall venting clearances are observed.  
The maximum horizontal run with 24" (610mm)  
vertical rise is 36" (914mm) from the back of the  
fireplace to the face of the exterior wall. See  
vent graph (Fig. 18) for extended horizontal run  
if the vertical exceeds 24" (610mm).  
1. Establish vent hole through the wall. See page 12  
2. Remove soil to a depth of approximately 16"  
(406mm) below base of snorkel. Install window well  
(not supplied). Refill hole with 12" (305mm) of  
coarse gravel leaving a clearance of approximately  
4" (100mm)below snorkel. (Fig. 25)  
3. Install vent system. See page 12, Steps 2 through  
5.  
4. Ensure a watertight seal is made around the vent  
pipe coming through the wall.  
5. Apply high temperature sealant caulking (supplied)  
around the 4 and 7 inch 7DVSKS's snorkel collars.  
6. Slide into vent pipe and secure to the wall.  
7. Level the soil so as to maintain a 4"  
(100mm)clearance below snorkel (Fig. 25).

GENERAL INFORMATION ON ASSEMBLING  
THE TWIST LOCK VENT PIPES  
When using CFM Majestic twist lock pipe it is not neces-  
REAR VENTING APPLICATIONS  
sary to use silicone to seal the twist lock joints. The only  
areas that need silicone are the collars on the fireplace,  
the telescoping pipe (if used) and the horizontal termina-  
tion connection (when necessary).  
Note: It is not necessary to seal the vent pipe joints  
for any rear vent applications.  
To join the pipes together, simply align the beads of the  
male end with the grooves of the female end and while  
joining the two together, twist the pipe until the flange on  
the female end touches the external bead on the male  
end. Secure the joints with three sheet metal screws.  
Minimum clearances between vent pipe and com-  
bustible materials are as follows:  
Top  
Sides  
- 2" (50 mm)  
- 1" (25 mm)  
Bottom - 1" (25 mm)  
To make easier to assembly, we suggest putting lubri-  
cant (vaseline or similar) on the male end of the twist  
lock pipe.  
Note: Vent Starter Kit Model 7TDVRVT must be  
used in rear vent applications.

VERTICAL SIDEWALL APPLICATIONS  
VERTICAL SIDEWALL INSTALLATIONS  
Since it is very important that the venting system  
maintainitsbalancebetweenthecombustionairintake  
and the flue gas exhaust, certain limitations as to vent  
configurations apply and must be strictly adhered to.  
The maximum number of 90 degree elbows per side wall  
installation is four (4), (includes 7TDVRT90 off back of unit)  
The maximum number of 45 degree elbows permitted per  
side wall installation is two (2). These elbows can be  
installed in either the vertical or horizontal run.  
The graph showing the relationship between vertical and  
horizontal side wall venting will help to determine the  
various vent lengths allowable. Fig. 45.  
When one 90o elbow is installed directly onto another off  
the back of the fireplace the maximum horizontal vent  
length is 36" (914mm). Fig. 42.  
Minimum clearance between vent pipes and  
combustible materials is one (1") inch (25  
mm) on top, bottom and sides unless  
otherwise noted.  
MAXIMUM  
3' (914mm)  
When vent termination exits through  
foundationlessthan20"belowsidingoutcrop,  
the vent pipe must flush up with the siding. A  
7DVSS must also be used.  
It is always best to locate the fireplace in such a way that  
minimizes the number of offsets and horizontal vent  
length.  
7TDVRT90  
ELBOW  
Fig. 42  
The horizontal vent run refers to the total  
length of vent pipe from the flue collar of the  
fireplace to the face of the outer wall.  
SIDE VIEW  
Horizontal plane means no vertical rise  
exists on this portion of the vent assembly.  
For each 45 degree elbow installed in the  
horizontal run (while maintaining a constant  
horizontal plane), the length of the horizontal  
run MUST be reduced by 18" (457mm). This  
does not apply if the 45 degree elbows are  
installed on the vertical part of the vent  
system.  
For some installations, it may be desirable to  
have some amount of the horizontal vent run  
immediately after the fireplace. A vertical  
rise must be used but can be located any-  
where in the vent system, to meet the perim-  
eters identified in the venting graph.  
If a 90 degree elbow is used in the horizontal  
vent run (level height maintained) the maxi-  
mum horizontal vent length is reduced by 36  
inches. Fig. 43. This does not apply if the 90  
degree elbows are used to increase or redi-  
rect a vertical rise.  
The maximum horizontal vent run is 20 feet (6100mm)  
when the vertical vent rise is 7.5 feet (2286mm). Fig. 41  
MAXIMUM  
20 ft. (6100mm)  
Example: According to the vent chart the maximum  
horizontal vent length is 20 ft.when the vertical height is 7.5  
ft. from fireplace base height. If one 90 degree elbow is  
required in the horizontal vent it must be reduced to 17 ft.

1. Determine the height of the centre of the horizontal  
vent pipe exiting through the outer wall. Using this  
dimension on the Sidewall Vent Graph (Fig. 45),  
locate the point it intersects with the slanted graph  
line.  
90o elbow=3'  
2. From the point of this intersection, draw a vertical  
line to the bottom of the graph.  
3. Select the indicated dimension, and position the  
fireplace in accordance with same. (See examples  
Fig. 43).

of pipe section – telescopic or fixed  
– and install. The 20" section of  
pipe which goes through the wall is  
packagedwiththe7TDVSKkit,and  
can be cut to suit if necessary.  
When it is not possible to meet the required vent termi-  
nal clearances of 12 inches (305mm) above grade level  
a model 7TDVSKS vent kit is recommended. It allows  
installation depth of down to 7 inches (178mm) below  
grade level. The 7 inches is measured from the centre  
of the horizontal vent pipe as it penetrates through the  
wall.  
Sealing vent pipe and  
firestop gaps with high  
temperature sealant will  
restrict cold air being  
drawn in around fireplace.  
If venting system is installed below ground,  
we recommend a window well with adequate  
and proper drainage.  
STEP 6  
INSTALLATION  
(Fig. 53) Apply high temperature sealant to 4" and 7"  
collars one inch away from crimped end. Guide the vent  
terminations 4" and 7" collars into their respective vent  
pipes. Doublecheckthattheventpipesoverlapthecollars  
by 2". Secure the termination to the wall with screws  
provided and caulk around the wall plate to weatherproof.  
Ensure sidewall venting clearances are observed.  
The maximum horizontal run with 24" vertical  
rise is 36" (915mm) from the back of the  
fireplace to the face of the exterior wall. See  
vent graph (Fig. 45) for extended horizontal  
run if the vertical exceeds 24".

GLASS CLEANING  
It will be necessary to clean the glass periodically. During  
start-up condensation, which is normal, forms on the inside  
of the glass and causes lint, dust and other airborne  
particles to cling to the glass surface. Also initial paint  
curing may deposit a slight film on the glass. It is therefore  
recommended that the glass be cleaned two or three times  
with a non-ammonia household cleaner and warm water  
(we recommend gas fireplace glass cleaner). After that the  
glass should be cleaned two or three times during each  
heating season depending on the circustances present.

To obtain proper operation, it is imperative that the pilot  
and burner's flame characteristics are steady, not lifting  
or floating.  
Fig. 74  
INSPECTING THE VENTING SYSTEM  
Typically, the top 3/8" or 1/2" of the thermopile should be  
engulfed in the pilot flame. See Fig. 72.  
To adjust pilot burner (by a Qualified Service  
Representative)  
This appliance venting system was designed and con-  
structed to develop a positive flow adequate to remove flue  
gases to the outside atmosphere.  
1. Remove pilot adjustment cap.  
2. Adjust pilot screw to provide properly sized flame.  
3. Replace pilot adjustment cap.  
Any foreign objects in the venting system, except those  
designed specifically for the venting system, may cause  
spillage of flue gases.  
The primary air shutter is set at factory and should  
only be adjusted (if necessary) by a qualified service  
person.  
To inspect the venting system, make sure the main gas  
valve is off. Remove glass door (See Glass Door Re-  
moval). Using a flashlight, check the area above the baffle  
in the combustion dome. Clean if necessary.
