OWNER
Please retain these instructions for future reference.
• Read this owner’s manual carefully and completely before trying to assemble, operate,
or service this fireplace.
• Any change to this fireplace or its controls can be dangerous.
• Improper installation or use of this fireplace can cause serious injury or death from
fire, burns, explosions, electrical shock and carbon monoxide poisoning.
This fireplace is a vented product. This fireplace must be
properly installed by a qualified service person. The glass
door must be properly seated and sealed. If this unit is not
properly installed by a qualified service person with glass
door properly seated and sealed, combustion leakage can

CARBON MONOXIDE POISONING: Early signs of carbon
monoxide poisoning are similar to the flu with headaches,
dizziness and/or nausea. If you have these signs, the fireplace may not have been installed properly. Get fresh air
at once! Have the fireplace inspected and serviced by a
qualified service person. Some people are more affected
by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia,
those under the influence of alcohol, and those at high
altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The
odor helps you detect a gas leak. However, the odor added
to these gases can fade. Gas may be present even though
no odor exists.

to do so could result in serious injury, property damage or loss of life. Operation of
improperly installed and maintained venting system could result in serious injury,
property damage or loss of life.
installation precautions
Consult local building codes before beginning the
installation. The installer must make sure to select the
proper vent system for installation. Before installing vent
kit, the installer must read this fireplace manual and vent
kit instructions.
Only a qualified installer/service person should install venting system. The installer must follow these safety rules:
• Wear gloves and safety glasses for protection.
• Use extreme caution when using ladders or when
on rooftops.
• Be aware of electrical wiring locations in walls and
ceilings.
The following actions will void the warranty on your venting system:
• Installation of any damaged venting component.
• Unauthorized modification of the venting system.
• Installation of any component part not manufactured
or approved by MHSC.
Installation other than permitted by these instructions.
Your fireplace is approved to be vented either through the
side wall, or vertical through the roof.
• Only MHSC venting components specifically approved and labelled for this fireplace may be
used.
• Flexible UL1777 listed venting may be used in any
venting application where rigid direct vent components
can be used. All restrictions, clearances and allowances that pertain to the rigid piping apply to the flexible
venting.
Flex kits may not be modified. Flex kits may be added
to the end of a vent run made of rigid vent sections
using pipe manufacturer's approved flex to pipe adapters. This may occur only if doing so does not violate
any of the venting length, height, routing, horizontal to
vertical ratio requirements or clearance considerations
detailed in this manual.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting which incorporates the T-lock pipe
must be installed on a level plane without an inclining
or declining slope.
• Horizontal venting which incorporates the use of flex
venting shall have an inclining slope from the unit of 1”
(25 mm) per 24” (610 mm).
There must not be any obstruction such as bushes, garden sheds, fences, decks or utility buildings within 24”
(610 mm) from the front of the termination hood.
Do not locate termination hood where excessive snow or
ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental
blockage of venting system. When using snow blowers,
make sure snow is not directed towards vent termination
area.
Location of Vent Termination
It is imperative the vent termination be located observing
the minimum clearances as shown on following page.
WARNING
Failure to follow these instructions will
void the warranty.
General Venting
This fireplace must be vented to the
outside. The venting system must NEVER
be attached to a chimney serving a
separate solid fuel burning appliance.
Each gas appliance must use a separate
vent system. Do not use common vent
systems.
WARNING
NOTICE
•
DVBL7 Series Gas Fireplace
Always maintain minimum clearances around vent systems. The minimum clearances to
combustibles for horizontal vent pipe are 3" at the top* and 1" at the sides and bottom of the
vent system until the pipe penetrates the nearest vertical wall (1" required). A 1" minimum
clearance all around the pipe must be maintained at outside wall and on vertical runs. Do not
pack the open air spaces with insulation or other materials. This could cause high temperatures
and may present a fire hazard.
* Unless the vertical run is 7Z\x feet or higher (top vent units only), the clearances for the
horizontal run is 1" at the top.

T-Lock Pipes
How to Use the Vent Graph
When using unitized T-Lock pipe it is not necessary to
use sealant on the joints. The only areas of the venting
system that need to be sealed with high temperature silicone sealant are the sliding joints of any telescope vent
sections used in the system.
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the relationship between the vertical and horizontal dimensions
of the vent system.
To join T-Lock pipes together, simply align both inner and
outer pipes with the next section. Align the internal beads
of the female end with the T-channels of the male end.
Figure 10

Indentations
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this dimension on the Sidewall Vent Graph, Figure 12, locate
the point intersecting 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.
EXAMPLE A:
If the vertical dimension from the floor of the unit is 11’ (3.4
m) the horizontal run to the face of the outer wall must not
exceed 14’ (4.3 m).
EXAMPLE B:
If the vertical dimension from the floor of the unit is 7’ (2.1

Horizontal sections of this vent system require a minimum of 3" clearances
to combustibles at the top of the flue and 1" clearance at the sides and
bottom until the flue penetrates the outside wall. A minimum 1" clearance
all around the flue is acceptable at this point of penetration.
If the vertical rise is 71/2 ft. or more, only a 1" clearance is needed on top
of any horizontal run.
Vertical sections of this vent system require a minimum of 1" clearance to
combustibles on all sides of the pipe.

It is best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the flue collar of the fireplace (or the top of the
Transition Elbow) to the face of the outer wall.
Horizontal plane means no vertical rise exists on this portion of the vent assembly.
• The maximum number of 90° elbows per side wall installation is three (3). Figure 14
• If the min. 12" rise with a 90° elbow is fitted directly
on top of the first 12" section, the maximum horizontal
vent run before the termination or a vertical rise is 36”
(914 mm). Figure 15
• If a 90° elbow is used in the horizontal vent run (level
height maintained) the horizontal vent length is reduced by 36” (914 mm). Figures 15 & 16. This does
not apply if the 90° elbows are used to increase or
redirect a vertical rise. Figure 14

the horizontal vent it must be reduced to 17’ (5.2 m).
In Figure 17, dimension A plus B must not be greater than
17’ (5.2 m)
• The maximum number of 45° elbows permitted per installation is six (6). These elbows can be installed in
either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run, the
length of the horizontal run MUST be reduced by 18”
(457 mm). This does not apply if the 45° elbows are
installed on the vertical part of the vent system.

Step 1
Locate vent opening on the wall. It may be necessary to
first position the fireplace and measure to obtain hole location. Depending on whether the wall is combustible or
noncombustible, cut opening to size. Figure 18 (For combustible walls first frame in opening.)
NOTE: When using flex vent, the opening will have to be
measured according to the 1/2” (13 mm) rise in 12” (305
mm) vent run.
Combustible Walls: Cut a 9B\,”H x 9B\,”W (244 x 244 mm)

Install the unitized T-lock vent pipe to the appliance collar,
following T-Lock directions on Page 14. It is not necessary to seal this connection. If a 45° elbow is being used
attach the elbow to the appliance in the same manner
then attach the venting to the elbow.
20301763
Step 6
Use appropriate length of pipe sections - telescopic or
fixed - and install. The sections which go through the wall
are packaged with the starter kit, and can be cut to suit if
necessary.

Sealing vent pipe and firestop gaps with high temperature sealant will restrict cold air being drawn in
around fireplace.
Step 7
Guide the vent terminations 4” and 7” collard into their
respective vent pipes. Double check that the vent pipes
overlap the collars by 2” (51 mm). Secure the termination to the wall with screws provided and caulk around
the wall plate to weatherproof. As an alternative to screwing the termination directly to the wall, you may also use
expanding plugs or an approved exterior construction adhesive. You may also attach the termination with screws
through the inner body into the 4” vent pipe, however for
this method, you must extend the 4” pipe approximately
6” (152 mm) beyond the outer face of the wall.
Support horizontal pipes every 36” (914
mm) with metal pipe straps.

Install the four (4) spacer springs on the 4” flex vent pipe.
When installing the spacer springs around the 4” pipe,
stretch the spring to approximately 15” (381 mm), wrap
the spring around the pipe and interlock the ends of the
spacer spring approximately 2” (51 mm). Measure 18C\v”
(476 mm) from the end of the pipe. Place the next spring
5” (127 mm) from the previously installed spring. Place
the next spring 6” (152 mm) from the last spring. Finally
place the last spring 12” (305 mm) from the last spring
installed. Figure 21

BELOW GRADE INSTALLATION
When it is not possible to meet the required vent terminal
clearances of 12” (305 mm) above grade level, a snorkel kit is recommended. It allows installation depth down
to 7” (178 mm) below grade level. The 7” (178 mm) is
measured from the center of the horizontal vent pipe as it
penetrates through the wall.
Ensure the sidewall venting clearances are observed.
If venting system is installed below ground, we recommend a window well with adequate and proper
FP1475
drainage to be installed around the
termination area.
If installing a snorkel, a minimum 24”
mm) vertical
flex(610

rise is necessary. The maximum horizontal
4/04 djtrun with the
24” vertical pipe is 36” (914 mm). This measurement is
taken from the collar of the fireplace (or transition elbow)
to the face of the exterior wall. See the Sidewall Venting
Graph for extended horizontal run if the vertical exceeds
24” (610 mm).

DVBL7 Series Gas Fireplace
Use proper gas type for the fireplace you are installing.
If you have conflicting gas type, do not install fireplace.
See dealer where you purchased the fireplace for proper
fireplace for your gas type or conversion kit.
Install gas piping to fireplace /
burner system location
installation items needed
Before installing fireplace and burner system, make sure
you have the items listed below.
• Piping (check local codes)
• Sealant (resistant to propane/LP gas)
• approved flexible gas line with gas connector (if
CAUTION
allowed by local codes — not provided)
• Equipment shutoff valve*
• Sediment trap (recommended) • Tee joint
• Pipe wrench
• External regulator (supplied by installer) - LP Only
• Test gauge connection*
* An equipment shutoff valve with a plugged tap is an
acceptable alternative to test gauge connection.
Use only new black iron or steel pipe.
Internally tinned copper or copper tubing
can be use, providing gas meets hydrogen
sulfide limits, and where permitted by local
codes. Gas piping system must be sized to
provide minimum inlet pressure (listed on
data plate) at the maximum flow rate (kw).
Undue pressure loss will occur if the pipe
is too small.
WARNING
When using copper or flex connectors use only fittings
approved for gas connections. The gas control inlet is RP
1/2"-14 straight pipe thread.
A qualified installer or service person must
connect appliance to gas supply. Follow all
local codes.
CAUTION
check gas type
A manual shutoff valve must be installed
upstream of the appliance. Union tee and
plugged pressure tapping point should be
installed upstream of the appliance. Figure
32
NOTE: The gas line connection may be made using 1/2"
rigid tubing or an approved flex connector. Since some
municipalities have additional local codes it is always best
to consult your local authorities and the current edition of
the National Fuel Gas Code.
IMPORTANT: Install main gas valve (equipment shutoff
valve) in an accessible location. The main gas valve is for
turning on or shutting off the gas to the fireplace.
Check your building codes for any special requirements for
locating equipment shutoff valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged burner system valve.
We recommend that you install a sediment trap/drip leg in
supply line as shown in Figure 32. Locate sediment trap/
drip leg where it is within reach for cleaning. Install in piping
system between fuel supply and burner system. Locate
sediment trap/drip leg where trapped matter is not likely
to freeze. A sediment trap collects moisture and contaminants and keeps them from going into the burner system
gas controls. If sediment trap/drip leg is not installed or is
installed wrong, burner system may not run properly.
