WARNING
INSTALLER
• 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

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.

It is normal for fireplaces fabricated of steel
to give off some expansion and/or contraction
noises during the start up or cool down cycle.
Similar noises are found with your furnace heat
exchanger or car engine.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is not unusual for gas fireplace to give off some
odor the first time it is burned. This is due to the
manufacturing process.

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.
Your fireplace is approved to be vented either through the
side wall, or vertical through the roof.
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
• Be aware of electrical wiring locations in walls and
rooftops.

proved 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 raito requirements or clearance considerations
detailed in this manual.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting which incorporates the twist 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.
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

• Installation other than permitted by these instructions.
• Only MHSC venting components specifically ap-
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.

Twist Lock Pipes
When using twist 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 telescopic vent section used in the system.
To join twist lock pipes together, simply align the beads of the male end with the grooves of the female end, twisting the pipe until the flange on the female end contacts external flange on the male
end. It is recommended that you secure the joints with three (3) sheet metal screws, however, this
is not mandatory with twist lock pipe. Figure 11
To make it easier to assembly the joints, we suggest putting a lubricant (Vaseline or similar) on the
male end of the twist lock pipe prior to assembly.

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.
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
m), the horizontal run to the face of the outer wall must not
exceed 8Z\x’ (2.6 m).

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.

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.

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
drainage to be installed around the termination area.
If installing a snorkel, a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run 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).
1. Establish vent hole through the wall. Page 20, Figure
25
2. Remove soil to a depth of approximately 16” (406 mm)
below base of snorkel. Install drain pipe. Install window
well (not supplied). Refill hole with 12” (305 mm) of
coarse gravel leaving a clearance of approximately 4”
(102 mm) below snorkel. Figure 30
3. Install vent system.
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” snorkel collars.
6. Slide the snorkel into the vent pipes and secure to the
wall.
7. Level the soil so as to maintain a 4” (102 mm) clearance
below snorkel. Figure 30

check gas type
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.
A qualified installer or service person must
connect appliance to gas supply. Follow
all local codes.
CAUTION
WARNING
Install gas piping to fireplace / burner system location
For propane/LP units, never connect fireplace
directly to the propane/LP supply. This burner
system requires an external regulator (not
supplied). Install the external regulator between
the burner system and propane/LP supply.
installation items needed
Before installing fireplace and burner system, make sure you have the items listed below.
• External regulator • Piping (check local codes)
• Sealant (resistant to propane/LP gas)
(supplied by installer)
• Equipment shutoff valve*
• Test gauge connection*
• Sediment trap (recommended) • Tee joint
• Pipe wrench
• approved flexible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certified equipment shutoff valve from your dealer.
External
Regulator
100 lb. (min)

Down
CAUTION
For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do not
reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with the vent
pointing down as shown in Figure 39. Pointing the vent down protects it from freezing rain or sleet.
Use only new black iron or steel pipe. Internally
tinned copper or copper tubing can be
used per National Fuel Code, Section 2.6.3,
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 (BTU/hr). Undue pressure loss will
occur if the pipe is too small.
When using copper of flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.

Figure 38
CAUTION
WARNING
CDV7 Series Gas Fireplace
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 ANSI.Z223.1, NFPA54. In Canada CSA-B149
(1 or 2) Installation Code.
CAUTION
A listed manual shutoff valve must be installed upstream
of the appliance. Union tee and plugged 1/8" NPT pressure tapping point should be installed upstream of the
appliance. Figure 40
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.
Use pipe joint sealant that is resistant to liquid
petroleum (LP) gas.
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 40. 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.

cleaning and maintenance
Turn off gas before servicing fireplace. It is
recommended that a qualified service technician
perform these check-ups at the beginning of
each heating season.
Burner, Pilot and Control Compartment
Keep the control compartment, logs, and burner areas surrounding the logs clean by vacuuming or
brushing at least twice a year. Make sure the burner porting, pilot air opening and burner air opening
are free of obstructions at all times.
Pilot Flame
The flames from the pilot should be visually checked as soon as the heater
is installed and periodically during normal operation. The pilot flame must
always be present when the fireplace is in operation. Figure 55. The pilot
flame has three distinct flames, one engulfing the thermopile, one engulfing
the thermocouple, and the other reaching to the main burner.

pilot flame
The flames from the burner should be visually checked as soon as the
heater is installed and periodically during normal operation. In normal operation, at full rate, and
after operating for about 15 to 30 minutes, the flame should be yellow and slightly taller than the
rear log. Figure 56
If the flame is blue and only in the center, turn
off unit and let cool. After unit is cool, remove
logs and check to make sure rock wool is
placed correctly. Replace logs.
NOTE: The type of installation, vent system
configuration, and wind effects may cause the
flame patterns to vary.

cleaning and maintenance
CDV7 Series Gas Fireplace
Vent System
The fireplace and venting system should be inspected before initial use and at least annually by a qualified field service person. Inspect the external vent cap on a regular basis to make sure that no debris is
interfering with the airflow. Inspect entire venting system to ensure proper function.
Glass Door
Thoroughly clean the inside of the glass door after using the fireplace for ten hours. Periodically clean
the glass door as necessary.
When cleaning the glass, remember:
•
•
•
•
•
•
Do not remove the glass when hot. Allow glass to cool before removal.
NEVER use abrasive materials.
Keep children and pets a safe distance away.
Never operate the fireplace without the glass door properly secured.
Never operate the fireplace if the glass is broken.
Replace any glass that is chipped, cracked, or broken. Replacement glass door assemblies MUST
be supplied by the fireplace manufacturer ­– No substitute materials may be used.
• Handle glass door with care to avoid striking or scratching it on hard objects.
To clean glass door, follow “Glass Removal” procedure outlined in the Final Installation section. Film
deposit on the inside of the glass should be cleaned off using a nontoxic, non-corrosive, non-abrasive,
mild-cleaning solution. Simply apply an adequate amount to the glass and wipe off with a damp cloth.
After all maintenance has been completed, re-install glass door.
Logs
Leave logs installed in the fireplace for cleaning. Vacuum surface of the logs with a brush attachment. If
logs must be removed for cleaning, handle carefully by holding gently at each end. Gloves are recommended to prevent skin irritation from ceramic fibers. If skin becomes irritated, wash gently with soap and
water. Vacuum surface of logs with brush attachment or brush logs with a soft bristle brush (i.e. clean,
dry paintbrush). To place logs back in the fireplace, Refer to “Log Placement” section in this manual.
NOTE: Do not use fluids to clean ceramic fiber logs.
Rock wool
Replace or add rock wool as required following installation instructions in the Final Installation section
of this manual.

troubleshooting
ACTION
A. Open door and check to make sure wire is connected to
ignitor.
B.Check for spark at electrode and pilot. If no spark and
electrode wire is properly connected, replace pilot
assembly.
C. Check remote/manual shut off valve from fireplace. Low
pressure can be caused by bent lines, restricted lines,
low pressure line pressure. Consult with plumber or gas
supplier.
D. Check Propane/LPG tank. Refill tank.
A. Check that thermocouple flame impinges on thermocouple. Clean and/or adjust pilot for maximum flame
impingement. Ensure that the thermocouple connection
at the gas valve is fully inserted and tight.
Disconnect the thermocouple from the valve, place one
millivolt lead wire on the tip of the thermocouple and the
other meter lead wire on the thermocouple copper lead.
Start the pilot and hold the valve knob in. If the millivolt
reading is less than 15 mV, replace pilot assembly.
B.If thermocouple is producing more than 15 mV, replace
faulty valve.
A. Check switch and wire for proper connection. Place
jumper wires across terminals of switch. If burner comes
on, replace defective switch.If the switch is OK, repeat
the same procedure on remote control If burner comes
on, replace remote control.
Place jumper wire across wire at gas valves (terminals
marked TH and TP/TH). If burner comes on, wires are
faulty or connections are bad. Replace wire.
B.If pilot flame is not close enough to the thermopile, adjust
pilot flame.
C.Check thermopile wire connections to make sure all
are tight and that the thermopile is fully inserted into
pilot assembly. Check thermopile with a millivolt meter.
Connect leads to TP and TP/TH terminals on the control
valve. If meter reading is below 325 mV, replace pilot
assembly.
D.Turn valve knob to “On” and switch to “ON.” Take a reading at the thermopile leads (TP & TP/TH) on the valve.
If the meter reads greater than 175 mV and the burner
does not light, replace defective valve.
