Installing The Gas Line
The gas line must be installed before finishing the M38ODV-ST
fireplace. Natural Gas requires a minimum inlet gas supply pressure of
5.5" W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure
of 10" W.C. Provision must also be made for a 1/8" N.P.T. plugged
tappingand beaccessible fortestgauge connectionimmediately
upstream of the gas supply controls to the appliance. The fireplace gas
connection and the main operating gas valve is located behind the
removable brass trim at the bottom of the unit and need only be
attached to the gas line with an approved fitting, as required by the
applicable installation codes.
* After gas line is connected each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten any
areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected. Do
NOT use a flame of any kind to test for leaks.
Installing The Remote Switch
The M38ODV-ST is equipped with a remote-operated valve, located
behind the removable brass grille, to the right of the gas control valve
(refer to Figure 16.) The valve is pre-wired and completely self
contained to generate its own power. DO NOT connect any external
power to it.
Note: The switch location must not exceed 30' from the fireplace.

Top Vent Venting Runs
Before you install any venting, you must determine whether the venting
run will be acceptable. Unacceptable venting can affect the fireplace's
combustion.
for installations with horizontal venting runs of 0-16 feet, use the
vent graph, as described below
the maximum horizontal vent run is 16 feet.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 4) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installationisacceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 72", and the horizontal
run to the wall flange of the vent termination is 120", this would be
anacceptableinstallation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 66" and the horizontal
run to the wall flange of the vent termination is 30", this would be
anacceptableinstallation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 48" and
the horizontal run to the wall flange of the vent termination is 84",
this would NOT be an acceptable installation.

Heat Shields
Due to high flue temperatures, heat shields are
required on all M38ODV-ST installations at the
point where the venting passes through the
wall to connect to the termination.
Using the heat shield, vent clearances at this
point are 1" to combustible construction.
Example:
A 10' section and an elbow used in conjunction with 3 ft. flex section
(PFL-3) will, when extended in a five foot chase, allow for a maximum
horizontal run of twelve and one-half feet from the centre of the
fireplace to outside wall and a minimum of 7'6" when retracted in
opposite direction. (See Figure 6 and 7.)
"D" flex sections and "E" solid sections may be used in conjunction with
oneanother toobtain differentpossible horizontallength installations.
NOTE: Flex section must not exceed maximum horizontal length of 3
feet. (See Figure 8.)

Finishing Around the Fireplace
Combustible mantels and mouldings may be safely installed over the top
and on the front of the fireplace provided that they do not project
beyond shaded area shown in Figure 11a. Side wall clearances are 0".
Combustible surrounds may be installed with 0" clearance to the side of
the fireplace as shown in Figure 11b.
Fireplace Facing
When selecting the finish material for your fireplace, it is important to
remember the following: TRIMS MUST NOT BE OBSTRUCTED IN
ANY WAY - to do so restricts the air supply for the control
compartments and heat exchanger it also prevents access for
servicing controls.
The face of the fireplace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must not
extend past the fireplace opening at all, because it will interfere with the
access to retainers for removal of glass door.
Mantels & Surrounds
NOTE: NationalCanadian GasAssociation manteltest requirements
are for fire hazard prevention to combustible materials.
New technology, to meet consumer and government demands for the
wise use of energy, has prompted us to manufacture many models of
fireplaces which are hot, fuel and energy efficient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above fireplace may be hot to touch.
We recommend careful consideration be given to the effects of
elevated mantel temperatures which may be in excess of product
design,for example: candles,plastic orpictures. This cancause
melting, deformation, discoloration or premature failure of T.V. and
radiocomponents.
Figure 11b. Combustible surrounds.
Figure 11a. Combustible mantles and facings.
Painting:
Special care is recommended by the Master Painters and Decorators
Association, when painting the fireplace surrounds, to select and apply
a quality Alkyd sealer prior to the applying of latex paints. This is to
prevent leaching of water from evaporation and causing a brownish
staining effect to paint over coats.

Always keep the fireplace area clear and free of combustible
materials, as well as gasoline and other flammable vapours and
liquids.
Do not use this appliance if any part has been under water.
Immediatelycallaqualifiedservicetechniciantoinspectthe
appliance and to replace any part of the control system and any gas
control which has been under water.
CAUTION
• Fireplace gas control must be in the “OFF” position and pilot
and main burners extinguished when cleaning appliance with
a vacuum.
• Glass and logs can get very hot. Handle only when cool.
Cleaning
When the fireplace is first activated, there may be some smoking and a
visible film may be left on the glass. This is a normal condition, and is
the result of burningthe protective coatings on new metal.
Glass must be cleaned periodically to remove any film (a normal bi-
product of combustion) which may be visible. Film can easily be
removed by removing the door, as shown on page 9. Handle the
door carefully, and clean it with non-abrasive glass cleaners. One of
the most effective products is Kel Kem.
Silicone seals on inner door during initial firing will "off gas", leaving
a visual deposit of a white substance on combustion chamber walls.
This can easily be removed by following the steps described above.
Use a vacuum cleaner or whisk broom to keep the control compart-
ment, burner, and firebox free from dust and lint.
Logs may be cleaned periodically with a vacuum to remove soot.
WARNING:
Do not attempt to clean glass when hot.
Do not clean glass with abrasive materials as any glass
etching may cause premature glass failure.
Pilot Burner Adjustment
1. Locate Pilot Adjustment Screw. (See figure 16.)
2. Turn Adjustment Screw until flame is proper size. (See figure 17).
3. After installing or servicing, leak test with a soap solution with main
burner on. Coat pipe and tubing joints, gasket etc. with soap
solution. Bubbles indicate leaks. Tighten any areas where the
bubblesappear until thebubbling stops completely.
