Installing The Fireplace Shell

The fireplace may be installed in any location that maintains proper clearances to air conditioning ducts, electrical wiring and plumbing. Safety, as well as efficiency of operation, must be considered when selecting the fireplace location. Try to select a location that does not interfere with room traffic, has adequate ventilation, and offers an accessible pathway for Direct Vent installation. Refer to page 4 – Vent Installation for more information.

*** If the standard elbow (MEL90) is used with the Low Clearance Sleeve (CRS30) the Top Clearance is 15″.

If the Low Clearance Sleeve (CRS30) is NOT used over the elbow, the Top Clearance is 35″.

Unprotected combustible walls which are perpendicular to the fireplace opening, must not project beyond the shaded area shown in Figure 19b.
For protection against freezing temperatures, it is recommended that outer walls of the chase be insulated with a vapour barrier. This will reduce the possibility of a cold-air convection current on the fireplace.

0″ clearance to corners only
Figure 3. Corner framing dimensions.
When installing a shelf over the top of the fireplace, the following guidelines must be adhered to: For Rear Vent models (MD34DR-2), the minimum clearance from the top of the fireplace to a shelf is 7″. For Top Vent models (MD34DT-2), the minimum clearance when using the CRS30 is 15″. (Minimum 1″ clearance must still be maintained around the vent pipes.)

Installation

Installing The Gas Line
The gas line must be installed before finishing the MD34-DV-2 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 tapping and be accessible for test gauge connection immediately 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.
Figure 5. Gas line access. During any pressure testing of the gas supply piping that excedes 1/2 psig (3.5 kPa), the appliance and its individual shutoff valve must be disconnected from gas supply system. When pressure testing the gas supply piping system at test pressures of less than or equal to 1/2 psig (3.5 kPa), the appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve.
Note: 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.

Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
n MD34-DV-2 fireplaces are certified for use with Montigo Standard Series (4″ / 7″) venting components
n Minimum 1″ clearance to combustibles required for vent pipes
n Use only certified Montigo vent components. (Use of other parts will void the Montigo warranty, and may impede the operation of the fireplace.)
n All joints must be secured with a minimum of two screws per joint
n Vent terminations must not be recessed in walls or siding
n Horizontal runs must be supported by a minimum of two supports per horizontal run. A minimusm of one screw on each side of support is also required
n Flex vent sections may be stretched up to 50% of their total length (eg. a 24″ section may be stretched to 36″)
n Maximum horizontal run for a flex section with no vertical rise is 3 feet.
n Flex vent sections over 3 feet must fall within the limits set by the venting graph and must have a minimum vertical rise of 3 inches per foot of flex.
n Solid vent sections may be cut less than half way from the tapered end
n Venting components can be used in any combination of solid/rigid pipe or flex pipe and in any orientation (Male connectors can face in any direction)
Vent Terminations
Selecting A Termination Location
Choosing your vent termination location will help to determine whether you need to use a top vent or rear vent fireplace. Figure 6, below, shows typical fireplace locations and the venting options they provide.
For a more detailed diagram of allowed termination locations, see Appendix B.

Installing The Remote Switch
The MD34-DV-2’s gas valve, located behind the lower brass trim, may be connected to a wall switch. The valve generates its own power. This is a millivolt circuit. Use only low voltage wire, and DO NOT connect any external power to it. Refer to Figure 28 for wiring requirements. Note: The switch location must not exceed 30′ from the fireplace.
Page 4

Figure 6. Fireplace locations and vent terminations.
Cautions:
n Vent terminations can be very hot. If the termination is less than 7 feet above a public walkway, it should be fitted with a certified Montigo Heat Guard. (Part no. MTKOG)
n Do not obstruct, or attempt to conceal, the vent termination. These actions will affect the operation of the fireplace, and may be hazardous.
n In heavy snow areas, take extra care to prevent snow buildup from obstructing the vent termination.

Installation Top Vent

Top Vent Venting Runs
For the MD34-DV-2, there are two types of installations: A) ThroughThe-Wall Installations and B) Vertical (Through-The-Roof) Installations.
A) Through-The-Wall Installations
Before you install any venting, you must determine whether the venting run will be acceptable. Unacceptable venting can affect the fireplace’s combustion.
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. 7) with an ‘X’.
If the ‘X’ falls on or above the top boundary of the shaded area, the installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84″ and the horizontal run to the wall flange of the vent termination is 36″, this would be an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 90″ and the horizontal run to the wall flange of the vent termination is 126″, this would be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 78″ and the horizontal run to the wall flange of the vent termination is 108″, this would NOT be an acceptable installation.

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 21a. Side wall clearances are 3″. Combustible surrounds may be installed with 3″ clearance to the side of the fireplace as shown in Figure 21b.
Fireplace Facing
When selecting the finish material for your fireplace, it is important to remember the following: BRASS 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.

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 or pictures. This can cause melting, deformation, discoloration or premature failure of T.V. and radio components.

Mantels & Surrounds
NOTE: National Canadian Gas Association mantel test 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.

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.

Adjusting the Burner
Raising or lowering the Flame Height
The MD34-DV-2 fireplace is equipped with an adjustable burner, allowing you to raise or lower the flames. Operating the control knob as described below will adjust both the main burner and the ember burner. n To raise the flame height, turn the black knob (located behind the
lower trim) counterclockwise. n To lower the flame height, turn clockwise.
Gas Control Knob (Shown in “Pilot” postion.) Figure 27. Hi-Lo’ Adjustment on the MD34-DV-2’s gas valve.

CAUTIONS n Fireplace gas control must be in the “OFF” position and pilot
and main burners extinguished when cleaning appliance with a vacuum.
n Doors and logs can get very hot. Handle only when cool.

General

n Have the fireplace installation inspected yearly, including a visual check of the vent system, the burner and the pilot flame. For your convenience a 1/8″ manifold pressure tap is supplied on the gas valve for a test gauge connection. See Figure 28.
n For Natural Gas this appliance requires a minimum inlet pressure of 5.5″ W.C. and a manifold pressure of 3.5″ W.C.
n For Propane Gas this appliance requires a minimum inlet pressure of 11″ W.C. and a manifold pressure of 10″ W.C.
n Always keep the fireplace area clear and free of combustible materials, as well as gasoline and other flammable vapours and liquids.
n Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

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 burning of protective coatings on new metal.

n Glass must be cleaned periodically to remove any film (which is a normal biproduct of combustion) which may be visible. Film can easily be removed by removing the door, as shown on page 13. Handle the door carefully, and clean it with nonabrasive glass cleaners. One of the most effective products is Kel Kem.

n 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 using normal household products.

n Use a vacuum cleaner or whisk broom to keep the control compartment, burner, and firebox free from dust and lint.

n Logs may be cleaned periodically with a vacuum to remove

soot or easily.
