Installations follow local codes and/ or the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

FOR SAFE INSTALLATION AND OPERATION, NOTE THE FOLLOWING:

1.This fireplace gives off high temperatures and should be located out of high traffic areas and away from furniture and draperies.

2.Children and adults should be alerted to the hazards of the high surface temperatures of this fireplace and should stay away to avoid burns or ignition of clothing.

3.Children should be carefully supervised when in the same room as your fireplace.

4.Under no circumstances should this fireplace be modified. Parts removed for servicing should be replaced prior to operating this fireplace again.

5.Installation and any repairs to this fireplace must be performed by a qualified installer, service agency or gas supplier. A professional service person should be contacted to inspect this fireplace annually. Make it a practice to have all of your gas fireplaces checked annually. More frequent cleaning may be required due to excess lint and dust from carpeting, bedding material, etc.

6.Control compartments, burners and air passages in this fireplace should be kept clean and free of dust and lint. Make sure the gas valve and pilot light are turned off before you attempt to clean this fireplace.

7.The venting system (chimney) of this fireplace should be checked at least once a year and if needed your venting system should be cleaned.

8.Keep the area around your fireplace clear of combustible materials, gasoline and other flammable vapor and liquids. This fireplace should not be used as a drying rack for clothing, nor should Christmas stockings or decorations be hung in the area of it.

9.Under no circumstances should any solid fuels (wood, coal, paper or cardboard etc.) be used in this fireplace.

10.The flow of combustion and ventilation air must not be obstructed in any way.

11.When fireplace is installed directly on carpeting, vinyl tile or any combustible material other than wood, this fireplace must be installed on a metal or wood panel extending the full width and depth of the fireplace.

12.This fireplace requires adequate ventilation and combustion air to operate properly.

13.This fireplace must not be connected to a chimney flue serving a separate solid fuel burning fireplace.

14.When the fireplace is not in use it is recommended that the gas valve be left in the “OFF” position.

Proposition 65 Warning: Fuels used in gas, woodburning or oil fired appliances, and the products of combustion of such fuels, contain chemicals known to the State of California to cause cancer, birth defects and other reproductive harm.

California Health & Safety Code Sec. 25249.6

This appliance may be installed in an aftermarket permanently located, manufactured home or mobile home, where not prohibited by local codes.

This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases, unless a certified kit is used.

The DVRT36RMH has been approved for mobile home installations.

IMPORTANT:

PLEASE REVIEW THE FOLLOWING CAREFULLY

Remove any plastic from trim parts before turning the fireplace “ON”.

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.

It is not unusual for your Vermont Castings, Majestic Products gas fireplace to give off some odor the first time it is burned. This is due to the curing of the paint and any undetected oil from the manufacturing process.

Please ensure that your room is well ventilated - open all windows.

It is recommended that you burn your fireplace for at least ten (10) hours the first time you use it. If the optional fan kit has been installed, place the fan switch in the “OFF” position during this time.

Gas Line Installation		Remote ON/ OFF Switch Installation

When purging the gas lines, the front glass must be removed.

The gas pipeline can be brought in through the side of the fireplace as well as the bottom. Knockouts are provided on the bottom behind the valve to allow for the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in from the rear right side of the valve as this allows fan installation or removal without disconnecting the gas line.

The gas line connection can be made with properly tinned 3/8” copper tubing, 3/8” rigid pipe or an approved flex connector. Since some municipalities have additional local codes, it is always best to consult your local authority and the CSA-B149.1 installation codes.

For USA installations consult the current National Fuel Gas Code, ANSI Z223.1/NFPA 54.

Fig. 6 Typical gas supply installation.

Always check for gas leaks with a mild soap and water solution applied with a brush no larger than 1” (25 mm). Never apply soap and water solution with a spray bottle. Do not use an open flame for leak testing.

The fireplace valve must not be subjected to any test pressures exceeding 1/2 p.s.i. Isolate or disconnect this or any other gas appliance control from the gas line when pressure testing.

The gas control is equipped with a captured screw type pressure test point; therefore, it is not necessary to provide a 1/8” test point upstream of the control.

When using copper or flex connector use only approved fittings. Always provide a union when using black iron pipe so that the gas line can be easily disconnected for burner or fan servicing. (Fig. 6) See the gas specifications for pressure details and ratings.

Do not wire the remote ON/OFF wall switch for this gas appliance into a 120 V power supply.

1.Thread the wiring through the electrical knockout located on either side of the unit. Take care not to cut the wire or insulation on metal edges. Ensure the wire is secured and protected from possible damage. Run one end to the gas control valve and the other end to the conveniently located wall switch.

2.Attach the wire to the ON/ OFF switch and install the switch into the receptacle box. Attach the cover plate to the switch.

3.Connect the wire to the gas control valve. (Fig. 7)

It is strongly suggested that a licensed electrician perform the wiring of the EB-1 Electrical Junction Box.

Ensure that the power to the supply line has been disconnected before commencing this procedure.

The EB-1 Electrical junction box is fitted with this model to provide for easy installation of an optional fan kit.

To connect the EB-1 box to the house electrical supply follow the steps below:

1.Unscrew the retaining screw from the EB-1 base plate (Fig. 9), and remove the EB-1 assembly from the fireplace.

2.Remove the front cover of the EB-1 box.

3Remove the plug socket assembly from the EB-1 box.

4.Feed the supply line in from the outside through the cable clamp. (Fig. 9)

5.Connect black wire of the power supply line to the brass screw (polarized) of the socket assembly.

6.Connect the white wire of the power line to the chrome screw of the socket assembly.

7.Connect the ground wire of the supply line to the green screw of the socket assembly.

8.Refit the socket assembly back into the electrical box and replace the cover plate. Secure the cable with the clamp on the outside of the unit to prevent strain on the connections.

General Information for Connecting Vent Pipes

Crimped End Pipes

Before joining elbows and pipes, apply a bead of high temperature sealant to the crimped end of the elbow or pipe.

Join the pipes using a 2” (51mm) overlap and secure the joints with three (3) sheet metal screws. (Fig. 16) Wipe off excess sealant.

Canadian Installations:

The venting system must be installed in accordance with the current CSA-B149.1 installation code.

USA Installations:

The venting system must conform to local codes and/ or the current National Fuel Code ANSI Z223.1/NFPA 54.

Twist-lock Pipes

When using Vermont Castings, Majestic Products 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 collars on the fireplace and the sliding joint 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. (Fig. 17)

To make it easier to assemble the joints we suggest putting a lubricant (Vaseline or similar) on the male end of the twist-lock pipe prior to assembly.

How to Use the Vent Graph

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 below, 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 fireplace is 11’ (3.4m), the horizontal run to the face of the outer wall must not exceed 14’ (4.3m).

Example B:

If the vertical dimension from the floor of the unit is 7’ (2.14m), the horizontal run to the face of the outer wall must not exceed 8¹⁄’ (2.6m).

Rear Wall Vent Installation

Step 1

Locate and cut the vent opening in the wall.

For combustible walls, first frame in opening. (Fig. 20)

Combustible Walls: Cut a 10³⁄ ” H x 9³⁄ ” W (265 x 240mm) hole through the exterior wall and frame as shown.

Noncombustible Walls: Hole opening should be 7¹⁄ ” (190mm) in diameter.

Zero clearance sleeve is required only for combustible walls.

Step 2

Measure wall thickness and cut zero clearance sleeve parts to proper length (maximum 12” / 305mm). Assemble sleeve to its maximum opening (10³⁄ ” x 9³⁄ ”)(265 x 240mm), and attach to firestop with #8 sheet metal screws (supplied). Install firestop assembly. (Fig. 21)

Step 3

Measure the horizontal length requirement for the venting including a 2” (51mm) overlap; i.e., from the elbow to the outside wall face plus 2” (51mm).

(Fig. 19)

Step 4

Install the 4” (102mm) vent to the appliance collar and secure with 3 sheet metal screws. Install the 7” (175mm) vent pipe to the appliance collar and secure with 3 sheet metal screws. If a 45° elbow is being

used, attach the elbow to the appliance with sealant in the same manner then attach the venting to the elbow. It is not necessary to seal the 45° elbow to the starter pipe or termination in the straight out and 45° installation in Figure 19.

It is critical that there is no downward slope away from the appliance when connecting the vent or elbow.

Step 5

Guide the venting through the vent hole as you place the appliance in its installed position. Guide the 4” (102mm) and 7” (175mm) collars of the vent termination into the outer ends of the venting. Do not force the termination. If the vent pipes do not align with the termination, remove and realign the venting at the appliance flue collars. (Fig. 22) Attach the termination to the wall as outlined in the instruction sheet supplied with the termination.
