7.The U-channel located on the top of the unit as well as the nailing flanges on the sides that were mentioned in Step 1, are designed to accommodate noncombustible board (recommended Dura-Rock). They are positioned 1” (25mm) back from the face of the unit. NOTE: The U-channel depth can be adjusted by loosening the hex nut inside the channel.

If marble, tile or any other noncombustible decorative face finish material is desired, a 3” (76mm) wide noncombustible board (recommended Dura-Rock) is to be nailed to the nailing flanges on both sides of the unit. Also, 12” (305mm) of noncombustible board is to be nailed to the front face of the U-chan- nel and the top framing member above the standoff.

Combustible material can then be brought to the outside edges of the noncombustible board installed earlier. Any noncombustible decorative face finish could be brought to the sides and top of the unit and can cover the framing and sheet rock. If a decorative facing is not desired, then the noncombustible boards must be double thickness and brought flush with the face of the unit.

Final Finishing

Noncombustible materials such as brick or tile may be brought to the edges of the face of the appliance.

Always check for gas leaks with a mild soap and water solution applied with a

brush no larger than 1” (25mm). 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 psi.

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 up stream of the control.

When using copper, use only approved fittings. Always provide a union when using black iron pipe so the gas line can be easily disconnected for burner servicing. A union may not be behind a wall. (Fig. 9) See the gas specifications for pressure details and ratings.

Remote ON/OFF Switch

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

supply.

The unit is equipped with an ON/OFF rocker switch at the valve box assembly. If a wall switch is desired, follow these instructions.

1.The valve box is equipped with two knockouts at the top right and left corners. The right knockout is designed to run the wall switch wires to the valve. Use Romex connectors when running wires through the valve box where the knockouts are located.

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

3.Connect the other end of the wire to the gas control valve. (Fig. 10)

General Information Assembling Vent Pipes

SK8 Venting Pipes

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 with local codes and/ or the current National Fuel Gas code ANSI Z223.1/ NFPA 54.

Only venting components manufactured by Vermont Castings, Majestic Products can be used in Direct Vent systems.

NOTE: The joints of the inner pipe (flue pipe) must be taped with 550°F or higher temperature metal adhesive tape that meets the requirements of F.A.R. 25.853(a)

High temperature sealant milpack or stove cement of 550°F or higher could be used instead. The joints of The outer pipe (fresh air pipe) must be taped with

315°F or higher temperature metal adhesive tape or the use of high temperature milpack or stove cement would be applicable. When using the unitized 30°, 45° or 90° elbows, apply 1/4” bead of high temperature, 550°F or higher, sealant (milpack or stove cement) to the joint of the inner pipe (flue pipe) and the straight section as it is impossible to be taped. The outer pipe must be taped with 315°F high temperature metal adhesive tape for proper sealing.

Start by attaching the first vent pipe section to the collar on top of the fireplace. In order to attach the first pipe section, it may be necessary to remove the top shield. Remove four (4) screws securing top shield, install first pipe section and replace top shield.

Install the pipe as shown in Figure 14. When you get a good lock, you will hear the pipe clearly snap together. Once sections are snap-locked in place, it is extremely difficult to get them apart. Make sure the pipe is firmly snapped and locked together as each pipe section is mounted.

When installing elbows, follow the same procedure. The joints of inner and outer elbow must be taped with UL approved high temperature metal adhesive tape for proper sealing. Be sure to always attach straps on upper elbow to a structural framing member.

For vertical installations, continue installing the pipe as required until pipe is installed up through the ceiling. At this point, you must install a firestop spacer.

Horizontal Termination

The vent must rise vertically a minimum of 24” (610mm) off the top of the unit, before the first elbow. The horizontal run may extend up to 20ʼ (6m) and include a vertical rise of up to 40ʼ (12m). (Fig. 15) Horizontal termination must also meet the criteria shown in Figures 12 & 13.

•Approved vent systems must terminate above and including the heavy line in Figure 15.

•Two 45° elbows may be substituted for each single 90° elbow.

•With a rise between 2ʼ - 4ʼ, one (1) 90° or two (2) 45° elbows may be used.

Vertical Termination

A vertical vent system must terminate no less than 12ʼ (3.66m) and no more than 40ʼ (12m) above the appliance flue collar. A 2ʼ (610mm) vertical section must be installed before any offset. A maximum of 20ʼ (6.1m) horizontal and three (3) 90° elbows may be installed with a minimum of 12ʼ (3.66m) vertical section above the flue collar of the unit. Refer to Page 15, Figure 26 for more information.

A vertically terminated vent system must also conform to the following criteria:

•No more than three (3) 90° elbows may be used.

•Two (2) 45° elbows may be substituted for one (1) 90° elbow. No more than six (6) elbows may be used.
