IMPORTANT:

PLEASE REVIEW THE FOLLOWING

CAREFULLY

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 Majestic gas fireplace to give off some odour 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 Majestic fireplace for a least six (6) hours the first time you use it. If optional fan kit has been installed, place fan in the "OFF" position during this time.

This appliance may be installed in an aftermarket permanently located, manufactured (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 an available certified kit is used.

GAS LINE INSTALLATION

When purging gas line one of the glass sides must be removed.

The gas pipeline can be brought in through the rear right side (see Fireplace Specifications) of the appliance as well as the bottom. Knockouts are provided at convenient locations 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, 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 some additional local codes, it is always best to consult your local authority and the CAN/ CGA-B149 (1. or .2) Installation code or for

U.S.A Installations consult the current National Fuel Gas Code, ANSI Z223.1

Always check for gas leaks with a mild soap and water solution. Do not use an open flame for leak 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.

GENERAL VENTING

Your fireplace is approved to be vented either through the side wall, or vertical through the roof.

-Only Majestic venting components specifically approved and labelled for this fireplace may be used.

-Minimum clearances between vent pipes and combustible materials is one (1") inch (25 mm), except where stated otherwise.

-Venting terminals shall not be recessed into a wall or siding.

-Horizontal venting must be installed on a level plane without an inclining or declining slope.

There must not be any obstruction such as bushes, garden sheds, fences, decks or utility buildings within 24" 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 that the vent termination be located observing the minimum clearances as shown on this page.

*Check with local codes or in absence of same with CAN/CGA B149 (.1 or .2) Installation Codes (1991) for Canada or for U.S.A. Installations follow the current National Fuel Gas Code, ANSI Z223.1.

STEP 3

Measure from fireplace collar to face of outside wall (add 2" for vent pipe overlap. Mark pipes and cut to length. It is very important that the two pipes are flush with the outside wall once the fireplace is in its final location. Fig. 13.

STEP 4

Slip 4" and 7" pipes onto respective flue collars. Make sure to fix to the fireplace collar the 4" pipe with three (3) screws before fixing the 7" pipe on the 7" collar. Both pipes must be on a level plane. Fig. 13.

STEP 5

Guide the vent termination 4" collar into the 4" pipe then the 7" collar into the 7" pipe. Do not force the venting into position. If the pipes do not line up with the termination collars, disassemble pipes and reattach to the fireplace collar. (Fig. 13)

STEP 6

Secure fireplace to floor through floor holes and adjustable frame drywall strip (nailing flange) to frame. (See Framing & Finishing Section)

VERTICAL SIDEWALL APPLICATIONS

Vent Starter Kit 7DVSK, plus Transition Elbow 7DVRT90 must be used in Vertical Sidewall installations. The 4" pipe must be centred inside the 7" pipe coming off the 7DVRT90 transition elbow.

Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.

The graph showing the relationship between vertical and horizontal side wall venting will help to determine the various vent lengths allowable. Fig. 19.

Minimum clearance between vent pipes and combustible materials is one (1") inch (25 mm) on top, bottom and sides unless otherwise noted.

When vent termination exits through foundation less than 20" below siding outcrop, the vent pipe must flush up with the siding. A 7DVSS must also be used.

It is always 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 to the face of the outer wall.

Horizontal plane means no vertical rise exists on this portion of the vent assembly.

For some installations, it may be desireable to have some amount of the horizontal vent run immediately after the fireplace. A vertical rise must be used but can be located anywhere in the vent system, to meet the perimeters identified in the venting graph.

The maximum horizontal vent run is 20 feet (6100mm) when the vertical vent rise is 7.5 feet (2286mm). Fig. 14

VERTICAL SIDEWALL APPLICATIONS

The maximum number of 90 degree elbows per side wall installation is four (4), (includes 7DVRT90 off back of unit)

The maximum number of 45 degree elbows permitted per side wall installation is two (2). These elbows can be installed in either the vertical or horizontal run.

The maximum number of elbow degrees in a system is 270º. (This does not include transition elbow from rear vent to vertical vent).

For each 45 degree elbow installed in the horizontal run (while maintaining a constant horizontal plane), the length of the horizontal run MUST be reduced by 18" (457mm). This does not apply if the 45 degree elbows are installed on the vertical part of the vent system.

If a 90 degree elbow is used in the horizontal vent run (level height maintained) the maximum horizontal vent length is reduced by 36 inches. Fig. 18. This does not apply if the 90 degree elbows are used to increase or redirect a vertical rise.

Example: According to the vent chart the maximum horizontal vent length is 20 ft.when the vertical height is 8 ft. from fireplace base height. If one 90 degree elbow is required in the horizontal vent it must be reduced to 17 ft.
