Mantels

When the unit is installed into a woodburning fireplace, the minimum distance the mantel can be placed above the fireplace is governed by local building codes appli- cable to woodburning fireplaces. Consult local authori- ties having jurisdiction for these clearances. The under- side of the mantel will become warm. Use only finishes which are heat resistant and do not discolor.

RHEDV25 / RHEDV32 / RHEDV42

Certified To

ANSI Z 21.88-2002 / CSA 2.33-2002

Vented Gas Fireplace Heaters

The installation of your Vermont Castings, Majestic Products Fireplace must conform with local codes, or in the absence of local codes, with National Fuel Gas Code, ANSI Z223.1 latest edition, or CSA B149.1 Installation Code. (EXCEPTION: Do not derate this appliance for elevations up to 4,500 ft. (1370mm). Maintain the manifold pressure at 3.5" w.c. for Natural Gas and 10" w.c. for LP gas.)

High Elevations

Input ratings are shown in BTU per hour and are certified without deration for elevations up to 4,500 feet (1,370m) above sea level.

For elevations above 4,500 feet (1,370m) in USA, installations must be in accordance with the current ANSI Z223.1 and/or local codes having jurisdiction.

In Canada, please consult provincial and/or local authorities having jurisdiction for installations at elevations above 4,500 feet (1,370m).

Preparation

Before beginning, remove glass door and logs from unit. Also check to make sure there is no hidden damage to the unit. Take a minute and plan out the gas,venting and electrical route. It is best to start with the gas line first followed by the chimney liner. (Refer to Page 8)

Gas Line Installation

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

The gas pipeline can be brought into the fireplace base from the right side. It is most convenient to install it from the right side into the valve.

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

The gas line connection can be made of either properly tinned 3/8" copper pipe, 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 CSA- B149.1 installation code.

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

The gas control inlet is 3/8" N.P.T. therefore the 1/2" rigid gas line must be reduced to 3/8" N.P.T. Typical installation layout for rigid pipe is shown following. (Fig. 1)

During any pressure testing of the gas line system, when the test pressures are to exceed 1/2 psi (3.5 kpa) the fireplace and its gas valve must not be connected to that system.

At test pressures equal to or less than 1/2 psi, the gas valve of the fireplace may be connected to the gas line, but must be in the closed position.
