Safety Information

Due to the high operating temperatures this appliance should be located out of traffic and away from furniture, draperies, etc. Maintain proper clearance to combustible mantels and fireplace trim.

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

Young children should be supervised while they are in the same room as the Acadia gas fireplace.

Surveiller les enfants. Garder les vetements, les meubles, l’essence ou autres liquides a vapeur inflammables loin de l’appareil.

Clothing or other flammable materials should not be placed ON or NEAR the Acadia gas fireplace.

Never allow any to use the fireplace if they are unfamiliar with its operation.

NEVER store or use gasoline or any other flammable vapors or liquids in the vicinity of the Acadia gas fireplace.

Never burn any solid materials (wood, cardboard, paper, coal, etc.) in this gas fireplace. Use with natural gas or propane fuel ONLY.

Any safety screen, glass or guard removed for servicing the appliance must be replaced prior to operating the appliance.

Do not slam or strike the glass panel.

Were gloves and safety glases while performing maintenance procedures.

Electrical Hazard

Be aware of electrical wiring locations when cutting holes in walls and ceilings for termination.

The optional Acadia Blower (154960) must be electrically grounded in accordance with local codes or, in the absence of local codes, with the current ANSI/NFPA 70, National Electrical Code or CSA C22.1-CanadianElectrical Code.

The Acadia Blower is supplied with a three-prong(grounding) plug for protection against shock hazard and should be plugged directly into a properly groundedthree-prongreceptacle. DO NOT CUT OR REMOVE THE GROUNDING PRONG FROM THE PLUG.

Always disconect the power supply when performing routine service on the fireplace.

Installation

Requirements

The GZ 550 DV Acadia Gas Fireplace and its vent system must be installed within a totally enclosed structure. The fireplace must be connected to the specified vent and termination cap outside the building. Do not vent into another room or inside any part of a building.

The approved vent configurations described herein are derived from extensive testing under controlled laboratory conditions. Gas appliance performance can be negatively affected by variables present in the installation environment, i.e: strong prevailing winds, steep roofs, nearby trees, snow accumulation, etc. These conditions should be taken into consideration by the installer and home owner. In such instances, system performance can often be improved by an increase in the vent height or installation of a high wind termination cap.

Placement and Framing

The combustible framing members of the fireplace enclosure may be placed in direct contact with the fireplace cabinet as specified in the illustrations on the following pages. Use the standoffs integrated into the sides and top of the front opening to locate a combustible header and side framing members as shown in the illustrations. See Fig. 1.

Electrical Power: If the optional Blower (#154967) will be used, be sure to include provision for a properly grounded, 120 volt house current outlet at the fireplace structure.

Parallel Installation

Although it is possible to place combustible framing members in direct contact with the rear surface of the cabinet, the fireplace must be located forward of the back wall with adequate clearance to accommodate the vent adaptor and subsequent lengths of vent pipe. Consideration must also be given to maintaining a minimum 1 inch (25 mm) clearance between a vertical vent pipe and any combustible materials to the rear of the unit. See Figs. 2, 3, and 4.

Corner Installation

A corner installation will require that the Vent Adaptor be installed in a top exit position. Horizontal terminations will then require use of a 90° elbow. Figs. 5 and 5a show rear termination with 5/8 Simpson Dura-VentWall Thimble #1247.

Hearth Protection

The GZ550 Acadia is approved for installation without hearth protection. Combustible materials may be used on the floor directly under and in front of the fireplace. NOTE: The floor surface under the unit must be level with or higher than the surface in front of the unit in order for the fireplace Controls Door to open properly.

Facing and Clearance Requirements

The following clearance and hearth specifications are the minimum requirements for the GZ550 Acadia gas fireplace. Measure clearances from the steel fireplace cabinet - not the cast iron surround panels. See Figures 6 - 8.

A combustible surface is anything that can burn (i.e. sheet rock, wallpaper, wood, fabrics etc.). These surfaces are not limited to those that are visible and also include materials that are behind non-combus-tibles.

If you are not sure of the combustible nature of a material, consult your local fire officials. “Fire Resistant” materials are considered combustible - they are difficult to ignite, but will burn. “Firerated” sheet rock is also considered combustible.

Maintain the proper clearances to the appliance to allow adequate flow of ventilation air around the fireplace.

Vent restriction is accomplished by sliding two restrictor panels over the combustion air intake ports located at the back of the firebox, just below the logset base. See Fig 19. The panel levers will be most accessible with removal of the logset.

The panels are set in a fully open position at the factory. Push each lever toward the center of the firebox to increase restriction in one inch increments, e.g: 1 inch travel = 1/3 closed position.

Use the Vent Window diagrams in Figs. 12-13as a starting point to determine the best restriction setting. The ideal restrictor setting for a particular vent system will vary depending on the specific installation characteristics. Once the fireplace is operating, further restrictor adjustment may be necessary to obtain the best performance. See the Operation chapter of this manual for further information.

Fireplace Installation

Optional Blower

Install the optional Blower (154967) before installing the gas supply line. The 125 CFM heat-activatedfan unit will be located in the bottom rear of the fireplace cabinet.

Power Requirement

The blower must be electrically grounded in accordance with local codes or, in the absence of local codes, with the current NFPA 70National Electrical Code or CSA C22.1-CanadianCode.

A three-prong(grounding) power supply plug is included for protection against shock hazard and should be plugged directly into a properly groundedthree-prongreceptacle.DO NOT CUT OR REMOVE

THE GROUNDING PRONG FROM THE PLUG.

Blower Function

The blower is controlled by a heat activated switch (snapstat) that will ONLY function if the blower control switch is either in the HI or LOW setting. Once the unit has been operating for a short time and the firebox heats, the blower will start on either the HI or LOW speed.

Conversely, once the unit is off the blower will continue to operate until the snapstat cools and turns the blower off.

If the blower is not needed, place the blower control switch in the OFF position and the snapstat will not function.

CAUTION: Always unplug the Blower when performing any routine service to the Acadia gas fireplace.

Installation

1.Insert a rubber grommet at each corner of the Base Plate as shown in Fig. 20.

2.Engage the Blower unit base with the four studs at the rear of the fireplace cabinet floor. See Fig. 21.

3.Using the M6 nuts and 10 mm socket, attach the Control Switch / Snapstat Bracket to the two studs protruding from the firebox floor. See Fig. 22. Be sure that the snapstat disc firmly contacts the bracket surface.

4.Run the power cord through the opening in the side of the cabinet nearest the receptacle. Gather slack cord into the side cavity, away from the plumbing and other wiring.

Connect the Gas Supply

Gas Supply Requirements

ALL INSTALLATIONS MUST COMPLY WITH LOCAL CODE OR IN THE ABSENCE OF LOCAL CODE, MUST COMPLY WITH THE MOST RECENT EDITION OF THE NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR CAN-B149.

Shutoff Valve

All codes require a gas shutoff valve (gas cock) and union to be installed in the supply line and in the same room as the appliance. This allows for the disconnection of the fireplace for servicing and maintenance. See Fig. 25.

A T-handlegas shutoff valve is required in Massachusetts in compliance with Code 248CMR.

The fireplace and gas control valve must be disconnected from the gas supply piping during any pressure testing of the system at test pressures in excess of 1/2 psig. For pressures lower than 1/2 psig, isolate the gas supply by closing the manual shutoff valve.

Control Valve Connection

The gas supply line connection is made to the left side of the valve. The gas supply line should be a minimum 3/8" diameter, or the appropriate size to provide sufficient gas pressure to the valve regardless of the input setting.

The use of flexible gas appliance connectors is acceptable in many areas in the U.S. In Canada, methods vary depending on local code. If local codes permit, use flexible gas line for ease of installation and service. For those locales where flexible gas lines are not permitted, use the 3/8” iron fitting to make the connection at the left side of the Control Valve. See Figures 25 and 26.

Secure all joints tightly using appropriate tools and sealing compounds (for propane units, be sure to use compounds that are propane resistant). Turn on gas supply and test for gas leaks using a soapy water solution. Never use an open flame to check for leaks.

Leak test:

Mix a 50-50solution of water and dish soap.

Light appliancesee lighting instructions on page 23 of this manual or on the fireplace’s rating plate.

Brush or spray all joints and connections with the soapy water solution.

If bubbles appear at any connection or seam or a gas odor is detected, immediately turn gas control knob to the OFF position.

Tighten or reconnect the leaking joint and retest for any gas leaks.

Figure 25. Gas supply line fittings.

Gas Pressure

Proper gas pressure provides a consistent flow of gas to the appliance and is instrumental in checking for gas leaks. The gas control valve on the fireplace is equipped with pressure test points for gauge connections. The gauge connections are located on the front of the valve under the On/Off/ Pilot knob. Gauge connections are identified by:

IN/E forinlet or supply pressure (the amount of gas coming to the valve.)

OUT/A formanifold pressure (the amount of gas that is coming out of the valve to the burner.)

E A

Figure 26. Pressure test point as located on the front of the valve.

Insufficient gas pressure:

Small pilot flame which can result in insufficient millivolts.

Little variation in flame picture between HI and LO settings.

Insufficient gas to support more than one appliance causing nuisance outages or gas surges.

Excessive gas pressure:

Permanent damage to valve causing complete appliance shut down.

Too large a pilot flame resulting in overheating of the power generator and consequent shut down.

Sooting due to impingement and/or incorrect fuel to air mix.

High Altitude Adjustment

Installations located at altitudes from 2000 - 4500 ft. (610 M - 1370 M), require compensation for the thinner air (less volume of air per cubic foot). Higher altitudes affect the atmospheric pressure and heat value of gaseous fuels. The lower oxygen content in the air and the lower gas viscosity require the use of a different orifice to achieve efficient, clean combustion at the burner tube.

For high altitude installations consult the local gas distributor or the authority having jurisdiction for proper rating methods. If the installer must convert the unit to adjust for varying altitudes, use Jøtul High Altitude Kit (#137403).

In the U.S: THE DERATING KIT MUST BE INSTALLED BY AN AUTHORIZED SERVICE TECHNICIAN IN ACCORDANCE WITH THE MANUFACTURER’S INSTRUCTIONS AND ALL CODES AND REQUIREMENTS OF THE AUTHORITY HAVING JURISDICTION. THE INFORMATION STICKER MUST BE COMPLETED BY THE INSTALLER AND APPLIED TO THE APPLIANCE AT THE TIME OF THE CONVERSION. THE QUALIFIED SERVICE AGENCY PERFORMING THIS WORK ASSUMES RESPONSIBILITY FOR THIS DERATING.

In Canada: This unit has been tested for installation at high altitudes in accordance with Canadian test standardCAN/CGA-2.17.THE DERATING SHALL BE CARRIED OUT IN ACCORDANCE WITH THE REQUIREMENTS OF THE PROVINCIAL AUTHORITIES HAVING JURISDICTION AND IN ACCORDANCE WITH THE REQUIREMENTS OF THECAN1-B-149.1AND .2 INSTALLATION CODE.

Derating Procedure

1.Follow Steps 1-4of the Fuel Conversion procedure outlined on page 14.
