life.

Suggested Tools for Installation and Service

The following tools are recommended for installation and
service:

• T-Handle (required in Massachusetts)

Fuel Conversion

The Direct Vent Gas Stove is only for use with the types of gas
indicated on the rating plate. If you need to convert the stove to
use a different type of gas, a conversion kit is supplied with the
appliance.

Initial Break-in

During the initial stages of operation, smoke and odor may occur
depending upon temperatures generated over time. This curing
condition can be alleviated by promoting fresh air circulation
within the immediate vicinity of the appliance. Refer to page 23

5. Installation Requirements

Location
In selecting a location for the stove, consider the following points: 1) Heat distribution 2) Vent termination requirements 3) Gas supply line routing 4) Traffic areas, furniture, draperies, etc.
The stove may be located on or near conventional construction materials, however, proper clearance to combustibles must be maintained in order to provide adequate air circulation around the appliance. Also, it is important to provide adequate access around the stove for servicing and operation.
The clearance and hearth specifications listed in this manual are the minimum requirements for combustible material. A combustible material is anything that can burn (i.e. sheet rock, wall paper, wood, fabrics etc.). These surfaces are not limited to those that are visible and also include materials that may be located behind non-combustibles.
If you are not sure of the combustible nature of a material, consult your local fire officials. Remember, “Fire Resistant” materials are considered combustible: they are difficult to ignite, but will burn. Also, “fire-rated” sheet rock is considered combustible.

RE-INSTALL THE TOP PLATE BEFORE CONNECTING VENT TO THE STOVE.
Vent Restriction
The GF 520 DV is equipped with an Exhaust Restrictor Plate which enables regulation of the exhaust gas flow. The plate prevents overly-strong draft that can cause poor combustion and weak flame picture. Follow the guidelines below and on the following pages to determine the correct restrictor plate setting for your particular installation.
Exhaust Restrictor
The Exhaust Restrictor plate is located on the rear of the firebox. It is adjusted by rotating the dial on the back shroud within a range beginning at the factory-set, fully open position (no restriction) to a fully restricted position. See Figs. 6.2 and 6.3. The Minus (-) and Plus (+) signs on the dial relate to degrees of restriction, from zero to approximately 70%. The three, lettered positions correlate to the termination zones (A,B,C) diagramed in figure 6.2. Use the diagram to determine the degree of restriction and shutter setting that correlates to your vent configuration.
Adjusting Exhaust Restrictor Plate: 1. Use a 1/4″ nut driver to loosen the screw and then use the
pivot tab to set the dial to the position appropriate to your termination zone. See figs. 6.2-6.4, page 11. 2. Re-tighten the screw after adjustment.

10

Approved Horizontal and Vertical Vent Terminations
· ALL VENTING MUST TERMINATE (END) WITHIN ONE OF THE DESIGNATED AREAS.
· SET STOVE EXHAUST RESTRICTOR TO THE POSITION THAT CORRESPONDS TO THE VENT TERMINATION AREA IN THE MATRIX. When termination is exactly on a division line, use the less restrictive position. For example, if termination is 10 feet high and offset 7 feet, restriction should be set at Position B.
· Up to two 45° elbows or one additional 90° elbow is permitted in addition to the first elbow, however, a 5 foot reduction in horizontal length must be made for each additional elbow whether 45° or 90°.

130139 Rev 1 GF 520 DV 12/22
Vertical Vent Termination
This appliance may be vertically vented through a ceiling or to a roof termination using the following guidelines:
The termination should fall within the shaded areas of the
grids depicted in the Vent Matrix, fig. 6.2, page 11.
Maximum Horizontal run is 20 ft. (152 cm) See Fig. 6.2 for
related termination zone limitations.
Minimum Vertical Termination is 6 ft. (183 cm).
Total run, including offsets, must not exceed 30 ft. (9.14m).
Vent Terminus Clearance: In no case shall any discharge
opening on the cap be less than 18 in. (457 mm) horizontally from the roof surface. See fig. 6.6.
Steep roofs, nearby trees, and predominantly windy
conditions can contribute to poor draft and/or promote draft reversal. Increasing the height of the vent may alleviate these conditions.
Use Wall Straps to support an offset pipe run at intervals of
three feet to avoid excessive stress on the offsets.
A firestop is required at every floor. The floor opening
should be framed to 10″ X 10″ inside dimension.
Any venting that is exposed in living space above the first
floor must be enclosed. Always maintain the required 1″ clearance from all sides of the vertical vent system. Insulation in attic space must be retained by an insulation barrier.
Allowable minimum vent run is 1′ vertical with 6″ horizontal.

Any horizontal run of vent must be level or have a
1/4 in. rise for every foot of run toward the termination cap. NEVER ALLOW THE VENTING TO RUN DOWNWARD FROM STOVE TO TERMINATION; A DOWNWARD VENT RUN TRAPS HEAT AND CREATES A FIRE HAZARD.
The horizontal termination cap must maintain a 3″ clearance
to any overhead combustible projections 2 1/2″ or less. It must also maintain 12″ clearance from projections exceeding 2 1/2″.
A direct vent terminal may not be recessed into a wall or

8. Gas Supply Connection
Route the gas supply line to the flex line behind the unit.
Gas installation should be approximately 12″ from the center line on either side of the unit.
The gas supply line should be 3/8″ npt with a 1/2″ diameter
supply, 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. However, Canadian methods vary depending on local code.
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.
All codes require a gas shut-off 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 stove for servicing and maintenance. See fig. 8.1.
A T-HANDLE GAS COCK IS REQUIRED IN MASSACHUSETTS TO COMPLY WITH CODE 248CMR.
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 at all joints.

9. Gas Pressure
Correct gas pressure is essential for efficient and safe operation of the GF 520 DV gas stove. It is important that the correct pressure is established at the time of the installation. Proper gas pressure provides a consistent flow of gas to the appliance and is instrumental in checking for gas leaks.
Pressure Test: Attach a manometer to the appropriate test point on the valve. See fig. 9.1.
The gauge connections are located on the front of the valve. Connections are identified by:
A – for Manifold Pressure (the amount of gas that is coming out of the valve to the burner.)
B – for Inlet or Supply Pressure (the amount of gas coming to the valve.)
ALWAYS TEST PRESSURES WITH VALVE CONTROL KNOB SET ON HIGH.

12. System Check
1. PURGING THE GAS LINE: When lighting the appliance for the first time, it will take a few moments to clear the gas line of air. Once this purge is complete, the appliance will operate as described in the lighting instructions. From a cold start, it may be helpful to let the pilot light burn in mode for 10 – 15 minutes to establish positive draft, before turning the burner on. See the procedure on the inside back cover of this manual. Subsequent burner starts will not require purging the gas line unless the supply line is shut off.
2. PILOT FLAME: You can monitor the pilot flame located behind the burner at the rear of the firebox. The pilot flame should be steady – not lifting or floating. The flame should be blue in color around the pilot hood, with traces of yellow toward the outer edges. Fig. 12.1.
The pilot flame should engulf the top 1/8″ of the thermocouple and thermopile . The pilot flame should project from the pilot hood port toward the burner carryover ports. Adjust the pilot flame using the adjustment screw to the left of the valve regulator. See fig. 12.2.
3. See Flame Appearance / Air Shutter for air shutter settings and adjustments. Note: The more offsets there are in the vent system, the greater the need for an air shutter adjustment.

INITIAL FIRING PROCESS Heat-curing the Stove Paint
This appliance has been painted with the highest quality coating used in the hearth industry. Manufacturers have selected this product because it has been proven durable, colorfast, and beautiful at temperatures up to 1200°F/650°C. Although the paint has been air-dried at the factory, it must be heat-cured in order to maximize its coating properties and durability. This process occurs during initial firing of the appliance and will generate odor and some visible smoke. We recommend you do the following BEFORE operating the appliance for the first time:
1. Ventilate: Open doors and windows and use a fan to circulate fresh air throughout the room.
2. Vacate: The fumes are non-toxic, but can be uncomfortable for babies, small children, pregnant women, elderly, pets, or anyone having breathing difficulties.

Gas Appliance Curing Process
1. After the installer has confirmed proper burner function at all heat levels, the homeowner should operate the appliance at a low setting for several hours, followed by several hours operation at a high setting.
2. Off-gassing by paint and log set ceramic material may leave a white, powdery deposit on the inside surface of the glass panel. This residue must be removed using a nonabrasive hearth gas appliance glass cleaner or warm water to prevent permanent etching of the glass.
DO NOT USE AMMONIA-BASED CLEANERS. DO NOT CLEAN HOT GLASS.
See OPERATION sections, pages 31-32, for detailed, dayto-day operating procedures.

13. Flame Appearance /
Air Shutter Adjustment
The GF 520 DV gas stove is shipped from the factory equipped to burn Natural gas and the air inlet shutter has been set to provide optimal combustion efficiency under a variety of venting configurations. The air shutter may be adjusted, however, to accommodate the conditions of your individual installation and to provide the desired flame picture. Other installation- related variables can also affect the flame picture:
Too large an air setting – the appliance will generate a flame that is blue and transparent, or an “anemic” flame.
Too small an air setting – the appliance will generate very long yellow flames resulting in black soot deposits on the logs, on the inside walls of the appliance, and potentially on the exterior termination cap. Sooting is caused by incomplete combustion in the flames and/ or insufficient combustion air entering the air shutter opening.

CLOSE Restrict oxygen

OPEN Increase oxygen

Figure 13.1. Pull the shutter forward to increase primary air. Push it back to restrict air.
To adjust the air shutter: 1. Loosen the wing nut shown in fig. 13.1. Slide the Air Shutter
Handle forward toward yourself to open the air shutter and back to provide less air. Before making any adjustments, start at the mid-point of the total range of adjustment.
2. Allow the stove to burn for 15-20 minutes on the HIGH setting, observing the flame continuously. If the flame appears weak, slow, or sooty, increase the air shutter opening in 1/16″ – 1/8″ increments until the desired flame picture is achieved. Allow the flames a few minutes to “settle-in” after each adjustment.
3. Tighten the wing nut to secure the shutter at the desired setting.

Figure 13.2. Log Set burner flame picture. 30

14. Operation
Important Notes
1. For the first several hours of operation, it is common to detect some odor as the metal and manufacturing materials cure under heat. This condition is temporary and can be alleviated by allowing plenty of fresh air to circulate through the area.
2. Condensation may develop on the glass upon each lighting of the appliance. This “fog” will disappear as the glass heats.
3. IMPORTANT: It will be necessary to clean the glass after the first few fires. A white powdery residue will be evident which results from the burner media curing. Use a nonabrasive hearth gas appliance glass cleaner and warm water.
IF THE GLASS IS NOT CLEANED, THIS RESIDUE CAN CAUSE THE GLASS TO BECOME PERMANENTLY ETCHED.
DO NOT USE AMMONIA-BASED CLEANERS.
4. Keep the control compartments and area under the appliance free of dust. Always keep the appliance area clear and free from combustible materials, gasoline and other flammable liquids.
5. This appliance can be operated with a continuously burning pilot flame. Exercise caution when using household products containing combustible vapors.
6. CAUTION: DO NOT OPERATE THIS APPLIANCE WITH ANY OF THE GLASS PANELS REMOVED, CRACKED OR BROKEN. REPLACEMENT OF THE GLASS SHOULD BE DONE ONLY BY A LICENSED OR QUALIFIED SERVICE PERSON. USE ONLY REPLACEMENT GLASS PROVIDED BY YOUR AUTHORIZED JØTUL DEALER. NEVER SUBSTITUTE ANY OTHER TYPE OF GLASS.
REMOVE GLASS ONLY FOR ROUTINE MAINTENANCE.
ALWAYS HANDLE GLASS CAREFULLY.
