IMPORTANT PRE-INSTALLATION AND FIREPLACE SAFETY INFORMATION

To determine the safest and most efficient location for your Vent Free Fireplace, you must take into consideration the following guidelines.

1. This appliance operates as an unvented room heater certified under ANSI Z21.11.2a when fitted to a masonry or factory built fireplace with the flue damper open or closed. It may also be installed in approved vent free fireplace. If installing in an approved vent free firebox, refer to their instruction guide for proper installation. Solid fuels shall not be burned in a fireplace where an unvented room heater is installed.

2. Do not use a natural gas set for propane or a propane set for natural gas. If the gas type is not correct. DO NOT INSTALL. Contact your dealer for immediate assistance. Any change to this heater or its controls can be dangerous.

3. Gas log sets must be installed by personnel qualified for installing gas appliances.

4. The location must allow for proper clearances for accessibility of servicing and proper operation (see section on Fireplace Clearances – page 4).

5. Consider a location where heat output would not be affected by drafts, air conditioning ducts, windows or doors. Do not allow fans to blow directly into the fireplace, avoid any drafts that alter burner flame patterns.

6. Inspect area surrounding the location chosen for the fireplace for possible air drafts that may affect the flames and possibly cause sooting. Air drafts may be caused by a ceiling fan near the fireplace, a hot furnace or an open door.

7. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies. Young children should be carefully supervised when they are in the same room with the appliance. It is recommended that adults be present when this gas appliance is operating. It is recommended that this unit is not left burning when unattended or while anyone is sleeping.

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

9. Install in an area providing adequate combustion and ventilation air (see section on adequate combustion and ventilation air requirements – page 2).

10. Do not install in a building that is of unusually tight construction. Unusually tight construction is defined as construction where:
    a. Walls and ceiling exposed to the outside atmosphere have a continuous wall vapor retarder with a rating of 1 perm or less with openings gasketed or sealed, and
    b. Weather stripping has been added on openable windows and doors, and
    c. Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetration for plumbing, electrical and gas lines and at other openings.

11. Do not install this heater in bedrooms, bathrooms or recreational vehicles.

12. This appliance may be installed in an aftermarket manufactured (mobile) home, where not prohibited by state or local codes.

13. Maintain adequate clearances around air openings.

14. When glass fireplace doors are used, always operate gas log set with the doors fully open to allow for proper combustion air and to keep control valves from overheating.

15. Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids. Do not allow clothing or flammable materials on or near the fireplace. The flame in this appliance is not isolated from the air space it heats and it will ignite flammable vapors, dust particles or other combustible materials that come in contact with it which can result in an explosion or fire.

PREINSTALLATION REUIREMENTS

COMBUSTION AND VENTILATION AIR REQUIREMENT WORKSHEET
WARNING: IF THE AREA IN WHICH THE HEATER MAY BE OPERATED IS SMALLER THAN THAT DEFINED AS UNCONFINED SPACE OR IF THE BUILDING IS OF UNUSUALLY TIGHT CONSTRUCTION, PROVIDE ADEQUATE COMBUSTION AND VENTILATION AIR BY ONE OF THE METHODS DESCRIBED IN THE NATIONAL FUEL GAS CODE, ANSI Z223.1 SECTION 5.3 OR APPLICABLE LOCAL CODES.
This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.
The following formula can be used to determine the maximum BTU rating per the definition of unconfined space:
STEP ONE: DETERMINE THE VOLUME OF SPACE IN CUBIC FEET.
LENGTH X WIDTH X HEIGHT = ____ cu. Ft.
(Include adjoining rooms with doorless passageways or ventilation grills between rooms.)
Example: 24’ (L) X 16’ (W) X 8’ (H) = 3,072. cu. Ft.
STEP TWO: MULTIPLY THE VOLUME OF SPACE BY 20 BTU/Hr. TO DETERMINE THE MAXIMUM BTU/Hr.
THE SPACE CAN SUPPORT.
Example: 3,072 cu. Ft. X 20 BTU/Hr. = 61,440 BTU/Hr.
(Maximum BTU/Hr. the room can support)
STEP THREE: ADD THE BTU/Hr. OF ALL THE FUEL BURNING APPLIANCES IN THE SPACE.
VENT FREE HEATERBTU/Hr.
GAS APPLIANCE #1 BTU/Hr.
GAS APPLIANCE #2 _____BTU/Hr.
Example: VENT FREE HEATER 26,000 BTU/Hr.
GAS APPLIANCE #1 35,000 BTU/Hr.
TOTAL 61,000 BTU/Hr.
NOTE: DO NOT INCLUDE DIRECT-VENT GAS APPLIANCES. DIRECT VENT IS SEALED COMBUSTION AND DRAWS COMBUSTION AIR FROM THE OUTDOORS.
THE SPACE IN THE ABOVE EXAMPLE IS AN UNCONFINED SPACE BECAUSE THE 61,000 BTU’S AN HOUR USAGE IS LESS THATN THE 61,440 BTU’S AN HOUR AVAILABLE. IF THE TOTAL BTU’S AN HOUR USAGE IS GREATER THAN 61,440 BTU’S AN HOUR THEN THE SPACE WOULD BE A CONFINED SPACE AND ADDITIONAL AIR MUST BE PROVIDED.
The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 BTU per hour (4.8 m per kw) of the aggregate input rating of all appliances installed in that space and unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 BTU per hour (4.8 m 3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors, are considered a part of the unconfined space.

FIREPLACE DIMENSIONS AND CLEARANCES
Refer to the following charts to determine the proper size set for your fireplace. MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS AND MANTLE CLEARANCES
IMPORTANT: To insure a safe installation into a masonry or factory built fireplace, the following instructions must be carefully observed. If installing in a pre-manufactured fireplace follow the clearance requirements accompanying that fireplace.
Refer to Fig. 1 for the following dimensions:
A. Minimum left and right clearance to combustible walls = 15”.
B. Minimum clearance to combustible ceiling = 42”.
C. Minimum left and right side clearances to mantle = 6”. Note: Clearances to Combustible Materials and Mantle Clearances are in place to provide adequate spacing to prevent a fireplace mantle or facing from catching fire. In most cases they should also be adequate to prevent any discoloration or warping due to heat. However, each Gas Log installation will present unique circumstances creating many variables beyond the control of the Gas Log Manufacturer, including paint or finish composition, previous heat exposure, quality of construction, air flow patterns etc. Because of these variables we cannot guarantee that heat warping or discoloration will never occur. The possibility of heat damage exists whether burning wood or gas logs. IMPORTANT: Woodwork such as mantles andother combustible material must be installed as tested per Fig 2 or Fig 3. Heat resistant materialare materials such as gypsum board, sheetrock, slate, tile marble etc. If the mantle and wall are both non-combustible, mantle clearances are noapplicable. NOTE: A hood (canopy) as shown in Fig 3 is used to deflect heat away from the fireplace face and mantle, reducing the chances of heat damage or discoloration. If using a hood, it mustproject a minimum of 4” from the face of the firebox. Contact your dealer to purchase a fireplace hood.

PREINSTALLATION CHECKLIST

INSTALLER: Please leave these instructions with the homeowner.
HOMEOWNER: Please retain these instructions for future reference.
State or local codes may only allow operation of this unit in a vented application. Check your state and local codes.

The installation must conform with state and local codes or, in absence of local codes, to the National Fuel Gas Code, ANSI Z223.1

FIREPLACE PREPARATION

IMPORTANT: Before installing in a solid fuel-burning fireplace, the chimney flue and firebox must be cleaned of soot, creosote, ashes, and loose paint by a qualified chimney cleaner.

1. Turn the gas supply to OFF.
2. Turn OFF all electrical power to blower (if applicable) before installing, servicing, or removing.
3. Clean the fireplace floor, walls, and chimney (if used) of any ashes, soot creosote, obstruction. This will minimize any smell from the fireplace. We recommend cleaning by a chimney sweep.
4. Any outside air ducts and/or ash dumps in the fireplace must be permanently closed at the time of appliance installation.
5. A mesh fireplace screen must be in place when the appliance is operating unless other provision for combustion air are provided, the screen shall have an opening(s) for introduction of combustion air.
   This unit complies with 527 CMR 30.00 vent free appliance requirements for Massachusetts.

INSTALLATION

NOTE: Before you proceed, make sure your gas supply is OFF!
Check Gas Type: The gas supply must be the same as stated on the heater’s rating plate. If the gas supply is different, DO NOT INSTALL the heater. Contact your dealer for the correct model.
IMPORTANT: This appliance cannot be used with or converted to a gas other than the type for which it was equipped at the factory.
WARNING: OPERATION OF THIS APPLIANCE ON GASES FOR WHICH IT IS NOT EQUIPPED MAY LEAD TO CARBON MONOXIDE POISONING.
This product must be installed by a licensed plumber or gasfitter when installed within the Commonwealth of Massachusetts.
WARNING: CONNECTING DIRECTLY TO AN UN-REGULATED L.P. TANK CAN CAUSE AN EXPLOSION.

GAS CONNECTION

WARNING: ANY MODIFICATION TO THIS UNVENTED GAS HEATER OR ITS CONTROLS CAN BE  DANGEROUS. IMPROPER INSTALLATION OR USE OF THE HEATER CAN CAUSE SERIOUSINJURY OR DEATH FROM FIRE, BURNS, EXPLOSION OR CARBON MONOXIDE POISONING.

IMPORTANT STEPS TO FOLLOW WHEN MAKING THE GAS LINE CONNECTION

1. Consult your gas supplier for proper gas pipe sizing. Normally up to 50’ of ½” inside diameter (ID) gas pipe will supply adequate volume for all vent free units.
2. The incoming gas line may be routed into the fireplace either from the left or right side.
3. Include a manual shutoff valve in the gas supply line so the appliance may be disconnected for servicing.
4. Center the burner system from side to side in the firebox. In a vented firebox, if the damper is used, the burner assembly should be located directly under the damper.
5. Use the 3/8” flex connector (provided in the accessory kit) to connect the gas supply line to the regulator on the burner assembly.
6. Always use an external regulator for all L.P. appliances to reduce the supply tank pressure to a maximum of 13” W.C. This is in addition to the regulator fitted to the heater.
7. Test all connections after turning gas supply on for leaks using a soap and water solution. DO NOT USE AN OPEN FLAME FOR LEAK TESTING.
8.  It is most convenient to light the pilot and check the operation of the main burner with the logsnot in place. After carefully checking the gas supply line for leaks and correcting any found, refer to the “LIGHTING INSTRUCTIONS” section to test the burner assembly.

WARNING: DO NOT USE A BLOWER INSERT, HEAT EXCHANGER INSERT OR OTHER ACCESSORY NOT APPROVED FOR USE WITH THIS HEATER.

GAS PRESSURE CHECK

NOTE: The appliance and the appliance main gas valve must be disconnected from the gas supply system during any pressure testing of that system at test pressures in excess of 0.5 psig (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing its equipment shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 0.5 psig (3.5 kPa).

1. The gas valve controls the gas pressure, which can be checked at the pressure test point (1/8” NPT plug) located on the side of the valve (see schematic below).
2. The pressure should be checked with the heater burner and the control set to high (HI).
3. The pressure is preset and locked to avoid tampering. If the pressure is not as specified in “BTU Rating and Pressure Requirements” (pg. 3), contact your dealer.
4.  Replace the test plug after measuring gas pressure. Check for gas leaks.
   IMPORTANT: Do not use the appliance if any part has been submerged under water. Immediately call a qualified technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

NOTE: A periodic visual check of the pilot flames (Figure 11) and main burner flames (Figure 12) should be made. The pilot flame should always be present when the appliance is in operation. See illustrations below.

WARNING: TAMPERING WITH THE ODS PILOT WILL VOID THE MANUFACTURER’S WARRANTY.

OPERATION
TO TURN OFF GAS TO APPLIANCE

TEMPORARY SHUTDOWN PROCEDURE:| To turn off main burner only, depress the knob and turn it clockwise as far as it will go. Do not force.
---|---
COMPLETE SHUT-DOWN PROCEDURE:| Turn off all electrical power in firebox. Turn gas control knob clockwise to the “OFF” position.

Controlling Heat Output

• The heat output can be controlled by adjusting thevent free burner control knob.

• Another way to regulate the heat output is to open the fireplace damper.
  If you want:
  a. more heat radiated into the room – Keep the damper completely closed
  b. less heat radiated into the room – open the fireplace damper to varying degrees.
  Important Safeguards
  

  1. To avoid personal injury, do not touch hot surfaces when the appliance is operating. Touch only the piezo ignitor and control knob.
     Hot Surfaces
     a. Grate
     b. Burner
     c. Logs
     d. Surfaces above the opening of the fireplace

  2. Although your gas logs are very realistic in appearance, it is not a real wood-burning fireplace and must not be used for burning any material.

• To avoid irreparable damage to the appliance or personal injury, matches, paper, garbage, or any other material must not be placed or thrown on top of the logs or into the flames.
  Close supervision is necessary when the appliance is being operated near children.
  Avoid any drafts that alter burner patterns. Do not allow fans to blow directly into the fireplace. Ceiling fans may create drafts that alter burner flame patterns. Sooting and improper burning will occur.

Cleaning And Servicing
Installation and repair should be done by a qualified service person. The appliance should be inspected before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding, and material, etc. It is imperative that control components, burners and circulating air passageways of the appliance be kept clean.

• If the flames show any unusual shapes or behavior, or the burners fail to ignite properly, then the burner holes may require cleaning.

WARNING: TURN OFF VENT FREE BURNER SYSTEM AND ALLOW TO COOL BEFORE CLEANING OR SERVICING.
MONTHLY CLEANING

1. If removing logs, when reinstalling, refer to “Log Assembly Diagram” for correct log placement.
2. Do not use cleaning fluids to clean logs or any part of the heater.
3. Brush logs with a soft bristle brush or vacuum with brush attachment.
4. Vacuum loose particles and dust from the front and rear burner ports, gas control, piezo cover, and grate.
5. Inspect and clean ODS pilot for operation and accumulation of lint at air intake holes.
6. Verify flame pattern and log placement for proper operation.
7. Verify smooth and responsive ignition of main burner and rear burner. Refer to page for proper  pictorial sketch of proper operation.
