PRODUCT IDENTIFICATION

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one(1) ounce (30ml) of water for every 1,000 BTUs (.3KW’s)of gas input per hour. Unvented room heaters are recommended as supplemental heaters (a room). Rather than a primary heat source (an entire house). In most supplemental heat applications, the water vapor does not create a problem. In most applications, the water vapor enhances the low- humidity atmosphere experienced during cold weather. The following steps will help ensure that water vapor does not become a problem.

1. Be sure the heater is sized properly for the application, including ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidifier may be used to help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat source.

AIR FOR COMBUSTION AND VENTILATION

WARNING: This fireplace shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Read the following instructions to ensure proper fresh air for this and other fuel-burning appliances in your home.

PROVIDING ADEQUATE VENTILATION
The following are excerpts from the National Fuel Gas Code, NFPA 54/ANSI Z223.1. Section 5.3, Air for Combustion and Ventilation. All spaces in homes fall into one of the three following ventilation classifications:

1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space The information on pages 5 through 6 will help you classify your space and provide adequate ventilation.

Confined and Unconfined Space

• The National Fuel Gas Code, ANSI Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space.
• An unconfining space is defined as a space whose volume is not less than 50 cubic feet per 1, 000 Btu per hour (4.8 m3 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.
• This fireplace shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.
• Adjoining rooms communicate only if there are doorless passageways or ventilation grills between them.

Unusually Tight Construction

• The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation.
• However, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is defined as construction where:

• a) walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm ( 6×10-11kg per parsec- m2) 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 penetrations for plumbing, electrical, and gas lines, and at other openings.
  • If your home meets all of the three criteria above, you must provide additional fresh air. See Ventilation Air From Inside Building, page 6.
  • If your home does not meet all of the three criteria above, proceed to Determine Fresh-Air Flow For Heater Location, page 6.

AIR FOR COMBUSTION AND VENTILATION

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

• Determining if You Have a Confined or Unconfined Space
• Use this worksheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install the heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

1. Determine the volume of the space (length×width×height). Length×Width×Height= cu. ft. (volume of space)
   • Example: Space size 20ft. (length)×16ft. ( width)×8ft. (ceiling height)=2560 cu. ft. (volume of space)
   • If additional ventilation to the adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.
2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support. (volume of space)÷50 cu. ft.=(Maximum Btu/Hr the space can support)
   • Example: 2560 cu. ft. (volume of space)÷50 cu.ft.=51.2 or 51,200(maximum Btu/Hr the space can support)
3. Add the Btu/Hr of all fuel-burning appliances in the space.
   • Vent-free heater Btu/Hr
   • Gas water heater  Btu/Hr
   • Gas furnace Btu/Hr
   • Vented gas heater Btu/Hr
   • Gas heater logs Btu/Hr
   • Other gas appliances  + Btu/Hr
   • Total = Btu/Hr
   • Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.
   • Example:
   • Gas water heater 30,000 Btu/Hr
   • Vent-free heater + 26,000 Btu/Hr
   • Total = 56,000 Btu/Hr
4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
   • Btu/Hr (the maximum the space can support)
   • Btu/Hr (actual amount of Btu/Hr used)
   • Example: 51,200 Btu/Hr(the maximum the space can support) 56,000 Btu/Hr (the actual amount of Btu/Hr used)
   • The space in the above example is confined because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.
   • You must provide additional fresh air. Your options are as follows:
   • A. Rework the worksheet by adding the space of an adjoining room. If the extra space provides an unconfined space, remove the door to the adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.
   • B. Install a lower Btu/Hr heater, if a lower Btu/Hr size makes the room unconfined. If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.
   • WARNING: If the area in which the fireplace may be operated is smaller than that defined as an 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.

Ventilation Air From lnside Building

This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12″ of the ceiling and one within 12″ of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code. NFPA 54/ANSI Z223.1. Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts. Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12″ of the ceiling and one within 12″ of the floor. 0 Clearance to Back wall. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code, NFPA 54/ANSI Z223.1, Section 5.3. Air for Combustion and Ventilation for required size of ventilation grills or ducts.

• IMPORTANT: Do not provide openings for inlet or outlet air into the attic if the attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.

• WARNING: Rework the worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces.

• NOTICE: This fireplace is intended for use as a supplemental fireplace. Use this fireplace along with your primary heating system. Do not install this fireplace as your primary heat source. If you have a central heating system, you may run the system’s circulating blower while using the fireplace. This will help circulate the heat throughout the house.

• WARNING: A qualified service person must install a fireplace. Follow all local codes.

• WARNING: Never install the fireplace:

  • in a bedroom or bathroom
  • in a recreational vehicle
  • where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the front, top, or sides of the heater
  • in high-traffic areas
  • in windy or drafty areas

• CAUTION: This fireplace creates warm air currents. These currents move heat to wall surfaces next to the fireplace. Installing a fireplace next to vinyl or cloth wall coverings or operating a fireplace where impurities (such as tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may discolor walls.

• WARNING: Maintain the minimum clearances. If you can, provide greater clearances from the floor, ceiling, and adjoining side and back walls.

INSTALLATION

IMPORTANT: Vent-free fireplace adds moisture to the air. Although this is beneficial, installing a fireplace in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, pages 5 through 6.

• CHECK GAS TYPE
  • Use only the type of gas indicated on the plate. If your gas supply can not meet that requirement, do not install a fireplace. Call the dealer where you bought a fireplace for the proper type of fireplace.
• CLEARANCES TO COMBUSTIBLES
  • (Vent-Free Operation Only) Carefully follow the instructions below. This fireplace is a freestanding unit designed to be set directly on the floor.

IMPORTANT: You must maintain minimum wall and ceiling clearances during installation. The minimum clearances are shown in Figure 4. Measure from the outermost point of the fireplace top.

Minimum Wall and Ceiling Clearances (see Figure 4)

• A. Clearances from the outermost point of the fireplace top to any combustible side wall should not be less than 12 inches.
• B. clearances from the fireplace top to the ceiling should not be less than 48 inches.
• C. Back wall O Clearance

CONNECTING TO THE GAS SUPPLY

• WARNING: A qualified service person must connect the fireplace to the gas supply. Follow all local codes.
• CAUTION: Never connect the fireplace directly to the gas supply. This fireplace requires an external regulator (not supplied). install the external regulator between the fireplace and the gas supply.

INSTALLATION ITEMS NEEDED
Before installing the fireplace, make sure you have the items listed below.

• piping (check local codes)
• sealant (resistant to natural or propane/LP gas)
• equipment shutoff valve*
• test gauge connection**
• sediment trap
• see joint
• pipe wrench
• Flexible gas hose (check local codes)

A CSA design-certified equipment shutoff valve with a 1/8″ NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 17.

WARNING: Never connect the fireplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

• The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 to 14 inches of water. If you do not reduce incoming gas pressure, fireplace regulator damage could occur. install external regulator with the vent pointing down as shown in Figure 6. Pointing the vent down protects it from freezing rain or sleet.
• CAUTION: Use only new, black iron or steel pipe. Internally-tinned cop-per tubing may be used in certain areas. Check your local codes. Use a pipe of 1/2″ diameter or greater to allow proper gas volume to the fireplace. If the pipe is too small, undue loss of pressure will occur.
• Installation must include an equipment shutoff valve, union, and a plugged 1/8″ NPT tap. Locate the NPT tap within reach for the test gauge hook-up. NPT tap must be upstream from fireplace (see Figure 7)
• IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance. Apply pipe joint sealant lightly to threads. This will prevent excess sealant from going into the pipe. Excess sealant in the pipe could result in clogged fireplace valves.
• CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.
  • We recommend that you install a sediment trap in the supply line as shown in Figure 7. Locate sediment trap where it is within reach for cleaning.
  • Install in piping system between fuel supply and heater. Locate sediment traps where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants.
  • This keeps them from going into fireplace controls.
  • If a sediment trap is not installed or is installed wrong, a fireplace may not run properly.
• CAUTION: Avoid damage to the regulator. Hold the gas regulator with a wrench when connecting to gas piping and/or fittings.
• NG MODELS: 5” to 10.5” W.C. Gas supplier provides external regulator for natural gas.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once.

INSPECTING BURNERS

• Chec k pi lot f lame pattern and burner flame patterns often.

PILOT FLAME PATTERN

• Figure 17 shows a correct pilot flame pattern.
• Figure 18 shows an incorrect pilot flame pattern.
• The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.
• If the pilot flame pattern is incorrect, as shown in Figure 18
  • shut off the fireplace.
  • see Troubleshooting, pages 15 through 16.

BURNER FLAME PATTERN

• Figure 19 shows a correct burner flame pattern.
• Figure 20 shows an incorrect burner flame pattern. If the burner flame pattern is incorrect,
  • shut the heater off (see Shut Off Gas to Appliance, page 10)
  • see Troubleshooting, pages 15 through 16

CLEANING AND MAINTENANCE

• WARNING: Disconnect power before attempting any maintenance or cleaning to reduce the risk of fire, electric shock, or personal injury. Turn off the heater and let cool before cleaning.
• Caution: Lable all wires before disc connect ion when servicing controls. Wiring errors can cause improper and dangerous operations. Verify proper operation after servicing.

DISCONNECT WIRING OR CONTROL MODULE

1. Remove four screws from the rear control panel, take out the thermostat sensing bulb from the clip, then disconnect the wires to free to control module from its mounting location.
   • Note: Do not confuse the mark on each wire.
2. Remove two screws and hex nuts, and take out the control module. When installing, reverse the steps above. (See Figure 22 and Figure 25)

DISCONNECT FAN

1. Remove screws from the fan bracket panel, pull the fan bracket panel out to remove. Then disconnect two wires to free the fan.
2. Mark or tag each wire removed for its exact reconnection. Remove the four screws from the fan .when installing, reverse the steps above. (See Figure 23 and Figure 25)
   • CAUTION: You must keep the control eas, burner, and circulating air passageways of the fireplace clean. Inspect these areas of the fireplace before each use. Have the fireplace inspected yearly by a qualified service person. The heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

CLEANING ODS/IGNITOR AND BURNER

Clean with a vacuum cleaner.

CLEANING MAIN AIR INLET HOLE
We recommend that you clean the unit every three months or after 2500 hours of operation. We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions on the can. If you don’t follow directions on the can, you could damage the pilot assembly.

1. Shut off the unit, including the pilot. Allow the unit to cool for atleast thirty minutes.
2. Inspect the burner, pilot, and primary air inlet holes on the injector holder for dust and dirt (see Figure 21).
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hair with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder.
6. In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4.

Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches f from where the pilot flame comes out of the pilot assembly (see Figure 24). With the unit of f, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.

CABINET

• Air Passageways
  • Use a vacuum cleaner or pressurized air to clean.
• EXTERIOR
  • Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabinet to remove dust.
• LOGS
  • If you remove logs for cleaning, refer to Installing Logs, page 21, to properly replace logs.
  • Replace log(s) if broken or chipped (dime-sized or larger).

MAIN BURNER

• Periodically inspect all burner flame holes with the fireplace running.
• All slotted burner flame holes should be open with a yellow flame present.
• All round burner flame holes should be open with a small blue flame present.
• Some burner flame holes may become blocked by debris or rust, with no flame present.
• If so, turn off the fireplace and let it cool. Either remove the blockage or replace the burner.
• Blocked burner flame holes will create soot.

TROUBLESHOOTING

• NOTE: BEFORE YOU SWITCH TO THE “ELECTRIC” CONTROL LEVEL FROM MANUAL CONTROL, YOU NEED TO TURN THE KNOB TO THE “OFF” LEVEL FIRST AND WAIT FOR ONE MINUTE, THEN TURN THE KNOB TO “ELECTRIC”. IN CASE OF “ELECTRONIC” CONTROL LEVEL DOES NOT WORK, PLEASE TURN THE CONTROL KNOB COUNTERCLOCKWISE TO “OFF” LEVEL AND WAIT FOR ONE MINUTE.
• WARNING: Make sure that power is turned off before proceeding.
• WARNING: Turn off and let cool before servicing. Only a qualified service person should service and repair the fireplace.
