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

6. Installation and repair should be done by a qualied service person. To prevent malfunction and/or sooting, an unvented replace should be cleaned before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding materials, etc. It is imperative that control compartments, burners and circulating air passageways be kept clean.

7. WARNING! Any change to this heater or its controls can be dangerous.

8. Unvented fireplaces are a supplemental zone heater. They are not intended to be the primary heating appliance.

9. CARBON MONOXIDE POISONING: Early signs of carbon monoxide poisoning are similar to the u with headaches, dizziness and/or nausea. If you have these signs, obtain fresh air immediately. Have the heater serviced as it may not be operating properly.

10. The installation must conform with local codes or, in the absence of local codes, with the National Fuel

Gas Code, ANSI Z223.l/NFPA54.

11. This unit complies with ANSI Z21.11.2:19 Unvented Heaters.

12. Do not install the heaters in a bathroom or bedroom.

13. Proper location of the heater, and annual cleaning are necessary to avoid potential problems with sooting. Sooting, resulting from improper installation or operation, can settle on surfaces outside the replace.

14. Avoid any drafts that alter burner ame patterns. Do not allow fans to blow directly into replace. Do not place a blower inside burn area of rebox. Ceiling fans may create drafts that alter burner ame patterns. Sooting and improper burning will occur.

15. Caution: Candles, incense, oil lamps, etc. produce combustion byproducts including soot. Vent-free appliances will not lter or clean soot produced by these types of products. In addition, the smoke and/or aromatics (scents) may be re-burned in the vent-free appliance which can produce odors. It is recommended to minimize the use of candles, incense, etc. while the vent-free appliance is in operation.

16. This is an unvented replace. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventilation air must be provided. Refer to Page 8.

17. This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the National Fuel

Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code or applicable local codes.

18. Keep room area clear and free from combustible materials, gasoline and other ammable vapors and liquids.

19. Unvented replaces emit moisture into the living area. In most homes of average construction, this does not pose a problem. In houses of extremely tight construction, additional mechanical ventilation is recommended.

20. During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, lms or bonding agents. These chemicals are not harmful but may produce annoying smoke and smells

• In high tra󰀩c areas.

• In windy or drafty areas.

PLANNING THE INSTALLATION

In planning the installation for the replace it is necessary to determine where the unit is to be installed and whether optional accessories are desired. Gas supply piping should also be planned. The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a di󰀨erent sequence.

1. Position fireplace in desired location. Refer to the Fireplace and Framing Dimensions (page 7, Figures 2 and 3,) Fireplace Location (page 9, Figure 5) and Clearances and Height Requirements (page 10, Figures 6 and 7.)

NOTE: Be sure all cardboard packing material has been

removed from under the unit.

2. Install following the instructions found in this manual.

3. Field wire main power supply to junction box. Refer to the Electrical Installation section (page 15). (Electrical connections should only be performed by an experienced, licensed certied service person).

4. Plumb gas line. Refer to the Connect the Gas (page 13, Figure 10) section found in this manual. (Gas connections should only be performed by an experienced, licensed/certied service person).

5. Complete nish wall material and/or surround.

ADEQUATE COMBUSTION AND VENTILATION AIR

This heater shall not be installed in a conned space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.

The National Fuel Gas Code, (ANSI Z223.1/NFPA54), denes a conned space as a space whose volume is less than 50 cubic feet per 1,000 BTU per hour (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space, and an unconned space 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 a conned space.

Unusually tight construction is dened as construction where:

a. Walls and ceilings exposed to the outside atmosphere

have a continuous water vapor retarder with a rating of 1 perm (6 x 10 gasketed or sealed, and

b. Weather stripping has been added on openable win-

dows and doors, and

kg per pa/sec-m2) or less with openings

PRE-INSTALLATION INFORMATION

c. Caulking or sealants are applied to areas such as joints

around window and door frames, between sole plates and oors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical and gas lines and other openings.

The following formula can be used to determine the maximum heater rating per the denition of unconned space:

BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft

Consider two connecting rooms with an open area between, with the following dimensions:

L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.

BTU/Hr = (151/2 + 12) x (12) x (8)

If there were a door between the two rooms the calculation would be based only on the room with the heater.

BTU/Hr = (151/2) x (12) x (8)

SECURE FIREPLACE TO FRAMING

AVFLST Vent Free Fireplace

The replace must be secured to the framing studs as shown in Figure 8. Use eight (8) screws to attach replace to framing. The side nailing anges are 1⁄2" or 5⁄8" to accommodate di󰀨erent wall thickness.

WARNING!

Never install combustible materials over front

face of replace.

FINISHING MATERIAL

NOTE: Any remote wiring (i.e. remote control, wall

switch), must be done prior to nal nishing to avoid costly

reconstruction.

Only noncombustible materials (i.e. brick, tile, slate, steel, or other materials with a UL re rating of Zero) may be used to cover the black painted face of the appliance. It is permissible to bring combustible wall board to the top of the stando󰀨s on the top and to the wall board stand-o󰀨s on the sides of the unit. A 300°F minimum adhesive may be used to attach facing materials to the black surface. If joints between the nished wall and the replace surround are sealed, a 300°F minimum sealant material (General Electric RTV103 or equivalent) must be used. NOTE: Fireplace may be installed on top of framing or platform constructed of combustible materials which do not protrude beyond the face.

NONCOMBUSTIBLE FACING INSTALLATION

CAUTION: The noncombustible wall board supplied with

this unit can be damaged if dropped or struck. Handle with care.

1. Using drywall screws, secure the noncombustible board to the two brackets on top of the unit. IMPORTANT: To avoid cracking the board, pre-drill holes prior to securing to the unit/framing.

2. Wipe any debris or dust from the noncombustible board and drywall.

3. It is highly recommended to prime the facing using a quality primer prior to taping and mudding. This will ensure proper adhesion of both the tape and mud. The supplied board is very porous.

4. Tape the seams using a mesh type tape.

5. Mud seams as normal. We recommend using a product called Durabond high strength compound for the rst coat. This product can be purchased at any hardware store. Follow manufacturer's recommendations for curing the mud. NOTE: Depending upon the nal nishing method, use a minimum rated 300 degree sealant, drywall compound or thin set to seal the side and top joints.

6. Prime wall for a second time for proper adhesion of paint.

CONNECT THE GAS

NOTICE: A qualied gas appliance installer must connect

the heater to the gas supply. Consult all local codes.

►

Note: Gas line may be installed on the left or right side of the appliance.

WARNING!

This appliance is equipped for either natural or propane

gas. Field conversion is not permitted.

WARNING!

Use new black iron or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Code, section 2.6.3, providing gas meets hydrogen sulde limits, and where permitted by local codes. Gas piping system must be sized to provide minimum inlet pressure (Listed on Data Plate) at the maximum ow rate (BTU/hr). Undue pressure loss will

occur if the pipe is too small.

A manual shutoff valve must be installed upstream of the appliance. Union tee and plugged 1⁄8" NPT pressure tapping point should be installed upstream of the appliance. Figure

A sediment trap should be installed upstream to prevent moisture and contaminants from

passing through the pipe to appliance controls

and burners. Failure to do so could prevent the appliance from operating reliably. Figure 10

FIREPLACE INSTALLATION

WARNING!

CHECK GAS TYPE: The gas supply must be the

same as stated on the heater’s rating plate. If the gas supply is di󰀨erent, DO NOT INSTALL THE HEATER. Contact your dealer for the correct model.

IMPORTANT: Loosen the pipe adapter on the ex tube before installing to the system piping.

Always use an external regulator for all propane/LPG heaters only, to reduce the supply tank pressure to a maximum of 13" w.c. This is in addition to the internal regulator in the heater valve.

Detailed Component Operating Instructions— Intellire™ Plus ODS

Control Module Operation

1. The control module has an ON/OFF/REMOTE selector switch that must be set. See Figure 19.

OFF Position: Appliance will ignore all power inputs and

will not respond to any commands from a wall switch or remote. The unit should be in the OFF position during installation, service, battery installation, fuel conversion, and in the event that the control goes into LOCK-OUT mode as a result of an error code.

ON Position: Appliance will ignite and run continuously

in the HI ame setting, with no adjustment in ame output. This mode of operation is primarily used for initial installation or power outage operation with battery backup.

REMOTE Position: Appliance will initiate commands

from an optional wired wall switch and/or the wireless remote (RC300).

2. If using a wired wall switch with the module in REMOTE mode, the ame output can be adjusted with the HI/LO selector switch on the module. See Figure 19. Note that the ame HI/LO selector switch will become inactive once a remote control (RC300) is programmed to the control module. Note that the control module will always ignite the replace on HI and remain so for the initial 10 seconds of operation. If the HI/LO is switched to the LO position, the ame output will automatically drop to the lowest setting after the ame has been established for 10 sec. After this 10 second period, the ame can be adjusted from HI to LO with the switch.

3. The control module has safety feature that automatically shuts down the replace after 9 hours of continuous operation without receiving a command from the RC300 remote.

4. If you intend to use both an optional wired wall switch and the RC300 remote control to operate your replace, the wall switch will override any commands given by the remote.

5. Module Reset

This module may lock-out under certain conditions.

When this occurs, the appliance will not ignite or respond to commands. The module will go into lock-out mode by emitting three audible beeps, then continuously displaying a RED/GREEN error code at its status indicator LED.

• Check battery tray. Remove batteries if installed. Batteries should only be installed for use during power outages.

• Locate the module selector switch. (See Figure 19).

The pilot ame must always be present when the

heater is in operation. It should just touch the top of the thermocouple tip for natural gas. Refer to Figure 20 for correct pilot ame.

If the pilot ame does not touch the thermocouple, then the main burner cannot function reliably. Refer to Figure 21 for incorrect shape of pilot ame.

OPERATING INFORMATION

Avoid any drafts that alter burner ame patterns. Do not allow fans to blow directly into the replace. Do not place a blower inside the burn area of the rebox. Ceiling fans may create drafts that alter ame patterns. Sooting and improper burning will result.

During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, lms, or bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as they are burned o󰀨 during the initial operation of the appliance possibly causing headaches or eye or lung irritation. This

is a normal and temporary occurrence.

The initial break-in operation should last two to three hours with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in period will be slight and will disappear with continued use.

This appliance must not be used with glass doors.
