320008056
WARNING: If the area in which the heater 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/NFPA 54, Section 5.3, (or applicable local codes).
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a confined 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 unconfined 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 the unconfined space.
Important Safeguards
WARNING: During manufacturing, fabricating and
shipping, various components of this appliance are treated with certain oils, films or bonding agents. These chemicals are not harmful but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance, possibly causing headaches and eye/lung irritation. This is a normal and temporary occurrence.
Although your gas logs are very realistic in appearance, it is not a real wood-burning fireplace and must not be used for burning rejected material.
To avoid irreparable damage to the appliance or personal in jury; matches, paper, garbage or any other material must not be placed or thrown on top of the logs or into the flames.
To avoid personal injury, do not touch hot surfaces when the appliance is operating.
Touch only the piezo button and control knob. Avoid contact with the front screen, canopy or any other part which will be very hot.
Always ensure that the fireplace screen is in place when the appliance is operating and, unless other provisions for combustion air are provided, the screen shall have opening(s) for introduction of combustion air.
Close supervision is necessary when the appliance is be­ing operated near children.
Do not use to cook food.
If this is the ONLY gas appliance, we recommend a minimum 200 pound cylinder with a fill gauge. Use of a 100 pound cylinder is not recommended. Other household gas appli­ances may require the tank size to be larger. Do not operate the vent free fireplace if the fuel level in the propane tank is below 1/4 full.
-
WARNING: The glowing ember base and all the logs are manufactured from bonded ceramic fiber. This is a commonly used material in indus­try worldwide. In the event of the logs and base being removed, care should be taken not to dam­age the bonded material. Intentional misuse of, or deliberately fragment­ing, the material could lead to inhaling fibers and be injurious to health.
This appliance is intended to be used only for supplemental heat. Do not use it routinely as a primary heat source. Continuous operation could produce excessive humidity de­pending on construction characteristics and outdoor tempera­tures (below 20°F). Over time, this could cause condensation to form and damage wall structures and exterior paint.
WARNING: Failure to keep primary air opening(s) of the burner(s) clean may result in sooting and property damage.

Pressure Test Points
The gas control is equipped with a captured screw-type pressure test point, therefore it is not necessary to pro­vide a 1/8” test point upstream of the control.
Odor During Operation
Neither natural gas nor propane gas give off an odor when burned. The nature of a vent free combustion system, however, is such that odors may occasionally be produced during heater operation when impurities exist in the immediate area. Cleaning solutions, paint, solvents, cigarette smoke, candles, adhesives, new car­pet or textiles, etc., all can create fumes. These fumes may mix with combustion air and can create odor. Such odors will disappear over time, however, the condition can be alleviated by opening a window or otherwise providing additional ventilation to the area.
WARNING
This appliance is for installation in a solid-fuel burning masonry, fireplace with a working flue, a U.L.-127 listed manufactured solid-fuel burn­ing fireplace, in any Majestic ventless firebox, or in any listed ventless firebox enclosure certified to I.A.S. U.S. Requirement 2-97 or ANSI Z21.91.
NOTICE
This is an unvented gas-fired heater. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventila­tion air must be provided. Refer to Pages 7 and 8.

Provisions for Adequate Combustion and Ventilation Air
WARNING: This heater shall not be installed in a confined space or unusually tight construc­tion unless provisions are provided for adequate combustion and ventilation air.
Today’s homes are built more energy efficient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible.
While it is good to make your home energy efficient, you need fresh air. All fuel-burning appliances need fresh air for proper combustion.
Supplying Adequate Ventilation
This appliance must be installed in an unconfined space. The following information will help you classify your space and
provide adequate ventilation for complete combustion.
An Unconfined Space
feet for each 1000 BTU/Hr input rating of all appliances in the space. (4.8 M3 per kw), (cubic feet equals length x width x height of space).
A Confined Space

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 heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space (length x width x height). Length x Width x Height = _____cu. ft. (volume of space) Example: Space size 25’ (length) x 25’ (width) x 8’ (ceiling
height) = 5,000 cu. ft. (volume of space)
If additional ventilation from adjoining room(s) is supplied
with grills or doorless openings, add the volume of these rooms to compute the total volume of the applicable 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: 5,000 cu. ft. (volume of space) ÷ 50 cu. ft. = 100
or 100,000 (maximum BTU/Hr the space can support)
3. Add the BTU/Hr of all gas burning appliances in the space.
Gas range BTU/Hr Vented gas heater BTU/Hr Gas fireplace logs BTU/Hr Other gas appliances* + Total = BTU/Hr Example: Gas range 60,000 BTU/Hr Vent-free logs + Total = 89,000 BTU/Hr *Do not include direct-vent gas appliances. Direct-vent draws
combustion air from the outdoors and vents to the outdoors.
BTU/Hr
29,000 BTU/Hr
4. Compare the maximum BTU/Hr the space can support with the actual amount of BTU/Hr used.
__________ BTU/Hr (maximum the space can support) __________ BTU/Hr (actual amount of BTU/Hr used) Example: 100,000 BTU/Hr (max. the space can support)
89,000 BTU/Hr (actual amount of BTU/Hr used)
The space in the above example is an unconfined space because the actual BTU/Hr used is less than the maximum BTU/Hr the space can support. If the space had been confined, your options would be as follows:
A. Rework worksheet, adding the space of an adjoining
room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Build ing.
B. Install a lower BTU/Hr heater, if lower BTU/Hr size
makes room unconfined.
Converting Confined Space to Unconfined Space
Additional volume to convert a confined to an unconfined space could come from an adjoining space. When using an adjoining space, you can 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 3, Figure 2), or remove the door into the adjoining room.
Ventilation Air From Outdoors for Unusually Tight Construction
WARNING: If the area in which the heater 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/NFPA 54, Section 5.3 or applicable local codes.
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 X 10.11 kg per pa-sec-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.
You may provide two permanent openings: one within 12” of the ceiling and one within 12” of the floor. 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:
attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.

Installation
Unpacking
Open the carton and remove the logs and the chassis. Remove each of the logs by gripping at either end of the log while avoid­ing any undue pressure. Please note that the logs have been marked for positive identification.
The carton for all models contains the following: chassis, front log (#1), rear log (#2), top log (#3), [log (#4), log (#5) are in­cluded with larger models], 2 screws and a bag of volcanic ash.
Fireplace Preparation
The fireplace needs to be prepared before installing the unit: A. Turn off the gas supply if the gas line has been run to the
fireplace.
B. WARNING: Before installing logs in fireplace, the chim-
ney flue and firebox must be cleaned of soot, creosote, ashes and loose paint by a qualified chimney cleaner or sooting will occur.
Note: If your fireplace has been cleaned using chemicals or
solvents, these products may have been absorbed into the fireplace hearth and walls and will be burned off during the initial break-in period.
C. Any outside air ducts and/or ash dumps in the fireplace shall
be permanently closed and sealed at the time of appliance installation. This will prevent drafts from disturbing the flames and interfering with complete combustion of the gas fuel.
Location
When gas logs are to be installed in a fireplace, inspect the area surrounding it for possible air drafts that may affect the flames and possibly cause sooting. Such drafts may be caused by a ceiling fan near the fireplace, a hot air furnace register or an open door. When burning the logs, carefully observe the effect of possible drafts on the flames and take appropriate measures to eliminate them. For example, the ceiling fan may be cut off, the hot air register closed, etc.
Centrally locate the gas logs in the fireplace deep enough into the firepit to accomplish an adequate draft (if use as a vented appliance is planned). Ensure that the front feet of the grate sit inside the front edge of the fireplace. Be sure fireplace meets minimum fireplace dimensions.
To avoid any movement of the unit during operation, screw the chassis to the floor of the fireplace using the screws provided. Failure to do so could cause gas leaks.
Two brackets are provided. Place brackets over front grate legs as shown in figure 3. After locating the chassis correctly in the fireplace, mark the hole positions on the fireplace floor. Drill two holes approximately 1/2” deep.
Use the two screws to secure the brackets to the fireplace floor, (Fig. 3)
even when the appliance will be used as a vented decorative appliance in case local codes change to allow unvented space heaters or in the event that the flue damper is inadvertently closed.
Clearances for unvented installation in existing fireplaces, (jurisdiction permitting)
1. Sidewall Clearances: Clearances from the side of the
fireplace opening to any combustible wall should not be less than 16”. (Fig. 4A)
2. Ceiling Clearances: The ceiling height should not be less
than 42” from the top of the fireplace opening. (Fig. 4A)
3. Mantel Clearances: The use of a canopy* is optional de-
pending on mantel clearances to the fireplace opening and projection profile.
NOTE: Mantel clearances may differ for each vent-free fire-
box. Refer to the firebox installation instructions for clear ances.
A. Mantel profile: The minimum distance above the fire-
place opening to combustible material projecting 11/8” (tile moldings, breast boards, etc.) is 15”.
Combustible material projecting 6” (a mantel shelf, for
example) requires a minimum clearance of 19” above the fireplace opening. Required clearance varies with the amount of projection. (Fig. 4B)
The mantel profile must fall within the cross-section
shown in figure 4B (if no canopy is used) or 4C (if a canopy is used).
B. With canopy*: The minimum distance above the fire-
place opening to combustible material projecting 1¹⁄₈" (tile moldings, breast boards, etc.) is 8".
Combustible material projecting 6" (a mantel shelf, for
example) requires a minimum clearance of 12" above the fireplace opening. Required clearance varies with the amount of projection. (Fig. 4C)
C. Heat resistant material: Any heat resistant mate-
rial suitable for a continuous operating temperature of 120°C (248°F) must cover the wall surface directly above the fireplace opening and extend the full width of the fireplace opening for a distance of 10” above the opening if no canopy is used, (8” if a canopy is used). (Figs. 4B

Gas Connection
Check Gas Type. Use only the gas type indicated on the
heater’s rating plate. If the gas type indicated on the plate is not your type of gas supply, DO NOT INSTALL. Contact your dealer for the proper model.
WARNING
DANGER OF PROPERTY DAMAGE,
BODILY INJURY OR DEATH.
Make sure the heater is equipped to operate on the type of gas available. Models designated as natural gas are to be used with natural gas only. Heaters designated for use with liquefied petro­leum (l.p.) gas have orifices sized for commercial­ly pure propane gas. They cannot be used with butane or a mixture of butane and propane.
Gas Piping. The gas supply line must be of an adequate size
to handle the BTU/HR requirements and length of the run for the unit being installed.
Determine the minimum pipe size from the piping size chart on Page 12. The normal gas connection at this appliance is 1/2” NPT made at the left of the unit.
Always use an external regulator for all LP installations to reduce the supply tank pressure to a maximum of 13” w.c. This is in ad dition to the regulator fitted to the heater.
All piping must comply with local codes and ordinances or with the National Fuel Gas Code (ANSI Z223.1/NFPA 54), whichever applies.
WARNING: Connecting directly to an unregulated LP tank can cause an explosion.
Gas Connection. If installation is for L.P. gas, have L.P. in-
staller use two-stage regulation and make all connections from storage tank to heater. Refer to the National Fuel Gas Code for the proper supply tank size with the Btu’s/Hr requirements. If this is the ONLY gas appliance, we recommend a minimum 200 pound cylinder with a fill gauge. Use of a 100 pound cylinder is not recommended. Other household gas appliances may require the tank size to be larger.
Use two pipe wrenches when making the connection to the valve to prevent turning or damage to gas valve or regulator.
Connection between the manual shut-off valve and the gas valve can be made with a CSA design certified flexible connec tor if allowed by local codes. A 10 inch, 1/2” NPT listed stain­less steel flexible connector is supplied with the gas log heater. Tighten all joints securely.
CAUTION: Failure to install a drip leg (sediment trap) may result in improper combustion that will produce soot. Reference Sections 3.7 and 5.5.7 and Figure 5.5.7 of the National Fuel Gas Code for guidance.
-
-
Typical Gas Line Connection
Step 1: With the engine assembly free from the fireplace, check tightness of flexible connector fittings.
CAUTION: Use one wrench to hold the valve and one wrench to loosen and tighten the brass adapter and the flex line connection. Failure to hold the valve while loosening and tightening the fittings can damage the unit and cause gas leaks.
Step 2: Set the engine assembly into the fireplace and connect the flexible connector to the gas piping that has been installed per local codes, or in the absence of local codes, ANSI Z223.1/ NFPA 54 latest edition.
Step 3: After the last connection is made, screw the engine as sembly to the bottom of the fireplace. (Fig. 3)
Step 4: Test all connections on the unit and piping for gas leaks.
Testing the Gas Piping. Test all piping for leaks. When check ing gas piping to the heater with gas pressure less than 1/2 PSI, shut off manual gas valve for the heater. If gas piping is to be checked with the pressure at or above 1/2 PSI, the heater and manual shut off valve must be disconnected during testing to prevent damage to the regulator on the unit, (see warning
below).
WARNING
DANGER OF PROPERTY DAMAGE,
BODILY INJURY OR DEATH.
Never use a match or open flame to test for leaks. Never exceed specified pressures for testing. High pressures may damage the appliance regulator which would re­quire replacement. Liquefied petroleum (L.P.) is heavier than air and it will settle in any low area, including open depressions and it will remain there unless area is ven­tilatedNever attempt start-up of unit before thoroughly ventilating area.A.
WARNING: Be sure that the gas type indicated on the gas log rating plate concurs with the gas system in your building.
To ensure that the gas lines and connections do not have any leaks, a pressure test should be performed. Only a qualified
installer should perform the pressure test to ensure that the unit is not damaged by high pressures!
If you connect natural gas to an LP gas unit, you may be un­able to ignite the pilot. If the pilot does ignite, the front burner flame on the low setting will be bright blue but only 1/4” to 1/2” long and most likely lifting off the burner ports. If this is the case, turn the unit off immediately and contact the dealer where the unit was purchased.
If you connect LP gas to a natural gas unit, the front burner flame on the low setting will be about 6” - 8” long. On the medium and high setting, the front burner flames will be bright yellow and about 10” in length. Turn the unit off immediately! If the unit is allowed to run in this condition, substantial amounts of soot will be generated and emitted into the house. Contact the dealer where the unit was purchased.

Gas Line Pipe Sizing
NOTE: To determine the size of the branch gas line from the main gas line to the fireplace, enter the tables below (for iron pipe or copper tubing) using the distance from the gas meter or second stage regulator to the furthest appliance on the gas system. Select a pipe or tube diameter which has enough capacity to meet the maximum input requirement of the fireplace. Regardless, do not use less than 1/2” diameter for the branch line. For any distances required longer than shown in these tables, refer to the National Fuel Gas Code.
NOTE: There may be a local gas utility requirement specifying a minimum diameter for gas piping. All units require a 1/2 inch pipe con­nection at the gas valve.

WARNING: Use only internally tinned copper tubing. If correct copper tubing is not used, tubing can deteriorate and develop gas leaks.
Gas Pressure Check
Check the inlet pressure to the appliance to ensure that it is as shown in Table 1. Also check the incoming gas pressure where the field installed gas line connects to the gas logs.
The manifold pressure is controlled by the regulator and should be checked at the pressure test point located downstream from the regulator on the control valve body. Access to the pressure test point is obtained by removing all logs and the heat shield on the right hand rear side of the base. The pressure test point 1/8” NPT plugged tapping is located on the rear face of the control body. (Fig. 5)
The pressure should be checked with the appliance burning on high (highest setting) and all other gas appliances turned on. One must then read the manometer and if pressures are not 10” w.c. for LP or 3.5” w.c. for natural gas, then the inlet pres­sure must be adjusted or increased until the proper pressures are attained. If these pressures are greater than 10” w.c. for LP or 3.5” w.c. for natural gas, contact your gas supplier before operating the appliance.
The pressure regulator is preset and locked to prevent tamper­ing. If the pressure is not as specified, replace the regulator with part # 73332 (for natural gas only), or part # 73333 (for L.P. gas only).

Flame Check
A periodic visual check of the flames should be made. The pilot flame should always be present when the appliance is in opera tion. (Fig. 10)
In normal operation (at full rate for approximately 15 minutes) the following flame appearance should be observed:
Natural Gas
Propane Gas
Main BurnerFlame: The flame should be yellow in color and
should extend about 6 inches above the large front log. Typical flame shape as seen in Figure 11.
­NOTE: For your safety, the appliance is equipped with an oxygen depletion system. The system senses the oxygen in the atmosphere and switches off the gas supply in case the level of oxygen falls below a safe level. It must not be altered in any
way.

Managing Heat Output
When installed in a wood burning fireplace, the heat output from the appliance can be controlled by the position of the flue damper if it is installed in a wood-burning fireplace.
The damper setting should be fully closed for maximum heat output, partially closed for less heat output and fully open for minimum heat output.
The appliance may be used in a working solid fuel burning fire­place with the flue damper closed only if unvented appliances are permitted by local state and city codes. It may also be
Maintenance
Cleaning
CAUTION: Before cleaning or moving logs or other parts of the
unit, be sure to read the section on important safeguards. Cleaning should be done before the logs are used each year
and after long periods of non-use. All cleaning should be carried out when the appliance is cold. Only limited cleaning will be required under normal use. Dust-
ing the front grate or the control knob panel may be required occasionally. Do not use any cleaning fluids to clean the logs or any other part of the appliance.
If the flames show any unusual shapes or behavior, or if the burners fail to ignite properly, then the burner holes may require cleaning. If this occurs contact your nearest dealer to get the appliance serviced.
T123

operated as a decorative appliance whose prime function lies in the aesthetic effect of the flames when installed in a solid fuel burning fireplace with the flue damper open. If unvented heat­ers are not permitted, the fireplace vent damper must be locked at a minimum vent area of 15 sq. ins.
Whenever the appliance is operated with the fireplace’s flue damper closed, glass doors - if present - must be open and the outside air damper and the ash dump (if the fireplace is equipped with either one) must be closed.
Alternatively, the appliance can be cleaned by removing the top, front and rear logs. Handle the logs gently so as not to damage them. Always lift each log by holding it carefully at each end.
After the logs are removed allowing access to the burner area, use a vacuum cleaner to carefully remove dust, spider webs and loose particles from the base, logs and from around the burner. Gloves are recommended to prevent the ceramic fibers that compose the logs from pricking your skin. If the skin is pricked, wash gently with soap and water. Use extreme cau­tion in clearing around the pilot (ODS). The pilot should not be moved or altered from the original factory setting (Pilot to burner preset location). The burner should not be removed or taken out of it’s locked and secure position (proper location of burners are critical).

Positioning Logs
The logs must be positioned ONLY as illustrated in Figures 12, 13 and 14
Position the front log so that the large notch in the underside
of the right end of the log fits securely and rests on the sheet metal control cover as shown in Figure 15. The front right end of the log has a ‘V’ shaped notch to touch the back of the right-hand grate bar as shown in Figure 16. The left under­side of the front log has a tab that will fit into mating slot in the ember base. When the log is properly placed, there should be no gap between the right underside of the front log and the top edge of the ember base.
CAUTION: Failure to position these parts as they are
described in these instructions will cause improper com­bustion and may result in soot being produced.
Position the rear log so that the notches in the back of the
log go around and up against the vertical bars of the grate assembly. Install the rear log behind the log spacer brackets. The bracket in the center of the burner assembly must fit into the hole in the center underside of the back log. (Refer to Figure 17 for proper placement of the rear log.)
Position the top log so that its tongue fits securely into the slot
on the top of the rear log and the peg fits into the hole in the top of the front log. The top log, when properly positioned, establishes the correct spacing between the front and rear logs.
The left and right twigs are to be placed into the appropriate
notches provided in the front and rear logs as shown. (Figs. 12, 13 and 14)
When using the Charred Oak log set the rear standoff must
be cut to allow the rear log to be positioned properly. (Fig.
17)
ENSURE THAT THE LOGS ARE CENTRAL AND VERTICAL AS SEEN FROM THE SIDE. TO PREVENT UNWANTED SOOTING, THE FLAME FROM THE BACK BURNER SHOULD NOT TOUCH ANY LOG.
CAUTION: Proper location is critical. When positioning the log set, make sure that the logs do not interfere with the sides of the fireplace before securing the chassis.
Fireplace Screen
The fireplace screen must be in place when the appliance is operating and unless other provisions for combustion air are made, the screen must have openings for the introduction of combustion air.
Decorative Volcanic Ash
The volcanic ash from the bag provided should be sprinkled over the baseplate in front of and below the main burner. Do not sprinkle this material on the fiber base, around the pilot or on the main burner.
