LOCAL CODES PRODUCT FEATURES Install and use fireplace with care. Follow all local codes. In the absence of local codes, use the latest edition of The National Fuel Gas Code, ANSI Z223.1/NFPA 54*. *Available from: American National Standards Institute, Inc. 1430 Broadway New York, NY 10018 National Fire Protection Association, Inc. Batterymarch Park Quincy, MA 02269 UNPACKING CAUTION: Do not remove the data plates attached to the heater base assembly.
AIR FOR COMBUSTION AND VENTILATION 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. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home. Todayʼs homes are built more energy efficient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes.
AIR FOR COMBUSTION AND VENTILATION Continued 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 20 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 2880 cu. ft. (volume of space) If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space. 2.
AIR FOR COMBUSTION AND VENTILATION Continued Ventilation Air From Outdoors 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. 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, ANSI Z223.1/NFPA 54, Section 5.
INSTALLATION Continued WARNING: This appliance is equipped for (natural or propane/LP) gas. Field conversion is not permitted. Example * ELECTRICAL HOOKUP This fireplace normally operates under 120 VAC/60 Hz line voltage. The electrical cord supplied with your fireplace is five feet in length. You must locate fireplace within reach of a 120 volt grounded electrical outlet. If not, you must install an electrical outlet within reach of the fireplace power cord.
INSTALLATION Continued 3. Remove screws that attach fireplace floor assembly to fireplace. Open lower louver door. Carefully lift up fireplace floor assembly and remove from fireplace, taking care to pull flexible gas line through the access holes (see Figure 6). Note: Be careful of all wires on underside of log base. CAUTION: Do not pick up fireplace floor assembly by burners. This could damage burners. Only handle base by grates. Flexible Gas Line 4. Push first plastic bushing completely through hole.
INSTALLATION Continued Note: If you choose to relocate the wall switch assembly, do so before final installation into a mantel or recessing into a wall. If you are installing an optional blower accessory, install it at the same time you relocate the wall switch assembly. CAUTION: The wall switch assembly must never be mounted directly above the fireplace where heat may damage it.
INSTALLATION Continued 8. Remove paper template from wall. 9. Drill 3/8" holes at each mark. 10. Using a straight edge and pencil, connect the outer edges of the 4 holes for the rectangle (see Figure 10). This will give you cutting lines for the rectangle you will cut in the wall. 11. Using a keyhole saw, hack saw blade, drill, file or other suitable tool, carefully cut out the rectangular opening. Note: The corners of the rectangle may be round.
INSTALLATION Continued 13. Position wall switch assembly vertically over opening with decal lettering upright. Make sure wires freely pass through wall without binding. Align holes in wall plate with 1/8" pilot holes in mantel wall. 14. Drive mounting screws, removed in step 2 of Relocating Wall Switch Assembly on page 10, through wall plate holes and into pilot holes in mantel wall. 15. Tighten screws until wall switch assembly is firmly attached to mantel. Do not overtighten.
9. Check to make sure that all electrical cords are completely clear of the blower wheel and that there are no other foreign objects in blower wheel. Turn blower on and check for operation. Turn blower off by rotating knob fully counterclockwise before continuing. CAUTION: Never touch the blower wheel while in operation. WARNING: A qualified service person must connect fireplace to gas supply. Follow all local codes. B ol w M re to ro 10.
INSTALLATION Continued INSTALLING THERMOSTATIC BLOWER ACCESSORY NOTICE: Shut off gas supply and disconnect heater from gas supply if installing blower in previously installed fireplace. Contact a qualified service person to do this. 1. If fireplace screen and floor are still installed, see Removing Fireplace Screen and Floor Assembly, page 9. 2. Using screw provided, attach green ground wire from speed control cord to blower housing. Tighten screw securely (see Figure 18). 3.
INSTALLATION Continued WARNING: Failure to connect all wires properly as indicated may cause electrical short circuit or personal injury. A qualified electrician should check that all connections are made properly.
INSTALLATION INSTALLING GAS PIPING TO FIREPLACE LOCATION Continued 16. Reattach fireplace floor assembly with screws removed in step 3 of Removing Fireplace Screen and Floor Assembly, page 9. Note: Discard the remaining hardware items. After assembly, make sure all wires are completely clear of blower wheel. 17. Install logs (see Installing Logs, page 24) and fireplace screen (see Installing Screen, page 25).
INSTALLATION Continued CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to fireplace. If pipe is too small, undue loss of volume will occur. Installation must include an equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 24).
INSTALLATION Continued 3. Attach the flexible gas line to gas supply (see Figure 26). Check tightness of flexible gas line attached to gas regulator of fireplace (see Figure 26). 4. Check all gas connections for leaks. See Checking Gas Connections. 5. Replace fireplace floor assembly. Feed flexible gas line into fireplace base area while replacing fireplace floor assembly. Make sure the entire flexible gas line is in fireplace base area. Note: Be careful of wires and components on underside of fireplace floor.
INSTALLATION CONVENTIONAL FIREPLACE INSTALLATION Continued PRESSURE TESTING FIREPLACE GAS CONNECTIONS 1. Open equipment shutoff valve (see Figure 27, page 19). 2. Open main gas valve located on or near gas meter for natural gas or open propane/LP supply tank valve. 3. Place manual ignition switch in the OFF position. 4. Check all joints from equipment shutoff valve to gas valve (see Figure 28 or 29). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. 5.
INSTALLATION Continued 5. Route flexible gas line through access hole in hearth base. 6. Center cabinet mantel on hearth base (see Figure 31). Make sure mantel is flush against wall. 7. Break off nailing flanges (see Figure 32) with hammer or pliers. 8. Place cardboard or other protective material on top of hearth base. Carefully set fireplace on protective material, with back of fireplace inside mantel opening. 9. Attach flexible gas line to fireplace gas regulator.
INSTALLATION Continued 3. If not already completed, install gas piping to fireplace location. This installation includes an approved flexible gas line (if allowed by local codes) after the equipment shutoff valve. The flexible gas line must be the last item installed on the gas piping. See Installing Gas Piping to Fireplace Location, page 17. 4. Carefully set fireplace in front of rough opening with back of fireplace inside wall opening. 5. Attach flexible gas line to gas supply.
INSTALLATION Top Brass Trim Side Brass Trim Adjusting Set Screws Plate Slot Continued Wall board or facing material (above firebox) may be of combustible material, including decorative mantel ornaments or other similar projections off of the facing material.

OPERATING FIREPLACE Continued Note: You may be running this heater for the first time after connecting to gas supply or at the start of your heating season. If so, the ON button may need to be pressed again. This will allow air to bleed from gas system. If several attempts to light pilot fail, contact a qualified service person or gas supplier for repairs. Until repairs are made, light and operate manually (see Manual Lighting Instructions for Electrical Power Outage). 4.
