Page 16: Connecting The Gas
CONNECTING THE GAS NOTICE: A qualified gas appliance installer must connect the heater to the gas supply. Consult all local codes. Use new black or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Code, section 2.6.3, providing gas meets hydrogen sulfide 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 flow 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 " NPT pressure tapping point should be installed upstream of the appliance. - Page 17 CONNECTING THE GAS CHECK GAS TYPE: The gas supply must be the same as stated on heater's rating plate. Located behind the control access door (Figure 1, page 5). If the gas supply is different, DO NOT INSTALL the heater. Contact your dealer for the correct model. Connecting to the wrong gas type may result in property damage or personal injury. Connecting directly to an unregulated propane/L.P.G.

Page 22: Log Placement
LOG PLACEMENT Before you begin — This unit is supplied with six (6) ceramic fiber logs. Do not handle these logs with your bare hands. Always wear gloves to prevent skin irritation from ceramic fibers. After handling the logs, wash your hands gently with soap and water to remove any traces of fibers. The positioning of the logs is critical to the safe and clean operation of this heater. Sooting and other problems may result if the logs are not properly and firmly positioned in the appliance. Never add additional logs or embellishments such as pine cones, vermiculite or rock wool to the heater. Only use the logs and TPB-RW (rock wool) supplied with the unit. Failure to position the parts in accordance with diagrams below or to use only parts specifically approved for this heater may result in property damage or personal injury. - Page 23 LOG PLACEMENT 3.

Page 26: Flame Appearance
FLAME APPEARANCE Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed. In addition, periodically check the flames visually during operation. CHECkING THE PILOT FLAME The pilot flame must always be present when the heater is in operation. It should just touch the top of the ther- mocouple tip for natural. See Figure 31 for correct pilot flame. If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. See Figure 32 for incorrect shape of pilot flame.

OPERATING INSTRUCTIONS FOR YOUR SAFETY READ BEFORE LIGHTING If you do not follow these instruction exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance is equipped with a piezo ignition device which automatically lights the pilot. If pilot is not working see Match Lighting Instructions on page 30. B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS: • Do not attempt to light any appliance. • Do not touch any electric switch; do not use any phone in your building. -
Page 29: Milli-Volt Control Lighting Instructions
OPERATING INSTRUCTIONS MILLI-VOLT/THERMOSTAT CONTROL LIGHTING INSTRUCTIONS 1. STOP! Read the safety information label. 2. Make sure the manual shutoff valve is fully open. 3. This gas log set is equipped with an ignition device (piezo) which automatically lights the pilot. If piezo ignitor does not light the pilot, refer to instructions for “Match Lighting Instructions,” page 30. 4. Turn gas control knob clockwise to the OFF position and turn ON/OFF switch to OFF position. 5. Wait (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow "B" in the safety information label. If you don't smell gas, go to next step. 6. From OFF position, turn the gas control knob counterclockwise to IGN position. Push in control knob for 5 seconds. NOTE: If you are running the heater for the first time, it will be necessary to press in the control knob for 30 seconds to allow air to bleed out of the gas piping. 7. With the control knob pushed in, push in and release the piezo ignitor button to light the pilot. -

OPERATING INSTRUCTIONS BLOWER OPERATION MATCH LIGHTING INSTRUCTIONS 1. Remove any items necessary for easy access to the pilot (for example: logs, screens, etc.). 2. Follow appropriate lighting instructions found previously. Instead of pushing and releasing the piezo button, light a match and hold the flame to the end of the pilot and ignite the pilot. 3. After control knob has been released and pilot stays lit, reinstall any items that were removed for pilot access. 4. Call a qualified service technician for repair or replacement of the piezo ignitor.

Page 31: Cleaning And Servicing
CLEANING AND SERVICING Annual inspection and cleaning by your dealer or qualified service technician is recommended to prevent malfunction and/or sooting. Turn off heater and allow to cool before cleaning. Disconnect electrical power before cleaning or servicing. Remove logs, handling carefully by holding gently at each end. Gloves are recommended to prevent skin irritation from ceramic fibers. If skin becomes irritated, wash gently with soap and water. Refer to manual for correct log placement. PERIODIC CLEANING - Refer to parts diagram for location of items discussed below. • Do not use cleaning fluid to clean logs or any part of heater. • Brush logs with soft bristle brush or vacuum with brush attachment. • Vacuum loose particles and dust from the front and rear burner, control and piezo covers and grate weldment. • Inspect and clean burner air intake holes. Remove lint or particles with vacuum, brush, or pipe cleaners. Failure to keep air intake holes clean will result in sooting and poor combustion. -
