SAFETY INFORMATION FOR USERS OF LP-GAS Propane (LP-Gas) is a flammable gas which can cause fires and explosions. In its natural state, propane is odorless and colorless. You may not know all the following safety precautions which can protect both you and your family from an accident. Read them carefully now, then review them point by point with the members of your household. Someday when there may not be a minute to lose, everyone's safety will depend on knowing exactly what to do.
IMPORTANT INSTALLATION GUIDELINES Proper Primary Airflow into Burner For proper burner operation and flame appearance, the flow of primary air into the venturi tube, located on the rear of the burner, must not be reduced. This flow of air is reduced if dirt, lint or other obstructions build-up around or inside the venturi. Any obstruction in the venturi tube area must be removed.
INTRODUCTION Instructions to Installer 1. Installer must leave instruction manual with owner after installation. 2. Installer must have owner fill out and mail warranty card supplied with unvented room heater. 3. Installer should show owner how to start and operate unvented room heater. Always consult your local Building Department regarding regulations, codes or ordinances which apply to the installation of an unvented room heater.

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 BTU's (.3KW's) of gas input per hour. Unvented room heaters are recommended as supplemental heat (a room) rather than a primary heat source (an entire house). In most supplemental heat applications, the water vapor does not create a problem.
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR (continued) The space in the above example is a confined space 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 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 Building. B.
GAS SUPPLY The gas pipeline can be brought in through the right or left side of the appliance. The insert has a Flexline with shutoff valve located on the right side when facing the unit.

OPERATION INSTRUCTIONS/FLAME APPEARANCE Flames from the pilot (front center of burner) as well as the main flame should be visually checked as the fireplace is installed. In normal operation at full rate after 10 to 15 minutes, the flame appearance should be sets of yellow flames. Notice: All flames will be random by design, flame height will go up and down. Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into fireplace.
PILOT FLAME CHARACTERISTICS Figures 25 and 26 show a correct pilot flame pattern. The correct flame will be blue and will extend beyond the thermocouple. The flame will surround the thermocouple just below the tip. A slight yellow flame may occur where the pilot flame and main burner flame meet. Figures 27 and 28 show 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.
PILOT FLAME CHARACTERISTICS Cleaning and Maintenance/Pilot Oxygen Depletion Sensor Pilot (Figures 29 and 30) When the pilot has a large yellow tip flame, clean the Oxygen Depletion Sensor as follows: 1. Clean the ODS pilot by loosening nut B from the pilot tubing. When this procedure is required, grasp nut A with an open end wrench. 2. Blow air pressure through the holes indicated by the arrows. This will blow out foreign materials such as dust, lint and spider webs. Tighten nut B also by grasping nut A.
