IMPORTANT SAFETY INFORMATION IMPORTANT: Read this owner’s manual carefully and completely before trying to assemble, operate, or service this heater. Improper use of this heater can cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning. Only a qualified installer, service agent, or local gas supplier may install and service this product.
which the strong wind would shut down the appliance. gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa). 4. This heater needs fresh air ventilation to run properly. This heater has an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS shuts down the heater if not enough fresh air is available. See Air for Combustion and Ventilation, page 7. If heater keeps shutting off, see troubleshooting. 14.
WARNING: Combustion by-products produced when using this product contains carbon monoxide, a chemical known to the State of California to ca use birth defects (or other reproductive harm known to cause cancer) QUALIFIED INSTALLING AGENCY Only a qualified agency should install and replace gas piping, gas utilization equipment or accessories, repair and service the heater.
INSTALLATION CHECKLIST Share this checklist with your professional installer Manifold Pressure and Nominal Inlet Pressure for appropriate gas type o Using Natural Gas: Minimum Inlet Pressure (W.C): 6” Manifold Pressure (W.C.): 5.2” Nominal Input Pressure (W.C.): 7” o Using Propane Gas: Minimum Inlet Pressure (W.C): 8” Manifold Pressure (W.C.): 6” Nominal Input Pressure (W.C.
Preparing for Installation Before beginning assembly or operation of the product, make sure all parts are present. Compare parts with package contents list and diagram above. If any part is missing or damaged, do not attempt to assemble, install or operate the product. Contact customer service for replacement parts.
UNPACKING 1. Remove heater from carton. 2. Remove all protective packaging applied to heater for shipping. 3. Check heater for any shipping damage. If heater is damaged, promptly inform dealer where you purchased heater. 4. Remove thread protective cup on the gas inlet pipe underneath the heater. 5. Install a D size battery. Be sure battery has full capacity. Battery must be removed if the heater is not in use for an extended period of time.
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 ensure proper fresh air for this and other fuel-burning appliances in your home. space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air.
DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION 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 door less passageways or ventilation grills between the rooms. 1. Determine the Volume of space in cubic feet Length X Width X Height = ___________________ cu. Ft. (Including adjoining rooms with door less passageways or ventilation grills between rooms) Example: 24’ (L) X 16’ (W) 8’ (H) = 3,072 cu.
WARNING: If the area in which the heater may be operated does not meet the required volume for indoor combustion air, combustion and ventilation air shall be provided by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes. Ventilation Air from Inside Building This fresh air would come from an adjoining unconfined space.
INSTALLATION CONSIDERATIONS This heater is intended for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source. WARNING: A qualified service person must install heater.
If Using Mantel You must have noncombustible material(s) such as slate, marble, tile, etc. At least ½ in. thick. With sheet metal you must have noncombustible material behind it. Noncombustible material must extend at least 8 inches up. If noncombustible material is less than 12 inches. you must install the fireplace hood accessory. Even if noncombustible material is more than 12 inches, you may need the hood accessory to deflect heat away from mantel shelf. See Figure 6, 7 and 8.
Installing Damper Clamp Remove all ashes or other debris from the fireplace. If the fireplace is equipped with an ash dump, be sure to seal the door with furnace cement or high temperature silicone. Be sure to check the damper for proper operation and verify that the flue passageway is open. Place the clamp over the lip of the damper and tighten the hold down bolt until the clamp is securely attached to the damper. This will prevent the damper from accidentally closing.
Air Door Setting the Air Door to the appropriate gas type being supplied to the log set is important, as it improves the color and appearance of the flame. The Air Door is located on the bottom of the log set heater. So, you will need to flip it over. I recommend laying a cloth down so that the metal of the burner does not rub on the floor. You will want to look for an oval shaped cover that has two screws.
Loosen this screw. Then, with your screwdriver still contacting the screw, slide/rotate the cylinder towards the NG (Natural Gas) side until it cannot slide any further. Once done, you will tighten the screw on the cylinder, then seal the air shutter cover again. For more information please visit our website www.thermablaster.com.

Log Placement Ensure that your heater’s logs are placed as shown below. It’s important that your logs do not cover burner holes, as this can lead to sooting and an overall drop in the performance of your heater. Logs should be placed sequentially, from lowest to highest, as the numbering indicates. There are grooves on many of the logs that allow for simple placement and help to prevent the logs from shifting positions.

CONNECTING TO GAS SUPPLY WARNING: A qualified service technician must connect heater to gas supply. Follow the heater specification and all local codes. Wrong gas supply may result improper operation, or damage on your heater, property or/and personal body. WARNING: This appliance requires a 3/8-inch UNF (Unified National Fine) inlet connection to the pressure regulator. External regulator Propane/LP supply tank WARNING: Never connect heater to private (non-utility) gas wells.
CAUTION: Two gas lines installation at the same time is forbidden. Do not the open cover while the heater is running. CAUTION: To avoid gas leakage at the inlet of appliance regulator, a qualified installer or service technician must use steel or metal hex plug with sealant.
UNIT OPERATION FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. 1. When lighting the pilot, follow these instructions exactly. 2. BEFORE LIGHTING, 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. 3. Use only your hand to push in or turn the gas control knob. Never use tools.
Ignition Process: 1. During the first seasonal operation, set the Control Knob to Pilot, then hold down on the Control Knob for 3-5 minutes. This allows the air in the manifests to clear completely. During normal operation, you will only need to hold the Control Knob down on Pilot for about 5 seconds. 2. With the Control Knob set to Pilot, push down on both the Igniter Button and the Control Knob simultaneously until ignition can be heard.

CARE AND MAINTENANCE WARNING: Turn off heater and let cool before servicing CAUTION: You must keep control areas, burner, and circulating air passageways of the heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service technician. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc. ODS/PILOT AND BURNER Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean.
TROUBLESHOOTING WARNING: If you smell gas: Open the window and door immediately. Shut off gas supply. Do not try to light any appliance. Do not touch any electrical switch; do not use any phone in your building. Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. If you cannot reach your gas supplier, call the fire department. IMPORTANT: Operating heater where impurities in air exist may create odors.
