GENERAL INFORMATION

• When the heater is cold or at room temperature, it will take a few minutes for the burner tile to turn bright orange. This is normal and the heater is working properly. If burner tile is visibly flaming, turn heater off and call a qualified service technician.
• When the unit is lit, there should be about a quarter inch (1/4”) border around the tile that will not turn bright orange. This is normal.
• When operating the heater for the first time, the top area of the reflector may discolor. This is also normal and is no reason for concern.

• Heater is designed to operate at altitudes up to 7,000 feet. When operating the heater at altitudes over 7,000 FT. above sea level, the unit may not burn as bright as in lower altitudes. This is normal. At higher altitudes, the heater may shut-off. If this happens, provide fresh air, wait 5 minutes and re-light. If the heater continues to shut off, there may not
  be enough oxygen available to feed proper combustion.

• Operating time will be approximately 5 1/2 hours on a one 1lb. cylinder. Due to the properties of LP gas, runtimes can be significantly reduced when operating continuously at temperatures below 20ºF.

• This heater is equipped with a tip-over safety switch. Nuisance shut-downs may be experienced if the unit is bumped or moved. if this occurs simply relight the heater.

• Due to natural operation of small tanks, condensation may build up on tank and drip on surface under heater. Sometimes this condensation may freeze due to the extreme cold caused when propane vaporizes. This is normal and no reason for alarm.

Lighting Instructions

ALWAYS ATTACH OR DETACH CYLINDER OUTDOORS AWAY FROM FLAMES, OTHER IGNITION SOURCES, AND ONLY WHEN HEATER IS COOL TO TOUCH. NEVER SMOKE WHEN ATTACHING OR REMOVING PROPANE CYLINDER!

• LP cylinders must be marked in accordance with “Cylinders, Spheres and Tubes for Transporation of Dangerous Goods, CAN/CSA B339”.

• Use only LP-gas cylinders marked in accordance with the U.S. Dept. of Transportation (DOT).

• Use only 16.4 oz. (1 lb.) disposable cylinders that mate with No. 600 valve connection.

• Heater and attached cylinder must be in an upright position during operation.

  1. Screw 1 lb. disposable LP-gas supply cylinder clockwise (from bottom) into portable heater until hand-tight and fit
     cylinder into stand. Do not use thread sealant on this connection. Be sure cup adapter fits tightly into cup holder before moving.

  2. Check cylinder connection for leaks with soapy water at the threaded connection under the domed plastic cover where the cylinder screws into the regulator. SEE WARNING! ON PLASTIC COVER.

  3. Depress “ON” button to light pilot flame (repeat until pilot lights) and continue to hold for 30-60 seconds.

  4. After lighting pilot, release “ON” button to light heater. The white tile will take a few moments to start to glow.

Shutdown Instructions

1. To shut off heater, press the “OFF” button.
   • Do not operate, store or remove cylinder near flammable items or ignition sources.
   • LP-GAS CYLINDERS MUST BE DISCONNECTED FROM HEATER WHEN NOT IN USE!

Maintenance

• Always keep the heater area clear and free from combustible materials, gasoline and other flammable vapors and liquids.
• Keep the vent areas (slots in the bottom and top of the heater) clear at all times.
• Visually inspect the pilot flame and burner periodically during use. The pilot flame should be blue in color (not yellow) and will extend to the thermocouple. The flame will surround the thermocouple just below the tip, see Figure 1.
• A slight yellow flame may occur where the pilot flame and main burner flame meet. The burner should be bright orange (with a slight blue color around the border, a red-orange haze that is visible on the ceramic tile is acceptable) and without a noticeable flame.
• A blue flame that rolls out at the top of the ceramic tile indicates an accumulation of dust, lint or spider webs inside the housing assembly and main burner assembly. If the pilot is yellow or the burner has a noticeable flame, cleaning may be required. Use the following procedure to inspect the casing assembly and main burner assembly. It is necessary to periodically check the burner orifice and burner venturi to make sure that they are clear of things such as insect nests and spider webs that may accumulate over time. A clogged tube can lead to a fire.

Cleaning Instructions (Refer to Exploded Parts on Page 6):

IMPORTANT : Allow heater to thoroughly cool before performing any maintenance.

1. Remove disposable 1 lb. propane cylinder from heater.

2. Remove right side plastic service panel (ref.4) by removing the six screws holding it in place.

3. Inspect the interior of casing for accumulation of dust, lint or spider webs. If necessary, clean the interior of the casing assembly with a vacuum cleaner or compressed air (max 30 psi). Do not damage any components within the casing assembly when you are cleaning.

4. Inspect and clean main burner (ref. 3) and orifice (ref. 8) by using a vacuum or compressed air (max 30 psi).

5. Inspect and clean pilot tube (ref. 7). Insert a doubled over pipe cleaner into the pilot tube until it bottoms against the pilot orifice (approximately 2”). Rotate the pipe cleaner a couple of times and remove. Blow out the remaining debris using compressed air.   WARNING : Always inspect propane cylinder and heater propane connections for damage, dirt, and debris before attaching propane cylinder. Do not use if head of cylinder is damaged, punctured or deteriorated.
   WARNING : Heater must not be exposed to flammable vapors or liquids during ignition or operation.
   CAUTION : After turning heater off, wire guard will remain hot. Allow to thoroughly cool before storing.
   WARNING : Never use needles, wires or similar cylindrical objects to clean the pilot to avoid damaging the calibrated ruby that controls the gas flow through the pilot orifice.

6. Apply compressed air (max 30 psi) into the ceramic tile of burner assembly and venturi tube (ref. 3) to remove dust, lint and spider webs.

7. Reinstall the right side plastic service panel.
