  2. This outdoor heater is not intended to be installed on recreational vehicles and/or boats.

  3. Improper installation, adjustment, and alteration can cause personal injury or property damage.

  4. Do not attempt to alter the unit in any manner.

  5. Never replace or substitute the regulator with any regulator other than the factory-suggested replacement.

  6. Do not store or use gasoline or other flammable vapors or liquids in the heater unit.

  7. The whole gas system, hose, regulator, pilot, or burner should be inspected for leaks or damage before use, and at least annually by a qualified service person.

  8. All leak tests should be done with a soap solution. Never use an open flame to check for leaks. Do not use the heater until all connections have been leak tested.

  9. Turn off the gas valve immediately if the smell of gas is detected. Turn Cylinder Valve OFF. If the leak is at the Hose/Regulator connection: tighten the connection and perform another leak test. If bubbles continue appearing should be returned to the hose’s place of purchase. If the leak is at Regulator/Cylinder Valve connection: disconnect, reconnect, and perform another leak check. If you continue to see bubbles after several attempts, the cylinder valve is defective and should be returned to the cylinder’s place of purchase.

Heater position

The heater is primarily for outdoor use only. Always ensure that adequate fresh air ventilation is provided.
Always maintain proper clearance to combustible materials, i.e. top 100 cm and sides 100 cm minimum.
The heater must be placed on level firm ground.
Never operate the heater in an explosive atmosphere like in areas where gasoline or other flammable liquids or vapors are stored.

Gas requirements

This heater is primarily designed to be used with propane gas tanks.
Butane gas tanks may also be used with the appropriate regulator.
The installation and use of this appliance must correspond with local standards, or in the absence of local codes, with the standard for the storage and handling of liquid petroleum gases.
A dented, rusted, or damaged propane tank may be hazardous and should be checked by your tank supplier. Never use a propane tank with a damaged valve connection.
The propane tank must be arranged to provide for vapor withdrawal from the operating cylinder.
Never connect an unregulated propane tank to the heater.

Leakage test

Gas connections on the heater are leak tested at the factory prior to shipment. A complete gas tightness check must be performed at the installation site due to possible mishandling in shipment or excessive pressure being applied to the heater.

  • Make a soap solution of one part liquid detergent and one part water. The soap solution can be applied with a spray bottle, brush, or rag. Soap bubbles will appear in case of a leak.

  • The heater must be checked with a full cylinder.

  • Make sure the safety control valve is in the OFF position.

  • Turn the gas supply ON.

  • In case of a leak, turn off the gas supply. Tighten any leaking fittings, then turn the gas supply on and recheck.

  • Never leak test while smoking.

Use and storage

To turn on:
Warning: Please ensure the glass tube has not been damaged during transportation.

  1. Make sure the variable control knob is in the OFF position.
  2. Connect the gas regulator to a compatible gas cylinder.
  3. Push and turn the variable control knob to the PILOT position and hold it for 60 seconds. Whilst still holding the control knob down, press the ignition button – a pilot flame should appear.
  4. Once the blue pilot flame stays lit up constantly, let go of the variable knob.
  5. Turn the variable control knob to the desired temperature position.
    • When lighting the heater on for the first time or an after a new cylinder was connected, the air inside the hose must be purged. This process will take a few minutes as liquefied petroleum gas is heavier than air.
    • To do so, press the variable control knob down in the PILOT position for about 3 minutes.

To turn off:

  1. Turn the variable control knob to the PILOT position.
  2. Press and turn it to the OFF position.
  3. Turn the regulator connected to the gas cylinder to the OFF position.

Storage

  • Always turn the regulator connected to the gas cylinder to the OFF position after each use.
  • Disconnect the regulator from the cylinder if the heater is not in use.
  • Never store the gas cylinder indoors or without adequate air ventilation.

Cleaning and care

  • Wipe off surfaces with a soft, moist cloth. Do not clean the heater with cleaning products that are combustible or corrosive.
  • Remove debris and insects from the burner periodically to keep it clean and safe for use.
  • Cover the burner unit with a protective cover when the heater is not in use.

Construction and characteristics
