Patio Heater Glossary

Burner: Self contained unit to convert LPG gas into radiant heat with pole support fittings and reflector attached above.
Butane: Liquid petroleum gasoline fuel stored in steel cylinders varying in size from 7kg to 15kg. Highly flammable, colourless and odourless in natural state, an odourising agent is added. Operates via a regulator at 28mbar pressure.
BTU/h: British thermal units, official measurement of gas heat output for boilers and gas patio heaters. One BTU is the heat required to raise one pound of water one degree Fahrenheit.
CE: European conformity standard - legal requirement within European Union.
CSA: Canadian Safety Associations, legal requirement in Canada and USA.
Electromagnetic valve: A device inside the gas control valve to operate and open the seating and regulate the flow of gas.
Flame emitter screen: Casing surrounding the flame mantle manufactured in stainless steel with supports for the reflector bolts.
Gas knob: Plastic or metal knob attached to gas spindle, allows control of gas and lighting pilot.
Gas valve: Device located inside the burner to control flow of LPG gas, fitted with gas knob to turn on/off and high/low.
Ground fixers: Brackets to secure base to the ground.
Housing: Cylindrical cover to conceal the LPG gas cylinder. Normally manufactured in steel but can be resin compound.
Hammered steel: Bubble effect painted finish.
Hose: High pressure tube that is attached to a regulator and burner, to deliver LPG gas supply.
Ignitor lead: Insulated copper wire with needle to deliver electronic spark from piezo ignitor to ignite pilot.
Jubilee clip: Securing clips attached to each end of the hose to prevent gas leakage.
Leakage testing: Solution of washing up liquid and water applied to joints to reveal any possible leaks of LPG.
K. W.: Kilo watts used to measure electric energy consumption.
Mantle base: Stainless steel lower section of burner that contains the main gas parts and supports.
Patio heater: Outdoor heating device, can be fuelled by LPG gas, electric or fire pit using coal or wood.
Patio heater cover: PVC or canvas cover, can be shaped for fitted finish. Usually zipped for easy removal.
Post: Pole holding the burner and attached to support brackets.
Piezo ignitor: Manual or electronic device to create a short electric charge that travels via a ignitor lead to deliver a spark between the needle and thermocouple.
Pilot: Gas holding position to enable thermocouple sufficient time to heat up and open burner jets.
Propane: Liquid petroleum gasoline fuel stored in steel cylinders varying in size from 3.5kg to 47kg. Highly flammable, colourless and odourless in natural state, an odourising agent is added. Operates via a regulator at 37mbar pressure.
Reflector: Circular aluminium disk attached to burner, prime purpose to reflect radiant heat.
Reflector support bolts: Steel bolts connecting the flame emitter screen with the reflector.
Regulator: Device to control the flow of LPG to the gas control valve. Attaches to the LPG cylinder and hose with jubilee clips.
Support brackets: Steel brackets attached to base to hole the post in place, situated inside of housing.
Thermocouple: Device for controlling the heat emitter via the gas control valve. Thermoelectric gas valve used to control heat output.
Tilt switch: Device to cut off flow of gas when patio heater is tilted by 30 degrees.
Wing nuts: Threaded nuts attached to support bolts to hold reflector in place.
