Nearly all gas burning appliances require a regulator which reduces and controls the pressure from a cylinder of gas.
Most domestic appliances run at 'low pressure' which is between 28 and 37 mbar. Blowtorches and many industrial appliances run at high pressure - typically 1-2 bar (15-30 psi). In choosing a regulator you need to consider 3 things:
- which gas is being used - propane or butane
- what pressure is required for the appliance - this would then the the required outlet pressure for the regulator
- what is the flow of gas required by the appliance - you then need to ensure that the capacity of the regulator is high enough to supply this
Technical Data - High Pressure Regulators
Propane regulators Please note that these Bullfinch propane regulaotrs (like most UK propane regulators) have the 5/8"BSP LH male POL connector. In other countries a very similar connector is required but it with the USA 0.880" NGO LH male thread with the same raduised connection. These threads are very similar but not the same and it is important that the correct one is chosen.
Gas Supply Information - Low Pressure Appliances
Low pressure appliances - Type I3+ - requirements for gas supply
Where type I3+ low pressure appliances are referred to (butane at 28/29mbar or propane at 37 mbar), the following hoses, clips and regulators are suitable:
- No. 7026 for a butane cylinder with a 20mm clip on connection - 28 mbar or
- No. 7027 for a butane cylinder with a 21mm clip on connection - 28 mbar or
- No. 330 for a propane cylinder with a POL connection - 37 mbar or
- No. 7069 for a propane cylinder with a 27mm clip on connection - 37 mbar (eg Calor Patio Gas, or Flogas Leisure Propane Gas)
- No. 1314 or No.1319 - Hose - we would suggest at least 3m of 8mm bore hose
- Hose Clips
- No. 1306 Hose clips - 2 off
These products can also generally be used off a I3B/P supply which is propane or butane at 30mbar pressure. This is the supply in new caravans and in some other environments and means that they can be used from a Gas/Barbecue point - our No. 6087/01.
Always check the manufacturers' instructions before using any appliance.
