The Appliance Regulator controls the manifold pressure on Cata-Dyne™ heaters fuelled by natural gas. The Service or Low Pressure Regulator works with all Cata-Dyne™ heater models operating on LPG or natural gas. It serves as a natural gas low pressure line regulator when used in conjunction with the gas appliance regulator. The High Pressure Regulator has a similar function to the Low Pressure, but features much higher maximum inlet and outlet pressures, and is installed upstream of any other regulators provided.
