Gas Regulators

Adjusting a Bromic gas regulator ensures that gas-powered appliances receive the correct pressure for optimal performance. The process varies depending on the type of regulator (LPG, natural gas, single-stage, or dual-stage), but the general steps are similar.

1. Identify the Adjustment Screw
Locate the pressure adjustment screw on the regulator (typically covered by a plastic cap that needs to be unscrewed). Some Bromic regulators use spring-loaded mechanisms to control gas flow.

2. Turn On Gas & Test Appliance
Slowly open the gas supply and ignite the appliance.
Observe the flame pattern and appliance performance. A steady blue flame indicates proper adjustment.

3. Make Small Adjustments
While the appliance/s are running, measure the dynamic pressure and adjust as required.
Increase Pressure: Turn the screw clockwise (+) to allow more gas flow.
Decrease Pressure: Turn the screw counterclockwise (-) to reduce gas flow.
Adjust in ¼-turn increments, checking the pressure gauge after each adjustment.

5. Check for Gas Leaks
Mix soapy water or a leak detector such as LA-CO Visu-glow Fluorescent Leak and apply it to the regulator connections. If bubbles form, there is a leak – tighten connections or replace seals.

6. Secure the Adjustment & Monitor
Once the correct pressure is set, replace the adjustment cap (if applicable). Monitor the appliance over time to ensure consistent performance. 

1. High-Pressure Gas Enters the Regulator
Gas flows from the supply source (LPG cylinder or natural gas line) into the regulator.
This gas is at a much higher pressure than what appliances can handle.

2. Diaphragm & Spring Mechanism Adjusts Flow
Inside the regulator, a spring pushes against a diaphragm, keeping the valve partially closed.
When the outlet pressure drops, the spring opens the valve slightly, allowing more gas to flow.
As the pressure rises, the diaphragm pushes back, closing the valve to reduce flow.

3. Pressure Stabilization
The regulator constantly adjusts the valve opening to maintain a consistent outlet pressure despite fluctuations in the gas supply or appliance demand.
Some regulators have an adjustment screw that allows users to fine-tune the pressure.

4. Safety Venting (If needed)
If pressure builds up excessively, all regulators include a safety valve/vent to release small amounts of gas safely. Ensure this is free of obstruction at all times.
The plumber should check what safety features are required for the installation of each regulator. Additional safety valves can be installed if required – such as an OPSO Valve.

A gas regulator is a device that controls the pressure of gas flowing from a high-pressure source (such as a gas cylinder or supply line) to a lower, usable pressure for appliances. It ensures a consistent and safe gas flow, preventing overpressure that could damage equipment or cause safety hazards.

Yes, it has a nut on the top that can be taken off and a small flat head screwdriver can be screwed in to increase pressure. 

Yes, the product code is 6060586 and has 2 x 6SHW0450 instead of the 2 x 6LCC270450FLA.

Yes, the natural gas appliance regulators (item number: 6160788 and 6160785) can be installed in cupboards or outside for a BBQ.

When using the natural gas appliance regulators (item number 6160788 and 6160785) the vent is for air, not gas. (If gas can be smelt from this, there is a puncture in the diaphragm and must be replaced). The vent allows the diaphragm to move up and down to allow the gas to flow. Through the regulator. If this is blocked, the gas will either be blocked from flowing or will not be able to stop flowing depending on how the diaphragm is stuck. The yellow cap should be left on to prevent dust or insects from blocking the hole. 

The 250 MJ and 500 MJ manual dual stage regulator, 400 MJ auto dual stage regulator and 160MJ dual stage regulator kit are manufactured in Italy, by Cavagna.

No, they must be installed with the vent facing down as per the manual.
