Gas Regulator NZ: LPG Regulator & LPG Gas Bottle Regulator – BBQ Gas Regulator and Hose
The primary function of a gas regulator NZ (LPG regulator) is as a high pressure LPG gas regulator to reduce the gas regulator pressure to safe operating levels.
Inside an LPG bottle, LPG bottle pressure could range from 400 to 1200kPa.
The LPG gas bottle regulator or 45kg gas bottle regulator (gas regulator), connected by a gas hose or gas pigtail, drops that to 2.75kPa gas regulator pressure, the standard low pressure gas required by LPG gas pressure regulator specifications.
In real-world scenarios, the LPG bottle pressure in the gas bottle could vary with temperature, particularly if it’s located outdoors.
Regardless, the LPG gas regulator (gas regulator NZ) must consistently maintain a low pressure gas output of 2.75kPa gas regulator pressure.
Common gas regulator NZ (LPG regulator) types used include LPG gas regulator, 45kg gas bottle regulator, acetylene gas regulator, and oxygen gas regulator.
In addition to the type of gas passing through them, gas regulators also vary by design and gas fittings.
How Does an LPG Regulator (Gas Regulator) Work?
From the LPG bottle pressure, gas enters the LPG regulator (gas regulator NZ) through the inlet port, via a gas hose or gas pigtail, and the gas regulator pressure is controlled by a spring-loaded diaphragm.
The LPG regulator (gas regulator) works as the diaphragm actuates when pressure changes and adjusts the inlet valve accordingly to produce a consistent output gas regulator pressure.
An LPG regulator (gas regulator) is essential to your LPG system for safe energy use in your home, business, BBQ, caravan, or motorhome.
The LPG bottle pressure within an LPG gas bottle can be 400-1200 kPa vs the low pressure gas 2.75 kPa gas regulator pressure typically required by LPG gas pressure regulator specifications.
An LPG regulator (gas regulator) works to automatically reduce LPG bottle pressure to this required gas regulator pressure (low pressure gas).

LPG is Stored Under Pressure
LPG is stored under pressure as a liquid in a gas bottle.
It turns back into a gas when you release some of the pressure in the gas bottle by turning on your appliance.
The LPG bottle pressure within a gas bottle can be 800-900kPa.
This varies based on the ambient temperature and exposure to the radiant heat of the sun.
LPG Regulator Types: BBQ Gas Bottle Regulator & 45kg Gas Bottle Regulator
LPG regulator, BBQ gas bottle regulator (BBQ pressure regulator) or 45kg gas bottle regulator (gas regulator) types & sizes vary depending on the gas load.
Although the purpose of gas regulators is the same, different gas load applications may require different LPG regulator types and sizes, like a 45kg gas bottle regulator or BBQ gas bottle regulator (LPG gas regulator).
The appliance’s gas demand determines the type of LPG regulator (gas regulator NZ) that is installed.
For example, if your home’s appliances’ combined megajoule (MJ) rating is quite high, an LPG regulator with a higher MJ rating size would be required, like a 45kg gas bottle regulator.
Commercial-sized LPG regulator (gas regulator) are completely different and frequently include two separate gas regulator units, gas hose (gas pigtail) and gas fittings.
Please note that a BBQ gas regulator should never be used on a home installation.
LPG Regulator Problems – BBQ Gas Regulator
LPG gas, with gas regulators, is a widely used fuel in NZ households and businesses.
But what if your BBQ grill isn’t heating properly or the flame is too low and ineffective?
BBQ gas regulator problems are typically the result of a damaged BBQ gas regulator (gas regulator) and is the most common cause of heating and operation problems.
Possible LPG regulator problems include:
1. Low temperature or low flame
This will limit the amount of LPG fuel feeding your burners and not provide the desired grilling temperature.
This is more typically a clogged gas jet in the burner rather than a BBQ gas regulator (gas regulator NZ) problem.
2. The grill isn’t receiving gas
If your tank is full and your grill isn’t receiving any gas, it might indicate BBQ gas regulator (gas regulator) problems. So, replace the BBQ gas regulator and hose assembly or contact your gas fitter for service.
You can contact our emergency LPG technicians at 0800 435 427 to promptly address any safety issue and avoid unwanted incidents and safety hazards.
3. The LPG regulator connection has frozen
As LPG gas vapour passes through the LPG regulator (gas regulator NZ), it expands from high to low pressure gas, reaching sub-zero temperatures.
In NZ, where temperature and humidity can significantly vary, the expansion process may cause condensation, frost or ice to form on the BBQ gas regulator and/or freeze the LPG regulator body.
Usually, the freezing should only occur on the outside of the gas hose (pipe) and not inside them.
But if you suspect that a frozen LPG regulator (gas regulator) causes the LPG gas regulator problems, contact your gas fitter right away.
4. Orange or yellow flame
Check the valve and gas hose and especially the gas jets in the burner.
LPG regulator (gas regulator NZ) components may need replacing. Once again, contact your gas fitter.
If you notice your gas stove producing yellow or orange flames when used, it could be that the combustion isn’t getting enough oxygen due to clogged LPG gas fittings.
Remember that a yellow flame is also a sign of carbon monoxide in the combustion, a highly toxic fume when inhaled.
Stop using the stove immediately and contact your gas fitter or our emergency team at 0800 435 427 to have it inspected and fixed.
45kg Gas Bottle Regulator, Gas Changeover Valve Problems & Fittings
Gas bottle fittings and couplings include the 45kg LPG gas bottle regulator (gas regulator), gas bottle pigtails, gas hose (piping), connectors, gas bottle changeover valve, and gas fittings.
Gas fittings called LPG gas pigtail or copper gas pigtails are flexible gas hose fittings that connect the gas bottle to the gas bottle changeover valve or directly to the 45kg gas bottle regulator.
The gas to the LPG gas pressure regulator (gas regulator NZ) typically comes from the gas bottle changeover valve, which determines the gas bottle used.
Gas Pigtail, Gas Hose, POL Gas Fitting & LPG Gas Fittings NZ
Home gas bottles are connected by LPG gas fittings NZ, including a gas pigtail (flexible pipe or gas hose) to a gas bottle changeover valve, which is connected to the LPG regulator (gas regulator NZ) with POL gas fittings.
A gas pigtail can be copper gas pigtails, rubber (gas hose), or braided metal over a rubber gas hose interior and a POL gas fitting on the end.
Copper gas pigtails are generally considered the best choice for LPG gas fittings NZ, as a rubber gas hose and braided gas pigtail have a limited life span.
Without a flexible gas pigtail, a rigid gas hose would be more susceptible to cracking and leaks.
A portable gas heater can be connected to your home LPG supply using a gas bayonet fitting.
The male gas bayonet connector on the end of the heater gas bayonet hose plugs into the female gas bayonet connector.
If you need a new full gas bottle from ELGAS for your home or business in NZ, call us at 0800 435 427.
Order a replacement gas bottle when the first bottle runs out and you will never run out of gas.
Gas Bayonet Fittings
If you have a portable gas heater, it will be connected to your home LPG supplied using gas bayonet fittings.
Gas bayonet fittings can be floor or wall mounted.
The male gas bayonet connector, on the end of the heater gas bayonet hose, plugs into the female gas bayonet connector which is, in turn, connected to the LPG service piping.

How to Connect & Disconnect Gas Bayonet Fittings
LPG Gas Pipe
A gas pipe runs from the LPG regulator (gas regulator NZ) to your appliances.
This LPG gas fittings NZ is the service gas pipe.
LPG gas fittings NZ (gas pipe) generally consists of copper gas pipe or plastic polyethylene gas pipe.
The gas pipe must be installed correctly and legally by a qualified professional gas fitter for the installation to be safe and serviceable.
BBQ Gas Bottle Regulator & BBQ Gas Fittings
BBQ gas bottle regulator fittings (BBQ gas fittings) involve fewer components than home installations.
Typical BBQ gas regulator fittings include a QCC BBQ gas regulator with BBQ gas fittings, gas hose, and connector.
The QCC BBQ gas regulator (gas regulator NZ), gas hose, and connector usually come as an assembly, but a gas hose is also sold separately.
How to Change a BBQ Gas Regulator – Change a BBQ Gas Bottle
To remove the BBQ gas bottle regulator (BBQ gas regulator), make sure the gas bottle is turned off by turning clockwise firmly.
Unscrew the BBQ gas regulator by turning the handwheel anti-clockwise.
1. To change (attach) a BBQ gas regulator (change a BBQ gas bottle), place the full gas bottle on the BBQ mounting hook or in its holder/shelf, depending on your BBQ or heater.
The BBQ gas bottle should ALWAYS be kept upright.
Your LPG gas bottle must NEVER hang by the gas hose.
2. Remove any dust cover or plug that may be inside or over the female valve opening on the full BBQ gas bottle, where the BBQ gas regulator screws in.
Please note that, if it is a screwed-on plug, you must turn it anti-clockwise to remove it.
3. Inspect the BBQ gas hose and gas regulator for any damage.
The gas hose can perish over time.
Some BBQ gas regulator types have rubber O-rings on the connector.
The O-ring should also be undamaged.
The connector should be clean and dirt free prior to insertion.
4. Screw the BBQ gas regulator into the valve opening by turning BBQ gas regulator hand wheel clockwise.
Tighten well by hand only.
Make sure the gas hose is not kinked.
5. When you change a gas regulator (connect a BBQ gas bottle), you should do a leak test.
Without turning on the BBQ, open the gas valve hand wheel to turn on the gas (anti-clockwise).
Spray all the gas fittings and BBQ gas regulator (gas regulator), valve and gas hose with soapy water to check for any possible leaks.
You will see bubbles or smell gas if there is a leak.
If you have a leak, you should immediately turn the gas off (clockwise) and fix or replace the leaking component.
6. Assuming you have no leaks, you are ready to use your BBQ or other gas appliance.
Turning the BBQ gas bottle ON a couple of turns is sufficient.
You should not turn it hard to the open stop.
7. Remember, when you are finished with your BBQ, gas heater, or other gas appliance, you should always turn off the gas at the BBQ gas bottle first.
Close clockwise firmly by hand only.
