Mobile & Rural Expertise
Specialists in food truck, caravan, RV, and off-grid rural property LPG installations. We understand mobile application requirements, council compliance for commercial vehicles, and remote property energy independence solutions.
Appliance Conversion
Convert existing natural gas appliances to LPG using manufacturer-approved conversion kits. We replace burner jets, adjust regulators, recalibrate flame settings, and certify converted appliances for safe LPG operation.
Supplier Coordination
After installation, we connect you with reliable LPG suppliers for cylinder purchase or rental, arrange delivery schedules, and provide guidance on refill options—ensuring your ongoing energy supply is seamless and cost-effective.
Cylinder Configurations For Every Application
From portable bottles to permanent bulk tanks—we install the right LPG system for your needs
Single Cylinder Systems
Ideal for caravans, small cabins, BBQ setups, and temporary applications. We install 9kg, 15kg, or 45kg cylinders with appropriate regulators, secure mounting brackets, and compliant pipework. Perfect for seasonal use or backup energy supply with straightforward bottle exchanges.
Dual Cylinder With Changeover
Two-bottle systems with automatic changeover valves ensure uninterrupted LPG supply. When one cylinder empties, the system automatically switches to the reserve bottle and signals for refill. Ideal for homes, holiday properties, and permanent installations requiring continuous supply.
Manifold Multi-Cylinder Systems
Commercial and high-demand applications benefit from manifold systems connecting 3–8 cylinders. Restaurants, food trucks, industrial heating, and large properties use manifold setups for extended runtime between refills. Includes automatic switchover and low-gas alarms.
Bulk LPG Tanks (90kg–210kg+)
Permanent bulk tanks provide the most economical LPG supply for rural homes and commercial properties. Installed above-ground or underground with supplier refill access. Capacity from 90kg to multi-tonne installations. Ideal for whole-house heating, cooking, and hot water in off-grid locations.
Mobile & Portable Setups
Food trucks, catering vans, market stalls, and event equipment require certified mobile LPG installations. We install quick-disconnect fittings, vibration-resistant brackets, compliant hose assemblies, and provide documentation for council permits and health department approvals.
Caravan & RV Systems
Recreational vehicles need lightweight, compact LPG systems with dual-appliance capability (cooking and heating). We install gas lockers, external cylinder mounts, internal pipework, regulator upgrades, and safety shutoffs that comply with caravan certification requirements.
Why Choose LPG Over Natural Gas?
LPG offers unique advantages for properties and applications where natural gas isn't available or practical
Available Anywhere
LPG doesn't require pipeline connection, making it ideal for rural properties, off-grid homes, remote locations, and areas where natural gas infrastructure doesn't exist. Cylinders can be delivered and installed anywhere in Sydney and regional NSW.
Portable & Mobile
LPG cylinders enable energy supply for mobile applications including caravans, RVs, boats, food trucks, market stalls, temporary event setups, and construction sites. Quick disconnects allow easy bottle changes and portability between locations.
Higher Energy Density
LPG contains approximately 2.5 times more energy per cubic metre than natural gas, resulting in hotter flame temperatures and more efficient appliance performance—particularly beneficial for commercial cooking and outdoor heating applications.
No Connection Fees
Unlike natural gas which requires expensive pipeline connection and meter installation (often $2,000–$5,000+), LPG cylinder systems have minimal upfront infrastructure costs. Pay only for installation and gas consumption without ongoing connection charges.
Energy Independence
LPG provides energy security independent of grid infrastructure. Ideal for bushfire-prone areas where natural gas may be shut off during emergency periods, or for properties seeking self-sufficiency with solar + LPG hybrid systems.
Quick Installation
LPG systems can be installed and commissioned within 1–2 days (depending on complexity), compared to weeks or months waiting for natural gas connection approval and infrastructure installation from network providers.
Flexible Scalability
Start with a small single-cylinder system and easily expand to dual bottles, manifold configurations, or bulk tanks as your energy needs grow. Add cylinders or upgrade capacity without major infrastructure changes or approvals.
Backup Energy Option
Many homes use LPG as a backup to natural gas or electricity, ensuring continued operation of critical appliances (cooking, heating, hot water) during power outages or gas supply interruptions—essential for aged care, medical equipment, and business continuity.
Choosing The Right LPG Cylinder Size
Match your cylinder capacity to appliance load and refill frequency preferences
9kg Cylinder
15kg Cylinder
45kg Cylinder
90kg Cylinder
210kg Cylinder
Bulk Tanks (500kg+)
Usage Calculation Guidelines
Cooking Only: Average household uses 10–15kg LPG per month (dual 45kg cylinders provide 5–7 months supply)
Cooking + Hot Water: Increase to 20–30kg per month (dual 45kg cylinders provide 2–4 months)
Cooking + Hot Water + Heating: Winter consumption can reach 40–60kg per month (90kg or bulk tank recommended)
Commercial/Food Truck: Heavy daily use requires 15–25kg per week (manifold system or weekly bottle exchanges)
Our team calculates appliance load and recommends appropriate cylinder size and configuration during site assessment.
Professional LPG System Installation In 8 Steps
From site assessment to certification—we handle every aspect of your LPG installation
Site Assessment & Design
Our licensed gas fitter visits your property to assess appliance requirements, location constraints, ventilation conditions, and compliance factors. We calculate total gas load (in MJ/hr), determine appropriate cylinder size and quantity, and design the system layout including cylinder placement, pipework routes, and regulator specifications. For food trucks and mobile applications, we review council requirements and provide compliance advice.
Cylinder Placement & Mounting
Cylinders must be located outdoors in well-ventilated areas with specific clearance distances from ignition sources, windows, doors, and property boundaries. We install compliant cylinder stands, wall brackets, or protective cages ensuring secure mounting and protection from vehicle damage. Placement considers refill access, changeover convenience, and protection from weather exposure. Underground bulk tanks require excavation and concrete pad installation.
Regulator & Changeover Valve Setup
First-stage regulators reduce cylinder pressure (800–900 kPa) to low pressure (2.75 kPa) suitable for appliances. Dual-cylinder systems include automatic changeover valves that switch to the reserve bottle when primary empties, with indicator flags signaling refill requirements. We install weather-protected regulator housings, secure all connections with approved fittings, and verify correct pressure delivery throughout the system.
Gas Pipework Installation
We run copper tube or flexible TracPipe from cylinder location to appliances, ensuring pipework is properly sized for gas flow requirements and distance. External pipework is UV-protected and secured with appropriate brackets at regulation spacing. Underground lines are installed in protective conduit with tracer wire. All penetrations through walls or floors are sealed and sleeved to prevent moisture ingress and rodent damage.
Appliance Connection & Conversion
If converting appliances from natural gas to LPG, we replace burner jets with LPG-specific orifices, adjust pressure regulators, and recalibrate flame settings per manufacturer specifications. New LPG appliances are connected with isolation valves and tested for correct operation. BBQs, heaters, cooktops, ovens, and hot water units are commissioned individually with flame pattern inspection and safety feature verification.
Pressure Testing & Leak Detection
Before commissioning, the entire system undergoes nitrogen pressure testing at 1.5× operating pressure for minimum 15 minutes to verify integrity of all connections and pipework. We conduct electronic leak detection and soap-bubble testing on every joint, valve, and appliance connection. Any leaks are rectified immediately and retested until zero-tolerance compliance is achieved.
System Commissioning & Safety Checks
With cylinders connected and charged, we purge air from pipework, light and adjust each appliance, verify correct flame characteristics, test automatic changeover operation (if fitted), check overpressure protection, and ensure all isolation valves function correctly. Emergency shut-off procedures are explained and documented. For commercial installations, we coordinate final inspections with certifying authorities.
Certification & Documentation
Every LPG installation receives a Certificate of Compliance (Form 4) lodged with NSW Fair Trading and provided to you for insurance and property records. We supply operation manuals, appliance conversion documentation (if applicable), changeover instructions, emergency contact details, and LPG supplier information. For commercial and food truck installations, additional council and health department certificates are prepared as required.

LPG Safety Regulations & Best Practices
Understanding cylinder placement, changeover procedures, and emergency protocols
Cylinder Placement Rules
LPG cylinders must be located outdoors in well-ventilated areas. Never install in enclosed spaces, basements, or areas where leaked gas could accumulate.
Minimum 1 metre horizontal clearance from windows, doors, vents, air conditioning units, and other openings. Minimum 3 metres from ignition sources like pilot lights, electrical switchboards.
Cylinders must be protected from vehicle impact using bollards, protective cages, or location away from traffic areas. Consider vandalism protection for accessible public areas.
Install on concrete pad, pavers, or metal stands—never on grass, dirt, or combustible decking. Ensure surface is level to prevent regulator malfunction and safe cylinder orientation.
LPG is heavier than air and accumulates in low points. Avoid depressions, pits, or below-grade locations. Ensure natural cross-ventilation prevents gas pooling.
Display "LPG—No Smoking—No Naked Flames" signs at cylinder location. Mark emergency isolation valve positions clearly for quick identification.
Changeover & Maintenance
Dual-cylinder systems automatically switch to reserve when primary empties. Red/green indicator flags show which cylinder is in use. Replace empty cylinder promptly to maintain backup supply.
1. Turn off isolation valve at empty cylinder. 2. Disconnect regulator or pigtail. 3. Remove empty cylinder. 4. Install full cylinder upright and secure. 5. Connect regulator (hand-tight plus ½ turn with spanner). 6. Soap-test connection before opening valve. 7. Open valve slowly.
After every cylinder change, test connections with soapy water solution (never flame). Bubbles indicate leak—retighten or replace washer if leak persists. Commercial operations should maintain electronic leak detector.
Licensed gas fitter should inspect regulators, hoses, pipework, and appliances annually. Check for corrosion, damage, UV degradation, insect nests, and pressure regulation accuracy. Replace hoses every 5 years minimum.
LPG cylinders require 10-year recertification testing. Suppliers track certification dates—expired cylinders won't be refilled. We coordinate recertification during routine service visits.
LPG vaporization slows in cold weather. Keep cylinders in sunny locations, use vapour-withdrawal cylinders for high-demand applications, and consider cylinder heaters for commercial operations requiring consistent flow in winter.
Emergency Shut-Off Procedures
1. Extinguish all flames immediately. 2. Turn off cylinder valve at bottle. 3. Turn off appliances. 4. Ventilate area—open windows and doors. 5. Do NOT operate electrical switches, phones, or ignition sources. 6. Call gas fitter or emergency services from outside property.
Know location of: 1. Main cylinder isolation valve (at bottle). 2. Appliance isolation valves (near each appliance). 3. Emergency master shutoff (if fitted). Tag valves for quick identification during emergencies.
If fire involves LPG cylinders, evacuate immediately and call Fire & Rescue NSW (000). Do NOT attempt to fight LPG cylinder fires—risk of explosion. Inform responders of cylinder location and size.
Panther Plumbing Group provides 24/7 emergency gas service. If you cannot safely isolate LPG leak or require urgent gas fitting repairs, call 0404 939 121 anytime for immediate licensed assistance.
LPG Supplier Coordination
You can purchase cylinders outright (~$150–$300 depending on size) or rent from suppliers like Elgas, Kleenheat, Origin, Supagas ($30–$50/year rental). Owned cylinders can be refilled anywhere; rental cylinders locked to specific supplier.
Bottle exchange at service stations (~$35–$160 depending on size) is convenient but you only receive ~80% fill. Direct refill at LPG suppliers or scheduled home delivery provides full cylinder capacity and better value for permanent installations.
Large bulk tanks (90kg+) are refilled by tanker truck—suppliers schedule regular deliveries or use telemetry monitoring to automatically dispatch when tanks reach 20% capacity. Rates negotiable based on volume.
After installation, we connect you with reliable LPG suppliers servicing your area and help set up delivery accounts. For commercial clients, we can negotiate bulk pricing and priority service agreements with major suppliers.
