Can I connect my BBQ to my caravan’s bayonet gas outlet in Australia?
Table of Contents
Last updated: 6 Feb 2026
Answer (TL;DR): Yes... sometimes. If you plug a BBQ into a caravan’s bayonet (quick-connect) outlet, it’s treated like part of the caravan’s gas installation. That’s why your BBQ should have built-in flame failure protection on all burners and be used with correct isolation and safe fitment. This guide explains what to look for and why Sizzler is caravan-ready.
Safety & compliance note (Australia)
- Always follow the data label and manufacturer instructions on your BBQ and caravan.
- If connecting to a reticulated gas supply (bayonet fitting), guidance commonly requires a BBQ to be fitted with a Flame Failure Device (thermocouple/“thermo coupler” style). (Information only, always get licensed advice for your setup.)
- Any modification to caravan gas systems should be completed and checked by a licensed gas fitter.
Quick comparison: Caravan BBQs we sell (built-in thermocouple flame failure)
These two are the options we currently stock for bayonet-ready caravan setups, with built-in flame failure on both burners (thermocouple-based).

Why the caravan bayonet outlet is different to “BBQ on a bottle”
At first glance, a bayonet outlet looks like a convenience feature: one click and you’re cooking. The important detail is that a bayonet outlet is part of the caravan’s reticulated gas supply; so when a BBQ connects to it, it’s treated more like an installed appliance than a backyard portable. That’s why safety features and correct setup matter more than “it lights up”.
What “flame failure” actually means in real life
Flame failure protection is designed to shut off gas if the flame goes out unexpectedly. In caravan use (wind, movement, different cooking positions), it’s a key safety feature; especially when connected to a bayonet/quick-connect supply. On Sizzler models, this safety feature is built into the control system using thermocouples (often described as a “Thermo Coupler”).
Why Sizzler BBQs are a popular caravan choice
Sizzler BBQs are built around caravan constraints: compact footprints, strong output for fast preheat, and fitment options like slide systems for tunnel boots and generator boxes. The big difference is that flame failure is built in on both burners—so you’re starting from a caravan-ready appliance rather than trying to adapt a backyard BBQ to a bayonet outlet.
A quick “before you buy” checklist
- Will you use the bayonet outlet? If yes, make flame failure non-negotiable.
- Measure your tunnel boot opening (not just the floor space).
- Plan a safe slide-out distance and heat clearance.
- Decide whether you want a deeper cook surface (MAX) or a lighter unit (Deluxe).
- Have a licensed gas fitter review the final setup if you’re installing or modifying anything.

FAQ
Can I plug any BBQ into my caravan’s bayonet outlet?
No. A BBQ that connects to a bayonet outlet is commonly treated like part of the caravan’s gas installation, so it should have built-in safety features (especially flame failure) and be used with correct isolation and fitment. Not doing so is now against the law in Australia, can lead to insurance denial and possibly serious injury or death. If in any doubt, always contact a licenced gas fitter for expert advice!
Do the Sizzler Deluxe 2.0 and Sizzler MAX have flame failure built in?
Yes. Both models include flame failure devices on both burners, achieved via thermocouple (“Thermo Coupler”) style shut-off protection.
Is flame failure something I can add later?
Usually, flame failure is integrated into the BBQ’s gas control system and isn’t a universal add-on. If you’re unsure, choose a model that includes it from the start.
Do I need a gas fitter to set this up?
If you’re installing a slide system, fitting a bayonet connection, or changing anything in the caravan gas system, a licensed gas fitter should handle the work and checks. However, if the fitting is already there you can safelty connect the BBQ on your own. You should do leak testing always and the BBVQ must have approved flame failure device(s).
Which is better for families: Deluxe 2.0 or MAX?
Deluxe 2.0 suits most 2 – 4 person meals and tighter spaces. MAX is better when you want extra cooking depth and more room for group meals (3 – 8 people).
