How to Set Up and Use an LPG Griddle in a Food Van
Last updated: July 2026
In 30 seconds:
- Fit a propane griddle — never butane, and never a patio-style hookup.
- The connection is a Gas Safe engineer’s job: 37 mbar regulator, commercial hose, isolating valve.
- Allow 20 minutes from cold to full cooking temperature.
- Clean the plate daily and wipe on a light oil coat — a seasoned plate cooks better and lasts longer.
- Lincat GS4/P (5.5 kW, from £1,104) suits smaller vans; GS7/P (8.0 kW, from £1,499) suits busy ones.
Bacon rolls at eight, smash burgers at twelve — no appliance in your van works harder than the griddle. This guide shows you how to set up an LPG griddle properly, light it, run it in zones, and keep the plate in shape for years.
A countertop propane griddle, connected by a Gas Safe registered engineer and supplied at 37 mbar, is the accepted standard hot-plate setup for UK food vans. The Lincat Silverlink 600 griddles are the benchmark most van builders spec first, and every figure in this guide comes from Lincat’s own installation manual.
The biggest mistake we see? Treating a commercial griddle like a big barbecue — hooking it to a patio regulator, skipping the engineer, then wondering why the flame is weak and the warranty is void. Get the connection right once, and the griddle itself is the easy part.
What You’ll Need
- A propane griddle sized for your menu — the Lincat GS4/P or GS7/P for most vans
- A propane cylinder — 13 kg or 19 kg for most setups
- A 37 mbar propane regulator and commercial-grade LPG hose (never a black domestic hose)
- An isolating valve in the supply line
- A level, non-combustible worktop or stand
- A Gas Safe registered engineer to connect and commission it
- Cooking oil and a plate scraper
Step 1: Choose the Right Spot in the Van
Sit the griddle on a level worktop or stand with a metal or open top. Leave at least 750 mm clear above the plate and 50 mm around the sides, with nothing combustible close by.
Why: the burners need a steady flow of fresh air, and hot side panels need breathing room. A cramped corner starves the flame and cooks your wall panels instead of your food.
Step 2: Book a Gas Safe Engineer for the Propane Connection
Have a Gas Safe registered engineer make the connection to the griddle’s 1/2″ BSP inlet. They’ll fit a commercial LPG hose with a safety chain, set the supply to 37 mbar and the burner pressure to 25 mbar, add an isolating valve, and leak-test the whole run.
Why: Lincat’s installation instructions state that work by an unqualified fitter invalidates the warranty. Our LPG hose and regulator rules guide covers the hose standards and replacement dates your engineer will check.
Step 3: Prep the Plate Before Its First Cook
Peel off any protective plastic coating. Wash the plate with warm soapy water, rinse, dry it fully, then wipe on a light coat of cooking oil.
Why: machined steel rusts if it’s left bare. The oil film protects the plate and starts building the seasoned surface that food releases from cleanly.
Step 4: Light the Burners
Press the control knob in fully and turn it anti-clockwise to MAX. Press the orange piezo ignitor, check the flame through the sight hole, and keep the knob held in for 30 seconds before letting go.
Why: those 30 seconds warm the thermocouple — the safety probe that holds the propane valve open. Release too early and the flame failure device shuts the burner straight down.
Step 5: Give It 20 Minutes to Heat Up
Allow around 20 minutes from cold for the plate to reach full working temperature. The thermostat then holds it steady through service.
Why: a thick steel plate heats evenly but slowly. Food dropped on a half-heated plate sticks, stews and greys instead of searing.
Step 6: Cook in Zones
On the GS7/P, run one heat zone hot for searing and the second lower for holding cooked food. In quiet spells, shut one zone down and trade from half the plate.
Why: two separately controlled zones mean you’re not paying to keep 750 mm of steel at searing heat for one bacon roll an hour. Zone discipline is the single biggest propane saver on a griddle.
Step 7: Shut Down and Clean the Plate
Turn the knob clockwise to OFF. While the plate is still warm — not scorching — scrape food residue into the fat drawer, wash with mild detergent and water, rinse, dry, and wipe on a fresh coat of oil.
Why: carbon build-up creates hot spots and off flavours, and an emptied fat drawer won’t overflow into tomorrow’s service. Five minutes at close saves half an hour of scouring later.

How Much Propane Does a Griddle Use?
Less than most traders expect. These are Lincat’s full-rate figures — both burners flat out:
| Model | Propane use (full rate) | 13 kg cylinder lasts |
|---|---|---|
| Lincat GS4/P | 0.39 kg per hour | ~33 hours |
| Lincat GS7/P | 0.57 kg per hour | ~22 hours |
In real service you’ll do better. Once the plate is up to temperature the thermostat cycles the burners, so a typical trading day burns well under the flat-out figure.
Pick a cylinder size with headroom for the rest of your kit — our LPG cylinder sizes guide walks through the maths for a whole van, and the off-grid mobile catering setup guide covers power and water alongside propane.
Staying Safe and Compliant
Flame failure device. Both Silverlink 600 griddles have one fitted. If the flame goes out — a gust through the hatch, a knocked knob — it cuts the propane automatically instead of letting it pool in the van.
Ventilation. Burners consume air as they work, so the van needs fixed low-level ventilation and a good flow of fresh air. Your engineer should confirm the van’s ventilation suits the total heat input of everything fitted.
Servicing. Lincat recommends a service by a competent engineer every six months. Most traders pair one visit with the annual gas safety certificate that councils and event organisers typically expect — the CP44 certificate, the commercial catering version of a landlord’s certificate — covering the van’s whole propane system.
Common Mistakes to Avoid
- Using a patio regulator or domestic hose. Wrong pressure, wrong hose rating, void warranty. Commercial kit only.
- Cooking before the 20-minute heat-up. Food sticks and stews on a half-heated plate.
- Releasing the knob straight after ignition. The thermocouple needs 30 seconds, or the burner drops out.
- Sluicing a hot plate with cold water. Let it cool to warm first — thermal shock is how plates warp.
- Skipping the oil coat. A bare steel plate rusts overnight in a damp van.
- Running both zones all day. Shut one down in quiet spells — it’s the easiest propane saving you’ll make.
Frequently Asked Questions
Can I install an LPG griddle in a food van myself?
No — the propane connection should be made and commissioned by a Gas Safe registered engineer. Lincat’s installation instructions state that work by an unqualified fitter invalidates the warranty. The engineer sets the regulator, fits commercial-grade hose with a safety chain, adds an isolating valve and leak-tests the run. Budget roughly £120–£180 for the visit.
What pressure does a propane griddle run at?
UK commercial mobile catering runs on propane at a 37 mbar supply pressure. On the Lincat GS4/P and GS7/P the engineer then sets the burner pressure to 25 mbar at the test nipple. Both figures come from Lincat’s installation manual — they’re checked at commissioning and again at every service.
How long does an LPG griddle take to heat up?
Around 20 minutes from cold to full working temperature. The thermostat then holds the plate steady, so you can turn it down between rushes without losing the plate. Lighting is quick: hold the knob in for 30 seconds after ignition so the thermocouple warms up and keeps the propane valve open.
Can I run a food-van griddle on butane?
No — use propane. Butane stops vaporising below about 2°C, so a butane cylinder can leave you with no heat on a cold UK morning. Commercial catering appliances, including the Lincat Silverlink 600 griddles, are rated for propane at 37 mbar. Butane belongs on patio heaters and camping stoves, not in a working food van.
How much propane does a griddle use per day?
At full rate the GS4/P burns 0.39 kg of propane an hour and the GS7/P burns 0.57 kg. A 13 kg cylinder gives roughly 33 or 22 hours flat out. In real service you’ll get more, because the thermostat cycles the burners once the plate is up to temperature.
Do I need to season a steel griddle plate?
Yes. Wash the new plate with warm soapy water, dry it fully, then wipe on a light coat of cooking oil before first use. Repeat the oil coat after every clean-down. The film stops the machined steel rusting overnight and builds the slick, even surface that eggs and burgers release from cleanly.
What’s the difference between the Lincat GS4/P and GS7/P?
Size and power. The GS4/P is 450 mm wide, 5.5 kW and 33 kg — right for smaller vans and lighter menus, from £1,104. The GS7/P is 750 mm wide, 8.0 kW and 54 kg, with two separately controlled heat zones and output of up to 190 quarter-pound burgers an hour, from £1,499.
How often should an LPG griddle be serviced?
Lincat recommends a service by a competent engineer every six months. Most traders pair one of those visits with the annual gas safety certificate that councils and event organisers typically expect for the van’s whole propane system. Regular servicing keeps burner pressure correct and catches worn thermocouples before they fail mid-shift.
