Gasmax Gas Outdoor Hokker Stove GHS-400

The Gasmax GHS-400 is a portable outdoor wok (hokker) stove on medium-pressure LPG/propane, with cast iron burners and a 418 x 418 mm stainless steel cooking grate. Designed for commercial OUTDOOR use only, and installation and connection must be carried out by a licensed gasfitter.

Why operators choose the GHS-400

• Commercial OUTDOOR use only — the source is explicit and it is the first thing to know. This is not an indoor appliance and must not be brought inside or under an enclosed canopy. Used outdoors as intended it suits night markets, festivals and event catering
• Connection by a licensed gasfitter — a medium-pressure LPG appliance is not a plug-in. Your gasfitter sizes the regulator and hose and certifies the installation
• Medium-pressure gas system on LPG/propane — medium pressure is what produces the flame a wok actually needs. A low-pressure burner cannot deliver the same heat into the base of a wok, which is why a dedicated wok stove exists at all
• Heavy-duty cast iron burners — cast iron takes direct flame and thermal shock year after year, which is why it is still used on wok burners
• 418 x 418 mm stainless steel cooking grate, sized for wok work
• Portable, 18 kg, with non-slip feet for uneven ground — the feet are the detail that matters on grass or gravel at an event
• We are NOT publishing a gas output figure — our two records disagree by roughly a factor of twenty and we would rather tell you that than print a number. See Installation and delivery
• Warranty terms vary — our two warranty records disagree on whether labour is covered, so we are not going to state a term. Ask us and we will confirm before you buy

Specifications

Venue suitability

An outdoor wok stove suits night markets, food trucks, festival and event catering and any outdoor service needing serious heat under a wok. Because it is specified for outdoor use only, it is an addition to a kitchen rather than part of one.

Installation & delivery

This is a gas appliance: installation and connection must be carried out by a licensed gasfitter. It runs on a medium-pressure LPG/propane system, so the regulator and hose are part of that job rather than accessories you buy separately. It is specified for commercial OUTDOOR use only — do not bring it indoors or under an enclosed canopy. On the gas output: we are not publishing one. Our specification field records "58MJ / 6h" while the description claims "200,000+ BTU". Converted, those are roughly 10 and 211 megajoules per hour — about twenty times apart. Both cannot be right and we have no basis to choose, so rather than print a figure your gasfitter might size a supply from, we have left it out and flagged both records. Ask us and we will get the output confirmed. Dimensions are recorded width x depth x height: 418 x 474 x 446 mm at 18 kg — genuinely portable, and it packs to 550 x 500 x 520 mm.

Warranty terms are per product — see our warranty information page.

Frequently asked questions

Q: Can I use it indoors?

No. The source specifies commercial outdoor use only, and that is not a formality - an outdoor gas appliance is not designed for the ventilation and clearances an indoor kitchen requires. It must not be brought inside or run under an enclosed canopy. If you need a wok burner for an indoor kitchen, contact us and we will point you at one built for it.

Q: What gas output does it produce?

We are not going to give you a number, and here is why. Our specification field records "58MJ / 6h" and the description claims "200,000+ BTU" - converted, that is roughly 10 megajoules an hour against roughly 211. They are about twenty times apart, both cannot be correct, and we have no basis to pick one. Since a gasfitter would size the supply from that figure, printing the wrong one would be worse than printing none. Ask us and we will have the output confirmed with the supplier.

Q: Do I need a gasfitter?

Yes. It runs on a medium-pressure LPG/propane system and the connection must be made and certified by a licensed gasfitter, who will also size the regulator and hose. That applies outdoors just as it does indoors.

Q: Why medium pressure rather than a standard burner?

Because wok cooking needs a flame that a low-pressure burner cannot produce. Medium pressure is what delivers the intense, concentrated heat that gives stir-fried food its character - it is the reason to buy a dedicated wok stove rather than cooking on a general-purpose burner.

Q: What warranty does it carry?

Our two records disagree, so we are not going to state a term. One says two years parts and labour plus two years parts-only with registration; the other says two years parts only. Whether labour is covered is a material promise and we would rather confirm it than guess - ask us before you buy, and see our warranty information page.
