G'day Gary,

This is a common question! 23 Zero refers to this extra flat plate as an Ash Collector Plate. It is designed to go on top of the grate to keep your coals from falling through if you want to cook something like baked potatoes with your firepit. 

G'day Ben,

There isn't a particular flat plate made for this firepit but you could use a BBQ Hotplate or similar on top of the grill. 

G'day John,

Yes! Everything in the box including the grill weighs a total of 8kgs. 

G'day Mic,

I have just confirmed some measurements with 23 Zero and the Firepit without the grill is 42cm x 42cm and 18cm deep.

G'day Matt,

At the moment there is no base plate available for this Firepit.

G'day Pedr,

They're all very similar fire pits.  We don't sell Kings so I cant comment on that one, although it sounds more like an issue with the fuel source/tinders they're using as opposed to the fire pit itself.
Realistically with the styles of collapsible fire pits there isn't going to be a huge amount of difference in how they burn.  The 23Zero firepit has an open base, which may draw air more efficiently and contribute to a better burn, but we don't really have any customer feedback suggesting one is necessarily better than the other.
Hope that helps.

G'day Rick,

As you can see by the third picture, the grill takes up the entire top of the firepit, covering its most external points.
The Fire Pit dimensions are listed in the specifications - 47.5cm2 - and with the very narrow strip of stainless steel on two edge of the grill plate, the active grill section is around 47.5 x 45 cm.

Hope that helps.

G'day Gordon,

23Zero is primarily manufactured in China.
Hope that helps!
