Refractory Stone 475 × 735 × 14 mm for Moretti Forni Pizza Oven

This 475 × 735 × 14 mm refractory stone is designed to replace the deck stone in several compatible professional electric Moretti Forni pizza ovens.

Its large rectangular format forms an important part of the oven’s baking surface.

During heating, the stone stores thermal energy. It then gradually releases this heat to the pizza dough, helping provide consistent baking performance.

Stone dimensions

This refractory stone has the following dimensions:

• Width: 475 mm
• Length / depth: 735 mm
• Thickness: 14 mm
• Shape: rectangular
• Type: refractory deck stone
• Application: professional electric pizza oven

Before ordering, always compare these measurements with the stone currently installed in your oven.

Even a small difference in dimensions can prevent correct installation.

Moretti Forni compatibility

The 475 × 735 × 14 mm format is used in several Moretti Forni oven configurations.

Documented applications include:

• Moretti Forni S100
• Moretti Forni X50 C
• Moretti Forni X100 C
• Moretti Forni X100 K

Professional ovens may exist in different generations and revisions.

Therefore, always check the dimensions of the original stone and the exact configuration of your oven before ordering.

Moretti reference 73900330

Moretti Forni reference 73900330 is documented for a refractory stone measuring 475 × 735 × 14 mm.

This reference is associated in particular with the Moretti X50 / X100 range.

Therefore, if your technical documentation lists reference 73900330, it provides an additional identification criterion.

However, always compare the dimensions, shape and configuration of the original stone before ordering.

Cookmax compatibility

This size is also used in some professional Cookmax pizza ovens.

However, the exact Cookmax model must be checked before ordering.

To confirm compatibility, compare:

• 475 mm width;
• 735 mm depth;
• 14 mm thickness;
• stone shape;
• stone arrangement inside the oven;
• exact appliance model.

Compatibility should therefore not be determined from the brand name alone.

Refractory deck stone

The refractory stone forms part of the oven’s baking deck.

During operation, it absorbs thermal energy and gradually transfers this heat to the pizza.

It helps to:

• maintain an even deck temperature;
• transfer heat efficiently to the dough;
• support even baking of the pizza base;
• retain heat between baking cycles;
• stabilise the baking surface.

For professional electric pizza ovens

This stone is primarily intended for compatible professional electric pizza ovens.

It can replace a stone that is:

• broken;
• severely cracked;
• damaged;
• missing a section;
• unstable;
• heavily worn after repeated baking cycles.

When should a refractory stone be replaced?

Repeated heating and cooling cycles naturally place stress on refractory materials.

Over time, a stone may therefore develop cracks or surface damage.

Replacement is particularly appropriate when:

• the stone is broken into several pieces;
• a significant section is missing;
• the baking surface has become unstable;
• a crack allows sections of the stone to move;
• the stone no longer sits correctly in its support.

A small stable crack does not always require immediate replacement.

Checks before ordering

Before purchasing this stone, always check:

• 475 mm width;
• 735 mm length / depth;
• 14 mm thickness;
• overall stone shape;
• underside configuration;
• arrangement of the stones inside the oven;
• oven manufacturer;
• exact oven model;
• technical reference when available.

These checks significantly reduce the risk of ordering an incompatible stone.

Installing the refractory stone

Before carrying out any work, disconnect the oven from the electrical supply.

Then allow the appliance to cool completely.

Next:

• carefully remove the old stone;
• remove any loose fragments and debris;
• clean the support area;
• inspect the supports;
• position the new stone;
• make sure it sits correctly without mechanical stress.

Never force the stone into position.

Mechanical stress can cause cracking when the oven heats up.

First heat-up

After replacement, increase the oven temperature gradually.

A progressive heat-up helps the stone adapt to its first thermal cycles.

Also avoid sudden temperature changes.

In particular, never pour cold water onto a hot refractory stone.

Stone maintenance

After use, allow the stone to cool naturally.

Then remove dry residues using a suitable brush.

Avoid soaking the stone with water or cleaning products.

Primarily dry cleaning is generally preferable for a refractory deck stone.

Fast shipping

We prepare this refractory stone for fast shipping to help reduce downtime for your professional pizza oven.

Because refractory stones are fragile products, they also require appropriate protective packaging.

Reinforced and highly protective packaging

This stone is prepared with reinforced, highly protective packaging specially adapted to the transport of refractory products.

Particular attention is given to:

• securing the stone inside the package;
• protecting the large surfaces;
• protecting the corners;
• limiting movement during transport;
• reinforcing the outer packaging.

This provides packaging adapted to both the size and fragile nature of the refractory stone.
