The Zesti oven is made from high quality stainless steel components. Maintenance of your oven is quite simple and involves nothing more than regular cleaning with a good stainless steel spray or cleaner that is available from most supermarkets and hardware stores. Depending on your location, frequency of cleaning will vary. If you are close to the coast where salt water can affect your unit you would probably want to wipe your oven over at least every 2 weeks, even if your oven has not been used. 

If maintenance is ignored you will most likely develop some tea-staining on your arch, flue and stainless steel tube around the base. Please note that tea-staining is not rust. It is particles in the air that land on your oven and oxidise turning into a yellow/gold colour. This will happen to any stainless if it is not frequently cleaned, even on marine grade 316.

If tea-staining does occur it is not permanent, but will require a bit more effort in cleaning and restoring the oven back to its original condition. 

A good quality scotch bright pad can be used with a little water (and elbow grease).

Cupping the scotch-bright pad in your hand rub the stainless steel over making sure you follow the grain in the metal. If the stains are stubborn you may need to use some water on the pad also. Work on one area at a time rubbing the pad back and forth over that area. You should notice the tea-staining start to clear. The more time you put into this process the better the result. Hint: By cupping your hand and scotch-bright around the curve of the arch will help in following the grained pattern of the arch. 

Once you are satisfied with the result, dry the oven with a soft cloth and spray and wipe with a good stainless steel cleaner.

This process will take time and patience, but as mentioned above, regular cleaning will prevent this for occurring in the first place so keep this up.

Installing A Pizza Oven

We service most metro areas.

Modular Kit Ovens

We have qualified experienced pizza oven builders that can assist with building DIY modular kit pizza ovens. Please contact us.

Ready Built Ovens

We can recommend experienced installers that can lift and move heavy ready built ovens from your driveway into your garden backyard area. Including lifting and moving equipment, trollies, hoists etc.

Modular DIY Kit Ovens

Our modular pre-cast Kit ovens are easy to install. No bricklaying or brick cutting required. The pre-cast refractory concrete pieces need to be assembled on a support masonry base and the concrete render applied to the external dome. You can find a local builder, concreter or brickayer to install the oven. Try https://hipages.com.au/ or Gumtree, Air Tasker

Ready Built Ovens

You can hire lifting and moving equipment from Kennards HIre to lift and move the ready built oven from your driveway into your garden backyard area. Trollies and hoists etc.

Try your local removalists, Gumtree or Air Tasker for labour hire and equipment services (eg. ute with hydraulic crane or Hi-ab crane).

There are a few things to consider when getting a pizza oven.

Does your property have flat, wide, and easy access?
If your property has stairs, narrow pathways, a steep driveway, or gates, be sure to check the size and weight of the oven to ensure that the oven will be appropriate for your property.

To install your new pizza oven, we recommend using a dolly trolley to move the oven to your desired location and using an engine hoist to be able to safely lift your oven.

Outside oven dome or hood:

It will depend on the oven model. The concrete rendered heavy duty ovens are normally warm to touch on the outside dome.

Other ovens and stainless steel ovens may reach temperatures approx 50-70c on the outer sides. The base of the stainless steel ovens can reach temperatures of 80c.

Heat Transfer to bench:

The temperature under the cooking floor of the oven will vary, depending on the size of the fire and the oven however, approx. 80C degrees is common.

Our ovens has been designed for outdoor use. However ovens require “all-weather” protection from rain and the harsh elements when not in use.  We supply high quality, weatherproof, UV resistant, custom-made covers.  Please contact us if you would like to order one.

It is reccomended to be placed away from any flammable material. It is important that there are no obstructions and that there is free space around the oven of at least 20 centimetres.

You can install or build your wood fired oven outdoors or in an alfresco outdoor area under a roof.

We find that many local councils do not have an issue and generally do not have any specific rules in regards to having a pizza oven at home. However to avoid any issues, please feel free to contact local council to confirm this is the case for your area.

The ZRW Wood fired Oven is a fully finished one-piece Unit which is fully insulated to 1260.C. This means that the Oven can be placed upon any non-combustible Top as long as the top is not supported or braced by frame work which is combustible such as timber.

We would advise a metal frame work to hold for instance, a stone top as products are insulated for an hourly rate. The Woodfired Ovens will hold their heat for 6 Hours + , thus eventually heat can transfer through the base to the materials below.

The ZRW Woodfired Oven is fully insulated externally thus it will not combust products that surround the Unit from the rear or the sides.

The only part of the Oven which is not insulated and conducts temperatures that can combust materials if they are placed near by is the stainless steel front arch and Flue assembly.

Install your oven on a flat, level surface. Ideally Hebel or concrete bench top is preferred on a Brick or Besser Block or a steel metal stand.

Ensure that the support base or bench structure can hold the weight of the oven and the bench dimensions suit the oven size. (please refer to product description).

For most family size pizza ovens a support base bench 1200Wx 1200D x 1000H will suit. For our XL ovens please check our product FAQs document.

Using the dimension specifications found in our product descriptions, draw a full scale outline of the particualr oven on a large piece of paper or cardboard. This way you can see if the oven will fit in the desired location.

Base Bench Construction:

Masonry & Concrete Base Bench:

Block walls in a U shape (open at the front for wood storage)

Besser 200mm block walls core filled (with a 100mm thick reinforced concrete slab top or Hebel Power Panels for the top)

Hebel Base Bench:

CSR Hebel 200mm block walls (with CSR Hebel power panels
on top of the block walls).

Contact CSR Hebel to find your local supplier:


See our base design drawings (with measurements) under our product FAQS document for each oven model.

Metal Stand: we offer several pizza ovens with a metal stand option. Some ovens may need a stand custom made to order (by a metal fabricator). For heavy duty Pre Cast Modular Kit ovens we recommend laying CSR Hebel reinforced power panels into the angle frame top of the metal stand.

You may consider bench top materials that are non combustible and heat resistant
for example tiles, natural granite stone or Dekton (type of porcelain).

We recommend you speak to your benchtop installer so they are aware of your intended oven installation.

We cannot recommend mounting ovens onto engineered (man made) stone benches. However, some clients successfully mount light-weight smaller ovens (with bench mount
short legs) on to this type of engineered stone bench tops with no issues. These
ovens with bench mount short legs allow air flow and help raise the oven cooking
floor off the bench surface. You can also lay a sheet of non combustible 6mm cement
board sheeting under the oven for added insulation and protection.

Cement board sheeting: for example Villaboard James Hardie
from Bunnings.


Do I need to extend the flue through the roof?

You may not need to extend/divert the flue or install a flue roof kit If the pizza oven is located in a well ventilated outdoor area with open sides and a high roof. There may be no issues if the outdoor area under the roof is well ventilated. We suggest that you initially install the pizza oven and use the oven a couple of times to determine the smoke output. If smoke is an issue you can use 45o degree bends and extensions to divert the flue out of the area past the roof or nstall a flue system through the roof.

We recommend that you can contact your local fireplace shop or flue chimney supplier for Flues and Triple Skin Insulated Flue Roof Kits. We highly recommend that the flue is installed by an experienced, qualified flue chimney installer (licensed plumber or builder) to meet Aus. Standard AS291.

You may need a double or “Triple Skin Insulated 4 x metre Flue Kit” to meet Aus Standard AS2918 if the flue is going through an insulated roof or within 25mm of combustible materials (e.g., plaster, timber frames etc).

If your flue chimney is not going through a roof, you may only require “Single Skin” extra lengths of flue pipe (and bends) to extend or divert the flue.

If you need further assistance and advice feel free to email us info@pizzaovensrus.com.au
with the oven model, photos/details and dimensions of the proposed installation
location, the ceiling height measurements and external roof photos (tiles, colorbond etc). 


The stainless steel flue pipes can be spray painted black easily with Stove Bright Black Fireplace Heatproof spray paint.
