Wood Fired Oven Kit – Outdoor Installation
Preparation of the cooking base and cutting the bricks
In this installation, we used a fibre cement board base to install the wood oven on, these are easy, ready to use, fire resistant and affordable.
- Lay the refractory ceramic insulation for the cooking base in position.
Note: By using extra layers of base insulation you will increase the oven efficiency.
The cooking base insulation has been cut to size with a centre line marked.
- Start laying the clay bricks from the front both side of the centre line
- Cut bricks to fit the insulation base.
- Cutting the fire bricks- Score either side with a diamond blade then use a bolster to separate.
Install the oven fascia if applicable
The stainless steel surround is only for aesthetic purposes. You can brick around the oven entrance, mosaic, tile or just render.
- Standard fascia:
1- The return at the bottom fits under the insulation base, the fascia should then be pushed hard against the oven front
2- Tie the fascia back (2 brackets at the back) to the dome with wire threaded through the brackets at the back of fascia.
- Deluxe fascia:
1- It will fit between the marble slab/tiles and the brick cooking base.
2- Tie the fascia back to the dome with wire threaded through the brackets at the back of fascia.
Installing the oven dome
- Stand the oven upright on its entrance 300mm from the front of the concrete base. Lean the oven forward so it is resting against the slab.
Three men will be required, one either side of the oven and the third at the oven entrance.
Lift onto the brick cooking base. Use a car jack to lift and position oven.
- You can also use a metal pole to help positioning the oven.
Preparing the flue
- Cut out the foam chimney plug located at the top of the oven entrance.
- Cut 50mm strips x 4 from flue end and fold them 90 degrees, these will hold the flue in place
- Install chimney flue.
- It is very important to insulate around the flue.
- Insulate the oven with the ceramic fibre blanket provided.
Using extra layers of insulation blanket will increase the efficiency of the oven (faster heating up time and a longer cooking time) and reduces the amount of render.
- Cover insulation blanket with builder ’s sissalation or 2/3 layers of aluminium foil.
- Cover the sissalation / al foil with chicken mesh.
Render the oven dome
- Render approximate 2 to 3 layers over the chicken wire with normal cement and yellow sand.
- Each layer 15- 20mm thick. The more render that is applied the better the insulation.
- Hardware outlets sell bags of Render It, you will need 4 to 5 bags depending on how thick or what shape you decide on.
At this stage you can also mix vermiculite in the render which increases the insulation of the oven.
- If you are mixing your own render use 1 x Brickies Light to 8 x sand on the first coat.
- The second and third coat use a mix of 1 and 6
- If you add Bond crete to the last mix, it will strengthen the final coat.
- You can also add colored oxide to the last coat of render.
- Paint or finish dome as required.
- The render need to be sealed with a render sealer to protect against the weather.
- Please note let the render dry / cure (approx 10 days ) before painting or sealing the oven.
- Wait a week before Pre firing the oven, follow the pre fire steps.
How to cure a wood fired oven for the first time.
Footing size is approximate 200mm x 300mm depending on the size of the blocks or bricks being used.
- Dig out a 100mm deep base with 200mm wide x 300mm deep footings,
- Reinforce with mesh and use PVC plastic under the base.
- Build walls using blocks or bricks.
- Build 100mm slab on top. Reinforce with mesh.
In the example below we show you how to build a wood oven base with blocks and fibre cement board.
- Mix your cement
- Place the cement where you are going to lay the blocks on the footing
- Lay the blocks in place over the cement
- Door jambs can be screwed directly
- Fibre cement board are convenience, light strong and fire resistant.
