Frequently Asked Questions - Big Bakers Oven Nectre

How do I start a fire in the Nectre Big Bakers Oven?

Place small kindling and firelighters on the firebrick floor, light them, and gradually add larger wood logs. Ensure the flue is open. Never use accelerants.

What type of wood should I use?

Use seasoned hardwood like oak, maple, or birch. Avoid softwoods like pine which produce excess creosote. Moisture content should be below 20%.

How long does it take to heat up?

Approximately 30-45 minutes to reach pizza-cooking temperature (around 400°C). Preheat with a medium fire.

Can I bake bread in this oven?

Yes, the Big Bakers Oven is excellent for bread. After the pizza fire dies down, the retained heat is perfect for baking. Use a baking stone if desired.

How do I clean the oven?

Remove ash after each use with a shovel and brush. Wipe the exterior with a damp cloth. Never use water on the interior while hot.

Is it safe to use in a covered patio?

Yes, but ensure adequate ventilation. The area should be open on at least two sides. Never use indoors.

What maintenance is required?

Regularly check door seals for wear, clean the flue annually, and inspect firebricks for cracks. Replace damaged bricks promptly.

Can I use charcoal instead of wood?

Charcoal can be used but will burn hotter and faster. Mix with wood for best results. Do not use charcoal briquettes with additives.

How do I control the temperature?

Adjust the airflow by partially closing the door or flue damper. More air increases temperature, less air decreases. Monitor with a thermometer.

Where can I find replacement parts?

Replacement firebricks, door seals, and grates are available through Nectre dealers or online. Use only genuine parts.

1. INSTALLATION

THE INSTALLATION INSTRUCTIONS IN THIS MANUAL APPLY TO THE NECTRE BIG BAKERS OVEN.

1.1. IMPORTANT INFORMATION

The unit must be installed according to all manufacturers' instructions included in this manual. The manufacturer is not liable for installations that do not meet the requirements outlined in this manual.

Most building regulatory authorities in Australia require any wood heater installation to comply with Installation Standard AS/NZS 2918. Different states and councils may have varying regulations. Check local building regulations before installing the appliance.

All Nectre wood heaters have been tested to ensure they will meet the appropriate safety standard requirements if the instructions in this manual are followed. As the safety and emissions performance can be affected by altering the appliance, no modifications are allowed without written permission from the manufacturer.

WE RECOMMEND THAT THE INSTALLATION OF YOUR NECTRE WOOD HEATER BE CARRIED OUT BY A QUALIFIED INSTALLER.

WARNING: THE APPLIANCE AND FLUE SYSTEM SHALL BE INSTALLED IN ACCORDANCE WITH AS/NZS 2918 AND THE APPROPRIATE REQUIREMENTS OF THE RELEVANT BUILDING CODE OR CODES.

ANY MODIFICATION OF THE APPLIANCE THAT HAS NOT BEEN APPROVED IN WRITING BY THE TESTING AUTHORITY IS CONSIDERED TO BE IN BREACH OF THE APPROVAL GRANTED FOR COMPLIANCE WITH AS/NZS 4012 & AS/NZS 4013.

CAUTION: MIXING OF APPLIANCE OR FLUE-SYSTEM COMPONENTS FROM DIFFERENT SOURCES OR MODIFYING THE DIMENSIONAL SPECIFICATION OF COMPONENTS MAY RESULT IN HAZARDOUS CONDITIONS. WHERE SUCH ACTION IS CONSIDERED, THE MANUFACTURER SHOULD BE CONSULTED IN THE FIRST INSTANCE.

CAUTION: CRACKED AND BROKEN COMPONENTS, EG. GLASS PANELS OR CERAMIC TILES, MAY RENDER THE INSTALLATION UNSAFE.

1.2. INSTALLING THE HEATER

1.2.1. Positioning the Heater

Review the necessary clearances specified in this section before considering where to position the heater.

Also check the practicability of installing the flue system in relation to any obstructing roof beams before positioning the heater.

The clearance distances can only be reduced if the surrounding walls are made of non-combustible material such as stone, brick or concrete. If non-combustible material, distance can be reduced to 100 mm. Alternatively, shielding of the wall(s) can reduce clearances (refer to next section for more detail).

1.2.2. Standard Installation

Dimensions given in the image below represent the minimum clearance (in millimetres) to combustible materials.

Side clearance = 325mm

Rear clearance = 125mm

1.2.3. Corner Installation

Dimensions given in the image below represent the minimum clearance (in millimetres) to combustible materials.

Corner clearance = 275mm

1.2.4. Floor Protector

Unless the heater will be standing on a heat resistant floor such as concrete slab with slate or tiles, it will be necessary to provide a floor protector.

The minimum required dimensions for the floor protector are shown in the previous images. It must extend no less than 300mm in front of the door opening, no less than 200mm either side of the door opening and extend under the heater. Minimum dimensions for the floor protector are 900mm wide by 900mm deep. It may be desirable, for example aesthetic reasons, for the floor protector to be larger than these minimum dimensions.

The floor protector shall be constructed of non-combustible material no less than 15mm thick and with a thermal conductivity not greater than 0.33W/m °K, eg. compressed cement sheet.

The floor protector may be laid directly on the combustible floor.

For more details and variations on floor protectors refer to AS/NZS 2918 Clause 2.2, 3.3.1, & 3.3.2.

1.3. REDUCING CLEARANCES TO COMBUSTIBLES

If it is necessary to install a heater closer to a combustible surface than the stated requirements in this installation manual, it must be done in accordance with Australian Standard AS/NZS 2918:2018 Section 3, Tables 3.1 & 3.2.

Shield Construction: The shield shall be constructed from a heat resistant material. The shield must be fixed to the surface that requires protection and NOT the heater.

The Standard allows three options to reduce stated clearances.

Single layer of continuous material with Minimum Air Gap of 12mm—Clearance Factor = 0.40

Single layer of continuous material with Minimum Air Gap of 25mm—Clearance Factor = 0.30

Two spaced layers of continuous material with Minimum Air Gaps of 12mm + 12mm—Clearance Factor = 0.20

The shielding must be open at the top and bottom (vented) to allow a continuous air flow. It is this air flow that keeps the surface requiring protection cool. Fixings should not impede this air flow.

The shielding needs to go far enough along and up the wall so that the original side and rear required clearances are not compromised. As the flue is now closer to the wall the shielding should also protect the wall from the flue pipe.

Example:

The side wall clearance for a heater is 325mm.

A 12mm gapped shield on the wall with a factor of 0.40.

Calculate: 325mm x 0.40 = 130mm. This is the new side wall minimum clearance.

The shielding needs to be large enough so that none of the original clearances of 325mm are compromised.

1.4. INSTALLING THE BYPASS DAMPER HANDLE

Before installing the flue, the bypass damper handle must be fitted. The handle is supplied inside the firebox.

1) Insert the threaded end of the handle into the 10mm hole on left side of heater.
2) Looking down through the flue spigot, locate the threaded end of the handle with the connector attached to the by-pass damper.
3) Screw the handle all the way into the nut until tight.

The position of the handle should be at approximately 11 o'clock when the damper is open, and 1 o'clock when the damper is shut.

1.5. INSTALLING THE FLUE

Before installing flue, the bypass damper handle must be fitted (see section 'Installing the Bypass Damper Handle').

The flue system used when installing the heater MUST comply with the current installation standard AS/NZS 2918.

Full instructions on the installation of the flue will be supplied with the flue kit. These MUST be adhered to, including the minimum exit height from the top of the floor protector being not less than 4.6m, and the minimum exit height above the roof line of roof ridge as detailed in the instructions.

The flue must be fitted with a 900mm long, minimum 150° arc, stainless steel unpainted rear flue shield.

If the draft is insufficient or periodic down drafting occurs and the heater smokes or only burns slowly, extending the flue or fitting a specialist cowl will usually resolve the issue.

1.6. INSTALLING FIRE BRICKS

The Nectre Big Bakers Oven comes with 4 bricks (230 x 115 x 38mm) held by a 495mm long brick retainer and 2 triangular bricks (50 x 70 x 250mm) for the front.

1) Place the four fire bricks upright, up against the rear wall of the firebox.
2) Place the brick retainer over the top of the bricks to hold them in place.
3) Place the triangular firebricks at the front of the firebox beneath the door opening.

The firebricks may already be in place upon arrival of the new appliance.

The Nectre Big Bakers Oven is supplied with two 8mm thick sacrificial shields fitted to the sides of the firebox to protect the walls of the firebox.

Lugs on the shields allow them to hang over the angled cut-out on the sides of the firebox along the top.

The firebox side shields may already be in place upon arrival of the new appliance.

1.8. INSTALLING BAFFLE PLATE

The Nectre Big Bakers Oven is supplied with a 248 x 463 x 6mm baffle plate. This rests on the two lugs welded to the inside front of the firebox and on the brick retainer at the back of the heater.

Ensure the baffle plate is pushed all the way to the back so it does not fall during operation.

1.9. INSTALLING TOP AIR CONTROL HANDLE

A stainless steel rod with a thread at one end and black knob on the other will have been supplied in the heater.

1) Pass the threaded end of the rod through the hole near the top front corner on the left side of the heater.
2) Push the rod through until it has located the nut on the air slide
3) Screw rod until tight.
4) Check that the rod slides freely back and forth.
