4. Installation instructions

4.1. Requirements for oven surroundings

The installer should contact the local building or re ofcials concerning any installation
restrictions or need for inspection of the oven installation.

The minimum hearth extension areas to be covered with relationship to the door opening
of the oven for combustible oors should be the following:

a. 762 mm to each side of the door opening
b. 914 mm in front of the door opening

Clearances to combustible construction/other appliances:

a. Unit to backwall = 76 mm
b. Unit to sidewalls = 76 mm

Countertop models should be placed on a reproof material table or stand, preferably
metals: stainless steel, etc. Such support must be strong enough to support the weight of
the oven.

4.2. Installation and assembly instructions

Due to the high weight of the ovens, it is always necessary to use lifting equipment to handle
them safely. If no such equipment is available, there must be an adequate number of per­sonnel in compliance with local safety regulations, to assist with the installation.

An alternative option to provide more working space inside the heating cabinet is to install
the security accessories outside of the cabinet. In order to do this, connect the extended
ue duct to the oven smoke outlet prenetrating the cabinet’s roof. Assemble the rebreak
and dissipating lter over the duct.

Option 1 Option 2

12

4.3. Smoke extraction

When the oven is installed in the interior of a closed building an extractor hood of sufcient
dimensions is required.

The extractor hood must have a suitable depth in order to cover the opening of the oven
and stand out laterally by 150 mm on both sides.

The ductwork must be either galvanized steel or stainless steel, uniform and well sealed
throughout. It is important to avoid installing horizontal pipes and must provide frequent
access points to remove the build up of solid/liquid residues and creosote, see point 6.3 on
cleaning and special care.

It is recommended that the ductwork is installed with a vent cap in order to improve the
removal of smoke.

MIBRASA® Protective components

Firebreak: Is installed where the smoke
leaves the oven. Its function is to prevent
ames or sparks from escaping the oven.

Dissipating filter: This is installed over the
rebreak. It lters and spreads the ow of
air, slowing it down and dropping its tem­perature.

To guarantee the correct operation of the said components, the recommended
charcoal loads mentioned in point 5.1 should be respected.

13

Installation options

1) Oven with independent extraction

This type of installation consists of an exhaust hood, which is independent of the oven.
The ductwork must be either galvanized or stainless steel, 300/350 mm in diameter up to
the highest part of the building. Installation of the rebreak and the dissipating lter are
needed.

General ventilation ductwork

It is necessary to install the oven with the rebreak and dissipating lter. This will prevent
sparks and ames from escaping the oven. The smoke will be ltered reducing the ow and
cooling its temperature down prior to contact with the ventilation system.

Never connect the oven outlet directly with the
exhaust hood

6. Maintenance and Safety Standards

6.1. Daily cleaning

Do not use chemical products or water to clean the inside of the oven.

Grills: Clean using the grill brush before and after each use.

Ash collector: Open the ash collector, use the ash shovel by Mibrasa® to remove the ash

and transfer to a metal container with a tight-tted lid. If you think it is necessary, you can
remove the ash collector completely from the oven to facilitate cleaning. Once the ashes have
completely cooled down they can be disposed of or used as fertilizer.

WARNING Do not dispose the ashes in a ammable-container or heat-deformable container.

Space between the door and the frame: This should always be kept clean so that it can be
closed properly.

6.2. Weekly cleaning

Dissipating filter: Remove the dissipating lter from the oven. Clean the inside part.

Firebreak:

Remove the rebreak from the oven. Shake gently from side to side to allow the
ash to fall. Never clean with water as the ash will stick to the base and can be difcult to
remove.

Charcoal Grids: Remove the grids and use the grill brush to clean the slits. It is important
for the operation of the oven to keep the slits clear of ash and debris.

Ash collector: Remove the ash collector and clean away any ash and cinders remaining. A
build-up of ash can make closing the ash collector difcult.

6.3. Special care

Exhaust hood and ductwork: It is very important to keep the exhaust hood lters clean as
well as the ducts to avoid a build up of soot and fat, which could result in a possible re.

Follow the weekly cleaning procedures and annual maintenance of the hood, ventilation box
and ue ducts in accordance to the exhaust hood manufacturer’s requirements. Pulverisation
water ltration systems are also accepted to compliment the use of this oven. The ductwork
should be inspected at least twice a year to determine when creosote build up has occured.
When creosote has accumulated, it should be removed to reduce risk of re.

Mibrasa® is not responsible for any damages occurred caused by wrongful use, when the
installation instructions have not been followed or wrongful maintenance of the exhaust hood.

19

Please read this entire manual before you install the oven.

Failure to follow instructions may result in property damage, bodily injury, or even death.

6.4. Safety standards

WARNINGS

• Only use charcoal in the Mibrasa® oven.

• The rst time the oven is used do not cook food for at least one hour after lighting.

• Proceed with reasonable care when operating a Mibrasa® oven. Never leave the oven

unattended when lit.

• Wear heatproof gloves while using the oven.

• The door must remain closed during operation. Open only the door when handling food.

• CAUTION Do not overload/re - when ames spill out of the oven, you are over-ring.

• Disposal of ashes – Ashes should be placed in a metal container with a tight-tting
lid. The closed container of ashes should be placed on a non-combustible oor or on
the ground, well away from all combustible materials, pending nal disposal. When the
ashes are disposed by burial in soil or otherwise locally dispersed, they should be
retained in the closed container until all cinders have thoroughly cooled.

• Do not attempt to pour water over the hot coals, only close the upper and lower dampers.

• Do not clean the oven when it is in operation or hot.

• Do not use chemical products to clean the exterior of the oven when in use or still hot

(the interior of the oven is self-cleaning).

• Do not use products not specied for use with this oven.

DANGERS

• When this oven is not properly installed, a re may result. To reduce the risk of re, follow
the installation instructions.

• Keep children and pets away from the oven and ammable products. Accessible parts of
the oven may be very hot.

• Do not fry food in the oven using oil. The temperature is very high and could cause
serious harm or damage.

• Do not use alcohol, oil or other liquids similar to ignite or rekindle hot coals. Use only
Mibrasa® ecore relighters.

• In the case of installing the oven in an outdoor setting, do not cover the Mibrasa® oven

with any type of protective cover or inammable material when it is in operation or hot.

• Read point 4.1 for restrictions on minimum distances from combustible materials.
