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
Worktop models: - HMB MINI, MINI PLUS, 75, 110, 160
- HMB SB 75, 110, 160
Lift the oven

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 per-
sonnel in compliance with local safety regulations, to assist with the installation.
1Remove the ash collector
Make sure the forks reach
the end of the oven.

vice in the ash collector space

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.

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.
Dissipating filter: This is installed over the
rebreak. It lters and spreads the ow of
air, slowing it down and dropping its tem-
perature.
To guarantee the correct operation of the said components, the recommended
charcoal loads mentioned in point 5.1 should be respected.
Firebreak: Is installed where the smoke
leaves the oven. Its function is to prevent
ames or sparks from escaping the oven.
MIBRASA®Protective components

14
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.
