Our Wall of Flame Rotisseries are packed for safe transport, so that they can reach their
destination without any damages. However, we advise an examination of the Wall of
Flame Rotisserie right after delivery.
Attention! Do report visible damages immediately!
4.1 Unpacking
• Open the box and take out the wrapping and filling material carefully.
• Take out all single parts and check whether these are complete (compare with enclosed dispatch
documents).
• Now please remove the cardboard packaging and all wrapping and covering folios from the rotis-
serie.
4.2 Installation
4.2.1 General information
• Install the feet of the unit and set it up at the place as wanted.
• Set up the unit on an even, horizontal surface! Line up the unit horizontal.
• Observe that all slots for air supply and ventilation are held free and are at least 100
mm away from walls or similar things which could block the slots.
• Take care that the area around the rotisserie is free in order to load, unload, clean the
unit or that maintenance works can be done smoothly.
• The unit has to be set up in a way that the surrounding area can be cleaned.
4.2.2 Place of operation
Attention! The device must be placed on a level, solid and fireproof surface in an well
ventilated room under an on-site extraction hood. Depending on the type, the device
can be placed freely, on a temperature-resistant wall or with other devices in a row. A
minimum distance of 100mm from the sidewalls, the rear wall and walls mad of possibly
combustible material must be met. When these distances are too narrow, you have to
take heat conversation measures, e.g. tiling the walls or affixing of a radiation protection.
Before you connect the device, you have to check the type plate, whether the device is
approved for the used gas type. If the kind of gas indicated on the type plate does not
agree with the required kind of gas, the installation of the device is not allowed until the
unit has been adjusted according to the requirements
4.2.3 Statutory orders, technical regulations and directions
The following regulations have to be observed when the unit is set up:
• local statutory orders
• local laws valid for your countries
• technical regulations for LPG
• directions of the local gas supply company
Furthermore, regulations of accident prevention valid for your country have to be ob-
served.
For operating the unit outside Germany, the national laws, technical regulations and di-
rections of the specific country are valid.

Initial Installation Procedure Page 15
printed: 06/2020 Subject to change! :FFUserManual.docx
4.2.3 Special advices regarding the gas exhaust
Attention! The rotisserie has to be set up in sufficiently ventilated rooms and below an
existing ventilation hood. The unit corresponds to kind of construction "A". The installa-
tion to an exhaust gas device (ventilation hood) is necessary in order to lead out the
exhaust gas immediately.
4.2.4 Installation
Before the installation get the approval from your gas supply company. Only approved
technicians are allowed to make the gas connection in compliance with the following
relevant regulations. The devices require regular maintenance by an approved techni-
cian, especially in regard to burner-, controller-, and safety installations. Maintenance,
conversion to another type of gas should only be carried out by a technician, approved
by the responsible gas supply company.
4.3 Electrical connection
Note! Note that also after installation and electrical connection the plug must be acces-
sible. If this is not possible due to structural reasons, or if the unit is connected perma-
nently, the power supply needs to have an interlock switch.
Note! During any servicing, take care that the unit is disconnected from the mains! Not
paying attention may result in injury!
Please learn the electrical and technical data of your unit from the nameplate.
• The unit is ready for plug-in.
• For power supply a shockproof socket is necessary.
• Make sure the supply cable is protected separately with 16 Amps.
The existing connection cable for the electrical connection is positioned at the lower right
rear wall.
Note!
After finishing any installation work, maintenance or repair check whether the ground
wires are connected properly to the casing.
4.4 Gas connection
Please control, if the device is arranged for the present type of gas. Compare the indi-
cated kind of gas on the type plate with the existing kind of gas. If this is not identical,
you have to make adjustments to meet the local conditions. The gas connection de-
pends on the type (external thread right to DIN-ISO 7/1 [DIN 2999 Part 1] ¾ inch). The
connection with the gas supply has to be made with a connection armature (under ob-
servation of DVGW-TRGI resp. TRF and DVGW- worksheet G-634). Only an approved
technician is allowed to do this. After the gas connection has been made, all connection
points and also the device itself must be checked for leaks. This has to be made under
operating pressure by leak detection spray or by brushing with a non-corrosive foam-
forming medium.
4.4.1 Preparation for operation
The units have to be checked on their designed nominal heat load and adjusted accordingly if re-
quired when they are installed the first time or after any maintenance work. This has to be made.
Please learn the necessary values from the table in section 3.3.7.

Page 16 Initial Installation Procedure
printed: 06/2020 Subject to change! :FFUserManual.docx
4.4.2 Control of nominal heat load
Firstly, please check whether the unit is adjusted for the existing kind of gas. For this you have to
check whether the indication on the type plate corresponds to the existing kind of gas. If you adjust
the unit for other gas types please check the indication of the nozzles. The nominal heat load re-
sults from using the right nozzle with connection pressure of
+ 20 mbar with natural gas H and natural gas L (for France E+)
+ 50 mbar with LPG
by taking effect of the corresponding nozzle area.
The permission of operation with the resulting nominal heat load under dependency of the planned
nozzles results from the following connection pressure bounds:
15 to 25 mbar with natural gases)
25 to 35 mbar and 42.5 to 57.5 mbar with LPG
Starting the operation outside these pressure bounds is not permitted.
The connection pressure is measured by a pressure gauge (indication exactness: 0.1 mbar). For
this the sealing screw in the connection pressure measuring socket of the main gas supply has to
be loosened and the pressure gauge has to be connected.
4.4.3 Checking of nominal heat load with LPG
Check whether the indication of used nozzles corresponds to the indications of the manufacturer.
Secure that the existing low-pressure regulator on site does not exceed a maximum output pres-
sure of 50 mbar according to section 4.4.2 (control of type plate or pressure measurement).
4.4.4 Control of function
• Set the unit into operation according to the manual.
• Check the unit for gas leaks.
• Check the correct adjustment of primary air and nozzles (pilot flame device, main nozzles (at
the burner nozzle assembly), minimum adjustment nozzles (at the all gas valve).
• Check the transmission ignition and regularly flames of the burners with minimum and maximum
adjustment.
• A maintenance contract is recommended.
4.5 Re-adjustment
Attention! Before any re-adjustment works at the unit are executed the main gas supply
has to be closed and the unit has to be unplugged firstly.
All units of our production are single examined and are adjusted for the kind of gas required by the
customer. If no indication has been made, the units are principally adjusted for LPG. If the unit is to
be re-adjusted it has to be observed that this is made by an approved technician or by the Ubert
service technicians. The corresponding nozzles sizes are to be find in the nozzle table. For re-ad-
justment the following measures have to be made:
• Replacement of pilot flame nozzles.

6 Maintenance
Following we give you advices for maintenance, possible trouble shooting and for service cases of
your unit.
6.1 Cleaning and care
6.1.1 Safety advices
• Before you start any cleaning or maintenance work close the main gas supply and
unplug the unit.
• Never use flammable liquids, nor use any sharp or metallic utensils for cleaning your
appliance. Do not use high pressure water or steam appliances! More detailed infor-
mation to follow below.
• Wear acidproof gloves while cleaning the parts to prevent skin irritations.
6.1.2 General Recommendations
• The unit has to be cleaned daily.
• Only use non-poisonous cleaners (neutral or alkaline detergents) which are harm-
less in connection with food, even if there are plain and persistent residues.
• After cleaning with special cleaners, you have to wash all parts with clear water and
dry them afterwards so that there are no residues of the cleaner on these parts.
• It is absolutely necessary to watch out for some fundamental things to keep this
long living high-grade-steel-machine working:
- always keep the high-grade-steel surface clean.
- watch out that there is always enough fresh air on the surface
- never contact the surface with rusty material
• never use bleaching or chlorine cleaners.
• Observe that no residues or waste reaches the burner or thermo element during op-
eration or cleaning, as this can cause damages to the proper control
• of the burner.
6.1.3 Special Recommendations
Control the grease lubrication of the bearings and the chain at least quarterly, more
often if necessary. If the bearings and the chain are not greasy enough, grease them
to ensure a reliable working of the bearing. For lubrication use heat-resistant grease
only. Disregarding follows defect bearings and breakdown of the spit rotation! (Heat-
resistant grease (part no. 412221) and grease guns (part no. 550408) are available at
Ubert.)
6.1.4 Detergents
To make the cleaning fast and easy we have integrated some cleaners in our pro-
gram:
• Stainless steel-cleaner
You have to spray this from a distance of app. 25 cm on the surface and wipe it off
with a dry-cleaning rag. If you want to clean only small parts you have to spray it
directly on the cleaning rag and wipe it off this way. With this method it is possible to
clean the Rotisserie Wall of Flame easily and without stripes.
