General Information
1.7 - THE FOLLOWING INSTRUCTION MUST
BE FOLLOWED
-
The boiler must only be used for its designated purpose,
as described in the Installation Instructions.
-
Each unit is fitted with a data plate. Consult the details on
this plate to verify whether the boiler is compliant with its
intended location, e.g.: gas type, power source and ven-
ting classification.
-
Only use the boiler with the accessories and spare parts
listed.
-
Other combinations, accessories and consumables must
only be used if they are specifically designed for the inten-
ded application and do not affect the system performance
and the safety requirements.
-
Maintenance and repairs must only performed by trained
professionals.
-
Installation of a condensing gas boiler must be reported to
the relevant gas utility company and have it approved.
-
You are only allowed to operate the condensing gas boiler
with the vent system that has been specifically designed
and approved for this type of boiler.
-
Please note that local permission for the vent system and
the condensate water connection to the public sewer sy-
stem may be required.
You must also respect:
-
The local building codes stipulating the installation rules.
-
The local building codes concerning the air intake and
outlet systems and the chimney connection.
-
The regulations for the power supply connection.
-
The technical rules laid down by the gas utility company
concerning the connection of the gas connection to the
local gas mains.
-
The instructions and standards concerning the safety equi-
pment for the water/space heating system.
-
The Installation Instructions for building heating systems.
-
The boiler must be located in an area where leakage of
the boiler or connections will not result in damage to the
area adjacent to the boiler or to lower floors of the structu-
re. When such locations cannot be avoided, it is recom-
mended that a suitable drain pan be installed under the
boiler.
-
The boiler must be installed in such way that the all com-
ponents are protected from water (dripping, spraying, rain
etc.) during boiler operation and service.
-
The boiler must not be installed on or against carpeting.
-
Do not restrict or seal any air intake or outlet openings.
-
If you find any defects, you must inform the owner of the
system of the defect and the associated hazard in writing.
DANGER.
Gas is flammable and may cause an explo-
sion.
Beware if you smell gas: there may be an explo-
sion hazard!
If the information in these instructions is not followed exactly,
a fire or explosion may result causing property damage,
personal injury or death.
-
Do not store or use gasoline or other flammable vapors
and liquids in the vicinity of this or any other appliance.

WARNING
WHAT TO DO IF YOU SMELL GAS
- Do NOT try to light any appliance.
- Do NOT touch any electrical switch.
- Do NOT use any phone in your building.
- Immediately call your gas supplier from a
neighbor's phone. Follow the gas supplier's in-
structions.
- If you cannot reach your gas supllier, call the
fire department.
WARNING
Should overheating occur or the gas supply
fail to shut off, do not turn off or disconnect
the electrical supply to the pump. Instead,
shut off the gas supply at a location external
to the boiler.
Unsuitable heating system water can cause the formation of
scale or sludge, which affects system efficiency. It can also
cause corrosion and reduce life of the heat
exchanger.
-
You must follow guidelines for boiler water
quality.
-
Thoroughly flush the system prior to filling.
-
Follow the LATTNER cleaning instructions.
-
Never use water that has been treated by a reverse
osmosis, D.I., or distilled water to soften the water to fill
the heating system.
-
Do not use inhibitors or other additives unless appro-
ved by LATTNER for that purpose!
-
When frost protection of the heating system is desired,
only use LATTNER-approved antifreezes. The allowed
maximum concentration is 50%.
-
When using oxygen-permeable pipes, e. g. for under
floor heating systems, you must separate the system
from the boiler using plate heat exchangers.
-
Valve off boiler while flushing system, do not introduce
any system cleaner into the boiler loop. Flush system
thoroughly to remove all system cleaner before filling
boiler.
Approved antifreeze (max. concentration 50%):
•
Rhomar RhoGard Mutli-Metal (AL safe)
•
Noble Noburst AL
Approved system cleaner:
•
Noble Noburst Hydronic System Cleaner
•
Fernox F3 Cleaner
•
Rhomar Hydro-Solv 9100
The system cleaners from NoBurst, Rhomar, and
Fernox are not to be used in the boiler. The boiler
must be closed off (valved off) from the rest of the
system or not connected while the cleaners are
in the system. The system should then be drai-
ned and then thoroughly flushed with clean wa-
ter to remove all the system cleaner.
Approved inhibitors:
• Rhomar Pro-tek 922
• Noble Noburst AL inhibitor
