GENERAL INFORMATION
Observe these instructions as general warnings:
− recommends that an inhibitor - suitable for use with
R
stainless steel heat exchangers - is used to protect the boil-
er and system from the effects of corrosion and/or elec-
trolytic action. The inhibitor must be administered in strict
accordance with the manufacturers instructions.
− When the boiler has been filled for the first time or the sys-
tem has been drained and refilled, it will be necessary to
purge any air that may have become trapped within the
appliance heat exchanger.
NOTE: Propylene glycol in the system must not exceed 40%.
Boiler water
− If you have an old system with cast iron radiators, thor-
oughly flush the system (without the boiler connected) to
remove sediment. The high-efficiency heat exchanger can
be damaged by build-up or corrosion due to sediment
− Do not use petroleum-based cleaning or sealing com-
pounds in the boiler system. Gaskets and seals in the sys-
tem may be damaged. This can result in substantial prop-
erty damage.
− Do not use "homemade cures" or "boiler patent medi-
cines." Substantial property damage, damage to boiler,
and/ or serious personal injury may result.
− Continual fresh make-up water will reduce boiler life. Min-
eral build up in heat exchanger reduces heat transfer, over-
heats the stainless steel heat exchanger, and causes failure.
Addition of oxygen carried in by make-up water can cause
internal corrosion in system components. Leaks in the boil-
er or piping must be repaired at once to prevent make-up
water.
− We recommend the use of water treatment additives to
prolong the life of the boiler and prevent against corrosion
and contaminant build ups in the heating system.
− Ensure piping in the heating system has an oxygen barrier.
Observe these instructions for space heating water:
− Thoroughly flush the system prior to filling. Only use un-
treated potable water to fill and top off the system.
− Do not use water softeners in the system.
− When using oxygen-permeable pipes, e.g. for floor heat-
ing systems, you must separate the system using heat ex-
changers. Unsuitable heating system water promotes the
formation of sludge and corrosion. This may damage the
heat exchanger or affect its operation.
Tools, materials and additional equipment
For the installation and maintenance of the boiler you will need
the standard tools for space heating, gas and water connection.
Disposal:
− Dispose of the boiler packaging in an environmentally
sound manner.
− Dispose of components of the heating system (e. g. boiler or
control device), that must be replaced, by taking them in to
an authorized recycling facility.

WARNING: If the information in these instructions is not fol-
lowed exactly, a fire or explosion may result causing property
damage, personal injury or death.
9
WARNING: Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other boiler.
0
WARNING: Do not obstruct or restrict the vents in the room
where the boiler is installed. Adequate ventilation is essential
for correct combustion. Failure to comply may result in sub-
stantial property damage, severe personal injury or death.
0
WARNING: Do not expose the appliance to weather elements.
It has been designed for indoor use only.
0
CAUTION: Do not switch off the appliance if the outdoor tem-
perature may drop below 32°F (0°C) (freezing hazard).
0
CAUTION: Do not activate the boiler without adequate water in
the heating system.
0
Individuals without specific qualifications and skills shall not
remove the boiler's casing.
0
Individuals without specific qualifications and skills shall not
remove the boiler's casing.

NOTE:
− Do not install a thermostatic flue gas damper downstream
of the draft hood.
− Do not tamper with, remove, or attempt to repair a blocked
vent switch.
− When replacing the blocked vent switch, install the new
part in the original location.
− A blocked vent switch tripping more than once indicates a
problem with the venting system or chimney which must
be repaired immediately.
− Ensure none of the vent pipes and chimneys are damaged
or blocked.
− Connect only one appliance to each venting system or
chimney, unless using an approved cascade vent system
listed in the section "Installation of the exhaust and air in-
take system".
− The venting system must not feed into or route through an-
other exhaust flue.
− The venting system must be inspected annually. All parts
that show any signs of damage or corrosion must be re-
placed.
− Never close off or reduce the size of the combustion air
openings.
− The boiler must not be operated until any obstructions have
been removed.
9
NOTE:
− Work on gas components may only be carried out by a
qualified installer, service agency or gas supplier.
− Appliance installation, the connection of gas and vent pip-
ing, initial commissioning, electrical connections and ser-
vice and maintenance must only be carried out qualified
installer, service agency or gas supplier.
