2 Product Description
2.1 Product Description
The BOY III is a compact, wall-hanging condensing gas boiler that weighs very little.
The BOY III can be operated dependent or independent of compartment air. All of
the basic parts are inside the powder-coated steel-plated casing. The stainless steel
heat exchanger is designed for exhaust condensation operation and is very self-
cleaning. With its 1:5 modulation ratio, the force draught fan supported burner, de-
signed especially for gas boilers, is very efficient in its energy use and emissions.
The connections can be placed from below the unit. An atmospheric or temperature
sensor can be attached to the boiler controller. These sensors can, depending on
how they are set up, regulate up to two mixing valve circuit.
2.2 Intended use
The BOY III is a condensing gas boiler and is exclusively for use as a heating
unit for heating systems.
Any misuse is prohibited

3.2 Safety Warning
Attention: Electrical installation and initial operation may only be performed by
a licensed professional! This also pertains to maintenance, cleaning, and re-
pair.
●Do not use if system is damaged.
●Only original parts may be used.
●Changes and repairs made on one’s own authority are not allowed, as
such may result in damages to the unit or injury or death.
●When operated in a compartment air-dependent area, ventilation (in
and out) must not be obstructed. The intake of combustion air on the
top of the BOY III must be kept free of obstructions.
3.2.1 What to Do if You Smell Gas
Avoid open fire, smoking, turning on lights, or unplugging anything in rooms
that smell like gas. Under no circumstances should you use the telephone.
Close the gas meter valve! Have your installation technician show you where
the gas valve is and how to close it.
Do not use doorbells or light switches in other rooms.
If you smell gas, use a telephone in a neighbouring building or use a phone
booth. Mobile phones should also be used outside of the building.
Call the service department, even if you smell gas somewhere else.
Do not forget to warn housemates and neighbours and vacate the premises.
Secure the building against unauthorized entry.
Even if you aren’t sure if it is a gas smell, you should contact your energy pro-
vider as a precaution.
3.2.2 Risk of Poisoning
Never use water from the heating system as drinking water! It is contaminated with
deposits.

3.2.3 Risk of Freezing
If the unit is at risk of freezing, it is necessary to be kept operational in conservation
mode (at minimum) and all radiator valves should be kept open. If you cannot heat
during freezing periods, turn off the system and empty the boiler, the warm water
storage tank and the radiators. The boiler must be secured against accidental activa-
tion when empty.
3.2.4 Relief Valve
The condensing gas boiler comes with a 2.5 bar relief
valve. The opening of the spring-loaded membranous
relief valve must be in a frost free area and must be eas-
ily accessible. The blow off pipe on the relief valve must
be implemented without the possibility of increasing
pressure while responding to the relief valve. Leaking
heater water should be safely siphoned off.
Operational readiness of the relief valve should be
checked from time to time. Fig. 4 Relief Valve
3.2.5 Aspirator
To ventilate the boiler with water in it, the
aspirator cap on the top of the unit must be
open by turning it two rotations to the left.
Fig. 5 Manual Quick-Aspirator
An additional automatic aspirator can be
found under the pump casing. This may
only be set by a licensed professional.
