Installation
Minimum acceptable spacing from the terminal to obstructions
and ventilation openings are specified in table 1.
If the lowest part of the terminal is less than 2 metres above the
level of the ground, balcony, flat roof or place to which any
person has access, the terminal must be protected by a guard.
Ensure that the guard is fitted centrally.
The flue assembly shall be so placed or shielded as to prevent
ignition or damage to any part of the building.
The air inlet/products outlet duct and the terminal of the boiler
MUST NOT be closer than 25 mm to combustible material.
Detailed recommendations on the protection of combustible
material are given in BS. 5440- 1:2000.

Air supply and flue gas exhaust in a closed
installation
A ventilation cover is integrated into the 500 Series
condensing gas system boilers. This cover houses a number
of components, such as the burner and the heat exchanger.
Since this ventilation cover is part of the air supply system, it is
vital that it is always installed correctly.

Installation and maintenance instructions for Buderus 500 - 24/S • 08/2006
NOTE
It is absolutely essential to ensure, in practice,
that products of combustion discharging from
the terminal cannot re-enter the building or any
other adjacent building through ventilators,
windows, doors, other sources of natural
air infiltration, or forced ventilation/air-condi-
tioning.
If this could occur the appliance MUST be turned off (with the
owners permission), and labelled as unsafe until corrective
action can be taken.
DANGER!
Only use Buderus flue gas systems.
As other flue gas systems are not tested with
this appliance.
To ensure optimal operation, the 500 Series appliances must
be connected to a Buderus horizontal or vertical flue terminal.
These terminals have been developed specifically for Buderus
condensing gas boilers and have been comprehensively
tested for trouble free operation when correctly installed.
Subject to modifications resulting from technical improvements!
