4.16 Drainage
In every situation where water build-up can occur during
operation, a siphon is to be installed in order to ensure
fault-free water drainage, to prevent odour build-up and
to avoid leaks or leak air intake from the condensation
drain. This applies to both the suction and the pressure
sides.
We recommend using a ball siphon on the suction side
and a normal siphon (ball removed) on the pressure side.
The siphon height should be accurately determined,
dependent upon the pressure head.
Every siphon must empty freely over a collector line
funnel.
Horizontal drainage pipes must have a sufficient diameter
and slope gradient, as well as ventilation and bleed prop-
erties for fault-free water drainage.
Other drain pipes (e.g. cleaning tanks) are to be outfitted
with individual stop valves if these are connected to the
drainage system.
The drainage pipes should not be joined in front of the
siphon or stop valve.
Assembly and layout should be in accordance with the
enclosed siphon installation instructions.

4.17 Gas surface burner
The regulations and manufacturer's guidelines applicable
to burners and gas connections must be observed.
When installing the equipment, possible requirements
from the certifying authorities as well as local and national
regulations, must be adhered to.
4.18 Direct lighted burner
The burner must be secured to the prescribed burner
attachment plate.
The flame tube length for oil or gas burners must be
adapted to the warm air generator burner chamber in
such a manner that the flame exits the flame tube only
after it is inside the burner chamber.
The burner must be built in with a natural incline towards
the condensation drain. Condensation water must not
remain inside the heater coil, and the condensation drain
must not be blocked.
The secure temperature limiter must be mounted 500-
1000 mm after the heater in the air direction.
The manufacturer's guidelines applicable to the burner,
condensation drain, fresh air supply and chimney must be
observed.
When installing the equipment, possible requirements
from the certifying authorities as well as local and national
regulations, must be adhered to.
The company reserves the right to make design changes without prior notice.
