6.3. Hydraulic connection
6.3.1. General notice
For the hydraulic connection of the heating system and water heaters– in particular with regards to technical
safety devices such as safety valves, expansion tanks, etc. – refer to generally accepted engineering rules as well
as locally applicable standards, specifications and regulations.
If boilers are installed in
garret-based heating plants or at the highest point of the heating system, then boilers
will have to be provided with additional safety devices (such as protections against water shortage). Observe the
minimum operating pressure as specified in chapter 4.2. Act in compliance with local safety regulations in force at
all times.
Before connecting the boiler to an
old installation, it is necessary to flush the whole heating system. It is also
recommended to provide for a sludge separator.
To protect the boiler from return temperatures below the limits as specified in chapter 4.1, the boiler should be
provided with an automatic return temperature regulation.
If the Pyronox LR/LRK boilers are combined with a
water heater, make sure that their size and capacity
correspond to the installed boiler capacity.
A component-tested membrane safety valve must be used to reliably prevent the permitted operating
overpressure in the water heater from being exceeded; it must not be possible to shut the valve off from the water
heater.
When water heaters with an electrical auxiliary heater are used, a reliable check valve must be installed in the
charging tube between the boiler and the water heater.
Boiler’s maximum operating pressure and the maximum operating temperature are indicated in chapter 4.1.
No minimum level of the amount of circulating water is required.
Damage can occur from
corrosion when oxygen continuously enters the heating water through open installations,
expansion tanks that are too small, floor heaters with pipe material that is not oxygen-tight, etc.
If this cannot be prevented, additional measures are necessary in the form of correctly used oxygen binding
agents or chemicals. If it is not possible to realize an installation without oxygen entrance, a
system separation
must be set up using heat exchangers.
6.3.2. Special notes for Pyronox LRK, LRK-NT:
6.3.2.1. Water flow rate
It is recommended to select the water flow rate of the recuperator as high as possible (see chapter 4.7).
Important:
The boiler may not be put into operation before the recuperator has been connected and is flushed with water.
Furthermore, if no condensation is desired, such as in the case of oil operation, the customer must ensure that the
inlet water in the recuperator is kept at an adequate temperature (min. 50°C) at all times.
6.3.2.2. Draining the condensate
The condensates that result during condensation contain combustion products that are more or less acidic,
depending on the fuel type. Any necessary approval for draining the condensate into the sewer system must be
obtained from local authorities.
A condensate neutralisation set is available as an option, if desired.
If the condensate is drained directly into the sewer system, then this must take place via an open funnel/hopper.
The line to the funnel/hopper must have a slight gradient and should not show any slack.
Important:
The recuperator is delivered with a siphon arranged in the casing. It must be ensured that no additional siphon is
installed since this would prevent the condensate from draining away.
