The combustion product extraction duct must be dimensioned by
using the parameters set out in the table in chapter 3.3.
Depending on the actual confi guration of the duct, a calculation is
required to check that the pressures at the boiler outlet do not exceed
the maximum allowable values (200 Pa).
Values corresponding to the 50/30°C regime are to be used for this
calculation.

4.16. Hydraulic connection
A water circulation pump integrated into each generator and a smart
regulation logic enable optimum operation up to Pinst/30 (Pinst =
Instant output power expressed as Th/h - 1Th/h = 1.163 kW).
Below this rate of Pinst/30, the generators will continue to operate, but
will gradually reduce their power (shutdown below Pinst/46).
In the main exchanger, as in the condenser on each generator, you must
ensure that the rates recommended in paragraph 3.4 are not exceeded
(i.e. Output power in nominal Th/h generator / 10).
MODELS
780 -- 1 to 100
900 -- 1 to 100
Therefore, a differential pressure valve must be integrated into
the circuit according to the diagam.
Sizing the pipes connecting the boiler to the installation must be done
carefully, to minimise the pressure losses and so avoid oversized circulating
pumps.
In some cases the diameter of the connection pipes will be greater than the
diameter of the boiler tappings. The diameter increase can then be made
advantageously after the union connectors, the stop valves, and/or the
hydraulic balancing valves.
Tichelmann assembly encourages a natural balance of the fl ow rate between
the 2 generators.
The VARMAX TWIN boilers are equipped with the following elements:
• A drainage valve on each generator's main exchanger,
• A drainage valve on each generator's condenser.
Edition: 02 / 2015 Page 19 / 56

In accordance with the diagram, it is imperative to fi t the boiler and its
installation with the following components:

VARMAX TWIN optimisation:
The Varmax Twin may be optimised as necessary using the parameters in the Flow menu. Refer to
the NAVISTEM B3000 boiler's controller manual for more details.
Maintenance optimisation
A maintenance message may be generated that does not set the generator to fault. This maintenance
message may be displayed after the following 3 counters have expired:
• Time since last maintenance (or commissioning): set parameter 7044 to 12 months
(Maintenance / Special regime menu)
• Burner's operating hours (parameter 7040 - menu Maintenance / Special regime menu)
• Number of starts (parameter 7042 - menu Maintenance / Special regime menu)
These last 2 parameters are dependent on the boiler's hydraulic installation. We recommend
using at least parameter 7044 for annual maintenance.

VARMAX TWIN optimisation:
The Varmax Twin may be optimised as necessary using the parameters in the Flow menu. Refer to
the NAVISTEM B3000 boiler's controller manual for more details.
Maintenance optimisation
A maintenance message may be generated that does not set the generator to fault. This maintenance
message may be displayed after the following 3 counters have expired:
• Time since last maintenance (or commissioning): set parameter 7044 to 12 months
(Maintenance / Special regime menu)
• Burner's operating hours (parameter 7040 - menu Maintenance / Special regime menu)
• Number of starts (parameter 7042 - menu Maintenance / Special regime menu)
These last 2 parameters are dependent on the boiler's hydraulic installation. We recommend
using at least parameter 7044 for annual maintenance.
