Gas condensing boiler TRIGON XXL

Technical description

Technical Description

The TRIGON XXL is a fully modulating
condensing boiler. The control unit of
the boiler adapts the modulation ratio
automatically to the heat demand re­quested by the system. This is done by
controlling the speed of the fan. As a
result, the whirlwind mixing system will
adapt the gas ratio to the chosen fan
speed, in order to maintain the best
possible combustion figures and there­with the best efficiency. The flue gases
created by the combustion are trans­ported downwards through the boiler
and leave at the back side into the

chimney connection.

The return water from the system en­ters the boiler in the lower section,
where is the lowest flue gas tempera­ture in the boiler. In this section con­densation takes place. The water is
being transported upwards through the
boiler, in order to leave the boiler at the
top (burner) section. The cross flow
working principle (water up, flue gas
down) ensures the most efficient com­bustion results.

The LMS14 control unit can con­trol the boiler operation based on:

 Boiler control (stand alone

operation);

 weather compensated operati-

on (with optional outdoor sen­sor);

 With 0-10V external influence

(temperature or capacity) from
a building management sys­tem.

General regulations

This documentation contains
important information, which is a base
for safe and reliable installation, com­missioning and operation of the boiler.
All activities described in this document
may only be excecuted by authorized
companies.

Changes to this document may be
effected without prior notice. We accept
no obligation to adapt previously delive­red products to incorporate such chan­ges.

Only original spare parts may be used
when replacing components on the
boiler, otherwise warranty will be void.

Norms and regulations

Maintenance
Fuel
Combustion air
Water quality

Maintenance

Regular maintenance is necessary to
secure a safe and economical operati­on of the installation. For the TRIGON
XXL, one annual maintenance visit is
recommended. During this visit, the
proper functioning of the complete hea­ting system should be checked as well.

Water quality

The lifetime of the complete heating
system is affected by the water quality.
Additional costs for water treatment of
an installation are always lower than
repairing costs for damage created by
poor water quality.

Fuel

The gas condensing boiler TRIGON
XXL is applicable for gases G20, G25,
G30 and G31. Factory settings are al­ways done for G20. For other types of
natural gas, a correction can be made
on the gas valve. For LPG, it’s neces­sary to fit a restriction plate (included in
delivery) before operating the boiler.

The TRIGON XXL can work with gas
pressures up to 100 mbar. In case of a
gas pressure above 100 mbar, a pres­sure regulator should be fitted in the
gas line (available as accessory).

The gas consumption and gas pres­sures of the different gases can be
found in the chapter „Technical data“.

Combustion air

The gas condensing boiler TRIGON
XXL can be used in both non­roomsealed and roomsealed applica­tions. The combustion air to the boiler
shouldn’t contain high concentrations of
dust and/or halogen, as they can dama­ge the heat exchanger surface. Especi­ally in buildings, where chemicals are
used, the combustion air facility should
prevent these chemicals to enter the
boiler.

The different room sealed connection
possibilities the TRIGON XXL is
approved for, can be found in the
chapter „Flue gas system“.

The following water quality levels must
be respected at all times for warranty
claiming. Damage to the boiler due to
poor water quality will not be taken un­der warranty.

The system should be filled with water
with a PH value between 7,0 and 9,5.
The chloride -, sulphide - and nitride
value of the water should not exceed
50 mg/l. Entry of oxygene by diffusion
should be prevented at all times.
Damage to the heat exchanger
because of oxygene diffusion will not
be taken under warranty.

In installations with higher water
volumes, it’s necessary to respect the
maximum filling and additional volumes
with corresponding hardness values as
stated in the german VDI2035
standard. In the table you can find the
nominal values for filling and additional
water for the TRIGON XXL according to
the the VDI2035.

The table at the left gives an indication
of the relation between the water
quality and the maximum water filling
volume during the lifetime of the boiler.
Consult the original text of the VDI2035
for more detailed information.

Constant entry of oxygene in the
installation should be avoided. The
system water pressure should be
higher than the atmospheric pressure in
all parts of the installation. Underfloor
heating components without oxygen
diffusion barrier should never be used.
When they’re used anyway, a system
separation (e.g. with plate heat
exchanger) is compulsory.

Noise protection
Antifreeze

Noise protection

The gas condensing boiler TRIGON
XXL is equipped with a patented
premix burner. The noise level of this
very quiet premix burner is extremely
low in comparison to conventional gas
burners. Therefore no further mea­sures have to be taken for noise pro­tection in the boiler room.

Antifreeze

The TRIGON XXL can be used with the
antifreeze type Shell Antifreeze Con­centrate. The concentration of the anti­freeze in the system affects the maxi­mum capacity the boiler can work on.
The relation between antifreeze con­centration and capacity reduction of the
boiler can be found in the graph.
The maximum percentage of antifreeze
should not exceed 30%.

The TRIGON XXL is supplied with ad­justable wheels, which also prevent the
transmission of vibration noise from the
boiler into the building.

Once the boiler is in the correct positi­on, turn anti-clockwise the regulator (A)
or the nut (B) to let the feet out, till the
boiler is set in the right height.

Noise created by system components
(e.g. pumps) should be taken care of
with external measurements, in case of
higher noise level requirements.

Flue gas system

Requirements and regulations
Materials

Requirements and regulations

Regulations for the construction of flue
gas systems are very different for each
country. It should be ensured that all
national regulations with regard to flue
gas systems are respected. The most
important national norms can be found
in the chapter „Norms“.

A separate condensate drain for the
chimney is not necessary, as the con­densate can enter the drain via the
syphon connection of the boiler.

Materials

Exclusively materials, which are heat
resistant and resistant to flue gases and
aggressive condensate, may be used.

The TRIGON XXL has an integrated high
limit thermostat function for the flue gaes.
When the fluegas temperature exceeds
100ºC, the burner is switched off. With
this function, an additional (external) sa­fety device is not necessary.

Flue gas system

Dimensioning

Dimensioning

When dimensioning a flue gas system, it’s necessary to perform a calculation
check of the flue gas system in order to verify if the choosen system is applicable.

The following tables represent as an example of possible flue gas systems of TRI­GON XXL SE, EVO and ECO series, including the maximum possible height of
the system. These examples only give an indication of the possible heights, but
they can not be used for official flue gas layout calculation. Each flue gas system
must be calculated by an authorized company.

The maximum negative flue gas pressure, which doesn’t affect the burner modula­tion ratio, is 30 Pa. Higher negative pressure will lead to limitation of the burner
modulation ratio.

The maximum horizontal flue gas way is 20m. With horizontal ways longer than
20m, a faultless burner start in cold condition can not be guaranteed.

General

Condensate, created by the TRIGON
XXL, should be drained into the public
draining system. The condensate PH is
between 3.0 and 3.5. National and/or
local regulations have to be checked, in
order to find out whether the condensa­te should be neutralised before entering
the public draining system.

Neutralisation systems

The neutralisation systems can be
placed in the bottom section of the boi­ler. The delivery of the system contains
the following components:

 Granulate for first filling
 Connection hoses for inlet and outlet

connection

 Boiler connection adapter

For the neutralisation two different sys­tems are available:

Standard neutralisation system (DN)

The standard neutrlisation system is used, when the public draining connection is
at lower level than the boiler syphon connection.

Neutralisation system with pump (HN)

The neutralisation system with pump is used, when the public draining system is at higher level than the boiler syphon
connection and the condensate needs to be transported to a higher level before draining is possible. The built-in pump of the
neutralisation system takes care of the transport of the condensate.

The maximum amount of condensate
for each boiler type can be found in the
chapter „Technical data“.

Water flow data TRIGON XXL SE

Hydraulic resistance

The hydraulic resistance depends on
the flow rate through the boiler and the
boiler type. In the graph the resistance
for a specific flow rate can be found.

The TRIGON XXL is able to control a
speed controlled pump via PWM or a
0-10VDC signal. It makes the flow rate
modulate in parallel with the burner
load. The minimum flow rate, to which
the pump is allowed to modulate with
the burner load, is 30% of the nominal
flow rate through the boiler for ECO
and EVO versions, and 50% for SE
versions.

The flow rate through the boiler can
also be checked by calculation. This
can be done with a ∆T as well as a ∆p
measurement.

∆T-measurement

Check the temperature difference over
the boiler (∆T flow-return) when the
boiler is running on 100% load. The
nominal ∆T is 20K and must be at least
between 10K and 30K for secure boiler
operation. An indication of the actual
flow rate can be found with the follow­ing calculation (see table below for
nominal data):

∆p-measurement

Check the pressure difference over the
boiler (∆p flow-return) when the boiler
pump is running (burner on is not re­quired). The nominal ∆p for each boiler
type can be found in the table below,
actual ∆p must be within:

0.45*Δp

Hydraulic connection into a system

The TRIGON XXL must be connected
in such a way, that a minimum flow rate
of 50% of the nominal flow rate of SE
versions and 30% of the nominal flow
rate of ECO and EVO version can be
ensured at all times, independent from
the flow rate in the secundary system.
This can be achieved by using one of
the following 3 possibilities:

 Standard, with low loss header or

plate heat exchanger

 Bypass, with integrated minimum flow

rate by Bypass pump*

 Split System, with 2 return connec-

tions for best possible efficiency
(warm and cold return)*

* only applicable in single boiler instal­lations

Standard

This is the most common way to
connect the boiler to the system. By
using a low loss header or plate heat
exchanger a minimum flow rate can be
ensured at all times, independent from
the flow rate in the secundary system.
The boiler pump is available as a speed
controlled version. The speed
controlled pump mudulates the flow
rate in the primary system in parallel
with the burner load. This ensures the
lowest possible return temperature to
the boiler for high efficiency usage.
Details of the available pump kits can
be found in the chapter „Accessories“.

Bypass

In single boiler installations, the TRI­GON XXL can also be used without low
loss header or plate heat exchanger.
For this solution a bypass kit is availab­le as accessory to the standard boiler.
The bypass is connected between the
flow connection and the second return
connection of the boiler.
The performance of the bypass pump is
very low when the system flow rate is
high. As soon as the system flow rate
decreases, the bypass pump perfor­mance increases to ensure a minimum
flow rate through the boiler.

The bypass pump does not transport
the water from the boiler into the
system. The system pump should
overcome the boiler resistance at
nominal flow rate to transport the
from the boiler into the system and
vice versa.

Details of the available pump kits can
be found in the chapter „Accessories“.

Details to the 3 possibilities mentioned
above, can be found in the next sec­tions.

Basic controls and connections

The standard version of the TRIGON
XXL is equipped with a LMS14 boiler
management unit. This controller con­trols both the burner safety operation
and the temperature regulation of the
boiler. The LMS14 includes the follo­wing functions:

 Weather compensation (with optional

outdoor sensor)

 Connection possibility for external

gas valve and/or room fan. See chap­ter "Accessories" for combinations
with an OK/Alarm contact

 Master/Slave cascade control (with

optional BUS communication mo­dules).

When additional control of secundary
heating zones or cascade systems are
required, the TRIGON XXL can be ex­tended with different additional controls.
Explanation of these controls can be
found in the next sections.

 Electronic high limit thermostat
 Electronic flue gas temperature limiter
 Primary boiler pump control (via re-

lay)

 Primary sanitary hot water pump con-

trol
(use of relay necessary when > 1A)

 Interlock input
 Lockout input
 Alarm output signal
 Boiler enable signal
 0-10VDC temperature or capacity

setpoint (programmable)

 0-10VDC capacity feedback or 10V

contact for external gas valve
(programmable)

 Temperature control central heating

via PID controller

 Temperature control sanitary hot wa-

ter (hot water priority)

Control by building managemant
system

The TRIGON XXL can be connected to
a building management system. This
can be done by using (one of) the follo­wing connections:

Boiler enable signal, terminals
116-117 (volt free)

The boiler enable signal is provided
with a jumper from the factory. When
connecting a (volt free!!!) external sig­nal, the jumper must be removed.

Temperature or capacity setpoint,
terminals 112-113 (0-10VDC)

The TRIGON XXL can be controlled via
a temperature or capacity setpoint.
The signal values are programmable,
from the factory the contact is pro­grammed for temperature setpoint with
settings as shown in the graphic.

When controlling the boiler via a capa­city setpoint, it’s highly recommended
to control the primary boiler pump with
the internal pump control of the LMS14
boiler controller. The minimum flow rate
through the boiler must be respected at
all times. The nominal ∆T is 20K and
should be at least within 15K-30K at full
load to secure a safe boiler operation.

Attention: from 0,15V the burner will
work on minimum load.

For room temperature optimisation of
each heating zone, an additional roo­munit QAA75 can be connected via bus
connection. The values for the specific
heating zone can then be displayed
and changed on the room unit.

In case of heating systems with more
than three heating zones, an additonal
kit with Logon B G2Z2 controller in a
wall hung box is available. These kits
can be used in a modular way up to a
maximum of 8 heating zones.

See chapter "Installation examples" for
more details regarding connections of

2-A-C: 1 heating zone + low loss header

Description

 TRIGON XXL with low loss header
 Weather compensated control
 1 mixed heating zone

Tips

 Complete accessory kits with low loss

header are available for ∆T=10-20K
(see chapter „Accessories“).

 The primary circuit should be de-

signed for ∆T=20K, this guarantees a
high boiler efficiency.

 When the secundary circuit is de-

signed for a ∆T smaller than 20K, the
flow temperature in the header will be
lower than the flow temperature of the
boiler. This should be taken in consid­eration during the design stage.

 The header should be positioned

close to the boiler, to avoid a negative
influance on the temperature control
quality.

 In case of a boiler room installed on

the roof, the boiler may never be hy­draulically connected at the highest
point of the installation.
