Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

Look for the code N911650201 (it can also be seen as 911650201, N 911650201, or N-911650201) and, in the engine, N412003525.
Compare model E18C0090NH, type EV100M/C/G/120/E18CO + hall and data 230 V, 50 Hz and 42 W.
Do not use the individual number 10238698: it belongs to this unit. Also, do not confuse the S1008800 (without tachometer, Thema F 24 E) with this assembly with hall sensor.
Check the model on your boiler's label: the confirmed one is the Saunier Duval Thema F24 NOX. In another boiler, see if its parts list includes 035003719.
If they match, call us at 911 17 77 77 with your boiler model and we will reserve it for you.

Diagnosis and fault codes

Symptoms that require diagnosis in the extractor

The extractor evacuates the combustion gases with forced draft. These are the typical symptoms and what to do:

Common symptoms and faults

01
The boiler shuts down due to flue gas failure.
Cause: The extractor is one of the parts to check.
Ask an installer to check the extractor. Before replacing it, compare the codes N911650201 and N412003525 of your part with those of this extractor.
02
The extractor fan is making noise.
Cause: The extractor fan is one of the parts to check.
With the boiler disconnected from the power supply, an installer can check the status of the fan. Compare the label of your spare part with that of this extractor before ordering it.
03
The boiler stops with fault code F32: fan or air extraction failure.
Cause: Blocked or poorly connected fan, electronic fault, or obstructed flue.
Have a technician check the fan, its connector, and the flue.

Códigos de error SIT que requieren diagnóstico

Code	Fault	Technical checks
F32	Fan or air extraction fault.	Have a technician check it: it could be a blocked fan, its connector, or a blocked flue.

These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.

Before purchasing

To confirm: Hermann Supermicra Ecoplus 24 SE — they provide the code 035003719 for the Supermicra (written as 35003719; 24 SE in ); no reference N911650201.
To confirm: Hermann Supermaster Inox 24 SE Ecoplus — da 35003719; does not mention N911650201.
Do not confuse: S1008800 — Extractor "without tachometer" that Registered designation: the Thema F 24 E — This unit has hall sensor (+hall) and the Thema F 24 E is not the F24 NOX: do not assume they are the same part.
10238698 is the individual number printed on this unit, not a reference: it cannot be used to search for the spare part.
To confirm: they mention N911650201 with the fan EV100M. They link 035003719 to E18C0090NH or LNE18C0090NH; it gives 035003719 and 35003719 for the Thema NOx F24. No official breakdown. The boiler is confirmed.

Frequently Asked Questions

Frequently asked questions about the extractor

How do I identify the extractor SIT N911650201?

In our unit, the assembly is marked N911650201 (it can also be seen as 911650201, N 911650201, or N-911650201), the motor N412003525, and the model E18C0090NH / EV100M/C/G/120/E18CO + hall. The label indicates 230 V AC, 50 Hz, and 42 W. Compare those codes with your spare part.

Is it compatible with my Saunier Duval Thema F24 NOX?

Yes. Confirmed: for the Thema F24 NOX. Additionally, they provide the fan (035003719, 35003719) for that boiler. The Italian ones link 035003719 to this SIT assembly. Not confirmed: N911650201 along with the boiler, and we have not read an official parts list.

What do N911650201, N412003525, and E18C0090NH mean?

According to the label, N911650201 is the code for the extraction assembly, N412003525 is the code for the mounted motor (not the reference for the extractor), and E18C0090NH is the model of the casing. E18C0090NH is given as the model of the fan and SIT S.p.A. as the manufacturer of the motor. With N911650201, they write the type EV100M/C/G/120E or EV 100M / G / C / 120 / E18CO + hall.

Is it the same as the fan 035003719 from Hermann / Saunier Duval?

To confirm: yes: it gives 035003719 for the E18C0090NH EV100M + hall and gives H035003719 for the EV100/M LNE18C0090NH. It catalogs it with its code of H035003719/SD alongside N911650201. This information is: an official breakdown is missing.

In which other boilers is this fan used?

The 035003719 (write 35003719) is also mentioned for the Hermann Supermicra Ecoplus 24 SE (and they only say Supermicra) and the Hermann Supermaster Inox 24 SE Ecoplus. Compatibility to be confirmed: none mentions N911650201.

Does it operate at 50 Hz or 60 Hz, and how many watts does it have?

The label on our unit states 230 V AC, 50 Hz, and 42 W; it gives 42 W; it gives 230 V, 50 Hz, and 43 W. It writes 60 Hz, which does not match the label: in this unit, it is 50 Hz.

Who should install the extractor?

A qualified technician: it is a 230 V fan in the flue gas exhaust of a gas boiler. Disconnect the boiler from the power supply before touching it and compare N911650201 and N412003525 with those of your part.
