Spare parts list1 REPLACEMENT PARTS CATALOGUE
This catalogue includes all the replacement parts required for themain-tenance and service of Biasi boilers. Thisedition of the cataloguesuper-sedes all previous editions.
2 MODELS AND SPECIFICATIONS
Biasi produces a number of boilers to satisfy awide rangeof user needsand installation requirements.
All boilers arewallmounted, with instantaneous operation andmodula-ting heat regulation; that is, the amount of heat from gas combustion isautomatically varied according to the heat required by the heating sy-stem.
Biasi boilers differ in four basic characteristics:
2.1 Maximum useful heating power during operation as abuilding heat source
Themodels are available with different maximum useful heating powerwhen used as a building heat source. Each of thesemodels is identifiedby its own model number:
Models 24, 28, 32
2.2 Fume exhaust method
The fumes in the combustion chamber can be exhausted in one of twodifferent ways:
A --- Natural drafting (by the atmosphere)
boilers using this system must be connected to an adequately---sizedexhaust duct system(chimney), anduse air from the installation area forcombustion. Boilers using this system are identified by the letter ”A” intheir model number.
B --- Forced exhaust from a sealed combustion chamber
These boilers are equipped with a fan which forces the fumes throughan adequately---sized exhaust duct system; however, the combustionchamber is enclosed in a sealed chamber and is isolated from the in-stallation area. boilers using this system are identified by the letter ”S”in their model number, and do not use air from the installation area forcombustion.
3 MODEL IDENTIFICATION CODE/SERIALNUMBER
Every boiler produced by Biasi carries its own model identification co-de/serial number.
It is important for the service centre to mention this number when con-tacting the factory (the number must be listed on guarantee claims andservice reports; when making requests for technical information, etc.).
The following is a breakdown of the model identification code/serialnumber and its meaning (reading from left to right):
A) The maximum useful heating power during operation as a buildingheat source (see 2.1).
B) The type of boiler according to its functions (see 2.2)
C) The type of gas used by this boiler. The letter “N” is used for Naturalgas; the letter “G” is used for liquefied petroleum gas (LPG).
D) The first five numbers are the actual serial number.
E) The last four numbers indicate the month (first two numbers) andthe year of construction.
These numbers are used in this catalogue to distinguish betweenversions of the same model with different modifications.
A) Maximumuseful heatingpower duringoperation as abuilding heatsource
B) Type of boiler D) Serial number
E) Month and yearof construction
C) Type of gas usedby this boiler

4 REPLACEMENT PARTS CODE
Each currently available replacement part is uniquely identified by itsown replacement parts code. The replacement parts code consists ofa table code and a position code.
4.1 Table codeThe table code is a sequence of letters and numbers which uniquelyand clearly identify each table. The table code can be found on theupper right of each table (see 4.3).
A validity chart for the table is located at the bottom of the table. Thischart lists the models covered by the table.
M90B.24S M90B.24AM90B.28S M90B.28A
4.2 Position CodeThe position code is a number which is used to identify a particular ob-ject on the table.
Tomake identification easier, position codes for kits have a different for-mat from position codes for individual parts.
515 125Position code for a kit(or assembly)
Position code for anindividual part
A label can be found next to the position code. This label is used to pro-vide additional information on the replacement part and makes identifi-cation of the part easier:
A --- Type of gas
G20 = Methane (natural gas)
G30 --- G31 =Butane---Propane
515 G20 G20125
515 G30---G31 G30---G31125
B --- Validity restrictions
For model 24 KW, only
For mixed--- type models (M90B.24AM90B.28A), only
515 (24) (24)125
515 (A) (A)125
4.3 Composition of the replacement part codeEach replacement part code includes a table identification code and aposition code. A position code is only listed for replacement partswhichare currently available.
The replacement part code consists of the table code (which can befound on the upper right of the table) plus the position code (in two for-mats: individual part or kit).

Replacement part number
The components of a kit are enclosed in a broken line. A kit may containother complete kits, or portions of other kits.In some tables, a replacement part may be identified with an arrow anda complete replacement part code (table code + position code). Thismeans that the part is available, but must be ordered with the codelisted. Also, any explanatory notes must be read before ordering.
