General Description Model FLE Assembly

3. Order of Assembly
The assembly of the pressure vessel and casing will
be easier if all of the component parts are sorted
and arranged to be easily accessible in the working
area. If there is not enough room in the work area
for all the parts, only those that will be needed for
the day’s work should be brought into the work
area.
Assembly of the boiler can be regarded as a four
step process. The four steps are:
1. Pressure vessel assembly and
water side leak test (Chapter 2)
2. Casing assembly and fireside leak
test (Chapter 3)
3. Burner assembly and gas train
installation (Chapter 4)
4. Trim installation (Chapter
4)
The boiler components are listed in Table 1-1.
Special assembly equipment likely to be required for
each part of the assembly process is listed below.
There are three different types of insulation used in
the construction of the Cleaver-Brooks Flextube
Model boilers:
• Ceramic fiber- white, flexible, dry insulation, supplied
in bulk roll or block
• Wet-pack- white, flexible, insulation saturated with
curing agent, supplied as rolls in sealed bags
• Fibrefax- white insulation, supplied in tubes
