BOILER REPLACEMENT: MODENA 80/102 TO MODENA C E
Introduction
The new Ferroli Modena C HE high efficiency condensing combination boiler is an ideal replacement
for the earlier non-condensing Modena 80E or Modena 102.
The new Ferroli Modena C HE is smaller, weighs less, has built-in frost protection and an IP
protection rating of IPX5D. This allows direct replacement wherever the existing boiler is legitimately
installed (i.e. Kitchen, Garage, Bathroom, etc.)
Although the actual position of the pipe-work connections differ slightly, the configuration remains
the same, thereby requiring only limited pipe-work alteration.
The electrical connection remains the same, i.e. all models supplied with a factory fitted three core
fly - lead to provide a permanent live connection and all models use the same volt free contacts for
any external system controls.
This guide refers to the fitting of a replacement boiler with a standard horizontal flue application
only (minor adjustments may be necessary for other flue applications – refer to boiler installation
instructions)
The flue outlet connection on the new Modena C HE is centrally aligned and is therefore completely
compatible with the earlier Modena 102. The flue connection on the Modena 80E is to the left of
centre but providing that there is a minimum clearance of 15mm to the left of the existing boiler, no
alteration to the existing flue position is necessary.

Please note:
As with all condensing boilers it is necessary to check
the existing flue terminal position to ensure that the
“plume” from the combustion products will not create a
‘nuisance problem’.
A plume displacement kit is available to overcome any
such problems.
Consideration must also be given for the provision of a
condensate outlet for the new boiler.
The work procedures described in this document must
be completed strictly in accordance with the
manufacturer’s
installation
instructions,
current
regulations and relevant standards, and only by
competent person/persons as stated in the Gas Safety
(Installation & Use) Regulations.
Prior to fitting the replacement boiler the entire system
must be thoroughly cleansed and flushed in accordance
with Building Regulations L1A/L1B & BS 7593.
The Installation must comply with the following

•
