In this case, the Potterton Commercial Engineer must:
• Advise the user/installation technician of any installation anomaly.
•
Inform the user/installation technician of any situation that is deemed to be
hazardous for the appliance and for people.
• Inform of any missing documentation relative to the plant.
• Indicate, in relation to the reports made, any corrective measures to be taken on the
plant which the installation technician will have to carry out in order to proceed with
the operation of "initial activation".
It is the responsibility of the user/installation technician to carry out any corrective
measures on the plant indicated by the Potterton Commercial Engineer. Following such
corrective measures performed by the installation technician, the Potterton Commercial
Engineer will assess the plant again. At this point, if, in the opinion of the Potterton
Commercial Engineer, safety and compliance conditions exist, the Potterton Commercial
Engineer must carry out the "initial activation".
Plant situations that are hazardous for people and for the appliance.
If one of the following hazardous situations arises, the Potterton Commercial Engineer
must not carry out the "initial activation":
• Appliance installed indoors;
• Appliance installed too near combustible surfaces or in any case in conditions that
do not permit access and maintenance operations in safety;
• Control of switching on and off of the appliance not via the CCP/DDC or consent
switch but via the master power switch;
• Situations attributable to defects or failures of the appliance that took place during
its transport or installation;
• Smell of gas due to probable leaks from the plant itself and in any case all situations
that are due to non-compliant plants, considered potentially hazardous.
Anomalous plant situations.
If one of the following situations exists, the Potterton Commercial Engineer may carry out
the "initial activation" at their discretion, but the appliance will be left off until conditions
dictated by the manufacturer are restored:
•
Installations (potentially not hazardous) not carried out according to good
workmanship practices, not complying with current national and local regulations;
•
Installations (potentially not hazardous) not carried out according to good
workmanship practices, not complying with the instructions supplied by the
manufacturer;
• Installations that can lead to operating anomalies of the appliance.
Checking and adjusting the combustion parameters
During the initial activation procedure, the combustion parameters must be checked
and set ONLY by a Potterton Commercial Engineer. In this stage, NEITHER the user NOR
the installation technician is authorised to perform such operations, and in so doing may
invalidate the guaranty of the appliance.
The appliance is supplied with all of its units already regulated for the type of gas for
which the appliance itself is set up.
The type of gas for which the appliance is set up can be identifi ed from the adhesive label
located on the unit's internal gas pipe (see detail M, Figure 6.2 Gas changeover on page
63).
The appliance is supplied with the nozzles required to make the gas type change to G30
and G31.
