Burner description

MULTIFLAM PRE burners are progressive
electronic fully automatic monoblock
devices. Burner head is designed to get
the lowest emissions in terms of NOx and
unburnt particles in order to maximize the
heat generator efficiency. Emissions can
be different respect to the ones recorded in
the lab because they depends a lot on the
generator on which the burner is fit.

The installer must comply with compulsory
rules. Avoid for instance dangerous
atmosphere or not ventilated rooms.

Packaging and handling

Move the burner still in its packaging using
a trolley or forklift, taking care not to drop it
and elevating it no more than 20cm from
ground level. After having removed the
packaging, check that the contents are in
good condition and correspond with what
was ordered. If in doubt, contact the
manufacturer.

The burner must be installed by a
qualified individual.

If the weight and dimensions do not allow
for manual lifting, ask another operator for

help or use a forklift, harness the burner
using belts if no eyebolts are available.

Use the accessories provided
(flange, gasket, pins and nuts) to
install the burner onto the boiler,
taking care not to damage the

isolating gasket.

We can accept no warranty liability
whatsoever for loss, damage or injury
caused by any of the following:

- Inappropriate use.
- Incorrect assembly or repair by the

customer or any third party, including the
fitting of non-original parts.

- non authorised modifications made on 

the burner.

Provision of the system and the
operating instructions

The firing system manufacturer must
supply the operator of the system with
operating and maintenance instructions on
or before final delivery. These instructions
should be displayed in a prominent
location at the point of installation of the
heat generator, and should include the
address and telephone number of the
nearest customer service centre.

Notes for the operator

The system should be inspected by a
specialist at least once a year. It is
advisable to take out a maintenance
contract to guarantee regular servicing.

Adequate ventilation must be provided at
the place of installation of the furnace
system to ensure a reliable supply with
combustion air.

General regulations applying to the
gas connection

• The gas train must only be connected to 

the gas mains by a recognised 
specialist.

• The cross-section of the gas line should 

be of a size designed to guarantee that 
the gas flow pressure does not drop 
below the specified level.

• A manual shut-off valve (not supplied)

must be fi tted upstream of the gas train.
