Using The Boiler - Biasi GARDA HE SYSTEM M96.28SR/P User Manual And Installation Instructions

Congratulations on your choice.
PARVA HE are condensing high efficiency sealed chamber fan flue gas boilers.
They are fully electronically controlled and have electronic ignition.
The materials they are made of and the control systems they are equipped with give you safety,
a high level of comfort and energy savings to allow you to get the greatest benefit out of
independent heating.
PARVA HE allow a higher efficiency by reducing the flue gas temperature such that the water
vapour formed during the combustion is condensed out.
This allows a gain of useful heat that otherwise would be lost.
Remember that...
n The manual
--- must be read thoroughly, so that you will
be able to use the boiler in a safe and sen-
sible way;
--- must be carefully kept. It may be necess-
ary for reference in the future.
First lighting up must be carried out by
n
competent and responsible engineer.
n The manufacturer
--- disclaim all liability for any translations of
the present manual from which incorrect in-
terpretation may occur
--- cannot be held responsible for non ---ob-
servance of instructions contained in this
manual or for the consequences of any pro-
cedure not specifically described.

Using the boiler...

Before lighting the boiler you are ad-
n
vised to have a professionally qualified per-
son check that the installation of the gas
supply
--- is gas---tight;
--- is of the correct gauge for the flow to the
boiler;
--- is fitted with all the safety and control de-
vices required by the current Regulations.
n Ensure that
--- the installer has connected the pressure
relief valve outlet to a drain pipe. The manu-
facturers are not responsible for damage
caused by opening of the pressure relief
valve and consequent escape of water, if not
connected correctly to the drain.
--- the installer has connected the conden-
sate outlet to a suitable drain pipe.
n On detecting the smell of gas
--- don't operate any electrical switches, the
telephone or any device that may produce
sparks;
--- open the windows and doors at once to
create a draught of air which will purge the
area;
--- shut off the gas cocks;
--- get the assistance of a qualified person.
n Do not touch the appliance with parts of
the body that are wet or damp and/or bare
feet.
n Do not block or modify the condensate
outlet and pipework
n In case of structural work or mainten-
ance near the exhaust duct and/or fume ex-
haust devices or their attachments, turn off
the appliance. On completion of the work,
have a professionally qualified person check
their efficiency.
Repairs (under guarantee) must be car-
n
ried out only by an approved engineer, using
genuine spare parts. Thus do no more than
switching off the boiler yourself (see the in-
structions).
Your boiler allows heating up of water to
n
a temperature less than boiling point;
--- must be connected to a central heating
system and/or a hot water supply system,
compatible with its performance and output;
