Instructions Prior To Installation; Instructions Prior To Commissioning - Baxi Luna 3 Avant Series Instructions For The User And The Installer

1. INSTRUCTIONS PRIOR TO INSTALLATION

This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler must be con-
nected to a central heating system and to a domestic hot water supply system in compliance with its performances and
output power.
Have the boiler installed by a Qualifi ed Service Engineer and ensure the following operations are accomplished:
a) careful checking that the boiler is fi t for operation with the type of gas available. For more details see the notice on the
packaging and the label on the appliance itself.
b) careful checking that the fl ue terminal draft is appropriate; that the terminal is not obstructed and that no other appliance
exhaust gases are expelled through the same fl ue duct, unless the fl ue is especially designed to collect the exhaust gas
coming from more than one appliance, in conformity with the laws and regulations in force.
c) careful checking that, in case the fl ue has been connected to pre-existing fl ue ducts, thorough cleaning has been carried
out in that residual combustion products may come off during operation of the boiler and obstruct the fl ue duct.
d) to ensure correct operation of the appliance and avoid invalidating the guarantee, observe the following precautions:
1. Hot water circuit:
1.1. If the water hardness is greater than 20 °F (1 °F = 10 mg calcium carbonate per litre of water) a polyphosphate or
comparable treatment system responding to current regulations.
1.2. Domestic Hot Water circuit must be thoroughly fl ushed after the installation of the appliance and before its use.
2. Heating circuit
2.1. new system
Before proceeding with installation of the boiler, the system must be cleaned and fl ushed out thoroughly to elimi-
nate residual thread-cutting swarf, solder and solvents if any, using suitable proprietary products. To avoid damag-
ing metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non alkaline. The recommended
products for cleaning are: SENTINEL X300 or X400 and FERNOX heating circuit restore. To use this product pro-
ceeding strictly in accordance with the maker's directions.
2.2. existing system
Before proceeding with installation of the boiler, the system must be cleaned and fl ushed out to remove sludge and
contaminants, using suitable proprietary products as described in section 2.1. To avoid damaging metal, plastic
and rubber parts, use only neutral cleaners, i.e. non-acid and non-alkaline such as SENTINEL X100 and FERNOX
heating circuit protective. To use this product proceeding strictly in accordance with the maker's directions. Re-
member that the presence of foreign matter in the heating system can adversely affect the operation of the boiler
(e.g. overheating and noisy operation of the heat exchanger).
Failure to observe the above will render the guarantee null and void.

2. INSTRUCTIONS PRIOR TO COMMISSIONING

Initial lighting of the boiler must be carried out by a licensed technician. Ensure the following operations are carried out:
a) compliance of boiler parameters with (electricity, water, gas) supply systems settings.
b) compliance of installation with the laws and regulations in force.
c) appropriate connection to the power supply and grounding of the appliance.
Failure to observe the above will render the guarantee null and void.
Prior to commissioning remove the protective plastic coating from the unit. Do not use any tools or abrasive detergents as
you may spoil the painted surfaces.
