Introduction - Baxi LUNA HT 1.1000 Notice D'installation Et D'entretien

WARNING
Verify proper operation after servicing.
CONDENSATE REMOVAL SYSTEM
This is a condensing high efficiency appliance; therefore this unit has a condensate removal system. Condensate is
nothing more than water vapor, derived from the combustion products. It is very important that the condensate line is
sloped away from the boiler and down to a suitable inside drain. A condensate filter, if required by local authorities can be
made up of lime crystals; marble or phosphate chips that will neutralize the condensate. This can be done in the field by
the installer. It is also very important that the condensate line is not exposed to freezing temperatures, or any other type
of blockage. Plastic tubing must be the only material used for the condensate line. Steel, brass, copper or others will be
subject to corrosion or deterioration. A second vent may be necessary to prevent condensate line vacuum lock if a long
horizontal run is used. Also, an increase in pipe size may be necessary to drain properly. Support of the condensation line
may be necessary to avoid blockage of the condensate flow.
CAUTION
The condensate line must remain unobstructed, allowing free flow of condensate. If condensate is allowed to
freeze in the line or if the line is obstructed in any other manner, condensate can exit from the boiler condensate
trap, resulting in potential water damage to property.
Note:
Use materials approved by the authority having jurisdiction. In the absence of other authority, PVC and CPVC pipe must
comply with ASTMD1785, F441 or D2665. Cement and primer must comply with ASTM D2564 or F493. For Canada, use
CSA or ULC certified PVC or CPVC pipe, fittings and cement. When installing a condensate pump, select one approved
for use with condensing boilers and furnaces. The pump should have an overflow switch to prevent property damage
from condensate spillage. Condensate from the Boiler will be slightly acidic (typically with a pH from 3.0 to 4.0). Install a
neutralizing filter if required by local codes.
The Condensing HT boiler is a wall hung, fan assisted room-sealed combination boiler.
The boiler is provided with central heating and is designed for use with a fully pumped, sealed and pressurised heating
system.
As supplied, the boiler will automatically modulate to provide central heating outputs as shown in Section 2.1.
WARNING
It is the law that all gas appliances are installed by a competent person.
It is in your own interest and that of safety to ensure that the law is complied with.
• The installation must conform to the requirements of the authority having jurisdiction or, in the absence of such requi-
rements, to the National Fuel Gas Code, ANSI Z223.1/NFPA 54
Where required by the authority having jurisdiction, the installation must conform to the Standard for Controls and
Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.
Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on boiler
when boiler underwent tests specified in ANSI Z21.13-latest edition.
• The installation should conform with CSA B149.1 INSTALLATION CODE and/or local installation Code, plumbing or
waste water codes and other codes as applicable.
• Clearances from and protection of combustible material.
• Manufacturer's instructions must NOT be taken in anyway as over-riding statutory obligations.
