Venting Instructions - Baxi LUNA HT 1.450 Installation And Servicing Instructions

INSTALLING EXHAUST VENT AND INTAKE AIR VENT
DANGER
Ensure that the flow of combustion and ventilation air are not obstructed.
BAXI urges users to install CO detectors in buildings where the boiler is located, even though such detec-
tors may not be required by local law. The CO detectors should be calibrated regularly as specified by the
manufacturer.
Note:
To fix flue pipes to the wall, supports should be approximately 3.28 feet (1.0 meter) from each other. Supports should be
fixed along the joint point of each pipe.
4.1.1 Concentric venting
1. Examine all components for possible shipping damage, prior to installation.
2. This venting system must be free to expand and contract.
3. The venting system must be supported in accordance with these instructions.
4. The vent system must have unrestricted movement through walls, ceilings and roof penetrations.
5. Check for proper joint construction when joining pipe to fittings.
6. If venting is penetrating ceilings and floors, the openings must have firestopping provided in joist areas and the
installation of firestop spacer assemblies.
7. Roof flashing parts are shown in the manual. Standard roof flashing methods should be employed to install roof
flashing.
8. Except for installation in single and two-family dwellings, metal venting systems which extend through any storey
above that on which the boiler is located are to be provided with enclosures having a fire resistance equal to or
greater than that of the floor or roof assembly through which they pass.
9. Wall and roof openings must be framed to provide support and the attachment of termination assemblies.
Please Note:
The manual uses the terms 'vent', 'venting' and 'flue' interchangeably. All references to 'flue' are synonymous with
'vent' or 'venting'.
WARNING
Check all measurements before cutting. Clearance to combustible materials when using a concentric vent system
is zero.
