Installation Information - Flueing
General flueing guidelines
Every appliance requires a flue system that will draw effectively and safely clear flue products
under all wind and climatic conditions.
It is the responsibility of the installer to ensure that the appliance is provided with an effective
flue. Some guidelines to assist with flue design is listed below. These must be read and
modified as necessary with reference to the particular installation.
Flue Terminal Locations
Must be compliant with 'Clearances Required for Flue Terminals' from NZS:5261.2003.
Flue Length
This is required for adequate draw and prevents spill-back of combustion products that can
cause safety sensors to shut down the fire.

Flue Systems
For new fireplace installations (installations into a combustible opening) a Rinnai Zero
Clearance Box and Flue Kit is a mandatory requirement to meet warranty conditions.
For masonry installations, to ensure adequate draw, Rinnai strongly recommends the
use of a Rinnai Flexiliner Flue System. Failure to meet this installation criteria may
result in an unsafe situation. Installation without a flexiliner flue is permissible as long
as the chimney has been checked for soundness and ability to achieve a good draw.
Shared Flues
Gas appliances must not be connected to a chimney or flue serving a separate solid fuel
burning appliance.
Flue Cowl Clearance
To ensure the products of combustion are cleared, adequate clearance from the building is
required. The following guideline is recommended.
Flue cowl should have a 500 mm clearance from any part of the building. This also applies to
steeped and pitched roofs which should be 500 mm clear of the ridge line as shown below.
Lesser clearances may provide perfectly adequate flue systems depending on the installation.
