Flue guidelines

Every gas ﬁreplace requires a ﬂue system that will draw effectively and clear ﬂue products

safely under all potential 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 are listed

below. These should be viewed in

conjunction with the installation

instructions provided by the ﬂue

manufacturer (included with

all Rinnai Symmetry ﬂue cowls)

and with the Horizontal Flashing

Kit instructions. These must be

read and modiﬁed as necessary

with reference to the particular

installation

The Rinnai Symmetry RDV3611

must be installed with an

approved Rinnai ﬂue system.

Approved ﬂue components for

this appliance are detailed in this

guide.

Clearance to combustibles

Minimum clearance from inner

ﬂue to combustible material must

be greater than 50 mm—equates

to 15 mm from the outer ﬂue.

Flashings

A Horizontal Flashing Kit is

supplied with the horizontal

ﬂue kits. For all other ﬂueing

conﬁgurations ﬂashings must be

speciﬁed.

Flue cowl clearance

To ensure products of combustion

are cleared, adequate clearance

for the building is required.

The 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 clear of the ridge line

as shown. Lesser clearances

may provide perfectly adequate

ﬂue systems depending on the

installation. Minimum clearances

are shown in NZS 5261.

Flue terminal locations

Must be compliant with

‘Clearances Required for Flue

Terminals’ from NZS 5261 2003.

Flue is not to terminate under

ﬂoors or in a roof space.

Self-supporting ﬂue

The weight of the ﬂue system

should not be supported by the

appliance—it should be self-

supporting. Supporting the ﬂue

is usually completed during the

framing stage with ﬂue supports

or straps within the cavity. Wall

straps have been included in the

Rinnai Vertical Flue Kit to assist

with this. Elbow straps are also

available as a separate component

to prevent excess weight on the

ﬂue elbow.

Shared ﬂues

Gas appliances must not be

connected to a chimney or ﬂue

serving a separate fuel burning

appliance.

Combusble Material

(must be greater than 50 mm from inner ﬂue)

Flue

Inner ﬂue 100 mm

Outer ﬂue 170 mm

Clearance to combustibles
