annealed austenitic stainless steel.

The pipe seams are continuously seam welded

which provides an excellent gas sealed joint and

offers minimum resistance to flue gas flow.

System 39 is suitable for the following applications :

Flue gas system for gas and oil fired appliances, as

recommended by the appliance manufacturer

For relining existing chimneys using oil and gas

fired appliances

Ventilation—boiler rooms, laundries and kitchens

INTRODUCTION

Mi-Flues System 39 Single Wall Stainless Steel Chimney

APPROVALS

COMPONENTS

Mi-Flues System 39 has been designed to be

installed quickly, safely and simply.

The system comprises of plain lengths, adjustable

lengths, bends, bends with inspection/cleaning

access, tees complete with cleaning inspection caps,

cowls and support brackets.

Mi-Flues System 39 is manufactured and conforms

to :

EN1856-2 T300 N1 D Vm L20040 O(**)

Note : **3 times diameter of the flue

Mi-Flues System 39 is designated suitable for a

connecting flue pipe and rigid chimney liner.

INSTALLATION

1. Select the components required for installation.

2. Ensure the male end of the liner chimney system

always points downwards in the direction of the heating

appliance.

3. Align the locating dimple and twist-lock dimple on

the male end of the chimney liner system with the

locating dimple and receiver on the female end of the

chimney system as shown below.

4.Firmly push both chimney sections together ensuring

to keep locating dimple system in complete alignment .

5. Hold lower chimney section and gently twist

uppermost section to achieve desired twist lock system

Seal using Mi-Flues high temperature sealant (rated

to 1000°C) or a suitable fire cement.

See illustration below

Installation must be in accordance with Building

Regulations Document J.

System 39 operates most efficiently where there is a

vertical run from the appliance to the terminal.

A selection of bends are available to provide an offset

from the vertical. The chimney should not make an

angle more than 45° with the vertical, except where the

flue is connected to the back outlet of the appliance.

To prevent excess condensation of the flue gases and

potential freezing, System 39 is not permitted for

external runs.

Components are joined together by fitting the male

end of the first section into the female end of the

second section (as shown opposite).

Mi-Flues System 39 has a unique press fit jointing

system, which provides structural stability.

This jointing system ensures a quick and easy

installation offering excellent gas tightness

properties.

System 39 has a unique clik clak system which

does not require the use of a locking band.

A cowl is the top rain cap for a chimney. Its purpose is

to stop the infiltration of rain or snow to the inside of the

chimney. For oil fired appliances a stainless steel cowl

is attached to the end of the flue pipe (cowls with bird

guards are not available for oil appliances). For gas

appliances a cowl with mesh should be used.
