Installing the Straxgas Turboflue
The Strax Turboflue is an Electro-mechanical Automatic Flue System designed
for the safe removal of flue gases from the Straxgas range of decorative coal ef-
fect fires. It consists of a 240V A.C. 50Hz electrically operated fan unit fixed on the
external wall, a horizontal duct with 38mm insulation situated within the wall, and a
gather for the appliance, fixed to the appliance in such a way that the flue be-
comes an integral part of the appliance, It comes complete with pre-wired
A Strax Turboflue enables you to fit any of the attractive Straxgas fires (see sep-
arate leaflet) in any room without a chimney provided there is a suitable external
wall at ground floor level. i is ideal for single storey extensions.
Subject to site conditions, with the Strax Turboflue the Straxgas appliance may be
installed either to a straight wall, or in a corner.
The installation of a Strax Turboflue offers the additional benefit of controllable ,
mechanical room ventilation, independent of the gas fire.

Description of The component parts and the fail-safe system have been made to a high specifi-
components cation. All components are factory fitted and tested:
The Gather is manufactured in 3mm mild steel plate, slactrically welded and sup-
plied in a heat resistant, satin black paint. It is fitted on top of the Straxgas fire. The
seal supplied should be applied under the flat flanges of the gather prior to screw-
ing in the four self-tapping screws to provide an airtight seal. This makes the
gather an integral part of the appliance. The gather is supplied with a horizontal
spigot as standard. (An alternative gather is available with a vertical spigot to be
used with a 90° band). The horizontal gather has a male spigot which locates into
a 1mm thick, grade 316 S/S female spigot on the wall duct.
The Wall Duct consists of two parts:
1. The outer casing is made of 1mm galvanised steel formed into a square box
231mm square with a 3mm mating flange for the fan housing unit, the rear
face of the flange being fitted against the outside wall, The flange has four
tapped bolt locations for the fan housing unit and also two countersunk holes
to secure the wall duct to the outside wall if desired. To secure the duct to the
internal wall, the duct is supplied with a metal tag which may be bent at right
angles and secured with a screw.
2. The silencer is located inside the outer casing and locates on a male spigot in
the rear of the casing. It consists of a preformed section of glass fibre
insulation of a density of 90-110 kgs/m?®, a thickness of 38mm, and is able to
operate continuously at a temperature of 230°C. The part number is T305.

The Fan Housing is manufactured from 3mm mild steel plate, surface treated by
primer and supplied in a grey hammer finish. It consists of:
1. A male spigot which locates into the silencer.
2. A silencer sealing flange.
3. A wall duct mounting flange which is secured to the outer flange of the wall
duct by using 4 x 6mm bolts; a rubber gasket is trapped between the mating
The Motor Housing consists of:
1. A motor, 50W 240V A.C. 50Hz, 1400 RPM, fitted with a multi-blade impeller.
2. Amotor plate 3mm thick bolted to the fan housing.
3. Aspun aluminium cover dome.
The control system is designed to provide a fail-safe operation, automaticalty
closing down the gas supply to the fire via. the solenoid valve in the control box in
the event of:
« Fanfailure
« Mains power failure
e Inadequate flue gas extraction
Should any of these events occur, the system may only be restarted via. the red
manual reset button on the control box. (See Figure 3 for the wiring diagram.)
The location of the control box must be between the fire and the isolation cock; in
the false chimney breast for instance.
The Straxgas fire, Turboflue and control system should ideally be installed and
tested before any false chimney breast is completed.

Conditions of
Installing the Straxgas Turboflue
The Strax Turboflue should only be installed with a compatible Straxgas appliance
(for which separate installation instructions apply). The Turboflue may be installed
on any suitable external wall of a thickness, including plastering, ranging from 225
— 350mm (9" - 14").
The fan housing with its motor unit must be located on an external wall not
above ground floor level.
it must be installed in such a way that it does not discharge iro any buildings. it
must be at least 600mm (24") from any openings in the wall (windows, doors or
similar). Due consideration must be given to environmental conditions. Sound
assessment of the location of the Turboflue is essential to prevent nuisance shut-
down due to adverse gale force wind conditions. if the flue terminal is less than 2
metres above the ground a terminal guard must be fitted. (Straxgas are able to
supply a suitable guard, part no. 7140).
The construction of the fireplace, its surround and the false chimney breast should
be made from non-combustible materials and in accordance with current Building
Regulations, Codes of Practice and local by-laws. According to B55871,Part
2.1991 the hearth should be constructed of such a material that the heat trans—
mitted through it shall not give rise to a temperature greater than 65°C {150°F) on
its underside. See also approved document J1/2/3 "Heat Producing Appliances”
issued by the Department of the Environment, 1985.
It is essential to provide sufficient alr into the room; see the note on page 2
about a fresh air inlet.
The Straxgas appliance may be installed up to 4.5M (14.5ft) from the ventilation
unit. Additional lengths of cables will then be required and should be ordered with
the Strax Turboflue. Extension pipes of $/S, and elbows at 45° and 90° are also
available. For corner installations you may require a Right or Left Hand connection
between the gather and the wall duct. You should connect a 90° bend to a gather
with vertical spigot part no. T405.
Packed in one box are: Ventilation unit (made up of the fan and motor housings),
Wall Duct, Control Box with cables and P-clips, Self-tapping screws for the
Gather. The gather will be packed in a separate carton.
lt is the law that all gas appliances are installed and serviced Бу а сотре!ет! рег-
son in accordance with the Gas Safety Regulations (Installation and Use), 1990.
Failure to install the appliance correctly could lead to prosecution.
The installation must also be in accordance with these Installation Instructions,
and all the relevant parts of the Local and National Building Regulations where
The Strax Turbofiue should only be installed with a compatible Straxgas ap-
pliance, for which separate installation instructions apply. Have these to hand as
reference to them will be made,
The Strax Turboflue enables you to fit the fire to conventional walls of 8°, 11", Or
14" thickness. To establish the depth of the false chimney breast, use dimension
'E' in the product leaflet plus 1" (25mm) for the insulation slab if supplied with the
appliance. Comer installations can be accommodated at a distance up to 4.5M
(14.5ft) from the Strax Turboflue.
The Straxgas appliance can have the gas supply entering from the left or right
hand sides, or from the rear,

Installing the Straxgas Turboflue
Proceed as follows:
1. Make certain that a hearth of sound non-combustibie material is provided
beneath the Strax fire to satisfy requirements of BS5871,Part 2,1991 (see
para. A4 — Site conditions, also the installation instructions for the appliance
paras. 1A and 2A).
2. Measure from the top of the hearth and draw on the wall a horizontal line ata
distance from the hearth as shown in the Straxgas fire installation
instructions {outline drawing). This marks the top edge of the cutout in the
3. Draw a vertical line on the wall on the centre line of the fire, mark out on the
wall a 240x240mm (9.1/2in.x9.1/2in.) square equally each side of the vertical
ine and down from the horizontal line. Double check and cut out the
brickwork of the internal wall, and open up through the external wall face.
WARNING: If the cut-out is being made at a low level care must be taken to
avoid breaking through the damp course.
Note: The silencer of the wall duct is made of preformed glass fibre with a thick-
ness of 38mm (1.1/2"). The requirements are that flue pipes shall be at least
25mm from any combustible matenal, or, where passing through a wall, floor, or
roof, that they be separated from any combustible material by a non-combustible
sleeve enclosing an air space of at least 25mm around the flue pipe. For a
double-walled flue, the 25mm distance should be measured from the outside of
the inner pipe.
The thickness of 38mm of insulation material in the silencer more than meets
these requirements and has to be borne in mind when considering:
* Cavity wall insulation. Chack the nature of the insulation material used.
+ Dry lining on wooden battens. Check the distances.
4, Carry the complete unit outside and pass the control box and its flexible
conduit through the hole in the wall. Slide the wall box/fan unit into position
with the discharge outlet facing down.
5. Place the Strax fire on the hearth, position the gather on top, and check for
spigot alignment to the wall duct. Make any necessary adjustmenis as
6. The spigot of the gather is the male connection to the spigot of the wall duct.
Whilst the Strax Turboflue may be installed through a wall of a minimum
thickness of 225mm (9%), the wall duct itself is 300mm {12") deep which
together with the spigot adjustment will allow a maximum distance from the
gather to the axternal wall face of 350mm (14°. However, extension pieces
made in 1mm thick stainless steel are available in standard lengths of 12"
and 18".
Determine the correct distance between the Straxgas fire and the inside wall,
and position it according to its installation instructions.
7. Make good surrounding brickwork on both the internal and the external wall
faces. If needed, the flange of the wall duct may be secured to the external
wall by means of two countersunk screws. To gain access to the holes in the
flange unbolt the fan housing from the wall duct. Apply a sealing mastic (not
provided) to the rear of the wall duct flange before screwing it to the wall,
Inside the room, bend the fixing tag up against the wall and secure with the
screw and rawlplug provided.
8. Drill the top plate of the fire and secure the gather using the self-tapping
screws provided, Make a positive seal using the compound supplied.
9. The control box should ideally be installed prior to the building of the false
chimney breast, The control box can be fitted on either side of the fire at
skirting level.
