6. Chimney
The fireplace must be flued with the
recommended size flue (see
specifications in front of this book on
page 2) to the outside atmosphere not
less than 4,6 metres high, and must be
cowled.The flue must be swept with a
brush before installation, and annually
thereafter. DO NOT attach the gas fire
to a flue pipe of less than 200 mm
internal dimension.
5. Ventilation
Two ventilators to the outside must be
provided, one at just below ceiling level
and one at floor level. The existing
regulation states that : an air supply
must be provided up to 150 cm2 for
50 MJ input.This must be provided in
the form of two ventilators, one at
ceiling height and one at floor level.
Most properties have a ventilator at
ceiling height.The lower vent can be
made quickly and cleanly using a core
drill and fitting a sleeve and grids at
each end and is best placed on the
same wall as the fireplace, and close to
the sides of the fire.
NB: Larger vents are required if venting
to well ventilated adjacent room (300
cm2).

and minimise heat loss to the building.
8 Where offset in the flue is required,
do not bend more than 45 degrees.
Jetmaster fabricated bends are available.
8. Fitting the Jetmaster
Convector Box
(This work can be carried out by a person
who is not registered LPGAS Association
installer.)
1 Slide the convector box into the recess.
Ensure that no insulation or other
material can fall and obstruct the fume
outlets. Ensure that a seal is formed
behind the frame of the convector box
such that the only air which can reach
the flue must travel in through the
front of the convector box and up
through the fume outlets.
2 Check that the flue outlets on top of
the convector box will not be
obstructed.Where the convector box
is to be installed beneath a particularly
deep lintel supporting the chimney
breast and the flue outlets might be
partially obscured, steps must be taken
to chamfer the underside of the lintel
to 45 degrees to provide a smooth,
unrestricted path for gases.
3 Check that the convection inlet channel
at the base of the front of the
convector box is not restricted.
4 If a gather has not been fitted, for
instance when the convector box has
been installed in an existing fireplace
opening, mark and drill two securing
holes in the base of the convector box
and the hearth below, and secure the
convector box to prevent it from
moving forward.
7. Preparatory Building Work
(This can be carried out by a person who is
not a registered LPGAS Association installer.)
1 When building the Jetmaster Gas
Convector into an existing fireplace,
first remove all loose materials from
the recess and measure the opening
and recess to ensure that the Jetmaster
Gas Convector will fit.
2 The recess must be large enough to
provide a clearance of 15 to 20 mm
around the sides of the convector box
and be in accordance with the
dimensions given on page 2. Cut away
or build up to achieve the desired
dimensions.
3 Where the recess is to be newly built,
form the recess to give a clearance
around the sides and back of the
convector box of 15 to 20 mm to
accommodate the fibreglass insulation.
4 Where the sides or back of the recess
have to be built up, and the masonry
flue gather of the chimney is to be
used, build up to the height of the
convector box only and then top with
a sloping fillet or mortar.
5 If a metal flue gather with flue liners
is to be used, they are available from
Jetmaster or any authorised Jetmaster
dealer.
6 Check that the hearth, or new plinth
where this is constructed, is level.
7 Wrap the faces and sides of the fire
with insulating material.This insulation
is not essential but it is recommended,
particularly when fitting to and outside
wall, since it will maximise heat
retention in the convection chamber,

9. Gas Cylinder, Pipe Runs and
Sizes
(This work must only be carried out by a
person who is a registered LPGAS Association
installer.)
1 Jetmaster LP Gas Convectors must
be operated off one or more 48 kg
cylinders, depending on size of unit.
The cylinder(s) must be positioned
outside, as close as possible to the
appliance, and in any case not further
than 30 metres, the cylinders must be
away from heat sources, electrical
devices, drains, windows and
combustible materials, in accordance
with SABS 087 Part 1: March 1999.
Cylinders must always stand in the
VERTICAL position and must be fixed
so they cannot fall or be knocked
over. For best performance, avoid cold
areas and shade.Where the regulator
or pipework is in a position which is
liable to be very cold in winter, it is
advisable to lag them to prevent
freezing up. It is always advisable to
fix the regulator vertically rather than
horizontally. This will prevent any
condensation settling in the bottom
of the regulator which will freeze up
in the cold weather causing the Gas
Convector to shut down.
2 Check the Jetmaster Pipe Sizing Chart
below to choose the correct size of
pipe for the Gas Convector size and
length of run. Although Jetmaster
supplies 4 metres of 8 mm copper
tube with LP Gas Convectors, it is
not necessarily of sufficient size if
larger fire or longer than 4 metre run
are to be fitted. Be sure to fit the right
size pipe. Do not run more than one
gas fire off each supply, without first
checking the fitter’s supply chart.Any
queries please contact Jetmaster
Technical Department.
LP pipe size: From cylinder and
low pressure regulator (28
Mbar) to gas appliance:
Copper tubing 8mm 15mm
LP Gas up to to 30 m
Convector 4 m
It is recommended by the LPGAS
Association that any pipe run greater
than 9 metres is supplied under high
pressure and a low pressure regulator
is fitted within 4 metres of the fire.
3 Having positioned the 48 kg gas
cylinder in a fixed position, connect
the regulator supplied to the flexible
hose, and the male hose connector
to the end of the copper tubing using
the compression fitting.These fittings
are supplied and should be used. If a
larger pipe is to be used then the
correct size of fittings will have to
be obtained.
4 Tighten the hose clamps and connect
the regulator to the cylinder. The
regulator should be protected from
rain and fixed in the vertical position
if possible alternatively angle the
regulator so that liquids cannot collect
on the top causing rusting of internal
components and subsequent
malfunctioning, i.e. the plastic cap
should not face upwards.The air vent
in the regulator must be pointing
downwards.
5 Cover the end of the gas pipe to
prevent dirt getting into it and
damaging the valve, which will
invalidate the Warranty.

6 If the pipe is to be laid in concrete,
or comes through a wall or chased
into a wall then the pipework must
be sleeved.This sleeve can be electrical
conduct or plastic pipe of a size larger
than the outside diameter of the gas
supply line. Place the gas pipe within
the sleeve for protection.
7 Run the gas pipe from the cylinder
to the area of the fireplace allowing
a full metre of free pipe at the fireplace
end; pipe may be brought in through
either side or the rear of the gas fire.
8 All bends should be made with a pipe
bender to prevent a restrictive kink
forming.
10. Fitting the Gas Burner
(To ensure that the burner and coals are
not damaged, this work must be done after
all building work has been completed. This
work can only be carried out by a person
who is a registered LPGAS Association
installer.)
1 Drill the side or the back of the
Jetmaster with a 10 or 12 mm drill
for the gas pipe entry point. Sleeve
the gas pipe with metal/plastic tubing
where it is to pass through the wall
of the convector box to protect it. If
the pipe run from the gas cylinder
has been made with larger than 8 mm
pipe, reduce it as close as possible to
the fire but not more than 4 metres
away, by using a reduction fitting. Now
that the pipe work is within the
convector box, secure the convector
box by screwing it to the floor. (See
7.4 above)
2 Purge the pipe for dust and debris by
running the gas for a few moments;
failure to clear the dust or debris
from the pipe will invalidate the
Warranty.
3 Remove the burner from its packing
and examine the connections,
checking that none are loose.
4 With the burner immediately in front
of the convector box, place the unit
in the frame supplied, run the gas pipe
to the test point nipple, which for the
LP burner is positioned on the right-
hand side of the control valve when
viewed from the front. Place the
burner and frame in the convector
box and connect the pipe with the 8
mm compression nut and olive making
sure that the connection is gas tight.
Do not strip it. Use of PTFE tape will
invalidate theWarranty as small pieces
can enter the pipe and damage the
valve.

5 Having placed the burner tray in the
frame supplied, push to the back of
the convector box, making sure that
there is enough space between the
front edge of the burner tray and gas
front to allow the ceramics to sit in
the correct position.Adjustment on
the support legs on the burner may
be required.
6 Open the gas supply and test for leaks
as far as the valve, attaching a
manometer or U gauge to the test
nipple, making sure that the little screw
on the test nipple is screwed tightly
back in place when testing has finished.
The dynamic pressure should read 28
MBar. If the pressure is lower, check
the regulator on the cylinder and test
all joints on the pipe-work and burner
with an electronic gas leak detector
or leak test fluid. Rectify and test again.
7 Fit the gas front.

CARE SHOULD BE TAKEN WHEN HANDLING THE CERAMICS When assembling the ceramics on the Deluxe Burner it is important to make sure that pieces of ceramic are fitted properly. The 2 pieces of ceramic that go onto the front ceramic support tray should be behind the stop lugs, not on top or pushed down onto the lugs. If these ceramics do not fit then a fine file should be used across the whole of the front edge of the ceramic pieces until enough has been filed away so that they lay flat on the base of the front ceramic support tray and behind the stop lugs. The same process should take place with the two side cheeks. If they do not fit then the outside edge of both ceramic side cheeks should be filed down until they fit correctly.

12. Commissioning the Fire
Connect a suitable pressure gauge to
the pressure test point. Light the fire
on maximum as described in the “User’s
Instructions”. Check that the setting
pressure is in accordance with that
given on the Chart in the “Technical
Data” Section or on the Data Label
found in the appliance. Adjust the
Natural Gas or Propane Regulator as
necessary.After this has been checked
shut down the gas fire.
Temporarily isolate the fire from the
mains supply. Then disconnect the
pressure gauge, replace the pressure
test point sealing screw, reinstate the
mains supply and test for gas soundness.
Turn the control knob and light the
pilot as described in the “User
Instructions”.Turn the control knob to
the maximum position and fit the ash
pan cover. Check that after ten minutes
all the products of combustion are
entering the flue by traversing the
perimeter of the fireplace opening or
canopy by using a smoke generator e.g.
smoke match.
Once the fire is installed and
opperational the installer must check
for spillage. Carry out the lighting
procedure and turn the fire to high.
Allow to warm up for 5 minutes and
then using a smoke match or joss stick
set 25mm down and 25mm inside of the
fire opening run the match across the
width of the opening to check that all
of the smoke is drawn away. Some small
whiffs of smoke may be expelled from
the extreme ends of the fire opening
and this is quite normal.
Repeat the test with doors and windows
to the premises open and closed, and
with any extractor fans in the same room
or adjacent rooms running on high.The
fire should continue to clear its
combustion products.Also operate any
other flued appliances in the same or
neighbouring rooms and ensure they
continue to function satisfactorily as
multiple flues can work against one
another.
If spillage is detected during this
procedure it could indicate a faulty flue
or lack of ventilation. If the problem
cannot be rectified immediately,
disconnect the appliance, and advise the
customer not to use the appliance until
the problem has been resolved.
The customer should always be advised
of the need for regular servicing and
checks to ensure the continued clearance
of combustion products.

User’s Instructions
13. General
This fire is intended for decorative
purposes. Any purpose provided
ventilation should be checked regularly
to ensure that it is free from obstruction.
This fire should be serviced regularly by
a qualified person.
It is recommended that a guard be used
for the protection of young children, the
elderly or infirm.A vacuum cleaner may
be used to clean the appliance.
DO NOT throw rubbish etc. upon the
coals or otherwise disturb the fuel bed.
Debris from any source or soot formed
should be removed from time to time.
See “Cleaning Instructions”.
The pilot light and flame sensing device
fitted to this fire is also an atmospheric
sensing device which shuts off both the
main burner and pilot if evacuation of the
combustion products is interrupted. If
the fire shuts itself off, do not
use the fire and have the flue and
fire checked by a qualified person.
Due to the newness of materials the fire
may give off a slight smell for a period of
time after commissioning.This is quite
normal and any odour should disperse
after a few hours operation.
Warning Notes
Properly installed and operated this
appliance will not leak gases. Persistent
fume emission must not be tolerated. If
fume emission does exist, then the
following steps should be taken:
1 Open doors and windows to ventilate
room.
2 Turn the fire off.
3 Check for flue blockage and clear if
necessary.
4 Do not attempt to re-light the gas
grate until the cause of the emission
has been identified and rectified.Should
assistance or advice be required
contact your nearest agent.

14. Lighting the Fire: 550 & 700
Gas Convector
The positions of the control valve are
depicted on the control panel fitted
around the control knob.
If the main burner or pilot light are
extinguished for any reason do not
attempt to re-light the pilot within three
minutes.
The off position is self explanatory -
preventing any gas from passing through
the control valve to either the pilot burner
or to the main burner.
By pressing the control knob in it is
possible to turn it anti-clockwise.The first
function is to turn on the gas to the pilot,
this occurs just before reaching the pilot
position. (If the fire has not been lit for
some time it may be necessary to hold
the knob in this position for some seconds
to clear the air from the pipe and allow
gas to reach the pilot burner). Once gas
is available at the pilot, continual rotation
anti-clockwise will cause the piezo ignitor
to spark.This is accompanied by a click
at the valve, and should result in the pilot
burner igniting.This should be verified by
looking at the left-hand side of the fire
tray, behind the front coal piece.
Once the pilot is lit the control knob
should continue to be pressed in for 10
- 20 seconds. In this time the pilot flame
will have heated the flame supervision
thermocouple sufficiently to operate a
hold on magnet within the valve.The knob
should then be turned so that the pointer
is approximately horizontal.This allows
gas at a low rate to enter the burner and
be ignited by the pilot flame. Once the
fire has fully cross lit, allow approximately
15 seconds at this setting to allow the
flame to fully establish before setting to
any level between Maximum and Minimum
by adjusting the control knob accordingly.
To turn off the main burner, turn the
control to MIN - press the knob gently
until it will turn clockwise to the pilot
position.To turn off the pilot press knob
and turn to off.
If burnback occurs underneath the
burner, turn knob to the off position.
Then re-light the fire. If this problem re-
occurs switch off unit and call your gas
installer.
Thus the sequence is:
A. To Light the Fire
1 From off press the control knob in
and turn slowly anti-clockwise.
2 When the ignition click occurs,
check that the pilot is lit (if not
repeat 1 & 2).
3 Hold knob in for 10 - 20 seconds.
4 Release knob and check pilot
remains alight.
5 Turn knob until pointer is horizontal.
The fire should then ignite.
6 Let fire fully cross ignite and allow
approximately 15 seconds.
7 Adjust flames to required level
without pressing knob.
B. To Extinguish the Fire
1 Turn control knob clockwise to
minimum position.
2 Press knob gently until able to
continue turning clockwise to pilot.
3 To extinguish the pilot, press knob
and turn to off, although it is in order
to leave the pilot permanently lit.

and turn anti-clockwise until the
PILOT POSITION
(Fig. 2B) is opposite the indicating
arrow.
4 Push the control knob fully in, and
with it held in position, fully depress
and push the end button on the piezo
spark ignitor and the pilot should light.
If the pilot has not lit, repeat the
operation.
5 Once the pilot is lit, continue and hold
in the gas control knob for a further
10 -15 seconds to establish the pilot.
If the pilot fails to remain alight repeat
the procedure, but hold the gas
control knob in for longer to allow
the pilot to establish.
C. To Light the Fire
1 If the pilot is not already alight, light
the pilot as described in B.
2 Slightly depress the gas control knob
and turn anti-clockwise until the
MINIMUM FLAME POSITION (Fig.
2C) is opposite the indicating arrow.
The burner will then ignite.
3 Turn the control knob to MAXIMUM
FLAME POSITION (Fig. 2D).
4 Check setting pressure on the inlet
pressure test point at the maximum
rate (LPG 2.75 kPa).
5 Depress and turn the gas control
knob clockwise until the PILOT
POSITION (Fig. 2B) is opposite the
indicating arrow.The fire will go out
and the pilot will remain lit. Remove
the gauge from the pressure test point
and refit the pressure test point sealing
screw.
6 Turn the fire on and check for gas
soundness.
7 Refit the air inlet grill.
D. To Turn the Fire Off
1 Remove the air inlet grill.
2 Turn the gas control knob clockwise
to the MINIMUM GAS RATE (Fig,

16. Cleaning Instructions
NOTE: Due to the ceramic fibre material
used in the fuel bed it is inevitable that
cleaning/replacement can be a dirty and
dusty operation. Suitable precautions should
be taken. Due to the intense temperatures
reached in the fire some surface cracks may
appear on the ceramic components.This is
quite normal and will not affect the safe
operation of the appliance.
1 Turn off the fire and allow it to go
cold.
2Carefully remove all the coals one
at a time by hand and remove any soot
deposits with a soft brush.
3 Remove any debris etc., from the back
board.A vacuum cleaner may be used
with care.
4 Carefully reposition or renew the
coals as described in “Positioning the
coals”.
5 Do not add any additional logs or
coals.

17. General
The following servicing procedure
should be carried out regularly and
only by a qualified person.
NOTE: Due to the materials used in
the fuel bed, it is inevitable that
servicing can be a dirty and dusty
operation. Suitable precautions should
be taken.
Important:The pilot and flue sensing
device fitted to this fire is also an
atmospheric sensing device. If for any
reason any part of the pilot assembly
is to be replaced the entire assembly
including the pilot burner,
thermocouple electrode and injector
must be exchanged complete for a
pilot assembly from the original
manufacturer only.This atmosphere
sensing device is not adjustable and
must not be put out of action.
18. Servicing Procedure
1 Turn off fire and allow it to go cold.
2 Turn off gas supply at the isolation
tap.
3 Carefully remove all the coals and
ceramics one at a time by hand and
remove any soot deposits by hand
with a soft brush i.e. paint brush.
NOTE: Due to the intense
temperatures reached in the fire
some surface cracks may appear
on the ceramic components.This
is quite normal and will not affect
the safe operation of the appliance.
4 Disconnect the gas pipe from the
valve and lift the gas grate out of
the fire box.
5 Remove the injectors then clean
and visually inspect for damage
before replacing.
6 Clean the burner tray and flame
strip.
7 Visually inspect the gas grate for
any defects before replacing.
8 Re-assemble in reverse order,
reconnect to gas supply and check
for gas soundness.
9 Replace all ceramics and coals as
described in “Positioning the Coals”.
10 Check that any purpose provided
ventilation is free from obstruction.
11 Re-commission the fire as described
in “Commissioning the Fire”.
