Install Guide
A. Design and Installation Considerations
Consideration must be given to:
• Safety
• Convenience
• Trac ow
• Chimney and chimney connector required
It is a good idea to plan your installation on paper, using
exact measurements for clearances and oor protection,
before actually beginning the installation. If you are not
using an existing chimney, place the appliance where there
will be a clear passage for a factory-built listed chimney
through the ceiling and roof.
We recommend that a qualied building inspector and your
insurance company representative review your plans
before and after installation.
If this appliance is in an area where children may be near
it is recommended that you purchase a decorative barrier
to go in front of the appliance.
Remember to always keep
children away while it is operating and do not let anyone
operate this appliance unless they are familiar with these
operating instructions.
Check building codes prior to installation.
• Installation MUST comply with local, regional,
state and national codes and regulations.
• Consult insurance carrier, local building, re
ocials or authorities having jurisdiction about
restrictions, installation inspection, and permits.
CAUTION
NOTICE: JETMASTER ASSUMES NO
RESPONSIBILITY FOR THE IMPROPER
PERFORMANCE OF THE APPLIANCE
SYSTEM CAUSED BY:
• Inadequate draft due to environmental conditions
• Down drafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
• Over drafting caused by excessive chimney heights
• Ideal performance is with height of chimney between
14-16 feet (4.26-4.88m) measured from the base of
the appliance.
C. Negative Pressure
Negative pressure results from the imbalance of air
available for the appliance to operate properly. It can be
strongest in lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water
appliances and other combustion appliances
• Clothes dryers
• Location of return-air vents to furnace or air
conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
- Recessed lighting
- Attic hatch
- Duct leaks
B. Fire Safety
To provide reasonable re safety, the following should be
given serious consideration:
1. Install at least one smoke detector on each oor of
your home to ensure your safety. They should be
located away from the heating appliance and close to
the sleeping areas. Follow the smoke detector
manufacturer’s placement and installation instructions,
and be sure to maintain regularly.
2. A conveniently located Class A re extinguisher to
contend with small res resulting from burning embers.
3. A CO detector should be installed in the room with the
appliance.
4. A practiced evacuation plan, consisting of at least two
escape routes.
5. A plan to deal with a chimney re as follows:
In the event of a chimney re:
a. Evacuate the house immediately
b. Notify re department.
WARNING
Asphyxiation Risk.
• Negative pressure can cause spillage
of combustion fumes, soot and carbon
monoxide.
• Appliance needs to draft properly for
safety.
WARNING
Asphyxiation Risk.
• Do NOT connect this appliance to a
chimney ue servicing another appliance.
• Do NOT connect to any air distribution
duct or system.
May allow ue gases to enter the house.

5. Flue & chimney requirements
Location of the appliance and chimney will aect
performance As shown in Figure xx the chimney should:
• Install through the warm space enclosed by the building
envelope This helps to produce more draft, especially
during lighting and die down of the re
• Penetrate the highest part of the roof This minimizes the
aects of wind turbulence and down drafts
• Consider the appliance location in order to avoid oor and
ceiling attic joists and rafters
• Locate termination cap away from trees, adjacent structures,
uneven roof lines and other obstructions

Existing chimne s should be inspected and cleaned by a qualied
professional prior to installation The chimney must not have cracks,
loose mortar or other signs of deterioration and blockage Jetmaster
recommends a certied professional or a technician, under the
direction of a certied professional
Single skin ue (stainless steel) must be completely enclosed with
single skin brickwork, concrete, or autoclaved aerated concrete
block A chimney plate will be used to weather seal the chimney
Twin skin ues (stainless steel inner, and galvanised outer) can
either be left exposed or enclosed with stud walls and sheet plaster
or timber A minimum of 50mm clearance must be maintained
between the outer ue and any combustibles within the chase or
ceiling cavity (Fig 5.1)
Rivet an inner active starter ue with two female ends to gather to
allow second length to have crimp facing down (Fig 5.2)
The outer ue is then installed outside active ue with crimp facing
up to ensure water penetration on ue above roof runs out
Rivet active ues together at crimped joins
Fix outer non-active ues to active inner ues use 3 x 25mm self-
tapping screws through outer ue at bottom at each join and on top
at each join As an alternative, rivet 4 x 25mm conduit saddles at
each join top and bottom
Ventilate the ues, cut 4 x 25mm notches at bottom of
rst length of outer ue and top of outer ue in either
the ceiling cavity or just below the ceiling When using a

Please read these instructions before beginning
Step by step checklist
1. Check the chimney for cracks, cavities and blockages and
repair these The size of the Jetmaster Firebox is determined
by the minimum dimensions of the chimney ue Minimum
ues areas are:
Model 500, 600, 700sh- 400 cm2
Model 700D, 850-450 cm2
Ensure that this area is maintained throughout the entire
chimney Flues that are 10% smaller than this will work
depending on the height of the chimney Chimney pots that
are too small should be removed Conduct a smoke test prior
to a Jetmaster install to ensure the chimney properly draws
If the chimney does not draw, do not proceed with the
installation Further repairs may be required
2. Measure the width, depth height of the recess The
following table lists the minimum dimensions of the recess
for each unit
• Allow 25mm on each side of the rebox for insulation
A. If recess is too large:
The recess can be reduced by inserting bricks or Hebel at
the sides and/or back, and where necessary between the
top of the unit and the underside of the lintel The
existing hearth can also be built up either with bricks or
by forming a plinth
Use Jetmaster fascias and trims to seals gaps less than
75mm between sides and top of the unit and masonry
B. If recess is too small:
The recess can be made deeper by removing the rollback
and smoke shelf If the height is too low, remove the
lintel and replace at the required height
If the sides have to be removed it is suggested an
experienced builder to do the work as the sides support
inner ues of the chimney
NOTE: Allow 1-5mm expansion gap for all materials
3. Repair any cracks or cavities in the recess especially if it
has been chopped out to accommodate a specied unit size,
and the cavity between a double brick wall has been
exposed
Note: No metal gather or flue is required if the chimney passes a
smoke test.
4. Tape the insulation to back and sides of the Jetmaster
and slide into position, taking care not to snag the breglass
insulation against the sides
Note:
A. Do not recess the unit by more than 110mm.
B. The two smoke outlets on the firebox marry up with the
existing chimney. (There must be a 200mm minimum to any
overhang above smoke outlets).
C. Do not obstruct air intake at the bottom of the unit.
5. Use foil tape and cardboard to temporarily seal outer
edges of the unit to the chimney face then have a test re
using a mixture of dry and damp paper to create a smokey
re
If continuous smoke spillage occurs, check the size of the
chimney pots and the chimney for blockages
“Downdraught” (wind blowing down the chimney) is
recognised by occasional pus of smoke In this case use a
Jetmaster rotating cowl or a high wind cowl
6. Seal unit into position with the masonry, fascias or trims,
ensuring any air leak around frame is limited Allow masonry
work to cure for a minimum of three days
See next page for diagrams.

7. General use
Attaching optional re screen
To attach the firescreen, 1. place either the left or right side hook in between the outer flange and the lowest part of the upper
deflector where it meets the flange. 2. Raise the opposite side to the top corner of the upper corner to locate the alternate hook inside
the flange. 3. Lower into place. For removal, follow the opposite of this instruction.
General usage info
How to use the wood replace
Your Jetmaster fireplace is designed not to spill smoke and by following a few instructions you will achieve optimum heat output,
convenience and fuel economy. Please note that during the first fire the paint goes through a bonding process called curing which
may emit odours. This is normal and it is recommended to open windows to outside to allow the fumes to disappate.
Lighting a re
There are many different ways to successfully light and run a fire all of which require an even balance of the 3 elements of combustion.
Fuel, Heat (ignition source) and Oxygen - if your fire is not operating cleanly it will be due to one of these elements being
compromised. Jetmaster recommends the Home Heating Association website www.homeheat.com.au as a terrific resource for further
information on tips and FAQ’s on solid fuel troubleshooting.
1 Ensure the damper is in the full open position Pull the handle on the left side towards you with the steel handle provided
2 In rebox lay your re lighters 10 to 15 centimetres apart, depending on the size of your rebox Do not use newspaper as a
re lighter On units that are installed with a dual spigot gather, it is recommended to light 2 res directly underneath the two
separate ues
3 Add soft wood kindling in a criss cross pattern above the relighters Softwood kindling allows for re to light quicker and
burn hotter
4 Light re with match or gas lighter Leave for 5-10 minutes maximum and do not leave unattended
5 Load pieces of hardwood that are no wider than a drink can in a criss cross pattern
6 After 30 minutes add the large pieces of hardwood These pieces should be no bigger than a loaf of bread You may attach
your screen now if desired
7 After 45 minutes you can adjust the damper to slightly slow the re down The amount you can close it will depend on the
type of wood used and general weather conditions
If the fire begins to spill smoke, adjust the damper to a more open position. Do not close the damper more than 50% when the fire is in
operation. Once the fire is extinguished, closing the damper will reduce cold drafts and heat loss associated with the open flue.
Always leave a bed of ashes up to the centre crest of the logpan for ease of lighting and to prolong the life of and protect the logpan.
Excess ashes should be removed when necessary, placed in a non-combustible container with a tightly fitting lid and moved outdoors
immediately to a location clear of combustible materials.

AS/NZS 2918 General notes
Fuels
The quality of firewood is extremely important. How long a tree
has been felled or dead for does not indicate how dry the wood
is.
The best way to dry wood is to split it and expose the inner core
allowing the sun to dry the wood naturally.
Good wood merchants will split the wood for you, but may not
season it for you.
The amount of you pay for your wood does not justify how dry
the wood is. The only way to know how dry your wood is, is to
use a moisture meter measuring from the inner core of the
wood.
Only burn wood under 20% moisture. Anything over 20% and
your wood heater will not work efficiently. The energy from the
fire will be used to reduce moisture in your wood and not
produce heat for your house.
Store your wood for at least 12 months after your have
purchased it. Your wood should be at a perfect moisture level, of
around 15 to 20%. Never burn treated wood or painted wood.
Cleaning
The Jetmaster Log Pan is designed to give greater heat and fuel
efficiency. For the duration of the cold season the Log Pan
should never be emptied. The resulting bed of ash and coals
from previous fires will soon become a heat bank generating
more heat than the burning logs. This ash bed also insulates and
greatly extends the life of the Log Pan. This is why an ash bed
must be maintained at all times.
When the level of the ash bed becomes too high, the top layer
can be removed. Depending on frequency of use and quality of
wood, this skimming procedure should not be required more
than once or twice a Season!
To prevent chimney fires as well as enabling the chimney to
draw properly, the chimney/flue should be swept at least once a
season,subject to the quality of timber used in the fire.
General Maintenance
The visible parts of your Jetmaster can be cleaned with a damp
cloth or soft brush. Should you wish you could repaint the unit
with a heat resistant paint?
Safet
The Jetmaster is a safety-tested unit, however, you must never
leave an open fire unguarded. Jetmaster has a screen that is
designed to prevent sparks leaving the fireplace and very
resistant to being accidentally knocked over by young children.
