Installation Instructions
We recommend this appliance be installed by a trained and NZHHA qualified installer.
Warning: the appliance and flue system shall be installed in accordance with AS/NZS 2918 and the appropriate requirements of
relevant building code/codes.
Warning: appliances installed in accordance with this standard shall comply with the requirements of CM1.5 where required by the
regulatory authority, i.e. the appliance shall be identifiable by a compliance plate with the marking “Tested to CM1.5”.
Caution: mixing of appliance or flue system components from different sources or modifying the dimensional specification of com-
ponents may result in hazardous conditions. Where such action is considered, the manufacturer should be consulted in the first in-
stance.
Caution: cracked and broken components e.g. glass panels or ceramic tiles, may render the installation unsafe.
• Maintain a clearance of at least 1 metre between front of the appliance and building structure or any other substantial im-
movable object.
• Your appliance shall be seismically restrained, including the floor protector using the provided holes or brackets. The re-
straints should be sufficient enough to resist a seismic loading equal to 0.4 times the mass of the appliance. We recommend a
minimum of 8mm dynabolts on concrete floors and 8mm coach screws for wooden floors, of appropriate length.
Minimum Flue Height
The top of the flue system should be at least
600mm above the highest point of the roof
ridgeline, if the point of
intersection of the flue system and the roofline is
less than 3 metres from the ridgeline horizontal-
ly.
If the point of intersection of the flue system and
the roofline is greater than 3 metres horizontally,
the top of the flue system shall be at least 1 me-
tre above the point of intersection with the roof-
line. (refer FIG 3)
These are considered to be minimum dimensions, and depending on local conditions, taller flue
system heights may be required for satisfactory performance. The total flue height should be
no less than 4.6m from the level of the hearth.
Flue Installation Detail
Your Ferva appliance should be installed with a HeatSaver Flue System.
A HeatSaver Flue System is available from all authorised Ferva dealers throughout New Zealand.
Use of a flue system other than a genuine HeatSaver Flue System may affect the safety of the installa-
tion, and may affect your warranty.
Insist on a genuine HeatSaver Flue System.

HeatSaver Flue Kit Installation
INSTALLATION INSTRUCTIONS
• This HeatSaver flue system is tested and certified to AS/NZS 2918:2001 Appendix F, which
means it is approved for use on all solid fuel appliances with a flue diameter of 150mm.
• A copy of the Laboratory Test Certificate for this HeatSaver Flue System is included as part of
these Installation Instructions, (refer to paperwork with flue kit).
• Installation of any solid fuel appliance should only be carried out by suitably trained and quali
-fied personnel.
• Position the stove to the desired position, always ensuring that the manufacturer’s minimum
clearances to combustibles are complied with.
• Check that there are no roofline ridges or valleys in the way, or if they cannot be avoided,
that the installer knows how to weatherproof the penetration and reinstate the full strength of
the structure.
• At the ceiling level, construct a square frame of 300mm x 300mm internal dimensions and cut
away the ceiling materials from the inside of this frame.
• Lower the 300mm flue pipe casing into this frame and nail in place when the bottom edge is
25mm below the ceiling level and the 8 nail holes provided are touching the timber frame.
• Check all 4 locating brackets are securely in place and drop 250mm diameter lower casing in
place. This will naturally settle so it protrudes 25mm below the ceiling.
• Make roof penetration, assemble and fit required flue length and install with upper casing.
Secure all joins with at least 3 stainless steel rivets or self tapping screws.
• Frame and brace upper installation as required and flash the roof to shield penetration.
• Fit ceiling plate to ceiling.
• When trimming the stainless steel flue length, ensure the flue is flush with the casing at the
top. If it is higher than the casing, the cowl can not be fitted correctly.
• Fix the bottom section of the HeatSaver Columbia Cowl in place and ensure that it is firmly
down on top of the casing. Then attach top section by bending tab away from the shaft to al-
low the top section to slide down onto the washer. Bend tab back in place once done. Do not
over bend tab so that it touched the shaft. See page 6
• Secure the flue to the fire, drill through flue neck on fire and secure with 2 to 3 s/s screws or
rivets.
• All flue joints should be sealed using a flue cement.
• Ensure a 25mm clearance from the 250mm diameter casing to any combustible material.

Lighting Procedure
Because a downdraft fire operates differently from a traditional fire, it is important to follow these
steps to ensure the fire will operate as intended and to ensure a clean and efficient light up.
What you will need:
• Approximately 16 pieces of kindling wood, about 1kg in weight
• 4 x pieces of small sized wood (intermediate load 1), approximately 300mm in length, 1.2kg
in weight (total)
• 4 x pieces of medium sized wood (intermediate load 2), approximately 300mm in length,
2.5kg in weight (total)
• 2 x fire lighter cubes
• 1 x long handle lighter
Step 1.
Loading the kindling wood
Stack the 16 pieces of kindling wood in a ‘cross stack’ style with the 2 fires lighter placed at the
front of the stack.
Important: Ensure installation instructions have been adhered to before lighting the appliance.
For your comfort, it is advised that you light your first fire with the windows open to allow the es-
cape of paint fumes. This will normally happen for the first 30 minutes of the first burn. Ensure the
fire is run at a high temperature during this period.

13
Lighting Procedure
Step 2.
Light the kindling wood
Light the 2 fire lighter cubes and immediately push the door to a ‘cracked open’ position
Leaving the door in the ‘cracked open’ position, is a very important part of the start up process. In
this position, the door should not be fully closed. It should just be gently push closed until the door
latch just rests against the firebox, without engaging the door handle, leaving an opening between
the door and the firebox.
If the door is fully shut, the fire will go out because the fire is not up to operating temperature. This
is because the door handle opens and closes the ‘bypass damper’ which changes the operation of
the fire from updraft to downdraft. Downdraft can only be sustained when the fire is up to temper-
ature.
5 to 10 mins
Step 3.
Place ‘Intermediate load 1’ into the fire
After approximately 5 to 10 minutes (or when the kindling wood has fully ignited), place the 4 piec-
es of small wood (intermediate load 1) into the fire and return the door to the cracked open posi-
tion.

14
Lighting Procedure
5 mins
Step 4.
Place ‘Intermediate load 2’ into the fire
After approximately 5 minutes, place the 4 pieces of medium wood (intermediate load 2) into the
fire and return the door to the cracked open position.
6 mins
Step 5.
Close the door
After approximately 6 minutes, the fire is now at a temperature where the fire can be switched into
downdraft mode. Simply raise the door handle to 90 degree position, push the door fully against
the firebox, and push the door handle downwards so that it tightly engages the catch. In the fully
closed position the fire will operate in downdraft mode.
Cracked Open Position Fully Closed

15
Normal Operation
Once you have completed the start-up procedure, your fire is ready to resume its normal
operation.
The fire is designed to take 2 pieces of wood approximately 300mm long and about 1.5kg each
(total load of 3kg).
Your appliance should be reloaded when the previous load has burned down to red embers.
The Ferva Saturn is design to be reloaded in a similar way to traditional fires, simply open the door,
place the logs in an appropriate position and close the door.
The action of the door handle will release the by pass damper when opened and close it when the
door is fully closed, so no additional operation is required for this feature.
Once the logs are in place and the door is shut, you are free to adjust the main air control to run
the fire on either a high or low setting.
Important: firewood should be loaded in a sideways direction when operating this appliance.
The door must be closed at all times during the operation, except during the light up
procedure, refuelling and occasional poking of the fire when necessary. Ensure door
seals are maintained in good condition.

Cleaning and Maintenance
Step 1.
Remove Crucible Cap
Step 2.
Using an appropriate tool, scrape ashes
down the centre hole
Step 3.
Open bottom door and remove ash tray
and safely dispose of ashes
Step 4.
Return the fire to its normal configuration
Disposal of Ashes
Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes
should be placed on a non-combustible floor or on the ground well away from all combustible mate-
rials, pending final disposal once cooled.
Removal of Ashes from fire

Consumables
Some parts of your Ferva fire are considered consumable. They are designed to be re-
placed as they will degrade over time. The life of the consumables will vary depending
on;
• Frequency of use. How often the fire is used
• Rate of burn. Is the fire burning on low or high the majority of time
• Type of fuel. Some woods are much harsher than others.
• Level of ash.
General items that are considered consumables:
• Baffles
• Fire bricks
• Crucible parts
• Glass seals and door ropes
It is very important that you replace these parts when they show sign of wear. They ef-
fect how the fire runs and you may increase your fuel consumption or lower your effi-
ciency if not replaced, and can in some cases, damage the firebox. It is generally obvi-
ous once a part is in need of replacement. Steel components may split or large holes
may appear and fire bricks may disintegrate. Fire bricks that are cracked but still remain
in place are completely safe to use and only need to be replaced when they no longer
remain in place. A cracked fire brick may still last years of use.
We recommend you check your fire visually several times a year for damaged compo-
nents.
Caring for your Fire
Cleaning your Glass
Wiping your glass regularly with a damp cloth when cold will keep the glass clean. If a
thick build up of creosote builds up, oven cleaner works well to remove it.
Cleaning the Outside of the Fire
Ferva fires are finished in a high temperature paint. Only use a damp cloth (no chemi-
cals) when cleaning the outside of the fire. If any scratches occur, you can easily touch
up the fire with an aerosol can of matching paint. This is available from your retailer or
Harris Home Fires.
Cleaning the Flue
Keeping your flue clean is important. We recommend that you have your chimney swept
at least once a year. A blocked flue not only effects the performance of the fire, but can
also be a hazard as you are susceptible to chimney fires.
Ash Level
Do not let the level get too high as you run the risk of logs and coals falling out of the
fire. You also get less wood in the firebox.

Creosote Formation
A small intense fire is preferable to a large smouldering one, to reduce the amount of
creosote. When wood is burned slowly it produces tar and other organic vapours, which
combine with expelled vapour to form creosote. These creosote vapours condense in the
relatively cool flue of a slow burning fire. As a result, creosote residue accumulates on
the flue. When ignited, this creosote makes an extremely hot fire.
The flue should be checked at least every 2 months, during the burning season, to
determine if a creosote build up has occurred. If this is the case, it should be removed
by a chimney sweep to reduce the risk of an unexpected flue fire.
Your appliance has been designed to produce low levels of creosote at high and low
settings.
In the event of a chimney fire, close the firebox door, fully close the heat
control, vacate the premises and call the fire service.
Storage of Fuel
Do not store fuel within installation clearances or within the space required for refuelling
or ash removal.
Wood should always be stored in a dry place out of the rain. We recommend your wood
be seasoned for at least 3 months before use. Dry wood also burns hotter and more ef-
ficient than wet wood.
The fuel approved for use in Clean Air Zones in this appliance is wood with a moisture
content of less than 25% of dry weight. This usually means green timber left for at least
three months to air dry.
