DOOR HANDLE AND DOOR
The door handle is pre-fitted and should not
require any adjustment on assembly of the fire.
Any adjustment required to maintain the correct
fit of the door is made at the door catch pin on
the right side of the door lip. To adjust the fit of
the door catch, loosen the lock nut and turn the
catch pin to loosen or tighten the fit. Re-tighten
the lock nut. Refer Fig 3.
TOPOGRAPHY OF THE LAND
The slope and position of the land in relation to the home has a bearing on how the wind
will interact with the fire and flue system. Care needs to be taken to ensure that the flue
termination is in the correct position to maximise performance.

Before the wood fire is used, ensure that a Compliance Certificate (supplied by
a Registered Installer and/or Territorial Authority Inspector) is obtained for the
user. We encourage initial demonstrations on how to light and operate the fire to
ensure the user can confidently operate the fire for safe and efficient performance.
Determine the total length of flue pipe and outer casing required by measurement.
Prepare chimney for accepting flue, and fixing of outer casing to chimney crest.
Install the selected Kent wood burner into the prepared fireplace. Once in position and
level fix the fire to the base of the fireplace enclosure with suitable anchors through the
supplied fixing points in the base of the wood burners outer box.
Assemble the flue pipe lengths with the swaged ends of the upper sections inside the
plain ends of the lower pieces. This may be done on the ground and then the whole
length lowered into the chimney, or assembled length by length from the top of the
chimney. Note: Drill and fix each length with three stainless rivets or self-tapping screws.
It is important that each flue pipe joint is sealed with commercially available flue sealing
compound, including the joint between the flue spigot and the first length of flue pipe.
Locate the flue or adjustable bend into the flue outlet of the heater.
Ensure the top of the casing terminates at a point complying with the general guidelines
noted previously and that the flue pipe extends above the chimney casing by 180mm.
Secure the top spacer bracket to the flue pipe and ensure the slots fit snugly inside the
chimney liner.
Secure outer liner to top of chimney and cement into position with mortar or other suitable
sealing compound ensuring that there are no gaps and a water tight seal is achieved.
Slide the flashing cone over the top of the flue pipe, until it rests firmly over the top spacer.
Secure with stainless rivets or screws.
Fit the cowl to the top of the chimney liner. Do not secure this, as it must be removable
for servicing the flue.

WIND CONDITIONS
Care needs to be taken to ensure that the flue termination is in the correct position as
wind and gusts hitting the flue and cowl system may cause back draft down the flue and
into the home.
PRESSURE DIFFERENTIAL, VENTING AND EXTERNAL AIR INTO THE
BUILDING
All fires need air to burn and draw correctly. Kitchen fans, air conditioning units, high
wind zones and naturally forming draft spaces can all have an effect on the pressure
difference inside the building to the outside. A lower pressure in the building may induce
a draft down the flue system and back into the building causing the fire to smoke or spill
into the building. Care needs to be taken at the design and installation stage to ensure
adequate ventilation of the building to ensure that there is always a neutral or positive
pressure at the fireplace and a negative pressure at the flue outlet. This will ensure that
the draft in the flue system is always to the outside.

FLUE:
The Inbuilt box is supplied with a Flue Transition Kit of 600mm long flue components. These
components are specially ventilated and must be used at the bottom of the flue system.
The 150mm stainless steel flue fits into the standard flue spigot of the fire. The 200mm
casing sits down onto the top of the firebox casing, with the venting holes at the bottom.
The 250mm casing fits into the socket of the Inbuilt box with the venting holes at the
bottom. No substitutions may be made for these components.
Additional extension kits of 150mm, 200mm, and 250mm flue must be purchased to suit
the particular installation. At least three flue extension lengths will be required to meet the
minimum height requirements of 4.6m above the floor protector. Refer to the Logfire II or
Rata instructions for general flue requirements.
The Flue extensions are installed in the usual way on top of the Flue Transition Kit.

For all practical purposes, the air control should be fully open when there is unburnt wood
in the wood fire. Fire holding periods may be increased by turning down the air control,
this is at the cost of greater emissions and creosote production. At low settings, creosote
may condense on the glass, reducing the visibility of the fire. The best indication that
the fire is operating correctly is that the glass remains clean, without build-up of black
or brown deposits. Some whitish bloom on the glass is normal and does not generally
indicate a fault in operation.
The way you burn your wood fire will also determine what is happening up the flue.
Continued burning at high rates with a good clean flame will minimise soot and creosote
deposits in the flue.
CLEANING OUT THE WOOD FIRE
Your wood fire should require minimum cleaning. If the wood fire is operated correctly
according to the instructions most of the ash will be consumed by later fires and a bed of
ash will be maintained that does not build up to any great extent.
If you find that you have to clean out ashes every day or so, it indicates that the wood
fire is not being operated correctly. Either excessively wet wood or foreign materials are
being burnt, or the air control is being turned down too much.
Don’t clean out the firebox completely. Leave at least 25mm of ash in the bottom of
the firebox after cleaning. These ashes in the bottom of the wood fire assist the burning
process, by insulating the firebox and allowing air circulation under the fire bed.
When emptying ashes use a metal container with a tight fitting lid. Do not use this
container for any other purpose. The closed container of ashes should immediately be
taken outdoors to a location well away from any combustible materials, pending final
disposal. If the ashes are to be disposed of by burial in the garden or otherwise locally
dispersed, they should be retained in the container until they are completely extinguished
and cold. This may take several days.
CREOSOTE FORMATION AND NEED FOR REMOVAL
We recommend the flue of your wood fire is inspected before use at the start of the
heating season and also periodically during the season. When you are able to operate
the wood fire without creating creosote deposits, the interval between inspections may
be increased, but the flue must always be inspected and cleaned at least once a year.
The flue should be swept by a professional chimney sweep to remove any build-up of
creosote and soot. A professional sweep should also advise of any problems that may be
detected in the inspection of the flue and offer advice on any repair and replacements.
Your Kent wood fire requires minimal maintenance, and will keep its good looks for a long
time with just a little attention.
