The Nature of Wood
The timber provided for your log cabin is soft wood which has been kiln dried and is untreated, except for the bearers. Wood is a
natural material and may have knots, knotholes, cracks, warping and imperfections. These are inherent properties of the material
which gives wood its natural character.
It is not necessary to replace any lengths of timber for the following reasons:
•Any timber that contains knots or knot holes where they do not interfere with the structural stability of the cabin.
•Cosmetic appearances - e.g. colour variations caused by the structure or age of the timber.
•Timber that has shakes, cracks or gaps that do not influence the structural strength of the cabin.
•Twisted/warped timber that can be installed. See the 'How to install twisted/warped timber' section for help with installing
twisted/warped timber.
•Boards that have imperfections, for example any surface defects in the roof or floor boards can usually be hidden by turning
the affected surface so that any unwanted features are hidden from view.
•Dunster House Ltd will not freely replace any parts that are damaged due to any neglectful workmanship when your cabin is
being built. However, replacement parts are available to purchase, please contact our Parts department at
[e-mail].
Any valid queries will be satisfied by the exchange or replacement of the defective parts only.
Treatment
•You will need to treat your cabin with a suitable timber treatment once the cabin has been built.
•We recommend using a treatment that contains a water repellent, if your treatment does not contain water repellent we
recommend applying one afterwards.
•You will periodically need to re-apply any treatment.
•If you have purchased wood treatment from Dunster House Ltd, we will supply enough to coat your cabin exterior twice.
•Take care not to apply any treatment too thickly as this may 'glue' the logs together and restrict their natural movement.
The logs must remain free floating.
Getting ready for construction
Prior to assembly, store all components in a cool, dry place away from direct contact with the ground, sunlight and moisture. If
storing the timber for any prolonged period of time, keep all timbers straight and well supported at numerous points along their
lengths to avoid twisting the timber.
When selecting the location for your cabin, ensure that the cabin will not be subjected to extreme weather conditions. If your
cabin is in an area where strong winds often occur, you should take additional precautions, not detailed in these instructions, to
secure the cabin as it is not designed to withstand high winds.
Note: Sunlight will bleach timber and moisture will warp timber.
•Always check all parts are present and correct prior to commencing the cabin construction or arranging/paying for third
party help.
•Allow sufficient time to familiarise yourself, or your nominated installer, with the instructions prior to building your cabin.
When the instructions ask you to use screws - you must pre drill holes for the screws to avoid splitting the timber.
Preparation for Assembly
To build your cabin you will/may need:
•2/3 people - there are some heavy components
•Hammer - nailing roof and floor boards
•A stepladder - to safely work at height
•Sharp knife - cutting shingles / roof material
•Spirit level - check everything is plumb and level
•Silicone Gun - seal the glass in the windows / doors and wind braces
•Staple Gun - stapling waterproof membrane, felt or shingles
•Screwdriver/drill - pre drilling holes for screws
•Drill with 3mm and 8mm drill bits - remember to pre-dill holes for screws and bolts
•Socket wrench with 10mm bit, or adjustable spanner - fixing storm brace and hex screws
•Saw - cutting trims & floor/roof boards
•Measuring tape - measure twice cut once
•Tarpaulin/plastic sheeting - to cover the floor or protect from the elements
•Pair of clamps - help to hold timber in place during assembly
•Gloves - if you wish to use protective gloves as a precautionary measure
•Rubber Mallet - to gently persuade logs in to place
•Sandpaper - to smooth out any rough patches

Assembly Instruction
Instructions are available from our website - https://dunsterhouse.co.uk/customer-login-area/log-in.
If you require a PDF via email, please contact our customer Services department - [e-mail].
Missing/Damaged Components
There are spares of some components within the pack which can also be cut down if necessary and used where applicable. These
spares are identified in the component list. In the event the spare is not suitable please email our Customer Services department -
[e-mail] and include the component number of the part along with the dimensions and your order number
starting with "SO", or your postcode.
If a notch is damaged on a piece of timber this can easily be remedied. Hold the broken notch in place and pre-drill a hole through
the log into the notch. Do this in the groove so the screw is hidden. Glue the face of the broken notch, hold it in position and
screw through the log into the notch, this will secure it in place. Wipe off any excess glue.
Troubleshooting - Doors
Door Locks
If your door is not locking correctly please check the following:
•Open the door and turn the key, does the deadbolt come out of the locking mechanism?
No - contact our Customer Services department at [e-mail], who will help you check if the lock barrel or the lock
mechanism is faulty. If it is faulty our Customer Services department will organise a replacement as soon as possible.
Yes - The following steps will remedy misaligned locks:
•Open the lead door and use the key to 'lock the door' this will push out the deadbolt. Push the door to so that the deadbolt
rests against the slave door and mark the position of the deadbolt on the slave door. Open the lead door and check if the
deadbolt lines up with the position of the receiver.
•If the receiver does not line up correctly then one of the following solutions should remedy this.
•Check the door sashes - if a door sash has dropped, you will need to adjust the position of the hinges to reposition the door
lock in alignment. Remove the sash and partly unscrew some or all of the hinges and reposition the sash to see how the door
hangs. Do not unscrew the hinges far enough to expose any thread.
•If the above is not possible it may be easier to reposition the receiver. To do this, remove the receiver, chisel out a bigger
hole where necessary and reposition.
•Heel & toe - the glass in the doors may have dropped (sealed units only) and will need to be heel and toed.
Door Closed and Stuck
If your door is stuck in a closed position please perform the following:
•If your door is stuck closed in a locked position, try and turn the key in the opposite direction to normal and then in the
normal direction, this can help to free a stuck mechanism.
•Lift the lead sash under the handle and push the sash upwards whilst turning the key to try and unlock the door. This
happens when a door has settled and dropped too much, the pressure of the door weight on the lock can cause the lock to
become stuck. Pushing up on the door handle as you unlock it will release the pressure and allow you to check the lock. If the
lock is not faulty you may need to adjust your door hinges or toe and heel if you have sealed units.
If after trying all of the above your issue is not resolved then please contact our Customer Services department at
[e-mail].
Timber
Splits/Knot Holes and Sap
Timber is a natural material with inherent properties which include splits, shakes, warps, cracks and knots. Typically these will
not affect the integrity of timber. However, if you have a component with one of these features that you feel may cause an
issue, then please send a photograph with the component number to our Customer Services department at -
[e-mail]. so we can assess if a replacement is needed. Sap is perfectly normal occurrence within timber and
is not harmful. It can be left to dry and gently cut off with a sharp knife.

How to install twisted/warped timber
Timber is a natural product and unlike extrusions made from plastic or metal is likely to twist due to the nature of the material.
Warped timber is unavoidable particularly with soft wood and is more common in longer and larger sections. Warping can occur
even once a product is packed. We have accounted for this natural quality of timber in the design of our timber products so
that the installation of twisted or warped timber is possible. It is worth bearing in mind that with all these techniques it is very
unlikely that the logs will straighten perfectly. The point is that they will straighten to the extent of allowing the cabin to be
built or the part fitted as it is intended, within the limitations of the material used.
Tips & tricks
•Avoid using warped timbers on the first layer of logs (the ones that are screwed into the bearers). If the first 'half log'
is warped then use clamps and additional screws to straighten and fix it onto the bearers.
•Use warped timbers lower down in the cabin rather than higher up, it is easier to manipulate them lower down in the
wall. Once manipulated into position the weight of the cabin will then help to keep them straight.
•Twisted bearers - use the most twisted for the end bearers which are doubled up and screwed together. Place the
twists so they counteract each other, use additional screws to fix together to help straighten out the timber. The first
'half logs' are then fixed onto the double bearers aiding the straightening out process coupled with the weight of a built
cabin.
•Top logs - as these logs are angled they need to be fitted at the top. When sorting your logs for assembly, check these
logs. Wet and weight them from the start of assembly to give them a chance to straighten. To fit the roof boards onto
a warped top log, you can temporarily screw the top log to the log below. Use a spare piece of timber screwed to the
side of both logs to help keep the warped log in position. Keep the spare piece of timber screwed in position whilst you
fit the roof and remove once the roof is completed.
•A rubber mallet and hitting block (packing piece or off cut of timber) can be used to help warped logs into position. Start
with engaging the notches at one end and work along the length of the log. Hit from the side towards the tongue and
then down onto the timber to gently engage the notches of both logs together. Work your way along the length of the
log knocking it down into place. Be careful not to damage the tongue or notches.
•Wet, weight and wait! - Lay the timber out on a flat and level surface. Wet and weight by applying heavy objects to flatten
the timber. Wet the timber but not to the point of saturation, using a spray bottle is best. This may take several days
however it is not uncommon to see results after 24 hours.
•Clamps - Use two clamps as handles, one at each end of the log with blocks of wood to protect both sides of the timber
from the clamp grips, and twist the timber to near vertical whilst lowering it into the notches of the wall sections below.
A rubber mallet and hitting block can be used to ease the log into the tongue and notches of the log below. Start at one
end and work your way along the length of the log. Be careful not to damage the tongues or notches.
•Remember there are spare logs in the pack and they can be cut down if needed to create a smaller length log.

All dimensions are approximate and subject to the limitations of the material used and the methods of manufacture
Front
The minimum overall base dimension should be 100mm bigger than the external dimensions of the cabin. Only a completely level and stable load bearing
foundation should be used as a base for your log cabin. Failure to do this may lead to installation issues and diminish the integrity of your log cabin.
Screw the 2 outer bearers together with 50mm screws at 400mm intervals leaving a 25mm interval at the either end of the bearers.
Pre-drill 3mm pilot holes for all screws to avoid splitting timbers.

First Wall Logs
IMPORTANT - Ensure that the base of the bearers and first layer of
wall logs are level and square. Continue to check if the cabin is
square by measuring the diagonals and that the walls are level
at least every 4 layers of logs.
•The first layer of logs should overhang the bearers by 5mm on all sides.
•Fix the first layer of logs to the bearers using 70mm screws, at 400mm
intervals. Pre-drill 3mm pilot holes for all screws to avoid splitting
timbers.
Front & Rear Right & Left
•Once the first layer of logs are in place, check that the diagonals are
equal A=B, failure to do this may lead to problems later.
•Continue laying wall logs as per the specific wall layouts of your cabin.
•Use a hitting block and hammer to ease the wall logs into place.
•The tongues should face upwards.
•DO NOT hit the tongues directly as this may damage them.
NOTE - The layout of your doors and windows can be changed by installing the relevant logs on
the opposite side of the cabin or the opposite side of the front wall. The position of the XN logs
cannot be changed and need to have the top angle sloping outwards from the middle of the cabin.
IMPORTANT -Ensure the bearer layout and cabin is square by measuring the diagonals. If you do
not square the cabin it may result in problems when installing the roof.
PLEASE NOTE - The images used are for reference only. The configuration of your wall logs and
bearers may differ from the cabin shown.

DOOR AND WINDOW INSTALLATION
Wood is a natural material and will 'move' over time, therefore windows and doors need to be 'free to realign' if the wall
logs 'move'. We have accounted for this natural quality of wood and the movement that can happen in the design of our
timber products.
Secure the window and door frames with the 35mm hex nut screw and washer through the countersunk slotted hole in the
top bar of the frame. Pre-drill 3mm pilot holes for all screws to avoid splitting timbers. Position the hole/screw towards the
top of the slotted hole. Do not tighten the screw fully, this will allow the frames enough freedom of movement to realign
vertically but stay in position horizontally. Attach the Dunster House logo plate to hide the screw and slotted hole when the
frame is fitted.

Sealed units are approximately 10mm smaller in length and width than the
aperture. This difference in size will be packed using bridge packers (4mm),
black shims (2mm), and green shims (1mm). Bridge packers must be used
only against the frame, while shims are to be used only next to sealed units.
The shims should be used to fill any remaining gap between the sealed unit
and bridge packer to ensure a tight fit.
Glazing Windows and Doors
1. Remove the uPVC glazing beads from the frame one by one and
mark on the inside "top", "bottom", "left" and "right" accordingly with
a pencil to allow for correct reinstallation.
2. Place the bridge packers on the frame as per drawing so that they
lie flat and parallel to the frame, with the channel side towards the
frame and the ridge side facing upwards to allow for correct drainage.
Packers must not cover drainage holes in frame.
3. Place the sealed unit into the aperture, allowing approximately
5mm around the sealed unit and pack according to window or door
type. Use shims to ensure a tight fit.
4. Apply silicone (not supplied) to frame, packers and shims to hold them in position. DO NOT apply silicone to bridge
packers at the bottom of frame, this could block the drainage holes.
Packer locations
French doors-Place black bridge packers in lower hinged corner and in the upper floating corner (diagonally across) to
ensure the unit is correctly heel and toed. French doors should also be packed at the centre of the sealed unit for easy
operation and security.
Windows (Top Openings) - It is paramount that these sashes are correctly packed at the sides and bottom
Windows (Fixed units)- Should be correctly packed only at the bottom of sealed units.

5. After packing the sealed units correctly, refit the beads in the same position as you removed them; start with the
smallest lengths first before inserting the longer lengths. Carefully use a nylon or non-marking rubber mallet to help tap
the beads into position, starting at the ends.
Occasionally beads can become slightly difficult to install due to friction. Use a spray bottle to apply a little water to the
sealed unit where beads will be installed then carefully tap the beads into position. You should only tap the beads as
tapping sealed units may cause damage.
Glazing Windows and Doors
French doors- Once doors have been fitted and heel and toed correctly, the top and
bottom shoot bolt keep may require minor adjustment. Adjust top plate by slightly
loosening and retightening the two top plate screws. Finally fasten the top plate through
the locating hole using a 19mm x 3mm Philips head countersunk screw (not supplied).
Checking
Make sure all opening sashes work. Should they not work, then it is likely that the sealed unit has been incorrectly packed.
The sealed unit must be removed, re-packed and reinstalled. Failure to do this can result in locks not engaging properly,
daylight being seen, a lack of weather protection and possible contacting on locks or on the bottom of the sash when
closing. If you have any of these problems, to rectify, check:
•Your installed item is square, level and plumb in the aperture and is not twisted in any way. Test for squareness by
checking that both the frame and any sashes diagonal measurements are equal.
•That the frame has not bowed by over-tightening the screws (especially in a door).
•Ifminor(mm) adjustments are requiredaftercorrect glazing, all our hinges have minor adjustment capabilities.
•All our windows and doors have adjustable cams located on the locking strips. Using an Allen key, these can bring the
window or door sash tighter or less tight to the frame.
•The small latch plate to the locking mechanism of the door is adjustable by using a Phillips screwdriver and rotating
each screw half a turn to loosen the plate. Reposition, then tighten screws.
•Hook bolt latch plates are adjustable by rotating the cams using an Allen Key. Move inwards to tighten the door to the
frame to give maximum security.
De-glazing
Starting in the middle of the longest bead, use a sharp chisel, wide blade spatula or putty knife to apply pressure
between bead and frame to separate. Once removed, repeat on adjacent bead.
Having carried out these checks and adjustments if issues still exist, please contact our Customer Services department at
[e-mail] with your order number ready to discuss your requirements.

UPVC French Door Handle Installation Page 17
•Parts required for door handle installation are attached to the door sash in a small box.
•Place the blue spring cassette in position as shown.
•Repeat this for both internal and external handles. This will stop the handle from freely spinning.
•Slot the spindle into the internal handle and
feed into the internal side of the door sash
via the spindle hole.
•Allign this with the external handle on the
external side of the door sash.
•Use the 2 longer screws and a cross headed screw driver to
secure the two handles together.

uPVC Doors with uPVC Frame
Compress the door frame with clamps before drilling.
Use packers / shims to ensure that the door / window frames are equally spaced on both sides.
The door / window frames also need to be vertically aligned with the base (90 degrees) before continuing.
Position the door / window with frame into the aperture (from the outside) and ensure the diagonals are equal (A=B).
The following principles apply for both doors and window.
The glass, uPVC glazing beads and timber trims are to be put to one side for the moment.
Firstly, remove the uPVC glazing beads from both of the doors and window (refer to previous page).
