*Items are typically delivered with concrete fireplace structure. It may not suit to position
these items into final location at time of fireplace install, however it helps to use mechanical
lift to place them nearby for an easier 2 man lift into final position.
** A sackbarrow will help to move GRC Woodboxes into position without damaging corners
(Especially if already plastered). Bottlejacks and support blocks are required to support
weight of concrete hearths while aligning bolts.
*** Ensure your crane/ HIAB provider supplies these (Hudson requires 2 x 2.5 ton).
**** Only required if your installation uses infill rather than anchor brackets (see
relevant ‘Trendz Precast Fireplace Design’ Engineers drawings for spec for your fireplace). Due
to volumes required Trendz recommends using concrete from a local ready-mix supplier.
***** This is for when the fire is coming with foundation brackets.

1. All fires must be installed on a concrete footing to
specifications provided in the ‘Trendz Precast Fireplace
Design’ documents. The relevant engineers’ drawings* will be
provided on request. *NOTE: For existing pads refer to note 
below.
2. Ensure the concrete footing is poured on firm ground,
constructed to the dimensions and strength rating
recommended. Allow time for concrete to cure prior to fire
install. If the concrete pad is not flat, plastic shim packers may be
used to ensure fireplace is installed level and plumb.
3. Most fireplace models are poured with a slight taper on the
front and side faces. To ensure your fire is installed level, use a
spirit level on a top flat surface.
4. Existing concrete slabs may be used at client’s discretion for
outdoor installations (if unattached to any building/structure)
however this may void warranty as it doesn’t fall within Trendz
design spec. Pre-existing pads will need to be a larger footprint
than your new fire (+ Wood boxes). We would recommend an
extra mm + on each side.
5. Do not use rapid-set bagged concrete for any part of the
fireplace install. These products tend to expand as they cure and
can cause cracking of the fireplace structure. A standard : ratio
mix (Mpa) is recommended for foundations and concrete infill
of fireplace.
6. Concrete infill (if required) should not be completed until
hearth (optional) is installed. This will not be required if
your fireplace has come with the fire box assembled and has
foundation brackets.
7. The fire should be placed at least 50mm from any
combustible material. Refer to the fireplace spec document for
correct offsets for your installation. We recommend a depth of
mm+ of non-combustible surface in front of the full width of
the fireplace structure.
8. Always burn 2-3 small slow burning fires to season the new
concrete structure. A large fire can cause excess moisture in
the concrete to expand causing concrete cracking or swelling in
plaster/paint finishes.
9. Stresses caused by the casting and curing process can often
cause non-structural hairline cracks (up to 2mm wide) in
precast concrete. These cracks are often invisible until the heat
of the fire causes the concrete to expand. We strongly recommend
that the fire is clad with a modified plaster (e.g., Rockcote) or with
stone/brick/schist or similar. This will hide any hairline cracks that
may occur.
10. Steel fireboxes include several heavy components. Ensure you
have 2 people available to lift these into position.
11. The steel firebox can only be assembled inside the fireplace.
12. The fireplace MUST be finished in either a modified plaster,
stone or brick.

Installation of the fire
. Prior to lifting the Trendz Outdoor Fire into position, ensure
the concrete footing has cured and been constructed to the
dimensions and strength rating recommended.
. Use a HIAB or mobile crane to lift the Trendz Fireplace into
position. Every fireplace has  x . ton swift lift tabs in the top for
lifting. Most hiab trucks carry the swift lift clutches (except for the
Hudson which has  x . ton swift lifts) to connect to the tabs.
. Use crane/HIAB to lift any other heavy components into position,
such as optional wood boxes, concrete chimney extension blocks.
. Complete A) or B) as suits your installation method
A) Site assembly of fire box: Fill the inside of the pre-cast
Trendz Fire with concrete up to the bottom level of the opening.
Ensure the concrete is filled level and flat by measuring and
marking correct height on back of fireplace prior to filling. Ensure
hearth (optional) is installed prior to pouring infill. When the
infill of concrete has cured (- days), assemble the steel fire box
inside the opening. This cannot be assembled then inserted (see
page  for fire box assembly).
B) Pre-assembled fire box option: Remove the fire base plate (D)
and drill and fix the pre-fitted L brackets to your foundations with
the M x  concrete screws supplied.
. Install concrete cap (Douglas) or steel flange (Burton/ Mini
Burton). Do not install stainless steel flue until all cladding/
painting is complete and (optional) steel wood boxes are installed.
. Pre-plastered and painted Burton and Mini Burton:
Place your fireplace on your prepared concrete pad. Remove
the base fire plate (D) and drill and fix the fitted L brackets to the
foundation with the M x  concrete screws. Once complete,
reinstall fire plate. Fit concrete or steel wood boxes if ordered
and then the flue which will be couriered to you.
Packers may be needed to get the fireplace to sit level.
Assembly of the firebox
(Not needed if the fire box is pre-fitted)
The firebox must be assembled inside the cavity. Only finger tighten all
bolts, until the firebox is fully assembled
. Slide the back panel (B) into the fireplace cavity, lean against back
wall of fireplace.
. Slide the two sides (A) into the fireplace cavity ensuring the side
rails are facing inwards and bolt lugs are at rear.
. Bolt the back panel to the sides using the M bolts provided.
. Bolt top baffle (C) to the top of the side panels. To make the install
of this easier, insert a large Phillips head screwdriver through
rear bolt hole on one side of baffle, feed tip of screwdriver into
corresponding hole on side plate. Baffle can now hang on the
screwdriver while the first two bolts are inserted on the opposite
side. After the next two bolts are inserted tilt the front of the
baffle down to make sure the throat opening is -mm before
tightening the bolts.
. Slide the bottom steel fire plate (D) in to sit on the lower side rails
and bolt down. (Install optional hearth first).
. Insert the frame surround (E) and fix to concrete with the dyna
screws provided.  x .mm holes will be pre-drilled in the side
walls of the firebox cavity.
TIP: Fix this in place after plastering and painting has been
finished. Use caution to ensure sharp corners of surround don’t
chip out plaster. Hand tighten dyna screws until sleeve isn’t loose
before inserting, this will prevent the screw spinning in the hole
when you tighten them. Ensure surround is centralised in firebox
opening and screws are inserted flush with surround before
tightening. You may need to tap them in with a hammer. Pull the
fire box forward so it meets the surround.
TIP: If the bottom plate or top baffle aren’t parallel to the
surround, remove bottom plate and place metal packers under
front/back of firebox side plates to level up the firebox. All bolts
must be hand tight only for this procedure.
Care of your fireplace
. Light a small fire - this should be for around - hours. This
process will help your cladding settle and set. Whether it’s plaster,
paint, stone, or any other material, it’s best to slowly introduce it
to the heat of the fireplace. We suggest repeating this process 
times.
. Small cracks are normal - our fireplace shells are made from
concrete, therefore hairline cracks can appear due to extreme
temperature changes; these can be painted over without any
concerns. Over the years, we have worked on perfecting our
concrete mixture so you should not experience any structural
cracking. If you are concerned about the size of the cracks in your
fireplace, do not hesitate to contact us.
. Firebox maintenance - to help make sure that your firebox lasts
many long summers and colder winters, we recommend giving
the firebox a paint with Stove Bright®High-Temperature aerosol
paint in the colour satin black every - months. We also suggest
that you empty fire ashes with an ashpan shovel every - fires.

. Corten steel wood box maintenance - we suggest applying
RIPO (Rust Inhibiting Penetrating Oil) once every - months to
form a rust barrier. The RIPO product forms a water-resistant film
and helps protect steel from condensation corrosion. This can be
purchased directly from our sales team.
. -year warranty - this warranty covers structural cracking and
failure of the steel firebox. This is just another way we guarantee
that you’re getting the best product and service. The warranty
does NOT cover hairline cracks.
Upgrade Installs
Concrete Wood Box:
The wood boxes sit on each side of the fire. A packer may be required
under the bottom edge, to help align with the fire. Two M concrete
screws with a mm washer can be used inside the box at the top, to
hold the wood boxes firm to the fireplace.
Steel Wood Box: (Burton and Mini Burton only)
Place the main top plate over the flue flange. Bolt the side plates to the
top plate using the  x M counter sunk head bolts provided. Fix the
bottom of the side plates to your concrete pad with the M dyna bolts
provided. Make sure the sides are vertical before fixing the base. Keep
the steel looking sharp by applying Trendz Ripo Oil every - months.
Hearth:
Insert the mm galvanised bolts through the pre-drilled holes in the
precast concrete fireplace and through the holes on the hearth, with
the nut on the hearth side. Place a mm washer behind the nut, and
the head of the bolt. Do not over tighten, as this can cause the hearth
to crack. With the polished hearth, the  x M bolts thread into  x
thread inserts which are cast in the concrete - xmm washers inside
and xmm washers outside*. If plastering on-site, bolt washers
(xmm) in place first and plaster around them.
PLEASE NOTE: The hearth is NOT designed for adults to sit or stand on.
Chimney Extension Blocks (mm):
Insert  x D reinforcing rods into the top of the chimney with the
chemical anchor adhesive supplied. Add a bed of mortar between the
chimney and the extension block. Thread the extensions blocks over
the rods. For additional extension blocks, add a bed of mortar between
each block. Make sure the bed of mortar goes fully around each mm
hole. Fill the cavity around the rods with mortar. If the flue is going
through the roof, it needs to be installed to the standard NZ.
Plinth:
Place the plinth on your concrete foundation. (See Trendz engineering
drawings for foundation design). Plinth has  x .T swift lifts on the
top, so you will need  of the .T swift lift clutches. Fix the plinth to
the foundations with the  x L brackets and M x  concrete screws.
Place your fireplace on to the plinth with the rear of the fireplace flush
with the back of the plinth. Bolt the fireplace to the plinth with the  x L
brackets and M x  concrete screw bolts.
Square Chimney: (Burton)
Place a generous bead of adhesive on top of the structure mm inside
where the chimney is going to sit. Screw the two mm threaded rods
into the inserts in the base of the concrete chimney. Place the chimney
on the structure with the base of the chimney flush with the back of
the structure. Fix the  x  washer and M nut on the end of the
threaded rod.
S/S Square Cap:
(Douglas, Hudson, and Burton square chimney)
Fit the cap legs into the mm deep holes in the top of your concrete
chimney. The legs can be glued in if desired but is not critical. The cap
should be no closer than mm to the top of the chimney.
Anti-Down Draft (ADD) Cowl:
Fix the flashing plate to the top of the chimney with four small masonry
screws and silicon. Rivet together the flue and ADD Cowl. (This is for
the Douglas, Hudson, and Burton square chimney). The ADD cowl for
the round flue on the Burton and Mini Burton just slides inside the flue
and doesn’t need to be riveted.
Flue: (Burton and Mini Burton only)
Bolt the stainless-steel flange to the top of the concrete structure
with the  x M x  dyna bolts provided. If plastering the top of your
fireplace, it is best to plaster over the base of the flange and the bolts.
If your fireplace is pre-plastered, your flange will already be in place.
Slide the black flue over the flange once plastering or stonework is
complete.
