Stage 1 - Construction and preparation of the wall opening/cavity
WARNING! Important Information
• Access is required to fit the flue spigot adaptor to the Mega
Smart firebox and for installation of the ECO Built-In flue kit.
Pioneer Manufacturing recommend lining the walls of the
enclosure after the Mega Smart and flue kit have been installed.
• As the Mega Smart is built into an enclosure, the enclosure
must be vented using one of the options detailed on page 4.
Construction of the timber framed enclosure
1. Frame up the enclosure to specification. Combustible framing
materials are acceptable but a fire resistant wall board is required for
the fascia to sit against such as 9mm Promina board or equivalent.
Framed cavity internal dimensions
Internal width 925mm +/- 5mm
Depth including wall lining 675mm +/- 5mm
Height to underside of lintel 855mm +/- 5mm
DIAGRAM 1
Wall lining opening dimensions
Height 818mm +/- 1mm
Width 925mm +/- 5mm
Flue centreline 445mm
*Please note: If a brick front is to be built you will need to allow for
the thickness of the bricks.
Make sure the floor where the fire will sit is level and flat as any
discrepancies will make it difficult to slide the fire into place and align
the fascia correctly. Also be precise when cutting the opening as the
fascia will only cover the top of the opening by 7 or 8mm.
Please ensure you maintain the minimum air gaps between the Mega
Smart cabinet and combustible material inside the cavity as below:
Top Sides Rear
Air Gap 30mm 27mm 39mm
2. For an ‘elevated’ installation we recommend you fix additional framing
beneath both sides and mount runners of the VZCC to support the
installation. You will also require additional framing to fix the wall
lining below the VZCC. The VZCC box can sit directly on the framing
but we recommend fitting a floor to provide seismic fixing points for
the VZCC. Insulation is not required under the VZCC.
For elevated installations, the floor protector may be installed after
the wood fire is in position as it does not extend into the enclosure.
However, the floor protectors rear edge must butt up against the non-
combustible wall lining below the heater, and the joint at that point
must be sealed to prevent the possibility of ember penetration.
3. A 1200mm x 1200mm sheet of 9mm Promina board or equivalent
non-combustible material is required around the fascia as illustrated
in Diagram 1.
It is usually convenient to carry the same lining material right up to
the ceiling level. The side lining of the enclosure may be standard gib
board or any other wall lining material.

WARNING! Important Information
RECOMMENDED WALL LINING IS 9mm PROMINA BOARD
OR EQUIVALENT NON-COMBUSTIBLE MATERIAL. PLEASE
CONTACT THE RELEVANT MANUFACTURER FOR PRODUCT
SPECIFICATIONS IF YOU CHOOSE TO USE A PRODUCT OTHER
THAN PROMINA BOARD. FIRE RATED GIB BOARD IS NOT AN
ACCEPTABLE MATERIAL TO USE AS AN EQUIVALENT.
Please note: Wall surfaces directly above the fascia may reach high
temperatures, so materials such as wallpaper and water based paint
may be adversely affected. For durability of finishes and surfaces you
should contact the relevant manufacturers for their specifications. Pioneer
Manufacturing Limited accepts no responsibility for the deterioration of
surfaces of finishes.

Stage 1 - Construction and preparation of the wall opening/cavity
Venting through the ceiling space of the home
A
CAUTION! Important Information
AS THE MEGA SMART IS BUILT INTO AN ENCLOSURE,
THE ENCLOSURE MUST BE VENTED USING ONE OF THE
FOLLOWING OPTIONS.
A. VENTING THROUGH THE CEILING SPACE OF THE HOME.
B. VENTING THROUGH THE CAVITY WALL.
C. VENTING THROUGH AN ECO OPTION KIT.
Cavity venting requirements
As the Mega Smart Built-In is built into an enclosure, the enclosure must
be vented using one of the three options detailed below.
Venting through an external wall will require suitable precautions to prevent
rodents and debris from entering or restricting the air vents. If grilles are
used, the minimum vent area must be maintained through the grille itself.
It is the responsibility of the installer to ensure the requirements of New
Zealand Building Code Clause E2 (External Moisture) are complied with.
The enclosure is constructed to the full height of the room and is fully
open/vented into the ceiling cavity of the home.
Venting through the rear wall of the cavity
B
A minimum open unrestricted vent area of 32,000mm2 is required to cool
the outer cabinet and flue liners within the combustible structure. This vent
can be positioned in the rear wall or floor of the cavity, but venting through
external cladding will need to be vermin proof and increased in size to
ensure the minimum unrestricted open area as specified.
Venting through the ECO Option Kit
C
Venting through the top of the enclosure using the ‘ECO Option Kit’ with
the Metro ECO Built-In flue kit. If you choose to vent the enclosure with
this method there must be no internal ceiling or 2nd storey floor blocking
airflow within the cavity. The cavity must be fully open vertically from
the outer cabinet to the enclosure capping/flashing plate as indicated in
Diagram 2 below (Venting through the ECO Option Kit). Please see
Diagram 5 for the ECO Option Kit installation.

Stage 2 – Installation of the Mega Smart Built-In
CAUTION! Important Information
It is critical for the safe and efficient operation of the Metro Mega
Smart Built-In, that the front edge of the outer cabinet MUST BE
FLUSH with the front edge of the wall lining. Frequently at time of
installation the wall lining may not be complete, so if 9mm promina
board is being used to cover the framing, the installer will need to
have the front edge of the base panel 9mm forward of the framing.
Similarly if a brick facade is being constructed, the installer must
move the VZCC forward so the front edge of the base panel ends up
flush with the front face of the bricks once constructed.
If you are fitting the water heater to the Mega Smart built-in, please
refer to the installation instructions included with the water heater.
The Mega Smart booster is designed to fit externally to the firebox
on either side and is best fitted prior to installing the fire into the
enclosure.
Installing the Mega Smart Built-In firebox
1. Remove from within the firebox the plastic bag containing the
component kit, two firebricks wrapped in cardboard and the top baffle
assembly.
2. Position the Mega Smart Built-In into the wall opening you have
created. Slide the Mega Smart Built-In into place and check it is
central by ensuring the clearance between each side of the outer
cabinet and the sides of the opening are equal. The front edge of the
Mega Smart Built-In outer cabinet MUST BE FLUSH with the front
face of the wall lining (Refer Diagram 3).
DIAGRAM 3
3. Secure the Mega Smart Built-In to the floor through the two restraint
holes provided in each corner at the front of the cabinet. Masonry
anchors are required for a concrete floor and wood screws for a
timber or particle board floor.
Note: The Mega Smart Built-In must be secured rigidly to meet the
seismic restraint requirements of AS/NZS 2918:2001
4. Using a 10mm spanner, remove the two bolts holding the air slide
spacers which are located at the top, front of the firebox, ensuring the
control arm of the air slide is located on the right side of the firebox.
Attach the air slide to the firebox using the two bolts and spacers.
5. Position the 200mm/250mm diameter liner spigot into the top of the
cabinet centralising it with the centre of the flue spigot. Secure the
liner spigot into position using the 12 self tapping screws supplied.
6. Unwrap the two firebricks from the cardboard wrapper and fit the side
bricks to each side of the firebox.

Stage 3 - Installation of the Metro ECO Built-In flue kit
CAUTION! Important Information
• As detailed within AS/NZS 2918:2001, it is not allowed to
mix flue systems or components from different suppliers or
manufacturers. The spigot adaptor supplied with the Metro
Mega Smart is Metro flue system components designed to
mate up with the Metro ECO Built-in flue kit. Only the Metro
ECO Built-In Flue Kit can be used for installation with the Metro
Mega Smart Built-In wood fire.
• The top of the flue must terminate a minimum of 4.6 metres
above the top of the floor protector, the ‘active’ 150mm
diameter stainless steel flue pipe must be fully encased with
both 200mm and 250mm diameter flue liners/casings over
its entire length, and the flue system and its installation must
comply with AS/NZS 2918:2001. Additional flue system
installation criteria is detailed below.
• As the flue system is to be enclosed in a structure replicating
a conventional masonry chimney, the base of the weather
cowl must be a minimum of 250mm above the top of the false
chimney. (Refer Diagrams 4 & 5)
ECO Built-In flue kit assembly and installation
The Metro ECO Built-In flue kit is comprised of 3x Metro ECO Extension
Kits and a Metro ECO Cowl. Each extension kit includes a 1200mm length
of 150mm flue pipe, 200mm and 250mm inner and outer liners required
for this installation.

1. Penetrate the roofing material on the flue centerline. Cut roof cladding
to the same diameter as the outer liner and bend up edges to create
both moisture stop and clearance.
2. Nog around the flue liner allowing a 25mm clearance. If you’re
installing the ø300mm ECO Option Kit liner, this can be directly fixed
to the timber framing at four points as shown in Diagram 5.
3. Secure the flue pipes together and ensure the flue seams are
staggered. The flue pipe sections must be fixed together at each joint
with at least three monel or stainless steel fasteners, and the crimped
ends of the flue inner and outer casings go to the top. The joints
of the flue pipes must be sealed with Pioneer fire cement. Prior to
installing the assembled flue pipe into the chimney cavity, take careful
note to ensure there are no overhead power lines in close proximity.
4. Lower the assembled flue pipe with the crimped end fitting into the
flue spigot of the firebox. With the flue pipe in position and sealed
with Pioneer fire cement into the flue stub, pilot drill through the hole
provided in the front of the flue stub into the stainless steel flue pipe
and secure with the M6 bolt and nut supplied in the plastic bag with
the Insert model firebox.
5. Lower the inner casing and engage it with the 200mm diameter inner
liner spigot, repeat this step with the outer casing and engage it with
the 250mm diameter outer casing spigot of the VZCC.
6. When the flue system is in its final position, the top of the outer casing
must be above the ridge line or roof as indicated in Diagram 6, as per
AS/NZS 2918:2001.
7. While still on the ground, assemble the ECO Cowl as follows;
(G)
- Take the stainless steel weather butterfly (A) so the angled sections
are facing up.
steel weather butterfly (A) facing up, fit it into the stainless steel ECO
Cowl top (B), and secure in position through the holes provided with
stainless steel rivets.
Please note: Once fitted the weather butterfly will be slightly angled
within the cowl housing.
- Fit the ECO Cowl top (B) into the ECO Cowl housing (C). Push both
sections together until the swage ring on (B) rests completely on the
open end of the cowl housing (C). Drill through the two pre-punched
holes in the ECO Cowl housing and secure these two sections together
with stainless steel rivets.
The removable section of the ECO Cowl is now fully assembled.
8. Making your way back onto the roof, ensure the outer casing (F) is
‘level’ (+ or -10mm) with the top of the 150mm stainless steel flue
pipe. Using a suitable flashing, weather proof the joint where the
250mm diameter outer casing penetrates the roof. Ensure the flashing
used is compatible with the roofing material, and if fitting instructions
are supplied with the flashing, these must be adhered to.
With both arms and angled sections of the stainless

Stage 3 - Installation of the Metro ECO Built-In flue kit
9. Fit the 480mm long flue pipe extension/flashing cone (D), with the
flashing cone at the bottom, fit its short flue section inside the top
of the already installed 150mm diameter flue pipe. Ensure the three
brackets extended below the flashing cone fit ‘outside’ the outer
250mm casing. Drill through the pre-punched hole in all three
brackets into the outer casing and secure with rivets.
10. Taking the removable section of the ECO Cowl, position it over the top
of the stainless steel flue pipe extension, and slide it down fully. This
removable section does not require riveting and enables easy removal
for future flue cleaning.
Flue termination methods
Assess the following aspects to determine the upper flue termination.
These methods can be used on either sloping roofs or false chimney
chases. Where the fire cabinet / flue liners cannot be vented from the
ceiling cavity or other means, an additional venting liner can be installed on
any termination design similar to that in Diagram 5.
Option 1 - ECO Built-In flue kit without air supply vent (Diagram 4)
Nog out framing to achieve a square aperture measuring 300mm
internally to allow a 25mm clearance around the outer liner. A non-
combustible capping is desirable with compatible weather flashing.

Option 2 - ECO Built-In flue kit with additional air supply vent (Diagram 5)
Nog out framing to achieve a square aperture measuring 300mm internally.
The ø300mm ECO Option Kit liner can touch timber in four points for direct
fixing into the timber framing. A non-combustible capping is desirable with
compatible weather flashing.
Flue System Minimum Heights (In compliance with AS/NZS 2918:2001)
250mm
minimum
The Metro ECO Built-In flue kit complies with AS/NZS 2918:2001 and
its 4.6m height requirement (4.6m minimum from the top of the floor
protector to the top of the flue pipe).
If the flue centerline is within 3m from the ridge, the outer casing must
end at least 600mm above the ridge. If it is further than 3m from the ridge,
the outer casing must extend at least 1000mm above the point of roof
penetration.

Stage 4 – Construction and installation of the floor protector (hearth)
Non-combustible floor (Ash Floor Protector)
CAUTION! Important Information
If the Mega Smart Built-In is to have a raised floor protector, the base
on which the Mega Smart Built-In firebox will be installed needs to be
raised to the same height. (See diagrams opposite)
Pay particular attention to making sure the floor where the fire will sit
is level and flat as any discrepancies will make it difficult to slide the
fire into place and to align the fascia correctly.
All installations of the Mega Smart Built-In onto a concrete or non
combustible floor structure only require an ash hearth floor protector
that complies with AS/NZS 2918:2001 and this installation manual. (See
Diagrams 9 & 10 opposite).
If the floor structure in front of the installation is non combustible (e.g.
concrete) the floor protector may be omitted. However, if heat sensitive
floor coverings (e.g. carpet) are fitted it is still necessary to keep these clear
from the appliance to the minimum distances specified in the table below.
Combustible Floor (Insulated Floor Protector)
All installations of the Metro Mega Smart Built-In require an insulated
floor protector that complies with AS/NZS 2918:2001 and this installation
manual. This Floor Protector must be a minimum width of 1057mm and a
minimum overall depth of 505mm.
Minimum overall depth is the distance from the front of the wall lining
(behind the fascia) to the front point of the Floor Protectors non-
combustible surface. The Floor Protector must have an insulating rating
which is equal to or greater than 26mm thick Eterpan LD. Recommended
construction of tiles on 26mm thick Eterpan LD board or equivalent.

In this case, if tiles or similar are required for decorative purposes, they
can be fixed directly to the concrete floor. This will make the top of the floor
protector approximately flush with the floor covering. The tiled area must
project out a minimum of 505mm from the front of the wall lining (behind
the fascia) and must be a minimum width of 1057mm.
Please note: You will need to raise the Mega Smart Built-In firebox by the
same amount as the thickness of the tiles fixed to the concrete floor. (see
Diagram 10)
For elevated installations, the floor protector may be installed after the wood
fire is in position as it does not extend into the enclosure. However, the floor
protectors rear edge must butt up against the non-combustible wall lining
below the heater, and the joint at that point must be sealed to prevent the
possibility of ember penetration.

Stage 5 – Fitting the Mega Smart Built-In fascia
On a flat surface (a floor) open the fascia carton and remove the door.
Taking the door in both hands, with the spindle end in your right hand
and the outer face of the door facing you, attach the door to the firebox as
follows;
1. With the door in a 45 degrees open position, allow the lower hinge
pin on the bottom left hand side of the firebox to pass into the hole
provided in the bottom of the door frame.
2. Lift the door until the top of the door frame passes over the top of the
hinge pin, align the hole provided on the top face of the door frame
and lower it down over the top hinge pin.
3. Take the door handle from the plastic bag and screw it onto the door
spindle by turning it clockwise.
4. To fit the fascia, ensure the four speed clips provided are positioned
over the large diameter mounting holes in the four tabs located in the
front of the cabinet (fascia mount points).
5. Attach the fascia with the four longer screws that are supplied in the
plastic bag, taking care that the air control lever passes through the
slot provided in the fascia. Centralise and level the fascia on the fire
box insert door and secure the four screws.
The fascia should be evenly spaced around the door frame and sit
evenly against the wall lining when the firebox cabinet has been
correctly positioned. (The door can still be removed from the fire with
the fascia in place when it is correctly fitted).
Mantel clearance
A timber or combustible mantel must not project more than 150mm from
the finished wall lining and there must be a minimum distance of 500mm
above the top of the Mega Smart Built-In fascia to the underside of the
mantel. If the clearance is less than the minimum specified, a heat shield
will be required to be fitted under the mantelshelf in accordance with
AS/NZS 2918:2001.

Congratulations on the purchase of your Metro wood fire
This low emission, slow combustion appliance is designed to give you many
years of warmth and service, subject to the following key factors. These key
factors, if not adhered to are the major causes of unsafe installation, poor
performance and flue blockages and potential product failure.
1. Your Metro wood fire must be installed correctly. Metro recommend a
competent and suitably qualified NZHHA installer.
2. The only fuel to be used in this appliance shall be wood that meets the
following criteria.
– Less than 25% moisture content
– Has not been treated with preservatives or impregnated with
chemicals or glue,
– Is not chipboard, particle board, or laminated board,
– Is not painted, stained or oiled
– Is not driftwood or other salt impregnated wood
3. The appliance shall be operated at all times in accordance with the
“Installation and Operating Instructions” supplied with each appliance.
4. It is preferable that Metro wood fires should be installed with a Metro
ECO Flue System.
5. Coal must not be used as a fuel.
Please also note the following important points:
• In New Zealand a building consent is required from your local building
authority. The homeowner is responsible for obtaining this consent
• As correct installation is critical to the performance and safe operation
of your Metro, it is recommended your Metro be installed by a NZHHA
registered installer or a person suitably qualified in the installation
of wood fires. Your Metro retailer will be able to arrange professional
installation for you
• During the very first fire your Metro will give off an odour and fumes
as the firebox paint cures. Do not be alarmed; open all windows and
externally opening doors in that room and close any internally opening
doors. This curing process will last for approximately one hour and is
likely to happen this one time
• Properly seasoned (dry) timber is necessary for the Metro to operate
efficiently; firewood that contains a high moisture content will result in
flue pipe blockages, reduce heat output and create other issues.
Note: Once split, Softwood usually takes 12 months to season - Hardwood
can take up to 24 months to season - Wood must be stored in a location
that enables air circulation. Unseasoned wood stored in a closed woodshed
without air circulation will still be unseasoned 12 months later.
• It is critical that the fire not be operated with over worn, faulty or missing
door seals. Door seals will harden over time and become over-worn (3-4
year’s) this will cause air to leak into the fire, causing the appliance to
‘over fire’
• It is critical that the fire not be operated with over worn, faulty or missing
bricks, baffle plate, promet extension (white board on the baffle plate)
• It is critical that the fire not be operated with cracked or broken door
glass.
Please note, the above 3 points require regular inspection/maintenance
(every time the ash bed is cleaned out, generally 3-5 times a season) and
if not maintained will void the firebox warranty. A glowing firebox or lower
fluepipe is just one sign you are over firing your appliance. Please ensure
you keep your proof of purchase/receipt on any parts you purchase.
• For optimum performance fuel must be loaded so the logs lay “front
to rear” in preference to laying across the width of the firebox. Spaces
should be left between the logs to enable oxygen to get to as much of
the surface of the fuel as possible
• A small hot fire loaded frequently is more efficient than a large fire
burning on a low setting
• Your Metro is covered by a full unconditional 12 month warranty on
replacement parts, and a 10 year firebox warranty.

Where to install a Metro wood fire in your home
Wood fires are usually installed in the main living area, which is the section
of the home that is usually kept the warmest, being the area in the home
most frequently occupied. However, before deciding on the best location
for your Metro wood fire you may wish to consider:
• Water heating. If you are intending to have a wetback it is important
that the wood fire is as close as practically possible to the water storage
cylinder
• Split level homes are best heated when the wood fire is installed on the
lower level, as the heated air will rise to the higher levels
• Building construction is another consideration. Specified clearances
from walls, curtains etc must be maintained and you need to ensure
no structural beams or internal gutters etc are directly above your
preferred site. If you have a two storey dwelling you need to consider
the second storey to ensure you don’t have the flue directly outside a
second storey window.
Getting to know your Metro wood fire
Operating your Metro fire is simple and you will quickly learn how to get the
best from it. First take a minute to familiarise yourself with your new Metro.
•
Raise the door handle anticlockwise until the latch releases, then
slowly pull the door open. Load fuel and then close the door ensuring
the latch is secure. Never operate with the door open or not latched
securely, except on start up – see below.
Generally, you can install your Metro in your home anywhere that suits you;
Pioneer offer various fan systems to transfer heat to other sections of the
home that are not heated sufficiently. It is necessary if using a fan system
that the Metro you have purchased has sufficient output to heat the total
area you wish to heat. Your Metro retailer or installer will be able to advise if
you are uncertain.
• There is a single air control making your Metro fire easy to adjust. This
control moves from left to right, which is ‘low to high’.
Operating your Metro wood fire
If your Metro has only been installed within the past few days, the fire
cement seal at the base of the flue will not be fully cured. To ensure the
cement sets without blistering it is recommended you burn 2-3 sheets of
loosely crumpled newspaper at a time, approximately once every hour over
a 6-8 hour period.
During the very first fire your Metro will give off an odour and fumes as the
firebox paint cures. Do not be alarmed. Open all windows and externally
opening doors in that room and close any internally opening doors. This
curing process will last for approximately one hour and is likely to happen
this one time.
Start up
Place a quantity of loosely crumpled newspaper on the base of the firebox
until it is approximately half full of paper, or place firelighters on the base
of the firebox. Add dry kindling and move the air control knob fully to the
right, being the ‘full open’ position.
Light the paper at two or three locations across the front of the door
opening and leave the door slightly ajar resting on the latch pin if necessary
for a few minutes while the fire establishes. Once the kindling is burning
Mega Smart Built-In air control
well, open the door and add 2-3 small logs at a time until you have a well-
established fire. Usually this will take approximately 30 minutes, during
which time the air control should be set on “high” and the door should be
closed, except for the initial few minutes and when fuel is being added.
Normal operation
Once the fire is well established, regulate the air control to achieve the
desired burn rate and heat output. As you move the air control to the right,
burn rate, firebox temperature and heat output will increase, if you move
the control to the left they will decrease. Please note:
• Always open the air control fully prior to opening the door, then open
the door slowly. Every time you refuel, leave the air control on ‘high’ for
a minimum of 20-25 minutes
• When loading logs, place them end-on, ‘front to back’; air spaces
should be left between the logs to enable oxygen to get to as much of
the surface of the fuel as possible
• Never use the door to force wood into the firebox, as this is likely to
break the glass.

Cleaning and maintenance for your Metro wood fire
Your Metro fire will give you many years of efficient service with minimal
maintenance if operated correctly using seasoned fuel. Your Metro fire
must be regularly maintained and replacement parts must be authorised
Metro fires parts only.
The Metro Mega Smart Built-In fascia is coated with vitreous enamel.
Vitreous enamel is extremely durable and designed to last the life of the
appliance. As vitreous enamel is glass, a solid or heavy object dropped or
banged against a panel could chip the enamel surface.
All model Metro fires can be cleaned with a soft cloth when the appliance
is not in operation.
Door glass
Providing your fuel is properly seasoned, under normal operating
conditions the air-wash design of the Metro’s firebox will keep the door
glass clear. If the glass requires cleaning you may use either a razor blade
scraper or crumpled wetted newspaper dipped in wood ash rubbed over
the glass.
If your door glass breaks it must be replaced with 5mm thick ceramic glass
which is available from your local Metro retailer.
Door seals
Over time, usually 3-4 years, the door and glass seals will become hard and
cause air to leak into the firebox, causing the appliance to ‘over fire’. Your
Metro retailer stocks replacement woven fibreglass door and glass seals,
which need replacing when they become hard and over worn.
To remove the excess ash your Metro should not be operating.
• Open the door, and using a hearth shovel or similar, empty the excess
ash directly into a steel or non-combustible container.
• If the ash is not disposed of immediately, be careful where you store it,
as the ash can retain heat for many days and become a fire hazard.
• You must leave a bed of ash in the base of the firebox approximately
10mm deep; this insulates the base of the firebox and improves
combustion.
Top baffle
This is a ‘sacrificial’ wear part of the firebox and should be checked
monthly. Usually only the promet (white board) front/underneath section
needs to be replaced when it starts to disintegrate.
Note: Cracks in the promet are not uncommon and have no adverse effect
on the operation of your Metro. These cracks are the result of intense
heat coupled with expansion and contraction. Burning wood which is not
properly seasoned, i.e. 25% moisture content or more, will over time cause
the promet to disintegrate and require replacement.
Front top baffle
Rear top baffle
The door of your Metro is easily removed. Hold it in both hands and lift the
hinge end of the door up and over the top hinge pin, then lower the door
from the bottom hinge pin.
Side bricks
Hair-line cracks are not uncommon and are a result of the intense heat
within the Metro’s firebox, coupled with mechanical damage caused by
accidental impact when fuel is being loaded. However if the side bricks
become cracked to the extent that they start to break up, they must be
replaced.
Door adjustment
Provision is available on both sides of the door for adjustment.
To adjust the hinge end of the door, open the door fully, loosen the top
hinge nut and slightly lift the latch end of the door; you will see the hinge
assembly move back 1-2mm which will usually be sufficient. Retighten,
then repeat by loosening the lower hinge nut, this time applying a slight
downwards pressure onto the door to move the lower hinge assembly back
a similar distance, then retighten.
The door latch is also adjustable, as the latch pin on the right side of the
firebox is fitted through a slot which enables the latch pin to be loosened,
moved back and re-tightened.
Side Brick
To remove and replace your Metro’s top baffle, proceed as follows: -
• Open the Metro’s door fully, reach inside with the palm of your hand
face up and extended, lift the front baffle approximately 20mm, then
lift it forward out through the door opening placing it on a sheet of
newspaper you have placed on the front of the hearth. Now lift the rear
baffle section up off it’s pins and remove out through the door opening.
• To refit the baffles. Proceed in the reverse order and note, the rear
baffle must be fitted so its back-edge is touching the back of the
firebox.
Ash removal
Over a period of time ash will build up in the base of the Metro’s firebox
and require removal. The time this build-up takes depends on the density
and cleanliness of your fuel.
13
Cleaning and maintenance for your Metro wood fire
Flue systems
Should be checked annually, particularly the bottom end of the lower flue
section at its rear lock formed joint. If deterioration is noticed contact your
Metro retailer or installer.
The flue pipe should also be swept a minimum of once a year, or as
required during the winter season. If smoke enters the room when you
open the Metro’s door this usually indicates the flue pipe is becoming
restricted and needs cleaning. The frequency of flue pipe cleans depends
on many factors, with the main variables being:
• The seasoning of the wood. If not properly seasoned you will require
frequent flue pipe cleans.
• The density of the wood. Softwoods generally result in more deposits
building up in the flue pipe.
To clean the flue pipe of your Metro, proceed as follows:-
• Open the Metro’s door fully, reach inside with the palm of your hand
face-up and extended, lift the top baffle approximately 20mm, then
lift it forward out through the door opening, placing it on a sheet of
newspaper you have placed on the front of the floor protector. To
prevent jamming, removal and replacement of the top baffle is best
performed using both hands.
Note: The Mega Smart Built-In features a two piece top baffle.
• Close the door and slide the air control to the left.
• Once on the roof, remove the cowl from the top of flue system and
sweep the flue pipe using a 150mm-diameter flue pipe brush as
detailed in the instructions provided with the fluebrush.
• Once the flue pipe is clear, clean and refit the cowl. Remove the excess
soot which has fallen into the firebox, leaving a layer of ash 10mm
deep on the base of the firebox, then refit the top baffle.
Note: The baffle must be fitted so its rear is touching the back of the
firebox; if uncertain refer to the previous page 12 in the installation section
of this manual, which shows an illustration of the baffle location.
Parts guide for your Metro – Baffle, promet and wetback
Listed below are the parts and product codes for your Metro wood fire. The
promet/baffle should be regularly checked and must always be in place
during the operation of your fire.
Note: Cracks in the promet are not uncommon and have no adverse effect
on the operation of your Metro. These cracks are the result of intense heat
coupled with expansion and contraction and is normal wear & tear.

Troubleshooting your Metro wood fire
If your Metro is installed correctly, your fuel is dry and you operate your
fire correctly, you will find it to be a pleasure to use. Metro’s many years of
experience within the wood heating industry has shown that dissatisfaction
is mainly due to:
• unseasoned fuel
• faulty installation
• operational error
• or a combination of the above 3 points.
Correct operation
Modern day wood fires need to be operated hard and fast, more so than
low and lazy to ensure the firebox and flue pipe runs hot and efficiently. If
the fire and flue pipe is up to temperature it will perform extremely well, the
smoke will draw up the flue pipe with ease, and the fire will produce good
amounts of heat.
If the fire is operated on low a lot of the time, the door glass will run black,
the flue pipe will tend to block up more frequently and the fire will end
up smoking into the room when reloading. It’s better to have a small fire
running hard and fast, rather than a big fire running low and lazy.
The following may be of assistance if you are experiencing any problems
with the operation of your Metro Fire.
Smoke enters the room when the Metro’s door is ajar
(possible reasons and solutions)
Check flue pipe joins
If the flue pipe joins are not sealed correctly, the flue pipe will not draw as well
as it should. The flue pipe join connecting into the flue spigot on top of the
Metro is most critical, if this is not sealed correctly, smoke will enter the room
when the door is ajar. To check this join is sealed correctly, run a match or
lighter flame around the join. If the flame is sucked into the spigot then it is
not sealed correctly. This check needs to be done when the fire is not going.
Ensure you check the rear of the flue pipe/spigot join, as due to the seam in
the flue pipe, this is the most common area for not being sealed correctly.
Ensure the fuel you are using is correctly seasoned
If you are burning unseasoned fuel (wet), the fire will cause nothing but
problems. The Metro won’t deliver much heat, it will be lazy, smoke will
enter the room when the door is ajar, and the door glass will run black.
Unseasoned fuel is the main contributor to excessive creosote deposits
which can be corrosive to your appliance and flue system.
Air turbulence and/or negative air pressure influences around the flue
termination can be caused by too close or overhanging trees or natural/
artificial ridges etc. Address these where possible or look to extend the flue
above the roofline.
Other options may be:
• ‘H’ Cowl, designed purely for downdraft issues, but if you have an ECO
Cowl fitted as standard, you will also need to add another 600mm of
flue pipe to compensate as the H Cowl is shorter in length
• Directional Cowl, designed for high wind areas.
Air control setting
Ensure the air control setting is on high before opening the door to reload,
as this increases the draw up the flue pipe. Open the door slowly.
If your Metro did not smoke, but its starting too and is getting worse:
The flue pipe is in need of a clean. It is recommended that the flue pipe be
cleaned every season, however if you are burning the fire on low a lot, or are
using unseasoned fuel, flue pipe cleans will be required more frequently.
Other issues you may experience
I can smell smoke in the room after a low burn cycle
The smell is creosote that will be seeping through the flue pipe join or
out of the flue spigot onto an external surface, thus creating the smell
in your room. The cause will be either unseasoned fuel, fuel mass too
large, incorrect operation on low burn cycles or a combination. Creosote
is very corrosive and excessive buildups will result in the flue pipe and
potentially the flue spigot and upper burn chamber failing. The formation
of excessive creosote is not an appliance issue, it is a fuel and operational
issue. Failure of flue pipe or firebox due to creosote build up is not covered
under warranty as excessive creosote build up is only possible from either
unseasoned fuel or incorrect operation.
The Metro won’t turn down as much as it did
The door itself may need readjusting, the hinge and latch is slotted and
allows for movement. Loosening the hinge and moving it back a few mm will
make the door seal tighter and stop air leaking into the fire. The door and
glass seals may be in need of replacing, which is generally required every
3-4 years.
Familiarise yourself with the instructions on page 8 before proceeding with
this maintenance.
Flue pipe length is too short
Add more flue pipe as the longer the flue system, the better the draw of
the flue pipe. Please note, if you did not purchase the Metro ECO Flue
System, you will not have the ECO Cowl which increases draw. We highly
recommend the Metro ECO Cowl is fitted as this will increase the draw. If
you already have an ECO Cowl and smoke is still entering the room, please
add another 600mm length of flue pipe.
Downdraft/Turbulence blockage
If you have checked all of the previous factors and the fire is still smoking
into the room, it’s possible there may be a down draft issue. Down draft is
environmental and can be caused by many variables, and it is purely trial
and error to ascertain the cause.
