• Pay particular attention to making sure the oor where the
re will sit is level and at as any discrepancies will make

it difficult to slide the fire into place and to 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.

• Be sure to maintain a minimum air gap to combustible

material inside the cavity as set out as follows:

Top Sides Rear

Air Gap 30mm 27mm 50mm

• Remove from within the rebox the plastic bag containing

the component kit, two firebricks wrapped in cardboard

and the top bafe assembly.

• Position the ECO Mega Smart Built-In into the wall opening
you have created (Diagram 1), slide the cabinet into the

cavity until the front edge of the ECO Mega Smart Built-In
cabinet is 3-4mm behind the front face of the wall lining

(Diagram 3).

Note: if you intend constructing a brick fascia in front of the wall
lining then the front edge of the ECO Mega Smart Built-In cabinet
should be 3-4mm behind the front face of the bricks.

• Check the ECO Mega Smart Built-In is central by ensuring

the clearance between each side of the cabinet and the
sides of the opening are equal.

• Secure the ECO Mega Smart Built-In to the oor through the

two restraint holes provided in each corner at the front of
the cabinet. Masonry anchors are required for a concrete

oor and wood screws for a timber or particle board oor.

Note: this must be secured rigidly to meet the seismic restraint
requirements of AS/NZS2918:2001

• Using a 10mm spanner, remove the two bolts holding the

air slide spacers which are located at the top, front of the

rebox, ensuring the control arm of the air slide is located
on the right side of the rebox. Attach the air slide to the
rebox using the two bolts and spacers.

• Position the 200mm/250mm diameter “liner spigot” into

the top of the cabinet centralising it with the centre of the

ue spigot. Secure the “liner spigot” into position using the

twelve self tapping screws supplied.

• Unwrap the two rebricks from the cardboard wrapper and
t the side bricks to each side of the rebox.

Stage 5 – Fitting the ECO Mega Smart Built-In fascia

On a  at surface (a  oor) 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  rebox as follows;

• With the door in a 45 degrees open position, allow the lower
hinge pin on the bottom left hand side of the  rebox to pass

into the hole provided in the bottom of the door frame.

• 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.

• Take the door handle from the plastic bag and screw it onto

the door spindle by turning it clockwise.

• Remove the four speed clips from the plastic bag and  t

them to the holes provided in the four tabs located in the
front of the cabinet.

• 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  re box insert door

and secure the four screws.

Note: If there is to be a timber or combustible mantelshelf above
the Built-In, it shall be a minimum of 500mm above the top of the
ECO Mega Smart Built-In fascia. If less than the above minimum
specifi ed dimension, a defl ector will be required under the
mantelshelf in accordance with AS/NZS2918:2001.

The Metro ECO Mega Smart Built-In requires an insulating  oor

protector, minimum requirement is 18mm thick Promina board
or equivalent, fi nished with a non combustible tile or similar.

This  oor 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 non-combustible point of the Floor Protector.

It is recommended a “Metro ECO Built-In Flue System” be used

with the installation of your Metro ECO Mega Smart Built­In. The Metro ECO Built-In Flue System incorporates Metro’s

unique vertical discharge cowl which improves  ue draft and

performance of the Metro ECO Mega Smart Built-In wood fi re.

Stage 6 – Fitting the  ue system

Box Contents:

• 1 x Metro ECO Mega Smart Built-In water heater

• 1 x 70 ml tube of Pioneer  re cement

Installation - This water heater is designed to
bolt externally to the  rebox, it can be  tted
to either side,  tting the water heater is best
performed prior to installing the  re.

1. Remove the Fascia (if  tted) then remove the vertical
angle cover plate located just behind the door hinge

or door latch pin depending on which side you intend
fi tting the water heater to. If fi tting to the hinge side it is
recommended you remove the hinge also to assist with
access clearance.

2. Fold open the side return of the inner wrap so it is parallel
with the outer cabinet, this is to allow room for the water

heater to slide in between the  rebox and the wrap.

3. Remove the 5 x 50mm knock out plates from the 2 inner

wraps and outer cabinet through which the copper pipes

will exit.

4. With a long handled 10mm set spanner reach in between

the inner wrap and the  rebox and loosen the nuts on the

2 rear and 1 front water heater securing Pozi drive screws,
then unscrew from the inside and discard 2 of the 6mm
nuts as the rear screws will thread directly into the water
heater casting.

5. Remove the water heater from it’s box and inspect the

threaded holes making sure the Pozi drive screws removed

from the  rebox will thread in easily.

6. Thoroughly clean the 2 copper pipe ends with a fi le or
emery paper, this will make brazing easier.

7. Smear a liberal amount of Pioneer fi re cement over the

 anged face of the water heater.

8. Holding the water heater by the bottom of the casting and

the 2 x 25mm tubes facing the rear of the  re carefully

position the water heater in between the inner wrap and

the  rebox until the pipes enter the inner wrap then slide

the water heater along until the front Pozi screw lines up
with the slotted hole. Take care to keep the water heater

close to the wrap and away from the  rebox so as to not

wipe the fi re cement off. Position the water heater so the
front screw passes through the slotted hole in the water
heater, fi t a 6mm nut and washer and hand tighten.

9. Pivot the water heater around this bolt to fi t the remaining 2
Pozi drive screws which are threaded into the casting.

10. Fully tighten all Pozi drive screws, you should see fi re
cement oozing out around the edges which will indicate a
good square fi t.

11. Insulate pipes where they exit the outer cabinet as cold air

is being drawn in past this point.

12. Bend the side return back so it folds around the front of
the water heater and refi t the angled cover plate, this is
critical.

13. Braze the required pipe work to the 2 x copper pipes

in accordance with standard wet back installation
requirements and inspect for leaks. Both side bricks must

be  tted inside the  rebox.

14. Ensure all  rebox and wetback installation and operation

manuals are left for the home owner.

Stage 7 – Metro ECO Mega Smart Built In – Water heater fi tting instructions

• A minimum length of 4.0 metres of 150mm diameter
 ue pipe is required. The total length of the 150mm
 ue pipe must be fully encased from top to bottom
with a 200mm diameter inner casing and a 250mm
diameter outer casing.

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  ue blockages and potential product failure.

1. Your Metro wood fi re must be installed correctly. Metro
recommend a competent and suitably qualifi ed 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 fi res 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
qualifi ed in the installation of wood fi res. Your Metro retailer
will be able to arrange professional installation for you.

• During the very  rst  re your Metro will give off an odour
and fumes as the  rebox 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 effi ciently; fi rewood that contains a high

moisture content will result in  ue 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 or more 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  re 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 fi re, causing the appliance to ‘over fi re’.

• It is critical that the  re not be operated with over worn,
faulty or missing bricks, baf e plate, baf e extension
(white board on the baf e plate)

• It is critical that the  re 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  rebox
warranty. A glowing  rebox or lower  uepipe is just one sign

you are over fi ring 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  rebox. Spaces should be lef t between the logs to
enable oxygen to get to as much of the surface of the fuel

as possible.

• A small hot  re loaded frequently is more ef cient than a

large fi re burning on a low setting.

• Your Metro is covered by a full unconditional 12 month
warranty on replacement parts, and a 10 year  rebox

warranty.

• WE HIGHLY RECOMMEND YOU READ THIS ENTIRE
MANUAL AS INCORRECT OPERATION, MISUSE AND/OR
LACK OF MAINTENANCE WILL VOID THE WARRANTY

•

Any modi cation of the appliance that has not been
approved in writing by the testing authority is considered
as breaching AS/NZS 4013 and will void the warranty

• Do not use  ammable liquids or aerosols in the vicinity
of this appliance when it is operating

• Never operate your Metro with the top grill removed

• Do not dry clothes on or near this appliance

• Do not use  ammable liquids or aerosols to start or
rekindle the  re OR store fuel within the Metro’s speci ed
installation clearances

• Never operate your Metro with the door ajar, except on
initial start up

• Open the air control fully before opening the Metro’s door

WARNING! Important Information

• This appliance should be maintained & operated at all
times in accordance with this instruction manual

• This appliance should not be operated with cracked door
glass, over worn, faulty or missing door seals

• Do not use driftwood, treated or unseasoned (wet) fuel,
the use of most types of preservative treated wood as
fuel can be hazardous and will damage your appliance

• Burning unseasoned (wet) fuel or incorrect operation on
extended low burn cycles will cause excessive creosote
to form. Creosote is very corrosive and excessive
buildups will result in the  ue pipe,  ue spigot and upper
burn chamber failing. Failure of the applicance and/
or  ue system due to creosote damage is not covered
under warranty. The formation of such is not an appliance
issue it is a fuel and operational issue

•

This appliance must be regularly maintained and
replacement parts must be authorised Metro parts only

• Do not empty ash into a combustible container

Congratulations on the purchase of your Metro wood fi re

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:

• Split level homes are best heated when the wood re is

installed on the lower level, as the heated air will rise to the
higher levels.

• Building construction is another consideration. Specied

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 ue directly outside a second

storey window.

Where to install a Metro wood fire in your home

Operating your Metro wood 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.

• There is a single air control

making your Metro easy to

adjust. This control moves

from left to right, which is

“low to high”.

Getting to know your Metro wood fire

Operating your Metro wood fire

If your Metro has only been installed within the past few

days, the re cement seal at the base of the ue 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 rebox 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 rebox until it is approximately 50% full of paper, or
place relighters on the base of the rebox. 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 well, open the
door and add 2-3 small logs at a time until you have a well-

established re. 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, rebox 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.

• 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.

• Every time you refuel, leave the air control on “high” for a

minimum of 20-25 minutes.

• Never use the door to force wood into the rebox, as this is

likely to break the glass.

ECO Mega Smart Built-In air control

The front panelling of your Metro ECO Mega Smart Built-In
will be coated with one of t wo coating systems, both can be
cleaned with a damp cloth when the Metro is not operating.
The two coating systems used on the ECO Metro Built-In fascia
are:-

• Vitreous enamel; this is a permanent coating designed to

last the life of the appliance. As vitreous enamel is glass,

if a solid or heavy object is dropped or banged against a

panel it could chip the enamel.

• Silver high temperature aluminised paint.

• Never use abrasive cleaners

• This appliance must be regularly maintained and

replacement parts must be authorised Metro parts only.

Door glass

Providing your fuel is properly seasoned, under normal

operating conditions the air-wash design of the Metro’s rebox

will keep the door glass clear. If the glass requires cleaning
you may use either a razor blade scraper or an oven cleaner.

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 rebox, 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.

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 rebox, 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 rebox is tted through a slot which enables the

latch pin to be loosened, moved back and re-tightened.

Ash removal

Over a period of time ash will build up in the base of the

Metro’s rebox and require removal. The time this build-up

takes depends on the density and cleanliness of your fuel.

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 rebox
approximately 10mm deep; this insulates the base of the
rebox and improves combustion.

Top bafe

This is a ‘sacricial’ wear part of the rebox 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.

To remove and replace your Metro’s top bafe, proceed as

follows: -

• Open the Metro’s door fully, reach inside with the palm
of your hand face up and extended, lift the front bafe
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 bafe

section up off it’s pins and remove out through the door
opening.

• To ret the bafes. Proceed in the reverse order and note,
the rear bafe must be tted so its back-edge is touching
the back of the rebox.

Flue systems

Should be checked annually, particularly the bottom end

of the lower  ue section at its rear lock formed joint. If

deterioration is noticed contact your Metro retailer or installer.

The  ue 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  ue pipe is becoming restricted and needs cleaning. The
frequency of  ue pipe cleans depends on many factors, with

the main variables being:

• The seasoning of the wood. If not properly seasoned you
will require frequent  ue pipe cleans.

• The density of the wood. Softwoods generally result in more
deposits building up in the  ue pipe.

To clean the  ue 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 baf e
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  oor protector.

Note: Some appliances have a two piece top baffl e.

• Close the door and slide the air control to the left.

• Once on the roof, remove the cowl from the top of  ue
system and sweep the  ue pipe using a 150mm-diameter
 ue pipe brush as detailed in the instructions provided with
the  uebrush.

• Once the  ue pipe is clear, clean and re t the cowl.
Remove the excess soot which has fallen into the  rebox,

leaving a layer of ash 10mm deep on the base of the

 rebox, then re t the top baf e.

Note: The baffl e must be fi tted so its rear is touching the back of the
fi rebox; if uncertain refer to previous page 9 in the installation section of
this manual, which shows illustrations of the baffl e location.

Cleaning and maintenance for your Metro wood fi re

Parts guide for your Metro – Baf e, promet and wetback

Listed below are the parts and product codes for your Metro

wood  re. The promet/baf e should be regularly checked and

must always be in place during the operation of your fi re.

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.

Your Metro wood fi re must be regularly maintained and we
recommended it is also serviced annually. If a wood fi re is
not regularly maintained and serviced, the life span will be
reduced. If your Metro wood fi re has been neglected, by not
being regularly maintained and serviced, with authorised Metro
parts replaced as required, your warranty may be declined.

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.

The following may be of assistance if you are experiencing any

of these problems.

SMOKE ENTERS THE ROOM WHEN THE METRO’S
DOOR IS AJAR (Possible reasons and solutions)

Check ue pipe joins:

If the ue pipe joins are not sealed correctly, the ue pipe will
not draw as well as it should. The ue pipe join connecting into
the ue 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
ame around the join. If the ame is sucked into the spigot then

it is not sealed correctly. This check needs to be done when

the re is not going. Ensure you check the rear of the ue pipe/
spigot join, as due to the seam in the ue 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 re 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 ue system.

Flue pipe length is too short :

Add more ue pipe as the longer the ue system, the better the
draw of the ue 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 ue pipe.

Downdraft:

If you have checked all of the above and the fire is still smoking
into the room, it’s possible there may be a down draft issue.
Down draf t is environmental and can be caused by many
variables, and it is purely trial and error to ascertain the cause.
Solutions 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 ue 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 set ting is on high before opening the

door to reload, as this increases the draw up the ue pipe.

Open the door slowly.

If your Metro did not smoke, but its starting too and
is getting worse:

The ue pipe is in need of a clean. It is recommended that the
ue pipe be cleaned every season, however if you are burning
the re on low a lot, or are using unseasoned fuel, ue pipe

cleans will be required more frequently.

Correct operation:

Modern day wood fires need to be operated hard and fast,

more so than low and lazy to ensure the rebox and ue
pipe runs hot and efciently. If the re and ue pipe is up to
temperature it will perform extremely well, the smoke will draw
up the ue pipe with ease, and the re 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 ue 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.

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 ue
pipe join or out of the ue 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 ue pipe and potentially
the ue 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 ue pipe or rebox 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 11 before
proceeding with this maintenance.

Metro wood fi res are manufactured in New Zealand, using
the highest quality of materials, workmanship and the latest
manufacturing techniques, which is why we offer a full 10 year

 rebox warranty and 1 year parts warranty for peace of mind.

METRO WARRANTY
(NZ Consumer laws apply to this warranty)

Pioneer Manufacturing Limited (Pioneer) warrants the steel
 rebox against defective materials and workmanship which

would render it unfi t for normal domestic use, from the date of
purchase by the original consumer, for a period of 10 years.

Components including panel coating, door retainers, door

seals, glass, trim, baf e & bricks are warranted for a period of

1 year from the date of original purchase for normal domestic
use against defective materials and workmanship.

All associated accessories including, but not limited to, fans,

 ue systems,  ue shields, wetbacks, tool sets, ash pots etc, are

covered by a 1 year warranty against defective materials and
workmanship.

It is recommended, but not a condition of this warrant y, that a
full service/inspection of the Metro wood fi re be carried out at
the end of each winter season.

Warranty Conditions:

• The Metro wood  re must be installed, operated and

maintained strictly in accordance with the building code
and this installation and operation manual.

• The Metro wood  re must be installed and used in a

domestic application.

• This warranty covers appliance like for like replacement or
repair at the manufacturer’s discretion but excludes freight,

travel, installation, labour and/or any other associated costs.
