electrical connection and replace the fan motor and thermostat
if necessary

• A rear cavity vent is required. Please see detail in Diagram 1 opposite

with full cavity vent requirements and installation detailed on page 8 of

this manual

• In New Zealand, the Metro Ultra Insert must be bolted securely to the

base of the chimney cavity to comply with the seismic restraint provisions

of AS/NZS2918

• The Ultra Insert fascia is coated in metallic black high temperature paint

finish. Take care during assembly and when lifting and fitting the fascia

that you do not damage the coating. Any surface damage to the paint

finish fascia can be repaired with the use of Pioneer metallic black high

temperature paint

• DO NOT lift the Ultra Insert fascia with your fingers under the louvre’s

Pre-installation - Firebox cavity

Your Ultra Insert is packaged in two heavy-duty cartons. The Insert firebox

is in a palletised carton, while the fascia and door are packaged together in

a separate clearly labelled carton.

Electrical

A 230v fan is assembled with the firebox and requires a registered

electrician to wire into a 230/240VAC – 50/60Hz power supply.

The fan is controlled automatically by a thermostat, delivering low air

volume very quietly, usually within 10-20 minutes of lighting the fire.

Pre installation - Firebox cavity

Prior to installing your Metro insert firebox into a fireplace cavity, it is

important that specified clearances and other requirements are complied

with as follows:

• The chimney must be swept and checked for cracks and general

overall condition. If repairs are necessary, they must be carried out by

a suitably qualified person

2

• Adjust cavity to minimum dimensions as illustrated in Diagram 1 on

page 3. It is usually necessary to remove fire bricks from the lower

fireplace cavity

• The base of the fireplace cavity on which the Metro Ultra Insert will rest

must be level. If it is not, it should be levelled using mortar

2

• A rear minimum open vent area of 14,400mm

height of 230mm must be cut through the chimney. Please see detail

in Diagram 1 opposite with full cavity vent requirements and installation

detailed on page 8 of this manual

• If a timber or combustible mantelshelf exists above the fireplace

opening, it should be a minimum distance above the top of the Ultra

Insert fascia. If less than the minimum specified, a deflector or heat

shield will be required to be fitted under the mantelshelf or to the top of

the fascia using the relevant detail as set out in AS/NZS 2918. Mantle

clearances are detailed on page 9.

Installation of the Ultra Insert firebox

Ultra Insert firebox installation

1. Packaged loose within the firebox are 3 fire bricks, air slide lever and

knob, Top Panel with insulated side Support Panels, top ceramic fibre

blanket and bolt kit packed with this manual.

2. Position the firebox and cabinet into the prepared masonry cavity,

ensuring cabinet is level and square. The front base of the cabinet

should extend approximately 50mm forward of the masonry surround

and have a minimum of 610mm height opening at the front to allow

space for soft ceramic fibre blanket (not yet fitted).

3. Unscrew the ceramic fibre board from the Top Panel (packaged

in front of the firebox) so the side insulated support panels can be

riveted in place as illustrated. Leave the cellotape in place that holds

the ceramic fibre then re-attach the ceramic fibre board again. Slide

the top panel assembly in over the cabinet sides and under the rear

blanket while ensuring the panel engages into the slot provided at

the top of the cabinet. Temporarily screw the top panel in place as

illustrated.

4. Place the four speed clips over the large diameter mounting holes

in the return folds at the front of the cabinet (fascia mount points).

Attach the fascia ensuring to lift it over the Top Panel as you position

it prior to pressing it into place. Attach the 4x fascia mounting screws

(8g x 19mm) while positioning the fascia evenly around the door. With

the fascia firmly secure, push the fire and fascia fully into position.

Once the Metro is fully installed it is best to wait 24 hours for the flue seal

cement to dry. Alternatively, it is recommended you burn a couple of sheets

of loosely crumpled newspaper at 30 minute intervals over a four-hour

period before operating fire normally.

5. If you are satisfied with the position of the cabinet and fascia, while

confident flue access is acceptable or if any additional telescopic

offset that may be required to connect the flue has been assessed.

Then remove the fascia to secure suitable masonry anchors to comply

with the seismic restraint provisions of AS/NZS2918.

6. Remove the upper Top Panel from the cabinet and following the flue

system installation instructions detailed on page 6, proceed and fit

the flue with All JOINTS SEALED and riveted with a minimum of three

stainless steel or monel rivets on each joint.

7. With Pioneer fire cement applied around the perimeter of 150mm

flue, approximately 20mm below the flue swage, firmly force into the

flue spigot. Using a 4mm drill bit, drill though the flue via the seismic

restraint hole in the flue spigot and secure the flue with the 14g Tek

screw supplied.

8. Before fitting the Top Panel, first place the Ceramic Blanket overlay

provided (610 x 340) over both the Top Panel and rear cabinet

insulation as the Top Panel is positioned, then fix in place with four 8g

x 10mm screws.

9. Provisions for wiring the fan unit need to be undertaken by a

registered electrician with relevant testing to gain electrical compliance

while leaving the switch in the ‘on position’ once completed.

10. With electrical connected, fully open the door handle anti-clockwise,

so the fascia can be refitted while ensuring the fascia is evenly

positioned around the door frame. Secure the four mounting screws

and check door operation and required seal to firebox.

WARNING! Important Information

4. Rotate the door handle fully anti-clockwise before placement of the

fascia. The inner fascia slips snugly into the cabinet with the Top Rail

of the fascia resting onto the Top Panel of the cabinet.

ALWAYS ELECTRICALLY ISOLATE THE FAN WHEN IT IS
NECESSARY TO REMOVE THE FASCIA FROM THE FIRE

Take care not to lift the fascia by the louvres as they can bend.

1. If you haven’t already fitted the door, do so now ensuring the spacer

washer is placed on top of the hinge pin as indicated in Diagram 2

(Inset A)

2. Ensure the four speed clips are positioned over the large diameter

mounting holes in the return folds at the front of the cabinet (fascia

mount points). Attach the fascia ensuring to lift it over the Top Panel

as you position it prior to pressing it into place. Attach the 4x fascia

mounting screws (8g x 19mm) while positioning the fascia evenly

around the door.

3. At this time ensure the fan unit is positioned with the grommets over

the location bolts at each end of the fan tray. Check the thermostat

plug is attached with wiring and lead kept away from the firebox. Any

excess lead must be shortened or positioned to the outside of heat

shields or cabinet. Ensure the fan rotates freely.

5. The fascia should be evenly spaced around the door frame and sit

evenly against the masonry surround 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).

6. Open the door and remove the two nuts and air slide guide washers

to enable placement of the air slide. The air slide feeds ‘lever end’ first

behind the fascia and through the lever slot. Fit the guide washers

and nuts and ensure the slide moves freely with the lever resting

gently on the fascia slot.

7. Fit the 4x fascia mounting screws (8g x 19mm) into the speed clip

fixings earlier attached while positioning the fascia evenly around the

door. The air control knob can now be fitted.

WARNING! Important Information

• A registered electrician is required to replace the fan motor
and thermostat if necessary

• Use authorised Metro replacement parts only. The use of
unauthorised parts will void the warranty and compliance

• The appliance is not to be used by persons (including children)
with reduced physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they have been given
supervision or instruction.

• If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard.

• Ensure the power supply is electrically isolated if the fan or
thermostat requires replacement. (ELECTRICIAN ONLY)

• The fan is a permanent fixture and can only be replaced by a suitably

registered electrician.

• The fan must always be connected to a 230VAC power supply when the

fire is used. The 15 watt fan will operate once the thermostat heats to

40°C. This can take between 10 - 20 minutes. If the thermostat requires

replacement you will need to remove the fan to access.

To replace the fan / thermostat (Electrician only)

Firebox parts and components - Bricks, baffle and airtube

Side and rear firebricks placement or removal

• Raise the rear corner of the side brick so the brick can move back

sufficiently to allow the front edge to swing in towards the centre of the

firebox while moving the brick free of the rear support bracket

• The rear brick can be manoeuvred out from the support brackets at any

time, or raised up if the baffle has been removed

Air Tube removal

• The Air Tube must be removed to allow removal of the baffle. The Air

Tube retaining clip is easier accessed if the front of the baffle is raised by

resting a spacer on top of the pin to see the tube slip ring and locking pin.

Once the locking pin and slip ring is removed, the Air Tube slides to the

right to release the left side allowing the tube to be fully removed. When

refitting the airtube the left side has to index over the bolt head locator so

the air jets face in a forward/down direction.

Upper baffle removal

The Air Tube must be removed to enable baffle removal. Before lifting out the

baffle note the position of bolt heads and other obstructions that the baffle

needs to clear on removal.

Side brick - Step 1

Raise the rear corner of the side brick
so the brick can move back to provide
clearance at the front of the brick.

Side brick - Step 2

Swing the front edge of the brick into
the centre of the firebox to get the
brick free of the rear support bracket.

• Lift the rear of the baffle 20mm to clear rear support pins and slip forward

20mm while also supporting the front of the baffle so it does not drop

down, then lower the rear of baffle vertically down while guiding the front

of the baffle behind the front baffle pins. Tilt the vertical baffle forward

and extract at 45 degrees while clearing hinge bolts and latch bolts.

• If replacing sacrificial ‘Promet’ boards on the baffle, finger tighten the

bolts then using a spanner tighten nuts a further half turn. Over tightening

will cause the linings to crack during expansion/contraction.

Check to ensure the top baffle is in its correct position in the top chamber of

the firebox. It should be resting on four support lugs (two on each side of the

firebox). The baffle must be hard back against the rear wall of the firebox.

Rear brick - Step 1

Raise the square end of the rear brick
so the brick can move back to provide
clearance for the front edge.

Rear brick - Step 2

Swing the front edge of the brick into
the firebox to get the brick free of the
rear support bracket

Ultra Insert Flue Kit Installation Instructions & Component Checklist

Please read these instructions fully prior to installation of the Ultra Insert flue

kit and familiarise yourself with all the various components illustrated left and

(A)

listed below.

(B)

(C)

(D)

(E)

(F)

Note: Rivets, fire cement, chimney cap/flashing plate and masonry vent cover

are not included as they are supplied by the installer/home owner. Pioneer

manufacture a stainless steel masonry vent cover kit to complete installation.

Ultra Insert Flue Kit Components

(A) 1 x Stainless steel weather butterfly

(B) 1 x Stainless steel ECO Cowl top

(C) 1 x 420mm x 240mm diameter stainless steel ECO Cowl housing

(D) 1 x 480mm long stainless steel flue pipe extension with flashing cone

(E) 2 x 1200mm x 150mm diameter stainless steel flue pipe

(F) 1 x 600mm x 250mm diameter galvanised outer casing

(G) 1 x 1300mm x 150mm diameter stainless steel flue pipe (pre-fitted liner)

The Ultra Insert flue kit features a custom 1300mm length of 150mm diameter

flue pipe (G) with a pre-fitted stainless steel flue liner.

This section of lined flue must be fitted as close as possible to the Ultra Insert

firebox. If possible connect directly to the Ultra Insert flue spigot, but if it is

necessary to use a telescopic offset, then the section of lined flue must fit

directly above this component.

This flue kit has been manufactured and complies with AS/NZS2918:2001. To

ensure a safe and efficient installation, this flue kit must be installed as detailed

below by either a registered installer, or someone competent in installing solid

fuel appliances.

1. Check the masonry chimney for structural soundness and make any

repairs that are necessary.

(G)

6

Note: Most councils require the masonry chimney to be inspected prior to

installation. The masonry chimney cavity must also be swept prior to installation.

2. Once the fireplace insert has been installed correctly to the manufacturers

instructions, look directly down the chimney to ensure the firebox flue

spigot is in line with the masonry chimney. (A torch will be required).

3. If you cannot see the flue spigot, a flue pipe offset will be required. If so,

install the flue pipe offset so the top of it can be clearly seen from the top of

the masonry chimney.

Ultra Insert Flue Kit Installation Instructions

4. If an offset is required, an adjustable telescopic type is recommended.

Measure the amount of offset required and adjust the telescopic offset

to suit, after smearing an adequate amount of Pioneer fire cement onto

the slip section of the offset to ensure a good seal, then rivet the offset

in three locations around its circumference. (If the offset is used in its

fully compressed form, it will be necessary to modify the end of the

female slip section otherwise it will restrict the internal diameter) Apply a

liberal amount of Pioneer fire cement into the flue outlet of the fireplace

insert, and fit the lower crimped end of the offset into position inside the

flue outlet, and bolt into position.

Note: In some installations where it is not possible to fit offsets or rigid

flue pipe due to the shape of the masonry chimney cavity, ‘Flexi flue’

may be used.

5. Secure the flue pipes together and ensure the flue seams are staggered.

Flue pipe joints must be fully compressed with a considerable amount

of fire cement to ensure a good seal, and then riveted together at three

even points around the flue join. Prior to installing the assembled flue

pipe into the masonry chimney cavity, take careful note to ensure there

are no overhead power lines in close proximity.

6. Lower the flue pipe into the masonry chimney, with the crimped end

fitting into the fireplace insert flue outlet/offset, and securely attach

with three rivets (offset/bend must be riveted to the flue pipe). For

installations where extra lengths of flue pipe are required, or when the

weather is poor, it will be easier to assemble the flue pipe lengths as

they are lowered into the masonry chimney.

7. Secure the outer casing to the masonry chimney with suitable fasteners.

A masonry chimney flashing plate will be required to weatherproof/seal

the masonry chimney top. Note: The top of the outer casing must be
‘level’ (+ or -10mm) with the top of the 150mm stainless steel flue pipe.

8. Assemble the ECO Cowl as follows;

- Take the stainless steel weather butterfly (A) so the angled sections are

facing up.

With both arms and angled sections of the stainless 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.

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.

9. Making your way back onto the roof, fit the 480mm long flue pipe

extension/flashing cone (D), with the flashing cone at the bottom. Fit

the 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 casing slip section. Drill through the

pre-punched hole in all three brackets into the outer casing slip and

secure with rivets.

10. Taking the ‘removable section of the ECO Cowl’ assembled in section (8)

above, 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 therefore enables easy removal for future flue cleaning.

Minimum Heights for all Metro Flue Systems In compliance with AS/NZS2918:2001

The Metro ECO Flue Systems comply with AS/NZS2918:2001 and its

4.6 metre height requirement (4.6 metre minimum from the top of the

floor protector to the top of the flue pipe). However as external structures

and the proximity of other buildings will differ for every installation, some

situations will require additional flue height to comply with the standard.

Congratulations on the purchase of your Metro wood fire

This 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.

Your Ultra Insert must only be installed with a Metro Ultra Insert Flue kit.

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.

• It is critical that the fire is operated with the fan switched on.

Please note, the above 4 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 5 year firebox warranty.

Parts guide for your Metro – Promet, baffles and wetback options

Your Metro wood fire must be regularly maintained and we recommend

it is also serviced annually. If a wood fire is not regularly maintained and

serviced, the life span will be reduced.

If your Metro wood fire has been neglected by not being regularly maintained

and serviced, with authorised Metro parts replaced as required, or neglected

through misuse, any warranty claim may be declined.

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.

The baffle should be resting on four support

lugs (two on each side of the firebox). It must be hard back against the rear

of the firebox with the ‘promet lining’ (white board) or return front steel edge

of the baffle facing forward.

• Ultra Insert Door Glass 500-0150

• Ultra Insert Convection Tube 500-1506

Type of promet required / Type of steel baffle(s) required

Hairline cracks in the promet lining are not uncommon and will have no

adverse effect on the operation and performance of your Metro wood fire.

These cracks are the result of intense heat coupled with expansion and

contraction and is normal wear and tear.

If the promet lining starts to break up and pieces fall into the firebox it must

be replaced.

Note: Impact damage when loading wood and burning wood which is not

properly seasoned, i.e. 25% moisture content or more, will cause the promet

to disintegrate and require replacement. Always burn dry well seasoned

wood and take care when loading wood into the firebox.

Operating 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 anti-clockwise until the latch releases, and then

slowly pull the door open. You will note that if you let the door go before

it is at 90° to the appliance, it will fall closed. This is a safety feature

that ensures the door cannot fall open if it is not latched securely. For

the door to remain open, you must open it fully

• 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’.

The Metro Ultra Insert is the world’s first conventional insert fire that meets

the specification of ECAN’s Ultra Low Emission standards and discharges

incredibly low emission particulate even during the ignition light up phase.

If your Metro has only been installed within the last day, 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, at 30 minute intervals over a 4 hour period.

Fuel

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.

The moisture content must be under 25%. It is best to allow a minimum

of 12 months drying time for soft woods and at least double this for hard

woods with good air flow required through the stack.

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.

Burning properly seasoned (dry) fuel will result in;

• Less ash buildup

• Less emission into the environment

• Less creosote that can cause a host of issues

• Maintain a clean flue system

• Extend the life of the sacrificial components in your fire

Fan

The fan must always be switched on. The fan will start when the thermostat

reaches 40ºC in approximately 10-20 minutes from initial lighting delivering

low air volume very quietly.

It is always recommended to burn well dried fuel that has good air flow to

ensure the timber has dried right through to the core. Seasoned timber will

only dry over one summer subject to it’s size and if it is covered from rain

but also allowing plentiful air to pass through the stack for drying.

Operating your Metro wood fire - continued

The Metro Ultra Insert is the world’s first conventional Insert wood fire

that meets the specification of ECan’s Ultra Low Emission standards and

discharges incredibly low emission particulate even during the ignition light

up phase.

You can greatly assist in minimising emission discharge by following the

guide below on how to help reduce emission while also helping yourself

with this ideal lighting technique. This ‘upside-down method’ is particularly

time saving to light as two minutes after ignition the door can be fully closed

while the fire generates a good ember bed without constant ongoing effort

of loading fuel to establish the ember bed. The less time the fire door is

opened, the quicker the fire heats and forms an ember bed of hot coals to

enable the addition of further fuel. Fuel positioning is predominantly in a

front to back orientation to promote air flow within the combustion chamber.

The specified emission results were achieved by following the desc

method below using dry fuel with less than 25% moisture content.

Cold start with air control fully open:

• Place 3 to 4 medium pieces of wood as shown (total weight 1.2kg)

• Cross stack kindling on top of the lower stack (kindling weight 1kg)

• Place fire lighters, one each side of the load near the top

ribed

Start up load

• Light the fire lighters and partially close the door, resting the door

spindle on the latch

• After 2 minutes with the kindling well alight, fully close the door.

Intermediate load with air control fully open:

• Approximately 40 minutes after lighting, once remaining fuel has

formed hot coals that crumble on reload, place the intermediate load

of firewood

• Place 3 to 4 pieces (approximately 1.2kg) across the ember bed

as shown. Maintain gaps between each piece but if one layer is too

condensed, cross stack a piece on top.

Main loads:

• Approximately 40 minutes after last loading, once remaining fuel has

formed hot coals that crumble on reload place your normal sized

firewood (Approximately 2kg). 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, firebox temperature and heat output

will increase, if you move the control to the left they will decrease

• 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’ to

re-establish the fire

Intermediate load

Main load

• 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.

Reloading:

When reloading, always ensure firewood is placed onto an established

ember bed. If the ember bed is low, open the air control to maximum and

load smaller timber pieces to re-establish the ember bed.

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 front panelling of your Metro insert fires fascia is coated with high

temperature paint finish which will require periodic repainting to keep

it looking its best. The fascia can be cleaned with a soft cloth when the

Metro is not operating. This coating is susceptible to scratching, so care

is required. Fascias coated with high temperature paint can be easily

resprayed using Pioneer metallic black paint.

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.

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.

• 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 cause the

promet to disintegrate at a faster rate and require replacement sooner.

Airtube

This is a wear part of the firebox and should be checked monthly. Replace

when worn out for optimum performance. Removal and replacement of the

airtube is detailed on page 5.

Flue systems

Your Metro Ultra Insert has a special flue incorporating a lower liner which is

required at the base of the flue.

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.

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.

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.

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.

To clean the flue pipe of your Metro, proceed as follows:-

• Remove the airtube and top baffle as detailed on page 5. Place these

parts 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.

• 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 and airtube.

Note: The baffle must be fitted so its rear is touching the back of the firebox;

if uncertain refer to page 5 in the Upper Baffle section in this manual.

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)

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.

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.

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.

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.

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 13 before proceeding with

this maintenance.
