Cleaning and maintenance for your Metro wood fire
Metro fascia
The front panelling of your Metro ECO Smart Insert will be coated
with one of two coating systems, which can be cleaned with a
damp cloth when the Metro is not operating. The two alternative
coating systems used on Metro ECO Smart fascias are: -
• Vitreous enamel which 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.
• High temperature paint finish which will require periodic
repainting to keep it looking its best. This coating is not
as durable as vitreous enamel and is susceptible to
scratching, so care is required. Fascias coated with high
temperature paint can be easily resprayed using Pioneer
metallic black paint.
• 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 firebox
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 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.

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.
• 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
Your Metro ECO Smart Insert has a secondary burn chamber
which enables it to operate at very high efficiency's. This
secondary burn chamber is created by the top baffle which is
illustrated on the reverse side of this manual.
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.
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 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 hearth. Please Note: -
• Your Metro ECO Smart Insert has a two part baffle as
illustrated on page 3. The rear baffle section also lifts "up
and out" the same as the front baffle.
• To refit the top baffle. Proceed in the reverse order and
note, the baffle must be fitted so its rear is touching the
back of the firebox.
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.
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:
