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.
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
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.
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.
