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.
DO NOT operate your fire continuously with a high ash or ember bed as
you can damage the firebox rear wall components or increase the likelihood
of necessary maintenance.
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 and fall into the firebox.
To remove and replace your Metro’s top baffle, proceed as follows: -
• Fully open the Metro’s door and remove the side firebricks carefully.
This will give you maximum firebox width to easily remove the baffle
• Reach inside with the palms of your hand face up and extended and
lift the top baffle up vertically towards the ceiling of the firebox. You can
then pull the baffle assembly forward towards the front of the firebox.
This will allow you to then lower the rear of the baffle past the lug
supports and lift it out through the door opening. Place it onto a sheet
of newspaper or similar to protect the floor protector/coverings
•
Your Metro Insert fire has a two piece baffle as illustrated on page 4. The
rear baffle section also lifts ‘up and out’ the same as the front baffle.
• If your Metro Insert fire is fitted with an internal wetback, to remove
the baffle you will need to remove the fire brick from the opposite side
of the firebox. Then lift the baffle slightly and slide it forward 30mm,
allowing the rear edge of the baffle to drop down in front of the rear
support lugs on the side of the firebox you have just removed the brick
from. The baffle can then be easily removed through the door opening.
• 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.
Circulating fan (Trend Insert only)
In all clean air zones, the Metro Trend Insert must be fitted with
Metro’s ECO Insert fan, This is a single speed, permanently wired and
thermostatically controlled device which runs continuously once the firebox
reaches operating temperature. This fan is designed to run continually for
many years without service, but should be checked monthly to ensure it is
operating. If you are in any doubt regarding the fans operation, refer to your
Metro retailer or a registered electrician immediately.
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: Some appliances have 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 page 3 in the installation section at the front of
this manual, which shows illustrations of the baffle location.
Wetback blanking plates
Metro Insert models can be fitted with a wetback and will feature wetback
blanking plates in the side walls of the firebox. These plates ‘seal’ the
wetback connection holes and are only removed if you choose to fit a
wetback to your fire.
NO WETBACK FITTED
The wetback blanking plates should be checked annually, as any corrosion
or deterioration can allow air to leak into the firebox at these points causing
the appliance to ‘over fire’ and stress firebox integrity.
If deterioration is noticed during regular servicing and maintenance, please
contact your Metro retailer or installer to have these blanking plates and
sealing compound replaced. Failure to act on this may impact on warranty.
WETBACK FITTED
Wetback connection holes are sealed by your installer during wetback
installation. The connection holes should be checked annually to ensure
the seal remains intact, as any deterioration can allow air to leak into the
firebox causing the appliance to ‘over fire’ and stress firebox integrity.
If deterioration is noticed during regular servicing and maintenance, please
contact your Metro retailer or service agent. Failure to act on this may
impact on warranty.
