If your Metro is installed correctly, your fuel is dry and you
operate your re correctly, you will nd 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
tted 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 re 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.
Solutions may be:
• ‘H’ Cowl, designed purely for downdraft issues, but if you
have an ECO Cowl tted 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 setting 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 res need to be operated hard and fast,
more so than low and lazy to ensure the rebox and ue
pipe runs hot and efciently. 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 re 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 re will end up smoking into the room when reloading.
It’s better to have a small re running hard and fast, rather than
a big re 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 is noisy as it heats up and cools down:
There will always be some expansion and contraction noise
as the Metro heats and cools. This can usually be reduced by
loosening three nuts at the rear of the appliance. To remedy,
locate the 25mm deep cavity at the rear of your Metro between
the ‘rear panel’ and the ‘inner rear heat shield’. You will see a
6mm nut and two 6mm bolt heads in this cavity. Using a 10mm
ring or open ended spanner, loosen all three so they are nger
tight only.
On all non-DV model Metro’s the air channel that allows the
combustion air to enter the re is tted to the top underneath of
the door opening. It is tted with two M6 bolts. Slightly loosen both
of these bolts. Note: This does not apply to the ECO DV models.
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 re. 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 9 before
proceeding with this maintenance.
