Wood fires are usually installed in the main living area, which
is the section of the home that is usually kept the warmest,
being the area in the home most frequently occupied.
However, before deciding on the best location for your Metro
wood fire you may wish to consider:
• Water heating. If you are intending to have a wetback it
is important that the wood fire is as close as practically
possible to the water storage cylinder.
• Split level homes are best heated when the wood fire is
installed on the lower level, as the heated air will rise to the
higher levels.
• Building construction is another consideration. Specified
clearances from walls, curtains etc must be maintained
and you need to ensure no structural beams or internal
gutters etc are directly above your preferred site. If you
have a two storey dwelling you need to consider the
second storey to ensure you don’t have the flue directly
outside a second storey window.
Generally, you can install your Metro in your home anywhere
that suits you; Pioneer offer various fan systems to transfer
heat to sections of the home that are not heated sufficiently.
It is necessary if using a fan system that the Metro you have
purchased has sufficient output to heat the total area you wish
to heat. your Metro retailer or installer will be able to advise if
you are uncertain.
Where to install a Metro wood fire in your home
Optional wetbacks and boilers
Water heating is another key feature of your Metro wood
fire; all models can be fitted with the optional 3kW or 4kW
wetback, which are designed to give maximum output with
minimal effect on the operation of the fire. Only the Pioneer
cast jacket wetback system as illustrated on the right should
be fitted to your Metro; alternative wetbacks will void the
Metro’s emission approvals and may seriously affect the
performance of the appliance and void its warranty.
Note: Wetback and Boiler systems are not suitable for use in locations
where the water supply has lime content. Lime build up inside the coil will
eventually block the coil causing the wetback to fail.
Cost Savings
Wetbacks can enable substantial power savings, dependent
on the climate in the area in which you live. If you live in a
cold climate you are likely to use your Metro for many months
of the year, in which case a Pioneer wetback will reduce or
even eliminate your water heating costs over those months.
If however you live in a warmer climate and use your Metro
for only a few hours a day over the colder months, electricity
savings will be considerably less.
3kW or 4kW
The 3kW wetback is usually adequate for most homes;
however, if your hot water use is considerable the 4kW would
be preferable. Other considerations are:
Distance from the Metro to the storage cylinder will affect the
amount of hot water produced. If it is more than 2 metres
away the 4kW is usually preferable.
your climate and the manner in which you will “fire” your Metro
are the most relevant factors in choosing the correct output
wetback. If you are in a moderate climate or have a modern
well-insulated home you are likely to be running your Metro on
lower output settings, in which case the 4kW should be used.
If however you live in a cold climate, or have an older, cold or
large home you are more likely to be “firing” your Metro on a
higher burn rate, in which case the 3kW would be better suited.
Water Pressure
A common misconception is that you must have a low-
pressure system to have a wetback; this is not true. you
must have a “vented” system and high-pressure cylinders
are usually not vented. However you can install an “indirect”
cylinder which contains a secondary coil inside the storage
cylinder, enabling you to have a wetback while retaining a
high-pressure system.
Boiler Options
The larger Metro Mega Rad and Metro Mega Ped are available
with a retrofit-able 7kw boiler option as detailed on page 6 on
the reverse side of this manual, and is designed for connection
to a hydronic system.
