SAFETY
Safety is the most important consideration when using and installing your stove. If not
installed and used correctly, a house fire could result. Installation must comply with
relevant national and local Building Regulations and fire safety standards.
IN THE EVENT OF A CHIMNEY FIRE, EVACUATE THE PROPERTY AND CALL THE
EMERGENCY SERVICES.
Your stove will be heavy, and care needs to be taken when lifting - 2 people will normally be
required to lift.
UNPACKING
Your stove will have several of its components stored inside the stove itself for
transportation.Your stove is fully constructed and the only component that needs attaching
is the flue collar. This will simply need attaching with the provided bolts on the top or rear of
the fire. If you are choosing to use the top flue outlet, ensure the rear flue outlet is blanked
off with the blanking plate and not left open. The same applies if you are attaching the flue
collar to the rear. When the collar is attached ensure you remove the free oven glove and
any small accessories that may be tucked away under the grate before lighting the stove for
the first time. Your new stove is lined with vermiculite fireproof bricks that are sand like in
colour. These are not part of the packaging and need to remain in the stove at all times.
INSTALLATION
Installation of your stove must comply with relevant local and national Building Regulations
and fire safety standards. We would always suggest using a qualified installer to carry out

the installation of this product. The British recognised standard for solid fuel installations is
HETAS. You can find a HETAS qualified installer in your area by going to the HETAS website
–www.hetas.co.uk. If you are self-installing, the stove must be signed off by the local
authority.

Distances to combustible materials:

Maximum hearth temperature:
Directly under the stove – 82 Celsius
This stove is suitable for a 12mm hearth. For example, a 12mm glass hearth can sit directly
onto a wooden floor and this unit can be sat on top of that.
Your stove will require a constant air supply and should not be used at the same time or in
the same room/space as extractor fans or any device which may draw air supply away from
the stove. The stove should be installed on a level floor with adequate load bearing capacity.
The stove does include adjustable feet for levelling.
Normally for most houses in the UK, no extra ventilation is required when installing a stove
rated at 5kW or less.

Note: The requirements regarding ventilation have been updated in the most recent
version of the Building Regulations and are now based on the air permeability of the house.
The stove is NOT suitable for installation in a shared flue system.
The flue pipe must be fitted INSIDE the flue spigot and sealed with a generous amount of
Fire Cement. A 5” flexible flue liner or twin walled chimney system can be used with this unit,
as it has passed the DEFRA testing. Access should be provided for cleaning the flue to
ensure that the passageways for exhaust gases remain free from obstruction.
The Ottawa 5 ECO is a woodburning only unit and does not require or include a grate and
ash pan. Wood burns best on the base with air flowing over the top of it. An additional grate
would increase the amount of air flowing under the fire and drastically reduce the efficiency.
When cleaning the stove out, all you need to do is take a few scoops of ash off the top and
leave the rest in the stove.
OPERATING INSTRUCTIONS
Regulations
All National and local regulations, including those referring to National and European
standards, need to be complied with when installing the stove.
The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authorities may declare the whole or part of the district of the
authority to be a smoke control area. It is an offence to emit smoke from a chimney of a
building, from a furnace or from any fixed boiler if located in a designated smoke control
area. It is also an offence to acquire an “unauthorised fuel” for use within a smoke control
area unless it is used in an “exempt” appliance (“exempt” from the controls which generally
apply in the smoke control area).
In England appliances are exempted by publication on a list by the Secretary of State in
accordance with changes made to sections 20 and 21 of the Clean Air Act 1993 by section
15 of the Deregulation Act 2015. Similarly, in Scotland appliances are exempted by
publication on a list by Scottish Ministers under section 50 of the Regulatory Reform
(Scotland) Act 2014. In Northern Ireland appliances are exempted by publication on a list
by the Department of Agriculture, Environment and Rural Affairs under Section 16 of the
Environmental Better regulation Act (Northern Ireland) 2016. In Wales appliances are
exempted by regulations made by Welsh Ministers.

The Ottawa 5 ECO has been deemed as suitable for use in smoke control areas when
burning seasoned wood logs. The appliance has two factory fitted stops that will need to
remain in place if you wish to keep the stove compliant and legal to use in smoke free zones
or with a 5” flue system or liner.
The first stop is fitted on the airwash vent and prevents it from being fully closed off as
shown below:
