OPERATING INSTRUCTIONS
3.3 To avoid the build-up of condensation on the door glass it is
advisable to leave the door slightly open as the fire
establishes, and the glass warms.
3.4 As the fire becomes established add larger pieces of wood
and fully close the door. Do not leave the stove with the
door open as this could over-fire the stove and cause
permanent damage.
3.5 As the fire becomes established close the Primary air
control and control the burn rate using the Airwash control
only.
3.6 To burn wood efficiently it is best to allow a bed of ash to
build-up on the grate, and control the combustion using the
Airwash control only.
3.7 Before re-fuelling the stove it is advisable to first rake the
embers evenly over the firebed then open the Airwash
control fully for a few minutes, to establish a glowing bed
before adding new logs.
3.8 Allow the new logs to burn at high output for a few minutes
before adjusting the burn rate with the Airwash control to
the desired setting. It is best to refuel little and often to
maintain clean and efficient burning.
3.9 The ideal control settings to suit the particular installation
and personal preferences will be established by experience
in using the appliance.
3.10 The maximum height of fuel in the Riva stove must not
exceed the secondary air holes in the Stainless Steel fascias.
3.11 It is not recommended to load large amounts of logs and
burn with the Airwash control on low settings for long
periods of time. As this will reduce the effectiveness of the
glass cleaning effect of the airwash. Also this will cause large
a build-up of tars and creosotes in the stove and flue
system.
3.12 We would recommend that the stove is burnt at high
output for at least 30 minutes each day when it is in use.
This will help reduce the build-up of tars and creosotes
within the appliance.
Do not burn painted, impregnated wood or
manufactured board products.
4.1 Open the Airwash control to approximately 50% and
Primary air control fully.
4.2 Place some pieces of firelighter or dry crumpled paper on
the grate and cover with some small pieces of dry kindling
wood. Light the paper or firelighters.
4.3 To avoid the build-up of condensation on the door glass it is
advisable to leave the door slightly open as the fire
establishes, and the glass warms.
4.4 As the fire becomes established add pieces of solid fuel and
fully close the door. Do not leave the stove with the door
open as this could over-fire the stove and cause
permanent damage.
4.5 As the fire becomes established reduce the Airwash air
control to approximately 25% and control the burn rate
using the Primary air control only.
4.6 Before re-fuelling the appliance it is advisable to first de-ash
the firebed, using the riddling grate system, operated by
using removable handle to pull the riddling knob in and
out. This causes the ash to fall down into the ashpan. Do
not use bare hands to operate the riddling system.
4.7 Then open the Primary air control fully for a few minutes,
to establish a glowing bed before adding new fuel.
4.8 Allow the new fuel to burn at high output for a few minutes
before adjusting the burn rate with the Primary air control
to the desired setting. It is best to refuel little and often to
maintain clean and efficient burning.
4.9 The ideal control settings to suit the particular installation
and personal preferences will be established by experience
in using the stove.
4.10 The maximum height of fuel in the Riva stove must not
exceed the secondary air holes in the Stainless Steel fascias.

WARNING
Do not use the door as a rest or support when refuelling
or adjusting the air controls as this could cause
permanent damage to the appliance.
5.1 The burning of any fuel will produce ash, which will have to
be removed after a period of use. This time will depend on
the fuel used. Before removing the ash from the stove it is
advisable to let the fire burn down to a low level, or even
go out completely. The ash pan can the be removed from
the appliance using the tool provided, after lowering the
access cover below the door.
5.2 As heat can remain in the ash for a long period after use
care must be taken when removing and carrying the full
ashpan. We suggest that the ashpan is carried using gloved

hands. Or the ash is placed directly in to a Stovax Ash
Caddie. (Stovax part number 4227)
5.3 When burning wood the of ash will be smaller and may
only need removal once every week. To do this, allow the
fire to burn out and cool. Then after removing the log
retainer scoop out the ash with a suitable shovel. It is best
to leave a layer of ash in the stove to form a bed for the
new fire.
5.4 Do not place ash in a bin made from plastic or any other
combustible material.
6.1 Wood: - Burn only seasoned timber, with a moisture
content of less than 20%. In most cases this would require
drying cut wood for 12 to 18 months before use. Poor
quality timber could cause low combustion efficiency,
produce large amounts of harmful condensation, which
could reduce the effectiveness of the airwash system, and
ultimately the life of the stove Do not burn painted,
impregnated wood or manufactured board products.
The symptoms of poor performance related to wet wood
include:-
• difficulty getting a fire going and keeping it burning well,
• smoky fires with little flame,
• dirty glass,
• rapid creosote build-up in the chimney,
• low heat output,
• Short burn times, excessive fuel consumption and
blue/grey smoke from the chimney.
To help avoid large build-ups of tars and creosote within in
the stove and the flue system, it is recommended to burn at
high output for at least 30 minutes each day. The use of
Stovax Protector chimney cleaner will also help to reduce
this problem.
6.2 Solid fuel: - Burn manufactured smokeless fuels, or
anthracite, listed as suitable for use with closed heating
stoves. Do not burn ‘petro-coke’ or other petroleum
based fuels, as this will invalidate and product
guarantee.
6.3 Fuel consumption: -
Wood:- Approximately 1.8 kg per hour of fuel under ideal
conditions with the Airwash control fully OPEN and the
Primary air control fully CLOSED
Solid Fuel:- Approximately 0.7 kg per hour of fuel under
ideal conditions with the Airwash control fully CLOSED and
the Primary air control fully OPEN.
