ABOUT JD 27/JD 227
Manufacturer’s warranty
This product has been manufactured in accordance with
the type approval document for the product, which
includes the installation and maintenance instructions as
a related document.
General
The JD 27/JD 227 is made of heavy cast iron and the
firebox is lined with protective cast iron. Between the
vermiculite lining and the thick cast iron sides there is
an air gap, with oval holes in the top, providing for good
circulation of air to prevent overheating of the sides.
With its heat-retaining materials, the stove gives off good
after-heat for several hours after it stops burning.
The fire door is provided with a window of ceramic-hard-
ened glass to view the fire. Thanks to the tight covers and
the special supply of air to the fire, the stove maintains
a maximum heat output and low wood consumption.
The wood burns when the supply of secondary air flows
through the holes in the vermiculite sides and through
primary air supplied when the fire door is ajar in the light-
ing-up phase. The JD 27/JD 227 is fitted with a throttle
valve and a removable hotplate.
HERE IS HOW YOUR JD 27/JD 227
WORKS
Combustion air
Primary air is supplied when the fireplace door is slightly
open during refill and during the firing phase. There is
also a primary air damper that is regulated on the lower
part of the fireplace door. This damper is used if you need
to get a little more speed on the fire when the fireplace
door is completely closed.
Secondary air is supplied by a fresh air intake under the
stove. Secondary air is then warmed up into the stove
and finds it’s way into the fire through the holes on the
cautery in the fireplace.
The flames leave the fireplace by crossing the oven
ceeling and the flames are once again oxygenated
through the airpipe for optimal incineration. Then the
flames travel down on the right side of the stove. Then
towards the back of the stove and leave the stove at the
back or alternatively at the top due to connection to the
chimney.
** Connection pad is an option and is included in the outdoor air connection kit.
This is where you adjust the secondary
supply air by turning the knob downwards.
