Flue / Chimney Requirements
IMPORTANT - The stove must not be installed into a chimney that serves any other heating
appliance, i.e. must not be fitted as part of a shared flue.
The flue must meet the following conditions:-
•
This appliance must be installed into a ‘Class 1 Chimney’. If there is no existing
chimney, then an approved solid fuel, factory built, prefabricated block type or a twin
walled, stainless steel flue can be used. Get advice from a qualified chimney installer
e.g. a HETAS registered engineer.
•
The flue diameter to fit the appliance must be 150mm / 6 inches.
•
To perform satisfactorily, the chimney/flue height must not be less than 4.6 metres
from the base of the appliance.
•
The top of the flue pipe must be a minimum of 600mm above the ridge of the roof if
the flue penetrates the roof within 3 metres of the ridge. Or if more than 3 metres
horizontally from the roof line, have a minimum height of 1 metre.
•
If the upward draft is insufficient or periodic down drafting occurs and the appliance
smokes or only burns slowly, it can be resolved by extending the flue or fitting a
specialist cowl.
•
All flue pipe has to be suitable for solid fuel and fitted in accordance with building
regulations, whilst complying with local and current legislation and manufacturer’s
instructions.
•
Both the chimney and flue must be accessible for periodic cleaning.
•
If the appliance is fitted into an existing chimney, ensure that it is sealed at the base
of the chimney with a register plate and fit the flue pipe up through the plate and
continue the flue until it terminates outside the chimney in accordance with Building
Regulations Approved Document J.
Ventilation
The burning of wood involves oxygen consumption. It is important that the room in which the
appliance is installed should be sufficiently ventilated.
Insufficient ventilation may disrupt the combustion process and cause the smoke flow through
the chimney to be interrupted, which may lead to smoke emissions into the room.
The Baker's Oven requires ventilation in accordance with Building Regulations Approved
Document J. If necessary, you can install a ventilation grill to provide a constant flow of fresh
air in the room. This precaution is particularly necessary in well-insulated rooms with
mechanical ventilation. Be sure that the ventilation grill is not liable to any form of blockage.
Ensure not to use other air-consuming appliances, such as heaters, cooking hoods, bathroom
ventilators, in the same room or in the house while the stove is burning, or make sure to have
an extra ventilation grill installed for these appliances.
Lighting the Baker's Oven
Prior to lighting the Baker's Oven, check the metal strip at the top of the firebox door. The strip
should be set leaving a gap of 1mm between the edge of the strip and the front of the Baker’s
Oven. This gap provides the secondary air supply and can be adjusted in and out with the
allen key provided. If this gap is set too wide, the burn rate of the stove will be difficult to
control. If the gap is set too close, the air-wash over the glass will not function correctly.
