MASONRY FIRE PLACE
Before the installation the entire fireplace system should
be inspected for condition and code compliance prior to
connecting to the fireplace chimney. Older fireplaces and
chimneys may not have been constructed to current-day
codes.
The fireplace and chimney should be in, or bought up to
acceptable condition and proper clearances should be
met before connecting to the fireplace chimney.
The size of the flue must be considered. If the fireplace
chimney is too large, a relining system may be installed
using an approved relining system.
Connection to a masonry chimney may be done by
breaching into the chimney from the front of the fireplace,
no less than 8” above the bottom of the first flue tile, by
installing a stainless steel or other listed chimney con-
nector from the appliance flue outlet up through the fire-
place damper and smoke chamber, terminating at the first
flue tile, or by installing a stainless steel or other listed
relining system from the flue outlet up the entire length of
the chimney, where necessary.

or back drafts occur whether or not there is com-
bustion present.
2.
Existing fuel-fired equipment in the house, such
as fireplaces or other heating appliances, smell,
do not operate properly, suffer smoke roll-out
when opened, or back-draft whether or not there
is combustion present.
3.
Opening a window slightly on a calm (windless)
day alleviates any of the above symptoms.
4.
The house is equipped with a well-sealed
vapour barrier and tight fitting windows and/or
has any powered devices that exhaust house air.
(e.g. extraction hoods or tumble dryers)
5.
There is excessive condensation on windows in
the winter.
6.
A ventilation system is installed in the house.
If these or other indications suggest that infiltration air is
inadequate, additional combustion air should be provided
from the outdoors. Outside combustion air can be pro-
vided to the appliance by the following means:
1.
Indirect method: for an appliance not certified for
direct connection of outside combustion air, the
outside air is ducted to a point no closer than
(12”) 300mm from the appliance, to avoid affect-
ing the performance of the appliance.
2.
A mechanical ventilation system: if the house
has a ventilation system (air change or heat
recovery):
a. The ventilation system may be able to provide
sufficient combustion make-up air for the solid-
fuel-fired appliance.
b. The householder should be informed that the
ventilation system might need to be re-balanced
by a ventilation technician after installation of the
appliance.
VENTILATION & COMBUSTION AIR
REQUIREMENTS
Ventilation and an adequate air supply is necessary to
supply combustion air to the appliance. Refer to your
Local Authority for current requirements in your jurisdic-
tion.
Outside combustion air may be required if:
1.
The solid-fuel-fired appliance does not draw
steadily, smoke rollout occurs, fuels burns poorly,
SPILLAGE TEST
In all installations a spillage test should be carried
out to ensure there is sufficient combustion air and
the flue system is
1.
Light/burn appliance under normal condi-
tions in accordance with this installation
manual.
2.
Close all doors and windows.
3.
Operate all appliances requiring air at full
rate (eg. extraction hoods, tumble dryers
etc).
4.
Check for spillage.
LOCATION:
There are several conditions in selecting a LOCATION for
your 104 MK II. These are:-
