4.5 Daily Firing
The boiler should not be started nor should more wood be added until the thermal storage system is
cool enough to absorb the heat produced by an additional firing. For most applications the tank should
be able to rise 40 °F (20 °C) per load of wood. Depending on the load placed on the heating system, a
single firing of wood during the non-heating season may produce enough energy to last from 5 to 10
days. During the heating months, most owners will find that loading each 12 or 24 hours with a fresh
load of wood is adequate.
If loading within a 12 hour interval, it may be possible to re-kindle the
fire by placing fresh wood in on top of red coals.
Kindling may not be necessary. It is good prac-
tice to clean out the “U” shaped tunnel stone, accessed through the ash door, before each firing. If
black cinders are present, leave them between the U stone and door, they will be burned. Only remove
the ash if possible.
4.6 Shutting Down the Boiler
Switch off the boiler by turning off the fan switch on the control panel. The circulating pump will
shut off when the boiler is cool. Take care not to shut off power to the boiler circulator if there is any
chance that the boiler may heat up again.
4.7 Operation with Thermal Storage System
Tarm Biomass requires that the Solo Innova be permanently connected to a Thermal Storage System.
The boiler will always be able to discharge its heat resulting in better combustion, less depositing of
soot and tar, and longer boiler life. Operation is simplified as the filling chamber can be completely
filled. The boiler can be fired when you have time and the house can be supplied with heat as required
from the thermal storage system. An added benefit is that domestic hot water can also be created in
the reservoir. Keep in mind that the amount of wood placed in the boiler’s filling chamber depends on
the size and the temperature of the heat storage reservoir. The boiler should not be fired beyond the
reservoir’s heat storage capacity. Do not add wood until the temperature in the thermal storage system
has fallen to 140-160 °F (60-72 ºC). so that the reservoir will again be able to absorb heat. Set the
boiler temperature to a maximum temperature of 180° F (82 ºC).
4.8 Creosote
Tar deposits are not normally a problem in a Solo Innova which is fired as directed. If soft or tar like
creosote is found in the firebox can be a symptom that the boiler is being filled with more wood than
is necessary. Glazed, crunchy and scaly creosote in the main firebox is common and expected.
Glazed, crunchy, or scaly creosote should never be found in the lower combustion chamber, heat ex-
change tubes, or in the chimney. When wood is burned slowly, it produces tar and organic vapors,
which combine with expelled moisture to form creosote. The creosote vapors condense in the rela-
tively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue
lining. When ignited this creosote makes an extremely hot fire. The chimney and chimney connector
should be inspected at least twice monthly during the heating season to determine if a creosote build-
up has occurred. If creosote has accumulated it should be removed to reduce the risk of a chimney fire.

NOTE
If wood is stored in the boiler room, ensure that it is not stored within the clearances to
combustibles or in a way that will impede daily firing or maintenance.
WARNING
It is important to keep the load and ash doors closed during operation and to maintain the
door seals in good condition.
