Solo Innova Instructions 1-800-782-9927 Version 01-18
Tarm Biomass · 4 Britton Lane · Lyme, NH 03768
Carefully engineered
heat exchange tubes
downstream from the combustion process are fitted with
removable
turbulators
to help ensure that a maximum amount of energy is transferred from the fuel
to the hot water jacket. The heat exchange tubes can be accessed for cleaning through the
access
panel and door
located at the top rear of the boiler
Operation of the fan assumes that the boiler
can discharge its heat continually. The Solo Innova must always be connected to a buffer tank of
adequate size
.
2.2.3 Safety Systems
The Solo Innova comes with safety systems to prevent the following:
Pressure in the boiler exceeding 30 psi (2 bars) (over pressure)
Boiler water temperature exceeding 212 ºF (100 ºC)
To prevent an
over-pressure
condition, an ASME stamped pressure relief valve (provided) needs to
be installed on the boiler which opens at 30 psi to relieve the boiler pressure
(See Section 3.5.1). Nor-
mal pressure in the boiler should be between 12-15 psi.
On the control panel there is an overheat thermostat. If the boiler exceeds (212 ºF) 100 ºC it will shut
off the fan to the boiler.
A gravity over-heat dump loop is also required. In the event of a power failure this loop should provide
dissipation for at least 10% of the boiler’s maximum rated output, assuming an ambient temperature of
65 ºF. in the area heated by the loop, and a mean water temperature of 180 ºF (82 ºC)
(See Section
3.4.2).
2.2.4 Accessories
The boiler is shipped with loose and installing parts. See
Section 3.3.2
for a complete listing of these
parts. Cleaning tools are provided with the boiler.
A
barometric damper
(draft stabilizer) is available for regulating chimney draft.
Plumbing around the boiler must include a three-port mixing valve in the orientation shown on instal-
lation drawing. The valve must be a
Termovar Model 4440A-3
or equal with a 72 ºC element. Tarm
Biomass provides this valve at an extra cost.
A
flue thermometer
(Part #3339N)
is highly recommended to help monitor the performance of the
Solo Innova. This part is available from Tarm Biomass .
A
Thermal Storage System
is available from Tarm Biomass.
2.3 Fuels
Chemically treated or painted wood is unsuitable as fuel. The
Solo Innova boiler is designed for
burning of cord wood only.
Wood briquettes or manufactured pure wood logs can also be used as
fuel provided they have a minimum cross section of 2.5 sq in.
Manufactured logs should be at least
12” (0.25m) in length. Excessively small and compact pieces of wood or wood pellets are not suit-
able. Coal cannot be used as it becomes too compact and closes the combustion slot. The fire box can
be filled to the top.
