3.1.5 Electrical
For the Solo Plus boiler a
120 VAC, 60 hertz, 2-wire power supply is required
. This electrical con-
nection should be from a dedicated 15 amp, circuit breaker. A master service switch for the boiler,
mounted on the wall in the proximity of the boiler, is recommended. Locally enforced electrical codes
must be followed.
3.2 Preparing the Chimney
The chimney is one of the most critical factors in the successful operation of any solid fuel heater, in-
cluding the Solo Plus boiler. A good chimney will provide a continuous and dependable draft to pull
the exhaust gasses out of the building.
Follow manufacturer’s installation instructions for installing and supporting any specific chimney
product.
Flue gas exhaust temperatures can be low enough to cause condensation in chimneys. Condensation
will, over time, damage a masonry chimney. Accordingly, installation of a stainless steel chimney
liner (made with 316 or AL-294C alloys) inside the chimney flue is strongly recommended.
At the connection to a factory-built chimney, a dripless adaptor must be used.
The chimney draft must be stable and between -0.025‖ (-0.6 mm) and -0.05‖ (-1.25 mm) water col-
umn.
The top of chimney must be 3 feet (0.9 m) above the roof and 2 feet (0.6 m) above any structure
within 10 feet (3.0 m) measured horizontally.
For the Solo Plus 30 and 40 best draft will be provided by a chimney which has an 6‖ (152 mm) ID
round flue, is 20-30 feet (6.0-9.0 m) in height and which is located inside the heated structure. The
Solo Plus 60 will need an 8‖ (203 mm) ID round flue. The chimney must be capable of maintaining a
breech draft of -0.05‖ WC (-1.25 mm) during normal boiler operation.
Your Solo Plus gasification boiler is designed to burn efficiently and with virtually clear emissions,
but under certain conditions creosote deposits can form in your chimney. Chimneys that are too large,
are poorly insulated, or have bends in the flue passages are especially prone to problems with draft
and/or creosote.

NOTE
The boiler must be connected to a tile-lined masonry chimney or to a Factory-Built Type UL
103 HT (ULC S629 in Canada) approved chimney. The chimney must be in good condition. If
the boiler is connected to a dirty or inadequate chimney, it can present a serious fire hazard.
All chimneys and connections must conform to NFPA standard #211. No other appliance
should be connected to this flue unless allowed by the local code authority. Consult your local
inspector for chimney requirements and install the boiler in accordance with all applicable
codes. Please review the following diagram before connecting the boiler to the chimney.
