4.4.7 Condensate drain and piping
The SSB boiler is designed to condense water vapor from the ue
products. Each module of the boiler is equipped with a condensate drain
system (see Fig. 18), connected to the condensate horizontal manifold.

WARNING: At the Start-up and after prolonged shutdown
of the boiler, the syphon must be lled with water prior to
restart it, otherwise combustion gases will enter the room
with a risk of an excessive level of carbon monoxide.
The procedure for lling the traps and syphon with water is shown on the
Fig. 19:

• The installation must have provisions for suitable drainage or
collection of the condensate out of the boiler traps.
• The condensate water shall be discharged at atmospheric pressure,
by dripping into a suitable drain, and shall be neutralized prior to
draining per local codes.
• The condensate drain tube must pitch away from the boiler (1/4” slope
per foot) and must never reduce its diameter downstream.
• Never use copper pipes or of other material not intended for the
specic purpose, because the action of condensate will cause a rapid
deterioration.
• Check that the condensate drain pipe is adequately sloping towards
the discharge point avoiding high points, which can inhibit the ow of
condensate. The condensate pipe must be installed in such a way so
as to avoid the freezing of the liquid.

WARNING: Verify condensate disposal / neutralization is in
accordance with local, state and federal regulations.
If a oor drain is not available, a condensate pump can be used to
remove the condensate to drain. The maximum condensate ow rate is
6.2 GPH for SSB 800 SA and 7.9 GPH for SSB 1000 SA / 1000 TL. The
drain line must be removable for routine maintenance.

CAUTION: Use PVC, CPVC, stainless steel, aluminum or
polypropylene for condensate drain piping (Fig. 20). DO
NOT use carbon or copper components.

4.4.8 Electrical Connection
The voltage conguration of SSB 800 SA, 1000 SA and 1000 TL is as
follows:
• 120VAC, 1-Phase, 60 Hz
Each boiler must be connected to a dedicated electrical circuit.
NO OTHER DEVICES SHOULD BE ON THE SAME ELECTRICAL
CIRCUIT AS THE BOILER.
