Condensate Piping; Modular Boiler Control Systems - Burnham Revolution Installation, Operating And Service Instructions

G.
Electrical
1. Each boiler must be provided with a fused
disconnect and service switch.
2. Install wiring in accordance with requirements of
authority having jurisdiction. In the absence of such
requirements, follow the National Electric Code,
NFPA 70 and/or CSA C22.1 Electric Code.

Condensate Piping

1. Each boiler requires a separate condensate drain
line. Do not manifold condensate drains from
multiple boilers together.
2. A common condensate pump/sump may be used.
Run separate condensate piping from each boiler to
the sump. A common drain may be used to
discharge condensate from the sump.
Consult pump/sump manufacturer for compatibility
of materials of construction with flue gas
condensate. If a common pump/sump is used,
individual boiler drain lines must be connected such
that one drain pipe cannot back feed into another
boiler drain.
3. Consult local authorities regarding disposal of flue
gas condensate into public waste water system.
Some jurisdiction requires that the condensate be
buffered before discharge. This buffering is
commonly achieved by draining the condensate
through a limestone bed. Consult chemical
treatment company for buffering systems.

Modular Boiler Control Systems

Contact a controls manufacturer such as Honeywell or
Tekmar to properly apply a modular control system.
Common systems may use outdoor temperature, return
water temperature or both to stage the boilers.
