CAUTION
The condensate line must remain unobstructed,
allowing free flow of condensate. If condensate
is allowed to freeze in the line or if the line is
obstructed in any other manor, condensate can
exit from the boiler tee, resulting in potential
water damage to property.

CLEAN OUT PORT
When installing a condensate pump, select one
approved for use with condensing boilers and
furnaces. The pump should have an overflow
switch to prevent property damage from
condensate spillage.
Condensate from the Mod Con Boiler will be
slightly acidic (typically with a pH from 3.2 to
4.5). Install a neutralizing filter if required by
local codes.
