5.11 Condensate Piping
• Use materials acceptable to authority having
jurisdiction. In absence of such authority:
• USA - PVC or CPVC per ASTM D1785/D2845
Cement or primer per ASME D2564 or F493.
• No external trap needed.
• Connect condensate hose, hose clamps, and
coupling to boiler drain trap as shown in figure 5-26.
• Connect condensate piping to 3/4" PVC as shown.
• Slope condensate drain pipe minimum 1/4" per foot
(21 mm/m) away from boiler.
• Support condensate pipe to eliminate any sages.
•
Use field source condensate pump, designated for
use with condensing boiler, if boiler located below
disposal point.
•
Condensate pump should have overflow switch.
Condensate from Boiler is slightly acidic and may
cause property damage if overflow.
• Field source condensate neutralizing kit as
required by authority having jurisdiction or for
environmentally friendly condensate disposal.
