6.11 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.
• Canada - CSA or ULC certified PVC/CPVC pipe, fittings and cement.
• No external trap needed.
• Connect condensate hose, hose clamps, and coupling to boiler drain trap as shown in figure 6-30.
• 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.
Manufacturer requires an air vent be used to prevent condensate line vacuum lock.
