WARNING
!
Asphyxiation hazard! Fill condensate trap before
starting boiler to avoid combustion products escaping
boiler. Failure to follow these instructions could result
in death or serious injury.

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 for 165/205 or
1/2" PVC for 100/115/125/150 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.
