NOTES:
1) See vent system manufacturer’s literature for other part numbers that are required such as straight pipe, elbows, fi restops and
vent supports.
2) In addition to terminals shown, Crown coaxial terminals may be used in some cases. See Table 3 for applications and Crown
part numbers.
3) All Heat Fab condensate traps shown may be installed in vertical or horizontal run.
4) Protech FSCD4 condensate trap may be installed in a vertical or horizontal run. All other Protech traps must be installed in a
horizontal run only.
5) Heat Fab Saf-T Vent SC may not be used for horizontal coaxial venting - a separate air inlet pipe must be provided for hori-
zontal direct vent systems. SC03HT or SC04HT adapters are used to adapt from SC pipe to terminal. Use of SC pipe in horizon-
tal systems does allow for reduced clearances to combustibles in some applications. See Table 2.
6) Heat Fab SC03VT or SC04VT adapters are required on any vertical vent system using Saf-T Vent SC even when combustion
air is obtained through a separate pipe or from the boiler room.
7) Metal-Fab CGSWDS condensate traps may only be installed in a horizontal run.
