d. Slope horizontal vent pipe minimum 1/4 in/ft
(21 mm/m) downward towards the boiler.
Les chaudières de catégories I, II et IV doivent
présenter des tronçons horizontaux dont la pente
montante est d'au moins 1/4 po par pied (21
mm/m) entre la chaudière et l'évent.
e. If possible, slope horizontal combustion air
pipe minimum 1/4 in/ft (21 mm/m) downward
towards terminal. If not, slope towards boiler.
f. Use noncombustible ¾ in. pipe strap to support
horizontal runs and maintain vent location and
slope while preventing sags in pipe. Do not
restrict thermal expansion or movement of vent
system. Maximum support spacing 4 ft. (1.2 m).
Avoid low spots where condensate may pool.
Do not penetrate any part of the vent system with
fasteners.

prévenir le fléchissement. Les méthodes et les
intervalles de support doivent être spécifiés.
Les instructions divent aussi indiquer les
renseignements suivants:
les chaudières de catégories II et IV doivent être
installées de façon à empêcher l´accumulation de
condensat: et
si nécessaire, les chaudières de catégories II et IV
doivent être pourvues de dispositifs d´évacuation
du condensat.
g. For multiple boiler installations with vertical
roof terminals, separate vent pipes from multiple
boilers may be piped through a common conduit
or chase so that one roof penetration may be
made.
3. Vent/Combustion Air Terminals
Install venting system components on exterior
of building only as specifically required by these
instructions (refer to Figure 4).
