Table 6. Category lll, Vent Manufacturer's Model
Numbers (abbreviated)
Installations must comply with applicable national, state
and local codes.
2.C.4 Vent Adapters
The unit ships from the factory with a Category I, B
vent connection. To convert to Category III select a vent
adapter from the Cat III vent adapter table. This adapter
will reduce the diameter and convert the vent pipe style to
Cat II/IV FasNSeal vent pipe. If other vent manufacturers
material will be used during installation the appropriate
vent adapter must be purchased separately. All installed
vent adapters must be sealed using gaskets or silicone.
See Table 7.
in the venting system manufacturer’s Installation
Instructions. Horizontal portions of the venting system
must be supported to prevent sagging and may not
have any low sections that could trap condensate.
The unit must not support the weight of the vent pipe.
Horizontal runs must slope downwards not less than ¼
inch per foot (2 cm/m) from the unit to the vent terminal.
Reference
Table 2
for the size of the Category III vent
system. Up to 100 Ft of vent can be used. For each
elbow subtract 5ft of vent length from the total allowable
length of vent pipe.
2.C.2
Exhaust Vent Terminal
An exhaust vent terminal must be installed. If an
exhaust vent terminal is not available with the certified
vent system, the manufacturer suggests the use of a
coupler fitting from the certified vent system into which
the vent terminal screen can be installed. Be sure
to install and terminate both vent and combustion air
pipes per the instructions in this section.
See Table 8.
2.C.3 Vent and Air Pipe Material
This unit requires a special venting system. Refer to
venting supplier’s instructions for complete parts list and
method of installation. The manufacturers and product
lines listed in Table 6 have been tested and authorized
to safely operate with this equipment. Suppliers of
stainless steel that are not listed on these tables are not
permitted for use with this appliance. See Table 8.
Do not mix venting suppliers and models in venting
systems. Failure to comply could result in personal
injury, property damage, or death.
