2.4. COMBUSTION AIR PIPE SIZING
In computing the pressure loading effect of the combustion piping system an equivalent straight-
length of piping is used. This equivalent length of piping is the combined sum of all equivalent lengths
of piping and piping components used in construction, including:
1. All straight horizontal and vertical pipe sections.
2. All equivalent lengths of fittings, bends and end terminations.
3. All equivalent lengths associated with extrance or transition effects, for example a sudden
expansion or contraction.
Table 3 provides the required combustion pipe size for both Innovation and ReCon water heaters
along with some rule-of-thumb guidelines for estimating the equivalent lengths of common piping
components.

* Note : The maximum combined pressure drop of the exhaust and intake-air vents is 140
equivalent-feet (42.7 m) for 6” (152 mm) pipe (all models). For the INN600 using 4” (102
mm) pipe the maximum combined pressure drop of exhaust and intake-air vents is 80 (24.4
m) equivalent-feet. See Section 3.4.
