NOTES 1. Vent must be Class 100, 125 or Schedule 40 PVC or CPVC, Schedule 80 PVC or CPVC. Combustion air pipe may be PVC, CPVC or suitable metal pipe.
2. Heavy condensation occurs in long vent pipes. Provide a separate entrapped condensate drain from vent piping near heater when 5” vent pipe exceeds 100 feet or 6” vent pipe
exceeds 50 feet.
*
• For saltwater version heaters (EHE350NS and EHE350PS) a 180°F vent limit switch is required and PVC venting is not allowed.
• Allmetalsectionsoftheventingsystemusedmustbestainlesssteelandlisted/certied/classiedbyaNationallyRecognizedTestingLaboratory(NRTL)as
being compliant with the applicable requirements of the Underwriters Laboratories (UL) standard for safety for “Venting Systems for Gas-Burning Appliances,
Categories II, III, and IV” (ANSI/UL 1738), and properly installed in accordance with any manufacturers’ instructions and in compliance with applicable local and
national installation codes.
• Thenon-metallicsectionsoftheventingsysteminstalledmustalsobelisted/certied/classiedbyaNationallyRecognizedTestingLaboratory(NRTL)as

manufacturers’ instructions and in compliance with applicable local and national installation codes.
2.7.3.3 Size and Length of Combustion
Air and Vent Piping
Piping for combustion air and venting must be large
enough to avoid restriction of the heater combustion
system. Pipe diameter, number of elbows and length of
pipe determine how much it restricts ow to or from the
heater. Table 3 species the allowable length of piping for
various situations.
The following example illustrates use of table 3:
EXAMPLE: A model 350 heater is to be installed in a
one-pipe system with schedule 40 PVC or CPVC, see
Figure 6. The vent pipe run is 42 feet long and has
2.7.3.2 Piping Materials
WARNING
To avoid risk of property damage, serious injury, or
death, use ONLY piping materials from the list below
which are certified or listed for the application per
the requirements of UL 1738 and/or ULC S636, by a
Nationally Recognized Testing Laboratory (NRTL).
Vent piping must be corrosion resistant because
combustion condensate is usually present on its internal
surfaces. The materials listed in Table 3. are acceptable
for vent piping:
