4.7 Combustion Condensate
The condensate disposal system of the Hi-E
2
pool
heater is quite simple, but must be properly installed
and maintained. See the installation instructions for
information on correct tubing installation. Condensate
drainage should be observed routinely and if necessary,
the flow-ways should be cleaned.
In normal operation, condensate drains from the
condensate collector behind the combustion fan. A 5/8"
I.D. drain tube conducts this water into the condensate
trap/neutralizer, where a “water seal” prevents room
air from being pulled into the system. The water seal of
the trap prevents vent gases from being discharged into
the room. A smaller amount of condensate may drain
from the vent duct and blower. See Figures 12 and 13
in the Condensate Disposal section of the installation
instructions.
During start-up, condensate from the collector cannot
reach the trap unless the water seal is established. This
can be done by pouring water into the trap. The heater
will self-prime by driving water into the vent outlet, from
which it will eventually drain into the trap. However, it is
better to avoid this by manually priming the trap.
If condensate is not draining from the system, check
for improper routing of the drainage tubes or blockage
in the drainage system. Tubing must be installed with a
continuous fall in the direction of condensate flow. Sags
may trap water, defeating the intended operation. Check
for blockage by disconnecting drainage tubes at the
collector and the vent diffuser. Probe these openings with
a tool or wire hook to dislodge any debris.
Limestone gravel neutralizer is required in the condensate
tray to prevent corrosion. This material should be replaced
once a year to assure its continuous benefit. Replacement
packages are available from Zodiac
®
or its representatives.
It is normal that a blue/green deposit forms in the
neutralizer. This is caused by very small concentrations of
copper ions present in the condensate. By increasing the
pH of the condensate, the limestone causes this material to
precipitate and be retained in the gravel.
4.8 Major Component Service
The venturi assembly, the burner assembly and the heat
exchanger tube assembly can be replaced if necessary,
but correct procedures and use of only factory-provided
parts are essential to assure satisfactory service and safe
operation. Sealing the system with the specified sealers
and gaskets is especially important. Contact Zodiac

Dimensions
5.1 General Information
• The Hi-E2 is design certified by CSA International as a
swimming pool heater under ANSI Standard Z21.56 for
use in the United States and Standard CSA-4.7 for use in
Canada.
• The Hi-E2 pool heater is certified for use indoors or
outdoors in the United States.
• The Hi-E2 pool heater is for use with natural or liquefied
petroleum gas. Ratings apply to either fuel.
• De-rating for elevation is not necessary because of the
Hi-E2 heater's special combustion system. Reduced
barometric pressure at high elevations naturally
decreases input and output by approximately 3 percent
per 1000 feet above sea level.
• Heaters require 115V, 60Hz electrical power.
• Working pressure 75 psig.
