ULTRATEMP ETI™ Hybrid Heater Installation and User’s Guide

Flue Gas Condensation
Management
The UltraTemp ETi™ Hybrid Heater is a condensing
appliance. The flue gases will produce condensate
while in operation and must be drained correctly.
The condensate pH level is between 3.1 and 4.2.
Pentair recommends neutralizing the condensate
to avoid potential damage over time to the drainage
system, and to comply with local water authorities
where applicable. To neutralize the condensate, use
the Condensate Neutralizer Cartridge provided with
the heater. The condensate drain must be installed
so as to prevent accumulation of condensate. When
a condensate pump is not used, the tubing must
continuously slope downward toward the drain with no
spiraling.
Note:
Consult local codes for treated condensate
disposal method.
DO NOT allow the exhaust flue gases to vent
through the neutralizer. All condensate drains
MUST have a trap to prevent flue gas leakage. Flue gas leakage can
cause personal injury or death from carbon monoxide. Check with local
authorities for regulations regarding discharge of condensate to the drain
sewer system.
pH levels of 5.0 and below may harm some floor
drains and/or pipes, particularly those that are metal.
Ensure that the drain, drainpipe, and anything that will come in contact
with the condensate can withstand the acidity. Damage caused by failure
to install a neutralizer kit or to adequately treat condensate will not be the
manufacturer’s responsibility.
Preventative Maintenance
Annual condensate assembly inspection:
Inspect
the internal tubing top for any dirt or particles that
could collect and clog the condensate neutralizer
cartridge.
Based on operating conditions, algae buildup in the
condensate cartridge may occur. Excessive algae
buildup can prevent proper condensate drainage

Condensate Cartridge Service
If the control board reads “REPLACE CNC”, check
pH of condensate liquid. If the pH is below 5.0,
replace the condensate cartridge with a Condensate
Neutralizer Kit, (P/N 475954).
If the pH is not known, replace the condensate
cartridge when the control board recommends.
To clear this alarm, press the DOWN arrow and MODE
button simultaneously. The alarm may take a few
moments to clear after the buttons are pressed.

ENGLISH
DO NOT expose the condensate cartridge to
freezing temperatures without draining. This
could damage the cartridge. See page 34 for proper Winterizing
instructions.
