Freeze Protection Operation
Stage 1
- If control detects water temperature of 46
o
F
(8
o
C) and below, it turns the internal and external
pumps On for 600 seconds and Off for 30 seconds.
This cycle repeats until the control detects inlet water
temperature of 50
o
F (10
o
C) and above.
Stage 2
- If control detects water temperature of
41
o
F (5
o
C) and below, it turns the burner on to meet
a target temperature of 104
o
F (40
o
C). The burner
and internal and external pumps will continuously
during this stage until the control detects inlet water
temperature of 104
o
F (40
o
C) and above.
Stage 3
- If control detects water temperature of 34
o
F
(1
o
C) and below, Er: 85 will appear on the display.

G. Water Temperature Adjustment and Scalding
This water heater can
deliver scalding water. Be
careful whenever using
hot water to avoid scalding
injury. Certain appliances
such as dishwashers and
automatic clothes washers
may require increased
water temperatures. By
setting the thermostat
on this heater to obtain
the increased water
temperature required by
these appliances you may
create the potential for
scald injury.
To protect against injury,
install a mixing valve in the
water system. This valve
will reduce point of use
discharge temperatures
by mixing cold and hot
water in branch supply
lines. Such valves are
available from your local
plumbing supplier.
Table 3 details the relationship of water temperature and time with
regard to scald injury and may be used as a guide in determining the
safest water temperature for your applications.

Table 3 - Time and Temperature Relationship in Scalds
Households with small children, disabled, or elderly persons may
require a 120
o
F or lower temperature setting to prevent severe
personal injury or death due to scalding.
An ASSE 1017 or ASSE 1070 temperature limiting or mixing valve is
recommended in installations servicing disabled or elderly persons,
or children. Mixing valves do not eliminate the risk of scalding.
To avoid scalding:
•
Set the water heater set point temperature as low as possible.
•
Feel water before bathing or showering.
•
If thermostatic valves are required, use devices specifically
designed for such purpose. Install these devices in accordance
with instructions provided by the manufacturer.
Failure to install a temperature limiting or mixing valve and follow
these instructions could result in property damage, severe personal
injury, or death due to scalds.
H. High Elevation Installations
Natural gas at high elevation might contain less heating value than
typical 1,000 BTU/cu ft and therefore can cause improper air / gas
mix leading to improper combustion. For natural gas installations
above 3,000 ft, call your gas provider to determine the heating value
of the supplied natural gas.
NOTE:
Damages resulting from incorrect installation or from use of
products not approved by the manufacturer ARE NOT covered by
warranty.
