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 2 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 2 - 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.
This indirect fired water heater is deemed to be used in a commercial
setting if at any time the unit is operated at a temperature over
150
o
F. Refer to the warranty for additional information.
Part 2 - Prepare the Water Heater
COLD WEATHER HANDLING
- If the water heater has been stored
in a very cold location (BELOW 0
o
F) before installation, handle with
care until the components come to room temperature. Failure to do
so could result in damage to the water heater.
Remove all sides of the shipping crate to allow the heater to be moved
into its installation location.
UNCRATING THE WATER HEATER
- Any claims for damage or
shortage in shipment must be filed immediately against the
transportation company by the consignee.
Carefully consider installation when determining heater location.
Please read the entire manual before attempting installation. Failure
to properly take factors such as heater venting, piping, condensate
removal, and wiring into account before installation could result in
wasted time, money, and possible property damage and personal
injury.
This water heater is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by warranty.
Failure to install the water heater indoors could result in property
damage, severe personal injury, or death.
A. Locating the Water Heater
Incorrect ambient conditions can lead to damage to the heating
system and put safe operation at risk. Ensure that the installation
location adheres to the information included in this manual. Failure
to do so could result in property damage, serious personal injury, or
death. Failure of heater or components due to incorrect operating
conditions IS NOT covered by product warranty.
This water heater must be installed upright in the vertical position as
described in this manual. DO NOT attempt to install this water heater
in any other orientation. Doing so will result in improper water
heater operation and property damage, and could result in serious
personal injury or death.
The service life of the water heater’s exposed metallic surfaces,
such as the casing, as well as internal surfaces, such as the heat
exchanger, are directly influenced by proximity to damp and salty
marine environments. In such areas higher concentration levels of
chlorides from sea spray coupled with relative humidity can lead to
degradation of water heater components. In these environments,
heaters must not be installed using direct vent systems which draw
outdoor air for combustion. Such heaters must be installed using
room air for combustion. Indoor air will have a much lower relative
humidity, and hence potential corrosion will be minimized.
High heat sources (generating heat 100
o
F / 37
o
C or greater, such as
stove pipes, space heaters, etc.) may damage plastic components
of the water heater as well as plastic vent pipe materials. Such
damages ARE NOT covered by warranty. It is recommended to keep
a minimum clearance of 8” from high heat sources. Observe heat
source manufacturer instructions, as well as local, state, provincial,
and national codes, laws, regulations, and ordinances when installing
this water heater and related components near high heat sources.
