A. When Servicing the Water Heating System
To avoid electric shock, disconnect electrical supply before
performing maintenance.
To avoid severe burns, allow water heater and associated
equipment to cool before servicing.
B. Heater Water
Do not use petroleum-based cleaning or sealing compounds in
a water heating system. Gaskets and seals in the system may
be damaged. This can result in substantial property damage.
Do not use “homemade cures” or “patent medicines”.
Damage to the water heater, substantial property damage,
and/or serious personal injury may result.
NOTICE FOR SINGLE-WALL HEAT EXCHANGER MODELS
Per the Uniform Plumbing Code:
Single-wall heat exchangers are permitted if they satisfy all of
the following requirements:
The heat exchanger medium is potable water or contains only
substances which are recognized as safe by the US Food and
Drug Administration (FDA).
The pressure of the heat exchanger medium is maintained
less than the normal minimum operating pressure of the
potable water system (steam systems must comply with this
statement).
The equipment is permanently labeled to indicate that only
additives recognized as safe by the FDA shall be used as the
heat transfer medium.
Other heat exchanger designs may be permitted where
approved by the AHJ.
C. Freeze Protection
NOTE: Consider piping and installation when determining
heater location. Place the water heater as close to the boiler as
possible, in a location not prone to freezing.
Failure of the water heater due to freeze related damage IS NOT
covered by product warranty.
In water heaters with single wall heat exchangers, the heat
transfer uid must be water or nontoxic food grade glycol, FDA
rated “generally recognized as safe” (GRAS) and having a toxicity
rating or class of 1, as listed in Clinical Toxicology of Commercial
Products, 5th edition. Ensure the system is permanently labeled
to indicate any additives used in the heat transfer uid.
NEVER use any toxic chemical, including automotive, standard
glycol antifreeze, or ethylene glycol made for hydronic (non-
potable) systems. These chemicals can attack gaskets and seals
in water systems, are poisonous if consumed, and can cause
personal injury or death.
NOTE: If the heater is exposed to the following, do not
operate until all corrective steps have been made by a
qualied serviceman:
1. Fire
2. Damage
3. Water
Failure to follow this information could result in property
damage, severe personal injury, or death.
UNCRATING THE WATER HEATER - Any claims for damage
or shortage in shipment must be led immediately against
the transportation company by the consignee.
Do not use this water heater for anything other than its
intended purpose (as described in this manual). Doing so could
result in property damage and WILL VOID product warranty.
High heat sources (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.
D. Water Temperature Adjustment
If the water heater is going to have a set temperature above
120
o
F, you must use an ASSE 1017 rated mixing valve to avoid
severe burns or death from scalding temperatures.
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.
Approximate Time / Temperature Relationships in Scalds
120
o
F More than 5 minutes
125
o
F 1 1/2 to 2 minutes
130
o
F About 30 seconds
135
o
F About 10 seconds
140
o
F Less than 5 seconds
145
o
F Less than 3 seconds
150
o
F About 1 1/2 seconds
155
o
F About 1 second

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.
