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.
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.
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.
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
fluid 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 fluid.
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.
UNCRATING THE WATER HEATER
- Any claims for damage or
shortage in shipment must be filed immediately against the trans-
portation company by the consignee.
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.

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.
NOTE:
A drain valve is included with the water heater.
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.
DO NOT use this indirect water heater in steam applications.
Doing so will result in damage to the water heater. Such damages
ARE NOT covered by warranty.
A. Locating the Water Heater
High heat sources (generating heat 100
o
F / 37
o
C or greater, such
as boiler flue 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.
This water heater is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by warranty.
