Installer - Read all instructions in this manual before installing.
Perform steps in the given order.
User - This manual is for use only by a qualified heating installer
/ service technician. Have this water heater serviced / inspected
annually by a qualified service technician.
FAILURE TO ADHERE TO THE GUIDELINES ON THIS PAGE
CAN RESULT IN SUBSTANTIAL PROPERTY DAMAGE, SEVERE
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 qualified serviceman:
1. Fire
2. Damage
3. Water
Failure to follow this information could result in property damage,
severe personal injury, or death.
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.
UNCRATING THE WATER HEATER - Any claims for damage or
shortage in shipment must be filed 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.
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.
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.
Part 1 - General Safety Information
This water heater is approved for indoor installation only and is
not intended for use as a pool heater. Clearance to combustible
materials: 0” top, bottom, sides, and back. Heater must have room
for service: 24” front, 6” top, and 0” sides are recommended service
clearances. (A combustible door or removable panel is acceptable
front clearance.) This water heater has been approved for closet
installation and installation on combustible flooring. Do not install
directly on carpeting. Install the water heater in a location where
temperature and pressure relief valve discharge or a leak will not
result in damage to the surrounding area.
NOTE: Obey all local codes. Obtain all applicable permits before
installing the water heater.
NOTE: Install all system components and piping in such a manner
that does not reduce the performance of any fire rated assembly.
