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 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.
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.

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.
A. Locating the Water Heater
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.
Locate the water heater where any leakage from the relief valve,
related piping, tank, or connections will not result in damage to
surrounding areas or lower floors of the building. The water heater
should be located near a floor drain or installed in a drain pan. HTP
WILL NOT be held liable for leakage damages.
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.
