NOTE: If the water heater is exposed to the following, do not
operate. Immediately call a qualied service technician.
1. Fire
2. Damage
3. Water
Failure to follow this information could result in property damage,
severe personal injury, or death.
DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN
SUBMERGED IN WATER. Immediately call a qualied service
technician. The water heater MUST BE replaced if it has been
submerged. Attempting to operate a water heater that has been
submerged could create numerous harmful conditions, such as
a potential gas leakage causing a re and/or explosion, or the
release of mold, bacteria, or other harmful particulates into the
air. Operating a previously submerged water heater could result in
property damage, severe personal injury, or death.
NOTE: Water heater damage due to ood or submersion is
considered an Act of God, and IS NOT covered under product
warranty.
This water heater has been designed to heat potable water ONLY.
Using this water heater to heat non-potable uid WILL VOID
product warranty, and could result in property damage, personal
injury, or death.
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.
A. Improper Combustion
Do not obstruct the ow of combustion and ventilating air.
Adequate air is necessary for safe operation. Failure to keep the
exhaust vent and combustion air intake clear of ice, snow, or other
debris could result in property damage, serious personal injury,
or death.
B. Gas
Should overheating or gas supply fail to shut o, turn o the manual
gas control valve to the water heater.
C. When Servicing the Water Heating System
To avoid electric shock, disconnect electrical supply before
performing maintenance.
NOTE: When inquiring about service or troubleshooting, reference
the model and serial numbers from the water heater rating label.
D. 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.
E. Freeze Protection
NOTE: Consider piping and installation when determining heater
location.
Failure of the water heater due to freeze related damage IS NOT
covered by product warranty.
Be sure to disconnect electrical power before performing service.
Failure to do so could result in electrical shock, property damage,
serious personal injury, or death.
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 led immediately against the
transportation company by the consignee.
G. 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.
F. High Elevation Installations
Natural gas at high elevation might contain less heating value than
typical 1,000 BTU/cu ft and therefore can cause improper air / gas
mix leading to improper combustion. For natural gas installations
above 3,000 ft, call your gas provider to determine the heating value
of the supplied natural gas.
To avoid severe burns, allow water heater and associated equipment
to cool before servicing.
