This water heater is equipped with a three prong plug. It should
only be plugged directly into a properly grounded three prong
receptacle. DO NOT remove the ground plug from the plug.
Any claims for damage or shortage in shipment must be led
immediately against the transportation company by the consignee.
This water heater provides a overheat shutdown limit. In the event
the water heater water exceeds the set point of the control limit, the
cuto will trip and the water heater will shut down. Certain local
codes require additional temperature limits. In addition, certain
types of systems may operate at temperatures below the minimum
set point of the limit provided with the water heater. Contact the
manufacturer for additional overheat controls.
NOTE: When inquiring about service or troubleshooting, reference the
model and serial numbers from the water heater rating label.
DO NOT USE THIS WATER HEATER IF ANY PART HAS BEEN
SUBMERGED IN WATER. Immediately call a qualied installer /
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.
NOTE: If the water heater is exposed to the following, do not operate.
Immediately call a qualied installer / 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 alter or modify the water heater or water heater controls.
Altering any HTP water heater with parts not manufactured by HTP
WILL INSTANTLY VOID the water heater 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.
B. 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.
C. Gas
Should overheating or gas supply fail to shut o, turn o the manual
gas control valve to the water heater.
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.
D. 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.
• 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.
• Always verify proper operation after servicing the water
heater.
NOTE: When inquiring about service or troubleshooting, reference
the model and serial numbers from the water heater rating label.
Be sure to disconnect electrical power before opening water
heater cabinet or performing service. Label all wires while
performing service to ensure proper re-wiring of the water heater.
Wiring errors can cause improper or dangerous operation. Failure
to do so could result in an electrical shock, improper water heater
operation, property damage, serious personal injury, or death.
E. Water Chemistry Requirements
Chemical imbalance of the water supply may aect eciency and
cause severe damage to the appliance and associated equipment.
Water quality must be professionally analyzed to determine
whether it is necessary to treat the water. Various solutions are
available to adjust water quality. Adverse water quality will aect
the reliability of the system. In addition, operating temperatures
above 135
o
F will accelerate the build-up of lime scale and possibly
shorten appliance service life. Failure of an appliance due to
lime scale build-up, low pH, or other chemical imbalance IS NOT
covered by the warranty.
The water must be potable, free of corrosive chemicals, sand,
dirt, and other contaminates. It is up to the installer to ensure the
water does not contain corrosive chemicals or elements that can
damage the heat exchanger. Potable water is dened as drinkable
water supplied from utility or well water in compliance with EPA
secondary maximum contaminant levels (40 CFR Part 143.3). If
the water contains contaminants higher than outlined by the EPA,
water treatment is recommended and additional, more frequent
maintenance may be required. See Table 1.
If you suspect that your water is contaminated in any way,
discontinue use of the appliance and contact an authorized
technician or licensed professional.
