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. 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.
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.
C. 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.
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.
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.
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.
D. Water Temperature Adjustment
The water heater thermostat has been set at a temperature equal to or below 131
o
F (55
o
C). See Figure 1. If the
water heater is going to have a set temperature above 120
o
F, it is recommended to use an ASSE 1017 rated
mixing valve to avoid severe burns or death from scalding temperatures.

NOTE:
After adjusting the water temperature at
the thermostat, use a thermometer to measure
the water temperature at a hot water outlet in
the structure. The recommended temperature
setting is 118
o
F.
If the ambient temperature falls below 32
o
F (0
o
C), protect the heater from potential damage by shutting off
power to the unit by means of the dedicated circuit breaker on the main electrical panel. Open a faucet slightly
to cause water to fl ow continuously through the device at a very low rate, without heating. Restore power to the
unit when temperature conditions allow.
If the water freezes inside the unit, it can cause damage that is not covered by warranty. If you suspect water has
frozen within the unit, do not turn it on until you are certain the frozen water has melted and there are no leaks in
the unit. It is recommended to contact a qualifi ed electrician or customer service in this situation.
