GENERAL SAFETY INFORMATION GENERAL SAFETY INFORMATION
PRECAUTIONS
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN
EXPOSED TO FLOODING OR WATER DAMAGE. Immediately call
a qualified service technician to inspect the water heater and to make
a determination on what steps should be taken next.
If the unit is exposed to the following, do not operate heater until all
corrective steps have been made by a qualified service technician.
1.
External fire.
2. Damage.
3. Firing without water.
LIMITING THE RISK OF SCALDING
For a variety of reasons, water heaters can produce water that is
much hotter than its temperature setting. Take precautions to prevent
this higher temperature water from reaching the water fixtures.
Burn Hazard
To reduce the risk of unusually hot
water reaching the fixtures in the
house, install thermostatic mixing
valves at each point of use.
According to a national standard ( ASSE 1070 ) and many local plumbing
codes, the water heater’s gas control valve should not be used as
the sole means to regulate water temperature and avoid scalds.
A properly adjusted thermostatic mixing valve at each point of use
allows you to set the tank temperature to a higher setting without
increasing risk of scalds. A higher temperature setting allows the
tank to provide much more hot water and can help provide proper
water temperatures for appliances such as dishwashers and washing
machines.
Higher tank temperatures (140°F) also kill bacteria that cause a
condition known as “smelly water” and can reduce the levels of
bacteria that cause water-borne diseases.
GROUNDING INSTRUCTIONS
This water heater must be grounded in accordance with the Canadian
Electrical Code and/or local codes. These must be followed in all cases.
Failure to ground this water heater properly may also cause erratic
control system operation.
This water heater must be connected to a grounded permanent
wiring system; or an equipment grounding conductor must be
run with the circuit conductors and connected to the equipment
grounding terminal or lead on the water heater.
HYDROGEN GAS FLAMMABLE
Explosion Hazard
Flammable hydrogen gases
may be present.
Keep all ignition sources away
from faucet when turning on
hot water.
Hydrogen gas can be produced in a hot water system served
by this water heater that has not been used for a long period of
time (generally two weeks or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under these conditions, it is
recommended that a hot water faucet served by this water heater
be opened for several minutes before using any electrical appliance
connected to the hot water system. If hydrogen is present there will
probably be an unusual sound such as air escaping through the pipe
as the water begins to flow.
THERE SHOULD BE NO SMOKING
OR OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPEN .
Verify the power to the water heater is turned off before performing any service procedures. The Enable/
Disable switch on front panel disables the 24 volt gas valve. Electrical supply must be turned off at circuit
breaker serving water heater.
Read and understand this instruction
manual and the safety messages
herein before installing, operating or
servicing this water heater.
Failure to follow these instructions and
safety messages could result in death
or serious injury.
This manual must remain with the
water heater.
Water temperature over 125°F (52°C)
can cause severe burns instantly
resulting in severe injury or death.
Children, the elderly, and the physically
or mentally disabled are at highest risk
for scald injury.
Feel water before bathing or showering.
Temperature limiting devices such as mixing
valves must be installed at each point of use
when required by codes and to ensure safe
temperatures at fixtures.
Read instruction manual for safe
temperature setting.
