Breathing Hazard - Carbon Monoxide Gas
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
Under no circumstances should
the input exceed the rate shown
on the water heater’s rating label.
Overfiring could result in damage to
the water heater and sooting.
Gas and carbon monoxide detectors
are available.

You should contact your gas supplier for any specific changes
which may be required in your area.
As elevation above sea level is increased, there is less oxygen
per cubic foot of air. Therefore, the heater input rate should be
reduced at high altitudes for satisfactory operation with the
reduced oxygen supply. failure to make this reduction would
result in an over firing of the heater causing sooting, poor
combustion and/or unsatisfactory heater performance.
ratings specified by manufacturers for most appliances apply
for elevations up to 2000 feet (610m). for elevations above 2000
feet (610), ratings must be reduced at the rate of 4% for each
1000 feet (305m) above sea level. for example, if a heater is
rated at 78,000 Btuh (22.9 Kwh) at sea level, to rate the heater
at 4000 feet (1219m), you subtract 4 (once for each thousand
feet) x.04 (4% input reduction) x 78,000 (original rating) from the
original rating.
Therefore, to calculate the input rating at 4,000 feet (1219m):
4 x .04 x 78,000 = 12,480 Btuh (3.7 Kwh), 78,000 (22.9 Kwh) -
12,480 (3.7 Kwh) = 65,520 Btuh (19.2 Kwh). At 6000 feet (1829m)
the correct input rating should be 59,280 Btuh (17.4 Kwh).
Some circulating pumps are manufactured with sealed bearings
and do not require further lubrication. Some circulating pumps
must be periodically oiled. refer to the pump manufacturer’s
instructions for lubrication requirements.

Fire and Explosion Hazard
Gas and carbon monoxide detectors are
available.
Overfiring could result in fire or
explosion.
Under no circumstances should the
input exceed the rate shown on the
water heater’s rating label.
