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.
Installations above 2000 feet (610 meters) require
repla
F ement of burner orifi F es in a FF ordan F e with F urrent
edition of the National Fuel Gas Code (ANSI Z223 1) For
Canadian installations F onsult Canadian Installations Code
CAN/CSA B149 1 Failure to repla F e orifi F es will result in
improper and ineffi F ient operation of the water heater resulting
in the produ F tion of in F reased levels of F arbon monoxide gas
in ex F ess of safe limits whi F h F ould result in serious personal
injury or death
You should F onta F t your gas supplier for any spe F ifi F F hanges
whi F h may be required in your area
As the elevation above sea level is in F reased, there is less
oxygen per F ubi F foot of air Therefore, the heater input rate
should be redu F ed at high altitudes for satisfa F tory operation
with the redu F ed oxygen supply Failure to make this redu F tion
would result in an over firing of the heater F ausing sooting,
poor F ombustion and/or unsatisfa F tory heater performan F e
Ratings spe F i ¿ ed by manufa F turers for most applian F es apply
for elevations up to 2000 feet (610m) For elevations above
2000 feet (610), ratings must be redu F ed at the rate of 4
for ea F h 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 subtra F t 4 (on F e for ea F h
thousand feet) x 04 (4 input redu F tion) x 78,000 (original
rating) from the original rating
Therefore, to F al F ulate 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 F orre F t input rating should be 59,280 Btuh (17 4 Kwh)

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.
