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

replacement of burner orifices in accordance with current

edition of the National Fuel Gas Code (ANSI Z223.1). For

Canadian installations consult Canadian Installations Code

CAN/CSA B149.1. Failure to replace orifices will result in

improper and inefficient operation of the water heater resulting

in the production of increased levels of carbon monoxide gas

in excess of safe limits which could result in serious personal

injury or death.

You should contact your gas supplier for any specific changes

which may be required in your area.

As the 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).

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.
