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).

The natural gas fired version of the water heater covered by this 

manual is certified for use without modification for altitudes up to 

10,100 feet.
For  installations  above  10,100  feet  call  the  technical  support 

phone number listed on the back cover of this manual for further 

technical assistance. Call the local gas or utility company to verify 

Btu per cubic foot content before calling for technical assistance 

and have that information available.
Note: The actual firing rate of the water heater must not exceed 

the input rating on the water heater's rating label under any 

circumstances.
Note:  Due  to  the  input  rating  reduction  at  high  altitudes,  the 

output  rating  of  the  appliance  is  also  reduced  and  should  be 

compensated for in the sizing of the equipment for applications.

See  the  Circulation  Pump  Wiring  Diagrams  (Figure  8,  Figure 

9)  in  this  manual  for  electrical  hookup  information.  Install  in 

accordance  with  the  current  edition  of  the  National  Electrical 

Code, NFPA 70 or the Canadian Electrical Code, CSA C22.1.
All-bronze circulators are recommended for used with commercial 

water heaters.
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.
