This unit may be installed at elevations up to 10,100 ft
Note
●
(3,078 m) for use with natural gas and propane.
To use the unit at a specific altitude, the DIP Switches
should be set as described above.
High Altitude: Above 2,000 ft (610 m), the unit will de-
●
rate by 3% for each 1,000 ft (305 m) of altitude gain.
For NG, if you install the unit at above 5,400 ft (1,646
●
m), it is required to change the Gas Orifice for high
altitude. Be careful not to confuse it with the Gas
Orifice for LP.
Note that the Gas Orifice from the LP CONVERSION
●
KIT covers the boiler’s installation at an altitude of 0 to
10,100 ft.
CAUTION
Ensure that the High Altitude setting reflects the actual
location of the boiler. If not, it may cause personal injury or
malfuction of the boiler.
DANGER
When conversion is required, be sure to set the PCB DIP
●
switch 2 #1 according to the supply gas type.
For NG, use the Gas Orifice for high altitude when the boiler
●
is installed at above 5,400 ft, and be careful not to confuse it
with the Gas Orifice for LP.
For High Altitude conversion, check the DIP switches setting
●
value by altitude before setting.
Failure to properly set the DIP switches could cause carbon
●
monoxide poisoning, resulting in severe personal injury or
death.
11. Turn on the gas and water supply to the boiler.
