12. Remove the Gas Orifice, ensure that the gasket
is properly seated inside the port, and then

gas. Ensure that the Orifice is properly seated on
the gasket inside the port before proceeding to
the next step.

13. Replace the gas inlet pipe to its original position
and use all screws to secure all connections.
Do not overtighten as this may

damage or crack the components.
14. Set the PCB DIP switch to change the gas type.
For LP, set DIP SW2 (Set of 8 Switches) #1 to ON.
For NG, set DIP SW2 (Set of 8 Switches) #1 to OFF.
WARNING
Ensure that you have turned off the power to

This unit may be installed at elevations
Note
●
up to 10,100 ft (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 and 4%
de-rate for propane gas.
For Natural Gas, 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 Propane.
Note that the Gas Orifice from the

installation at an altitude of 0 to 10,100 ft.
WARNING
Ensure that the High Altitude setting reflects the
actual location of the boiler. If not, it may cause
personal injury or malfunction of the boiler.
