Mounting the High Altitude Bypass

The High Altitude Bypass is to modify the diesel fuel amount 

when the RV is at an elevation of over 5,000 ft.
•  Reference the following illustrations below for mounting 

the High Altitude Assembly to the burner.

•  Fuel pump is required to be installed horizontally.
•  It is recommended to use a minimum of three mounting 

holes.

•  Do NOT mount the fuel pump higher than the fuel inlet on 

the burner (see Figure 7 on Page 8 and the Fuel System 

section pages 40-44 for reference).
