With the appliance firing at high fire check the manifold pressure at the discharge of the
High-End Gas Valve
and compare it to the
manifold pressure provided on the rating plate.
When the correct combustion values are achieved replace the cap back on to the gas valve.

After adjusting the screw wait a moment for the combustion levels to stabilize before attempting to make any further adjustments. Continue
this procedure until combustion levels are satisfied.
When the correct combustion values are achieved replace the screw cap back on to the gas valve.
To adjust the high fire setting of the
Low-End Valve
(AV1000
– 4000)
The high fire setting of the
Low-End Gas Valve
must be set at a point just before the Siemens gas valve is activated. This will vary from
model to model and the installer will need to monitor at which point on the VFD that the transition occurs. It is advised to set the
High-
End Gas Valve
at 2 Hz below where the transition occurs. This transition has been set and tested at the factory and should normally not
require adjustment
