5.6 Adjusting the Gas Train
The burner is test-run with propane prior to delivery.
During operation, the safety valve (1) must be fully open.
When adjusting Stage 1 on the burner, valve 2 must
be opened using the adjustment screw (c). When this is
screwed in, the flow of gas to the burner increases by
lifting the valve. During initial setting, the valve must have
been lifted by the adjustment screw after 1-2 turns. This
valve is always open and this opening is what determines
the minimum load.
When adjusting Stage 2 is done using the adjustment
screw (a) which controls the opening of valve 1.
At start-up, the safety valve opens and valve 1 gas flows
through valve 2, which was opened using adjustment

screw C. The burner now receives gas for the minimum
load. Increase the load to Stage 2 and set the output on
the burner.
Output is adjusted at Stage 2 by opening valve 1 using
adjustment screw A and adjusting the gas pressure on
pressure regulator screw B. The air damper must also
be adjusted to ensure that the correct volume of air is
obtained. Once the correct output and pressure are set
in Stage 2, move on to Stage 1. Stage 1 is now adjusted
using adjustment screw C to ensure that the correct
volume of gas is obtained. Adjust the air damper for
correct combustion.
