Adjustment, Start &
Stop
In this section you will find instructions on how to adjust a
system, and how to start and stop a system.
■ Do not bypass any safety feature. You can cause
fires and explosions.

Adjustment Procedure

Step 1: Reset the System

Figure 4.1. Reset the System
1. Close the automatic gas valves and gas cocks.
2. Fully open the manual air butterfly valve at each
burner.
a. Drive the automatic zone air control valve to high
fire.
b. Adjust the automatic zone air control valve so that
it is fully open.
3. Start the blower.
NOTICE
■ Make sure that the blower rotates in the correct
direction. If incorrect, have a qualified electrician
rewire the blower to reverse its rotation.

Step 2: Set High Fire Air

NOTE: The following steps apply to an ambient air
system with orifice plates installed.
1. Make sure that the system is at high fire.
2. Set high fire air.

DANGER
Use the air curve of the datasheet for your particular
burner to find the air pressure differential that you need
at high fire. This is now your target value for high fire.
NOTE: A pressure tap is open when the screw inside
the tap is unscrewed approximately half a turn.
Figure 4.2. Set High Fire Air
a. Make sure that pressure tap A and pressure tap B
of the burner are open. (Open the internal screw
1/2 turn.)
b. Connect the manometer to tap A and tap B of the
burner (across the air orifice). Make sure that the
hose completely covers the side vents on pressure
tap.
c. Adjust the manual zone air butterfly valve until the
high fire air pressure differential is at the target
value. Make sure that the manual butterfly valves at
every burner are fully open.
d. Measure and note the air pressure differential for all
other burners in the zone.
e. If all the measured differential pressures are within
0.3" w.c. of each other, then proceed to the next
section. If the variation is greater than 0.3" w.c.,
then it will be necessary to adjust the manual air
butterfly valve at each burner to improve the
balance.
