1.5.3.2 Burner Adjustment - The burners must be adjusted to deliver optimum flame. Adjust the
burner flame using the following procedure.
a. Ensure that the Unitrol valve knob is in the OFF position. Remove the manifold pressure
tap plug and connect an accurate pressure gauge (range of 0-16" w.c. in 0.1" increments)
or manometer.
b. Light the pilot burner (see 1.5.2) for the unit being tested and adjust the thermostat to light
the main burners.
c. The installed pressure gauge reading should be the same, ±0.1", as that marked on the data
plate inside the door. If the pressure is correct go to step e, if not, adjust the pressure.
d. To adjust the pressure, remove the regulator adjustment screw cover (see Figure 1-3). Use
a flat tip screwdriver to adjust the screw until the proper pressure is reached. Turning the
screw clockwise will increase the pressure, counterclockwise will decrease the pressure.
e. When the pressure is correct, install the regulator adjustment screw cover.
f. To remove the pressure gauge, turn gas control valve to OFF. Remove the gauge and install
the pressure tap plug.
g. Now that the pressure is set for proper operation, set the main burner flame. Unlock the air
collars by loosening the set screw for the collars. See Figure 5. Turn the Unitrol valve knob
to ON and turn thermostat to light the main burners.
h. Adjust the shape and size by raising or lowering the air collars to achieve a soft blue flame
with well defined inner cones.
i. When the flames have been properly adjusted, lock the collars in place with the set screw
provided.
