TWO STAGE REGULATOR ADJUSTMENT
NOTE:
Check the inlet pressure before adjusting the
pressure regulator.
Two-stage VR8215 requires that you check and adjust
both high and low pressure regulator settings. Adjust
high fire before adjusting low fire. Two-stage
appliance operating sequences vary. Consult the
appliance manufacturer instructions for the specific
operating sequence and regulator adjustment
procedure for the appliance in which the control was
installed.
1.
Consult the appliance manufacturer's instruc-
tions to obtain the high and low fire regulator
pressure settings.
2.
Install the regulator spring and regulator adjust-
ment as per the conversion instructions above.
3.
Set the appliance to operate on high fire.
4.
With main burner operating on high fire, cali-
brate the high fire setting using the meter clock-
ing method or using a manometer connected to
the outlet pressure tap on the control.
a. Adjust the high pressure regulator to match
the appliance rating.
b. See Table 6 for the adjustment range of the
gas valve. The appliance requirements
should be within this range.
c. Using the conversion tool, turn the Hi adjust-
ment 7/16 Hex clockwise
to increase
or counterclockwise
to decrease the
gas pressure to the burner.
5.
After high pressure has been calibrated, use the
same measurement method to calibrate the low
stage. Two-stage appliance operating
sequences vary. Consult the appliance
manufacturer instructions for the specific
operating sequence and for instructions on how
to prevent the control from moving to high stage
while calibrating the low pressure regulator
setting.
6.
With the main burner operating on low fire, cali-
brate the low fire regulator setting using the
same measurement method used to calibrate
high stage. See Fig. 9.
a. Adjust the low pressure regulator to match
the appliance rating.
b. See Table 6 for the adjustment range of the
gas valve. The appliance requirements
should be within this range.
c. Using conversion tool, turn the Lo adjust-
ment 3/32 allen screw clockwise
to
increase or counterclockwise
to
decrease the gas pressureto the burner. See
Fig. 9.
7.
Once high and low pressure regulator settings
have been calibrated and verified, reinstall the
regulator cover.
8.
If the desired outlet pressure or flow rate cannot
be achieved by adjusting the gas control, check
the gas control inlet pressure using a manome-
ter at the inlet pressure tap of the gas control.
See Fig. 8. If the inlet pressure is in the nominal
range (see Table 6), replace the gas control. Oth-
erwise, take the necessary steps to provide
proper gas pressure to the control.
9.
Replace pressure tap plugs.
10.
Mount conversion label on the gas control.
11.
Leak test the gas valve. See “Perform Gas Leak
Test” on page 5.
