After any adjustment, set appliance in
operation and observe through several
complete cycles to ensure that burner
system components function correctly.
IMPORTANT
Adjustments should be
made by qualified
persons only.
If the appliance
manufacturer supplies
checkout and/or service
and maintenance
instructions, carefully
follow them. If such instructions are not
provided, then follow the procedure as
outlined below.
Allow time for pressure to stabilize before
making adjustments.
It is recommended that the Modureg is
operated a few times to ensure correct
setting.
Cap must be removed before any
adjustment can be made. Cap can be
removed by firstly removing the small
retaining screw and lifting the cap carefully.
Take care that after any adjustment cap and
O- ring are mounted (if applicable).
The minimum pressure setting must first
be adjusted to ensure that burner will
safely light up, then maximum pressure
setting can be adjusted.
Any adjustment of minimum pressure
setting influences the maximum pressure
setting.
Adjusting minimum pressure setting
Disconnect pressure feedback
connection (if applicable).
Connect a suitable pressure gauge to
pipe line or to outlet pressure tap of gas
control concerned, to measure burner
pressure (measuring point must be as
near to burner as possible).
Disconnect electrical connection to
Modureg.
Energize operator, set control in
operation and wait until an outlet
pressure is recorded on pressure gauge.
If minimum pressure setting needs
adjustment turn the adjustment for
minimum pressure setting clockwise for
increasing or counter-clockwise for
decreasing pressure until the desired
minimum outlet pressure is obtained.
Check that main burner lights easily and
reliably at minimum pressure.
Check maximum pressure setting and
readjust if necessary.
Mount cap and “O” ring and reconnect
pressure feedback connection (if
applicable).
Adjusting maximum pressure setting
Disconnect pressure feedback
connection (if applicable).
Connect a suitable pressure gauge to
pipe line or to outlet pressure tap of gas
control concerned, to measure burner
pressure (measuring point must be as
near to burner as possible).
Disconnect electrical connection of
Modureg.
Energize operator, set control in
operation and wait until an outlet
pressure is recorded on pressure gauge.
Push the shaft gently downwards to the
