Adjustment - Honeywell V4336 Bedienungsanleitung

ADJUSTMENT

IMPORTANT
Adjustments should be made by qualified persons
only.
If the appliance manufacturer supplies checkout and/
or service and maintenance instructions, carefully fol-
low 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 High-Low regulator is
operated a few times to ensure correct setting.
It should be prevented, that High-Low regulator is
exposed to unneccessary forces because of wiring.
Cap has to be removed by putting a small screw
driver in one of the slots and lifting the cap carefully
while at the same time supporting the cap opposite to
the screw driver, (see fig. 4. page 13).
WARNING
Maximum pressure setting must first be adjusted then
minimum pressure setting can be adjusted.
Any adjustment of maximum pressure setting influ-
ences minimum pressure setting.
Never adjust the maximum setting above the range
specified
Adjusting maximum pressure setting (see fig. 1. page 2)
• 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).
• Energize High-Low regulator, set gas control in operation
and wait until an outlet pressure is recorded on pressure
gauge.
• Use a 8 mm wrench to turn adjustment screw for maximum
pressure setting clockwise to increase or counter-clockwise
to decrease pressure, until desired maximum burner
pressure is obtained.
• Check maximum pressure setting after several times.
Adjusting minimum pressure setting (see fig.1. page 2)
• 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 High-Low regulator.
• Set gas control in operation and wait until an outlet
pressure is recorded on the pressure gauge.
• When minimum pressure setting needs adjustment, then
use a 3.5 mm screw driver to turn adjustment screw for
minimum pressure setting clockwise to increase or counter-
clockwise to decrease pressure, until desired minimum
burner pressure is obtained.
• Wire High-Low regulator coil in circuit.
• Check maximum pressure setting and re-adjust if
necessary. Check minimum pressure setting again.
When High and Low pressure settings are correct, replace cap
and connect pressure feedback connection (if applicable).

After any adjustment, set appliance in operation and observe
through several complete cycles to ensure that burner system
components function correctly.
