COMPLETING HEATER INSTALLATION
COMMISSIONING THE APPLIANCE
Step 9.
To check and set burner pressures:
1. Refer to the data plate located on the front left panel of
the heater engine for correct gas pressure settings.
2. Using a suitable screw driver loosen the captive
Appliance Test Point Pressure screw (ATPP)
and fit
the manometer, (an electronic manometer is
recommended). Refer images for ATPP location.
3. Remove the dust cap
from the regulator adjusting
nut
and
screw .
4. High Pressure Setting:
Turn the appliance 'ON' and set the heater to the
highest setting, see “TO TURN YOUR HEATER ON” on
page 9. Using an appropriate screw driver hold the low
pressure adjusting screw
stationary while adjusting
the high pressure setting, nut
with a 10 mm
spanner. Turning the nut clockwise will increase the
outlet pressure whilst turning the nut anti-clockwise will
decrease the outlet pressure.
5. Low Pressure Setting:
Disconnect the power to the Gas Control Valve (GCV)
by separating the connector
for the power supply
(yellow wires). The GCV will automatically default to
'Low Pressure' operation. Using a 10 mm spanner hold
the high pressure adjusting nut
stationary while
adjusting the low pressure setting, screw
with an
appropriate screw driver. Turning the screw clockwise
will increase the outlet pressure whilst turning the screw
anti-clockwise will decrease the outlet pressure.
6. Replace the dust cap
after pressure adjustments.
7. Reconnect the power to the GCV by rejoining the
connector
(yellow
wires).
8. After confirming the correct pressures, turn the
appliance 'OFF', remove manometer and tighten the
ATPP sealing screw
and leak test.
9. Turn the appliance 'ON' and 'OFF' a few times to
confirm correct ignition and operation.
10. During the initial burn in period, some smoke and smell
may be emitted. The appliance should be run on the
high setting in a well ventilated room until these
dissipate.
11. Check the flame pattern, see '“ABNORMAL FLAME
PATTERN” on page 48.
The gas type codes and gas pressures for this
appliance
MUST BE
checked and set in
accordance with these instructions when the
appliance is installed,
OR
after the
replacement of any component or reassembly
after service.
To ensure the correct operation of the GCV it
is necessary that the dust cap
is returned
to its original location.
