3. Commissioning
3.1 Tools Required.
The following tools on the right are advis-
able to complete the tasks laid out within
this manual.
Note: Suitable alternative tools may be used.
Leather Faced Gloves 3mm and 4mm Allen Keys
Pozidrive Screwdrivers
Adjustable Spanner or 22mm,
26mm and 27mm Spanners
Small Flat Head Screwdrivers
Manometer
3.2 Balance the herringbone system
WARNING
The appliances should be commissioned
by a competent/qualified engineer.
Isolate each heater unit by unplugging
the electrical connector and closing the
gas isolating valve.
CAUTION
When all heaters have been installed the
vacuum settings must be finally balanced
in the hot condition.
Note: Before starting the heating system it is essential
to perform the preliminary balancing of the vacuum
level at each burner unit by setting the cold damper
pressures (see Table 12).
Adjust the damper at the exit of each heater
using a 3mm allen key in the damper blade
securing screw. Once the system damper
has been adjusted to give the cold herring-
bone pressure (within 0.5 mbar of the stated
value) at the heater damper furthest from
the fan, start all burners up and allow them
to run for at least 20 minutes. Observing
the vacuum reading using a manometer
connected to the vacuum test point (see
Figure 51). Each damper should be set at
a hot condition, as shown in Table 10 for
the appropriate size of heater and model. If
the hot vacuum is too low with the heater
damper fully open, the system damper
will need to be adjusted to provide more
system vacuum.

3.3 Balancing a DLE System
WARNING
Isolate each heater unit by unplugging
the electrical connector and closing the
gas isolating valve.
Note: Before attempting to start up the heating system
it is essential to perform the preliminary balancing of the
vacuum level at each burner unit.
CAUTION
Important. When all the heaters have
been installed the vacuum settings must
be finally balanced in the hot condition.
As with a Herringbone system above, once
the cold damper pressures have been set,
start both burners up and allow them to run
for at least 20 minutes.
Adjust the damper on the condensate box
using a 4mm Allen key in the damper blade
securing screw.
Observing the vacuum reading using a
manometer connected to the vacuum test
point (see Figure 52). Each damper should
be readjusted and set at a hot condition
reading as shown in Table 10 for the appro-
priate size of heater and model.
