to individual controller operating manual.)
(e) Select 'on' position for heater on/standby
switch.
(f) Check for the following burner sequence

(h) Attach oil manifold (bleed screw and
pressure gauge)
(i) Open oil supply valves and bleed air from
pipe work and adjust burner oil pressure as
per detailed in burner manual (section B)
(j) Repeat steps 4.1 q, and 4.2 c,e,f.

Note
It is strongly recommended that the separate
manual concerning the operational details of
the burner supplied with the heater as part
of the information package is studied prior to
commissioning.
Time intervals within the ignition sequence
will vary slightly from one model to another.
Warning
If burner ignition is not satisfactorily
accomplished, commissioning must not
proceed until the reason or fault has been
identified and rectified, if necessary by
reference to the separate burner information
or to section 6 of this manual.
(k) Repeat steps 4.2 c,a,
(l) Repeat steps 4.2 d,e,f, allowing the
heater to reach thermal equilibrium.
(m) Adjust room thermostat to its highest
setting, and allow the heater to continue to
fire.
(n) Gradually reduce the temperature setting
on the room thermostat until the burner
shuts down, (@ < ambient and then
gradually increase the temperature setting
on the thermostat until heat is called for, (@
> ambient) and the burner automatically re-
fires.
(o) Re-set time clock to a minimum off
period, checking that the burner shuts down,
and then automatically re-lights once the
minimum off period has elapsed (Separate
information on the time clock is contained
within the information package supplied with
the heater).
(p) Check limit stat by tripping the fan motor
overload re-set by pressing the reset button
on the overload, located on the heater
electrical panel. The time between the fan
stopping and burner shut down should be
noted (90 seconds max), once the burner
has shut down the overload on the motor
should be released.
(q) Undertake flue gas analysis using
approved and calibrated analysing
equipment recording data on the
commissioning card, ie, CO, CO
2
, net and
gross flue temperatures.
Record burner oil pump pressure, ambient
temperature, barometric pressure, and
smoke reading (0 - 1 Baccarach scale).
Note (i)
The burner air and oil pressure settings
should be only very finely adjusted to
achieve a CO
2
reading of 12.5% (+/- 0.5%).
Note (ii)
The gross efficiency must be approximately
80 % sample taken at 1m above the flue
spigot point.
Note (iii)
All Cabinet Heaters are test fired and pre-
commissioned as part of the manufacturing
process, if however, during on site
commissioning the data are found to be not
in accordance with the manufacturers data,
then the following action is recommended.
* Re-check all readings and calculations.
* Adjust burner as per manufacturers
instructions.
