3.2 Commissioning - Ignition

CAUTION

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

Do not proceed with commissioning unless all the criteria
detailed within sections 3.0 and 3.1

have been satisfied.

(a) Ensure the electrical supply is turned off.
(b) Ensure that the Oil supply is turned off.
(c) Turn on main electrical supply.

(d) Enable burner via controller by selecting ‘Heat’ (Relay 2); ‘Heat On’; ‘Heat/Auto’. *

(* dependent on control type supplied. Refer to individual controller operating manual.)

(e) Select ‘on’ position for heater on/standby switch.
(f) Check for the following burner sequence on the right
(g) Set heater on/standby switch to standby position
(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 3.2 c, e, f

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 3.2 c,a,
(l) Repeat steps 3.2 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, CO2,

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 CO2 reading of 12.5% (+/-

0.5%).

Note (ii)

The gross efficiency must be approximately 80% sample taken at 1m above the flue spigot point.
