MAIN BURNER PRESSURE TEST:

NOTE: AIR HEATER BURNERS ARE FACTORY SET TO PROVIDE A NOMINAL HIGH PRESSURE OUTPUT AS
DETAILED IN SUB PARA 1.2

6.4.1

Referring to Table 2 and Fig. 4 below, ensure that the pressure test gauge indicates the correct burner pressure,
resetting if required as follows:
a.

At the Multifunctional control:
i.

Remove the Burner Pressure Adjuster cover.

ii.

Set the Burner Pressure Adjuster to provide a pressure test gauge indication for the correct burner
pressure as detailed in Table 2.

iii.

Refit the Burner Pressure Adjuster cover.

6.4.2

Apply the pressure set arrow to indicate the appropriate burner pressure on the data badge.

6.5

EXTINGUISHING OF PILOT AND MAIN BURNERS:

6.5.1

On the Multifunctional control, rotate the OPERATING CONTROL clockwise  to the ‘

l

’  position and ensure that

the OPERATING CONTROL fully resets, and both the Pilot and Main Burners are extinguished.

6.5.2

On the Multifunctional control, remove the pressure test gauge and refit the Outlet Pressure test point cover.

6.6

TEMPERATURE RISE CHECKS:

6.6.1

Ignite Pilot and Main burners and allow 15 minutes for stability before continuing.

6.6.2

Check temperature rise across heater is between 45

o

C - 55

o

C, setting fan speed as follows:

i.

SYSTEM E-T heaters:  System E-T provides a fan speed corresponding to the above temperature rise, if
the appliance is to be set to operate at the minimum rate and the ducting has been sized accordingly, set
the ‘RATE SWITCH’ to ‘

MIN

’, thus reducing the fan speed.
