FIGURE 9. MULTI FUNCTIONAL CONTROL
13.4 MAIN BURNER PRESSURE TEST
NOTE: AIR HEATER BURNERS ARE FACTORY SET TO PROVIDE
A NOMINAL HIGH RATE OUTPUT AS DETAILED IN
PARAGRAPH 2.2
13.4.1 Referring to Table 1 and Figure 9 below, ensure that the
pressure test gauge indicates the correct burner pressure,
resetting if required as follows:
AT THE MULTIFUNCTIONAL CONTROL
i. Remove the Burner Pressure Adjust cover.
ii. Set the Burner Pressure Adjuster to provide a pressure
test gauge indication for the correct burner pressure
as detailed in Table 1.
iii. Refit the Burner Pressure Adjuster cover.
13.4.2 Apply the pressure set arrow to indicate the appropriate burner
pressure on the data badge.
13.5 EXTINGUISHING OF PILOT AND MAIN BURNERS
13.5.1 On the Multifunctional Control, rotate the OPERATING
CONTROL clockwise to the ‘

’ position and ensure that the
OPERATING CONTROL fully resets, and both the Pilot and
Main Burners are extinguished.
13.5.2 On the Multifunctional Control, remove the pressure test gauge
and refit the Outlet Pressure test point cover.
13.6 TEMPERATURE RISE CHECKS
13.6.1 Ignite the Pilot and Main Burners and allow 15 minutes for
stability before continuing.
13.6.2 Check the temperature rise across heater is between 45°C -
55°C, setting the fan speed as follows:
i. SYSTEM E-T HEATER
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.
ii BASIC HEATER
The fan speed is adjusted by selecting the fan speed at control panel (decrease voltage
selection to decrease fan speed).
NOTE: Tapping 1 = 210V, tapping 2 = 200V, tapping 3 = 190V, tapping 4 = 180V, tapping 5 = 170V.
13.7 AUTOMATIC CONTROLS CHECK
13.7.1 Ignite the Pilot and Main Burners and allow to operate for 15 minutes to ensure stability.
13.7.2 Set the TIME CONTROL to ‘
ON ’.
13.7.3 Turn the Thermista-stat or room thermostat slowly clockwise until the Main Burner ignites.
13.7.4 Ensure that the fan starts to operate after a short period, approximately 1-2 minutes.
SYSTEM E-T MODELS
13.7.5 Ensure that the fan speed increases to full speed.
13.7.6 When the temperature reaches the control setting, check that the Main Burner cycles ON and OFF,
at approximately 75 to 120 seconds.
BASIC MODELS
13.7.7 When the temperature reaches the control setting, ensure that the Main Burner extinguishes followed
by the fan switching off after a short period.
13.7.8 When the temperature falls below the control setting, ensure that the Main Burner re-ignites followed
by fan operation.
13.8 SAFETY CHECK
13.8.1 Check for gas soundness within the appliance.
13.8.2
SPILLAGE TEST
Carry out a full spillage test as follows, and ensure that the flue operates effectively with all doors
closed and any extractor fans in operation.
NOTE:
If an extractor fan is situated in an adjoining or adjacent room, carry out the spillage test with the
interconnecting doors open.
