6. After successful ignition the pilotstat knob (4) is then manually turned to the „ON‟
position allowing gas entry via the gas valves (2) internal main valve to the burner (11).
The burner (11) and fan (12) will now operate on full flame and full speed and both the
internal pilot valve solenoid and internal main valve solenoid are held open by the
voltage generated by thermopile 1 (8) and thermopile 2 (9), provided the blocked flue
switch (10) remains closed.
7. After successful ignition and operation in „LOCAL‟ mode, the LOCAL/REMOTE selector
switch (3) may be set on „REMOTE‟ allowing burner flame and fan speed to be adjusted
manually or automatically by the remote controller (13). The gas valve (2) has an
antenna (14) which receives the remote controller‟s (13) signals.
8. The gas valve (2) modulating motor (15) responds to the remote controller (13) signal
by opening or closing in seven stages of modulation (0 = off & 6 = full flame) regulating
the gas supply to the burner (11). Likewise the gas valve (2) will vary the voltage output
to the fan motor (12) controlling the fan speed in response to the remote controller (13)
signal. Refer to „Remote Controller Operation‟ on page 12 for information on operating
the remote controller.
9. The pilot and burner will turn off if any of the following circumstances occur:
The pilotstat knob (3) is manually rotated to the „OFF‟ position.
Thermopile 1 (8) generates less than 500mVDC.
Thermopile 2 (9) generates less than 280mVDC.
The blocked flue switch (10) open circuits. This will occur at a temperature of 132ºC
for the LHEC30 and 218ºC for the RFSDV34.
