Pre-Purge Mode
For use with a power vent only.
Follow these instructions to activate the
power vent pre-purge feature. This feature
must be activated for the safe operation of
an appliance equipped with a power vent.
Switching to the power vent pre-purge
mode:
1. To turn feature ON and OFF, press and
hold the STANDING PILOT button on the
wallswitch for 10 seconds (Fig.#29a).
2. When the feature is activated, the green
LED should flash (0.5 seconds ON, 0.5
seconds OFF) 5 times.
3. When the feature is deactivated, the red
LED should flash (0.5 seconds ON, 0.5
seconds OFF) 5 times.
4. When the pre-purge feature is ON:
• The low battery backup warning feature
will be disabled and the LED will not
flash to indicate low battery (The battery
backup must be removed when using a
power vent).
• The Standing Pilot feature will be de-
activated (feature not available when
Power Vent Pre-Purge Mode is active).
• Upon receiving any ON command, the
power vent output will close immediately,
but the ignition cycle will NOT begin for 10
seconds (pre-purge).
This means that
the module WILL NOT emit a spark and
WILL NOT energize the pilot operator
and the 60 second ignition trial period
WILL NOT begin until the 10 second
pre-purge delay is complete.
• Upon receiving any ON command, the
green LED will flash (0.5 seconds ON,
0.5 seconds OFF) for 10 seconds so
the user will know that the fireplace is
operating.
