Continuous Pilot Ignition / Intermittent Pilot Ignition Switch
These fireplaces have a continuous pilot ignition (CPI) / intermittent pilot ignition (IPI) switch installed under the
door. This switch allows the pilot to be switched from intermittent mode to continuous mode:
• Intermittent Mode—The pilot is extinguished when the fireplace is OFF.
• Continuous Mode—The pilot stays ON when the fireplace is OFF.
In periods of extreme cold, condensation may form on the glass door when the fireplace is OFF and the pilot is in
intermittent mode. Also, with the pilot in intermittent mode, the fireplace may cycle startup (i.e., the pilot and burner ignite,
but the burner extinguishes and reignites several times until the flue reaches the temperature for proper drafting).
• To save energy—switch to intermittent mode.
• For a standing pilot that will help prevent glass door condensation and cycle startup—switch to continuous mode.
NOTE:
Continuous mode is indicated by a pilot that comes ON and remains lit when the fireplace is OFF.
