OPERATING INSTRUCTIONS cont.
OPERATION DURING POWER FAILURE CONDITIONS
• Your system was designed as a forced air system; do not expect regular performance without the fan
running. Do not over fi re to compensate for the lack of a fan. Your system will perform at a lower capacity
in the gravity mode.
• During a power failure never fi ll the fi rebox above the top of the fi rebox liner bricks.
• Remove the cabinet door from the blower. Remove the air fi lter and open all registers to facilitate free air
fl ow.
• Lift the left manual draft control lever until it stays up. Th is will open the draft to a pre set level, see fi g. 26
• When the power returns the damper motor will open (aft er pressing the reset button on the limit switch)
and the manual control will return to normal position. Even without the manual control open the factory
adjusted bleed air system will provide some combustion air. When power is restored reinstall the blower
system, air fi lters, and door.
Without the blower running, high temperature in the system builds up quickly and over fi ring will result in
permanent damage to the fi rebox. Maintain a small fi re only. Over fi ring voids all product warranties.
