BLOCKED VENT SHUT-OFF
SYSTEM
This heater is equipped with a blocked vent shutoff system that will automatically turn the heater off in the advent of the vent exhaust or air intake pipe becoming blocked. This blockage may be caused by snow accumulation, insects, small animals, animal nest, etc.
Once this occurs the heater will remain in a lockout cycle for one hour. After one hour there will be an ignition attempt. If the blockage has been removed, the heater will return to normal operation. If the blockage remains, the heater will return to a one hour lock out cycle.
If this problem occurs, homeowners must not attempt to operate or repair the heater themselves but contact a qualfied service agency.

MAINTENANCE INSTRUCTIONS
For correct and safe operation, keep heater and heater area clean. At regular intervals, turn control valve to OFF, let heater cool and clean inside control and heat exchanger compartments.
To clean outside cover, use a damp cloth, do not use any kind of solvent or cleaning fluid as they may leave a residue that could burn or give off odors when heater is turned on.
Have heater, including exhaust/intake tubes, checked, cleaned and/or repaired by a qualified service technician prior to use each year.
Follow a regular service and maintenance schedule for safe and efficient operation.
Do not obstruct combustion, ventilation or circulating air.
Do not place furniture in front of heater.
Keep bushes, shrubs, etc. trimmed to maintain a 12” clearance below and 48” from back of heater.
If any components are removed, make sure all gaskets are reinstalled and are in good condition. If any sign of damage, replace gasket as this is a sealed system and must be air-tight for proper operation. DO NOT operate heater with any gasket missing or damaged. Failure to replace a missing or damaged gasket may result in property damage, personal injury, loss of life, or poor performance.
