TROUBLESHOOTING
WARNING
: If you smell gas:
• Shut off gas supply.
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

IMPORTANT
: Operating heater where impurities in air exist may create odors. Cleaning supplies, paint, paint remover,
cigarette smoke, cements and glues, new carpet or textiles, etc., create fumes. These fumes may mix with combustion air and
create odors.
WARNING
: Turn off and let cool before servicing. Only a qualified service person should service and repair heater.
CAUTION
: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage ODS/pilot unit.
