STORAGE

CAUTION: Disconnect heater from natural gas supply.

1.Place plastic cover cap over brass fitting on inlet connector.

2.Store in dry, clean, and safe place. Do not store hose inside heater combustion chamber.

3.When taking heater out of storage, always check inside of heater. Insects and small animals may place foreign objects in heater. Keep inside of heater free from combustible and for- eign objects.

MAINTENANCE

WARNING: Never service heater while it is plugged in, connected to gas supply, operating, or hot. Severe burns and electrical shock can occur.

1.Keep heater clean. Clean heater annually or as needed to re- move dust and debris. If heater is dirty or dusty, clean heater with a damp cloth.

2.Inspect heater before each use. Check connections for leaks. Apply mixture of liquid soap and water to connections. Bubbles forming show a leak. Correct all leaks at once.

3.Have heater inspected yearly by a qualified service agency.

4.Keep inside of heater free from combustible and foreign objects.
