General Safety Information (Continued)

•Use only original replacement parts. This heater must use design-specific parts. Do not substitute or use generic parts. Improper replacement parts could cause serious or fatal injuries.

NOTE: Because of the metal lubricant used in this product, you may notice some smoking upon initial start-up and shut down. This condition is normal and should not occur beyond the first several (5-10) minutes of operation.

•Keep all connections and fittings clean. Make sure propane tank valve outlet is clean. Check the rubber O ring on the heater inlet fuel connec- tor for damage before each use. Replace if worn or damaged.

The hose/regulator assembly attaches to the propane gas supply. This provides fuel to the heater.

THE IGNITION SYSTEM

The piezo ignitor lights the main burner.
