Will the AVR-S670H damage the B6.2?

No. The AVR-S670H is rated for the B6.2's 6 Ω load as it comes.

What impedance setting should I use for the B6.2 on the AVR-S670H?

None: the B6.2 is 6 Ω, and the AVR-S670H needs no change for it.

Is the AVR-S670H powerful enough for the B6.2?

Comfortable. From a seat 2 m away, loud 95 dB movie peaks take about 26 W per speaker, and the AVR-S670H is rated 75 W per channel. Cinema reference level, 105 dB peaks, takes about 253 W.
