OK to combine neutrals in a fixture?

Hi,
I'm installing a vent/heater/night light/light combination. In its junction box, it has four hots and four neutral wires. Is it OK to splice the neutrals together at the fixture's own junction box? (If yes, then how come they give you four?)
Thanks!

Depends on what you're splicing them to...it would be possible to power various parts from differing circuits in which case they shouldn't be joined except to the proper neutral.

Exactly. if the light is on a different circuit from the fan/heater, for example, you'd want the light functions connected to the neutral of the lighting circuit and the fan/heater conneted likewise.

They give you four so that you can separate them if the power to the loads is not all from the same circuit. The grounded current carrying conductors of different circuits must not be connected to each other at any point except in the enclosure of the Circuit Overcurrent Protective Device.
