Filter Assemblies, optional for 4988 Burn- ers, use inexpensive throwaway panel filters to clean air entering Zephyr blowers. On 4988-1000, -2500, -4000, and -6000-L Burners, filter housing completely encloses blower and motor; pressure taps and a conduit knockout on the housing permit connections to blower and motor. Filters for -6000-H and -9000-L Burners attach to blower inlet. Filters are shipped loose for field installation.
