HOT WATER HEATING1

The YORK Millennium Rooftop units (30 - 40 Ton sizes) can be furnished with a YORK hot water coil as the source of heat (Bottom Supply Only). A one or two row coil will be factory installed in the heating section downstream of the supply air fan and just above the supply air opening in the bottom of the unit.

The hot water control valve will not be provided. The installer will need to field supply a water valve. The installer must also connect the hot water piping, and valve wiring at the job site for the hot water heat section to be operational.

For all hot water coils the entering water temperature should not exceed 200°F.

PIPING CONNECTIONS

The hot water piping must enter the unit through the floor of the heat section compartment. The access doors to the com- partment are gasketed so the compartment can be sealed. However, as added protection for water leakage into the space, the piping access holes should be sealed with a heat resistant mastic (see the following illustration for approximate location of the compartment and piping connections.

1.Hot water, steam or electric heat is not available for front or rear supply.
