SUBROUTINE InitFurnace(FurnaceNum, AirLoopNum, OnOffAirFlowRatio, OpMode, ZoneLoad, MoistureLoad, FirstHVACIteration)

          ! SUBROUTINE INFORMATION:
          !       AUTHOR         Richard J. Liesen
          !       DATE WRITTEN   Feb 2001
          !       MODIFIED       Oct 2001, Richard Raustad
          !                      Sep 2008, R. Raustad - revised logic to determine load to be met
          !                      Bereket Nigusse, June 2010 - added a procedure to calculate supply air flow fraction
          !                      through controlled zone
          !                      Bo Shen, March 2012 - for VS WSHP
          !                      Bo Shen, ORNL, July 2012 - added variable-speed air source heat pump cooling and heating coils, using curve-fits

          !       RE-ENGINEERED  na

          ! PURPOSE OF THIS SUBROUTINE:
          ! This subroutine is for initializations of the Furnace Components.

          ! METHODOLOGY EMPLOYED:
          ! Uses the status flags to trigger initializations.
          ! The HeatCool furnace/unitarysystem and air-to-air heat pump may have alternate air flow rates
          ! in cooling, heating, and when no cooling or heating is needed. Set up the coil (comp) ON and OFF
          ! air flow rates during InitFurnace. Use these flow rates during the Calc routines to set the
          ! average mass flow rates based on PLR.
