Hi,
To get the humidity to rise more or faster, turn the "fan" switch on the t-stat to "on" and run the fan more...
The humidifier only adds moisture to the air when the air is moving through it and the air will only move through it when the blower is moving the air...
Depending on the heat loss of the house and the capacity of the heater, the fan may have to be run extra to get enough moisture to the house...the run time of the furnace it's self may not be enough...

Play around with it and see what it needs...only you know exactly what humidity you are looking for...you have the equipment to get it there you just need to figure out what the combinations are to get it there...

Make sure damper dial on humidifier if open, winter. Also most humidifiers recommend to supply unit with hot water instead of cold (evaporates faster).

Try to tighten the compression nut on the saddle valve and see if it will stop, if it does not stop then you will need to replace the saddle valve.
