I recently purchased a townhouse that has an Apollo Hydro heating system, Model# 30AHW3B.
Lately, my area has been having some cold nights, so I turned on the heater. However, while there was air flow, there was no heat.
I hear the furnace pilot light turn on when someone takes a shower, and there's hot water. Do I need to "winterize" the furnace by making some sort of change to it?
