UMP
On initial start up if the pump is not primed with water it may squeal and can burn your pump out.
Make sure the ball valve to the pump is open and the water tank is full.
On occasion the pump may get a piece of debris in the impellers from the installation process. Shut
the ball valves off and remove the pump. Take a clean garden hose and spray water through the
impeller housing to wash out any debris. Then replace the pump and start it back up.

It is not recommended that you operate the furnace for very long with the door open. This will cause
your furnace to over heat.

ATER IS NOT GETTING HOT
Several things may contribute to this problem.
Check that the fire is getting enough air. Make sure there is not obstruction in the chimney or
in front of the blower hole.
Ashes may be built up too much in the fire chamber. Before you stoke the fire make sure you
take a shovel or some device and rake the coals towards the middle of the furnace. Ash build up
around the edges work to insulate the fire box from the fire and do not let it heat like it was designed
to.
You may be burning too much green wood. It takes a large amount of Btu’s to burn/boil off
the water in a green log. This makes the fire burn cooler than when you use seasoned wood.
Your water lines may not be insulated enough. If you have exposed lines, or lines that run through
uncontrolled environments you may look into insulating them or putting more insulation on them.
Insulation is key to your performance.
Your blower in the house will drop the water temperature as much as 20 degrees. If the
temperature of the furnace water is not above 150, it makes it real hard to recover temperature loss
when the blower is on. Try turning the blower off and work with the fire to recover heat in the water.
