Bladder Gate Valve and Bladder Hose
Principle of the Bladder Gate Valve and Bladder Hose
The bladder gate valve provides water ow control in maintaining the bladder and lling the furnace with water.
The bladder hose provides a means for the water to freely ow from the water jacket to the bladder allowing
expansion and contraction.
WHEN THE HEATMOR™ FURNACE IS OPERATING,
THE BLADDER GATE VALVE MUST BE OPEN.
Maintenance / Result
To maintain the bladder gate valve, open and close the valve periodically to prevent it from seizing. Ensure that
the hose clamp is tightly fastened, securing the bladder hose to the bladder and to the bladder gate valve.
Removal and Replacement
1) Turn off the power to the furnace.
2) Drain some of the water from the furnace to prevent water from draining while you are
replacing the valve.
3) Loosen the hose clamp holding the bladder hose to the bladder gate valve.
4) Remove the bladder hose from the bladder gate valve and let the water drain from the bladder.
