  If you're having to fill the furnace with water more then once a week or more then a few gallons of water per week and there is no obvious explanation: * Check the temperature settings and gasket on the door and ash drawer to ensure the furnace is not over temperature and steaming. * Check the perimeter of the furnace for water puddles collecting or dripping from the furnace. * Check all plumbing in the system to ensure there are no leaks.

  If your Heatmaster furnace runs but the water isn't heating up, try these checks: * Inspect the fire. * Confirm the fan is working. * Ensure the damper and blower box elbow are open for air injection. * Verify the furnace size matches the heat demand. * Assess fuel quality; poor fuel yields fewer BTUs. * Check the furnace water level. * Look for ash and creosote blockages at the chimney and bypass trough. * Confirm temperature settings; the high-temperature setting should be at least 165°F. * Check for power at the furnace. * Make sure all system pumps are running. * Inspect for leaks, hot/wet spots, or pipe damage that could compromise insulation. * Measure water temperatures at the furnace exit, building entry, and before/after each heat exchanger.
