The P68 also offers decorative touches as extra features, as well as a cast iron hearth pad to protect the floor.
There is a hidden control panel on the side of the stove. This is where the user can set the heat, and Harman claims the stove will maintain the set heat to within 1 degree. This is done using and Exhaust Sensing Probe system. The ESP system constantly monitors heat and adjusts.
A chimney is not required for this stove, as it is direct vent. Harman claims the glass viewing area is cleaner thanks to an air wash system, and the ash pan does not need to be emptied as frequently due to its size.

Troubleshooting and Maintenance
Most of the issues covered in the troubleshooting portion of the manual covers issues with the fire, the hopper, or the fuel. The manual notes if there is a large flame when the stove fires up, it will settle down once the fire is established.
If the stove is not feeding, the manual says it could be due to five things:
- There is no fuel in the hopper.
- The sensor for the feeding switch is not operating. This manual advises checking for closed doors, loose or missing gaskets, and the hopper lid.
- The feed motor is not running. It’s possible not enough fuel or gel was loaded.
- There is an obstruction in the hopper. The manual advises emptying the hopper and clearing the obstruction.
- The feed motor has failed.
If fuel is only being partially burned, this could be a result of one or a combination of the following:
- The feed rate is too high.
- The air to fuel mixture is off. The manual suggests checking the burn pot and cleaning out the cover and air intake.
- The burn pot or the heat exchangers may need to be changed.
