Keep the temperature hot to produce less visible smoke. The heating is at its most efficient when the tub is covered and the fire in the heater is as hot as possible.

    Ensure that there are no flammable materials in front of or under the fire chamber. The heater will not heat up above the water temperature as the stove is surrounded by a water jacket. Make sure that there is enough water in the tub.
