CORROSION CONTROL
To control corrosion of the Outdoor Water Furnace, we recommend the following:
1.
Use proper certified boiler treatment as recommended by the furnace manufacturer.
2.
Use antifreeze as described under Water Fill-Up.
3.
Always maintain adequate water level. If level drops occasionally, check for leaks or boiling of
boiling water and refer to the Troubleshooting Section.
4.
Make sure the Outdoor Water Furnace is properly grounded.
5.
Remove ashes when Outdoor Water Furnace is not used.
6.
Cover the chimney during off-season to prevent rainwater from entering the firepot.
7.
Clean the firepot during the off-season.
8.
Clean the heat exchanger with the cleaning tool provided with the Outdoor Water Furnace,
through the cleaning door located above the wood-loading door.
CREOSOTE CONTROL
The Optimizer when operated properly will have little or no creosote in the heat exchanger
tubes, all that should accumulate there is very light ash or dust. If creosote does form in the
heat exchanger tubes then the gasification process is not working properly.
Accumulations of creosote when ignited may result in chimney fires.
We recommend inspecting the chimney once a month during the heating season and removal
of creosote linings to reduce chimney fire hazards.
Green or unseasoned wet wood or wood that is not covered with a roof will likely be higher
that 25% moisture. This wood will cause creosote to form.
Leaky door gaskets will also cause creosote to build up.
ASH DISPOSAL
Ashes should be removed from the Outdoor Water Furnace regularly or they will block the flow
of air exiting the fire box.
Ashes should be stored in metal containers with tight lids and kept in an area free of
combustible materials until finally disposed.
Do not dispose of ashes while embers are still hot.
Check local by-laws for ash disposal. Wood ash can be used to reduce soil acidity or as a
fertilizer for the garden.
SAFETY WARNINGS
Never leave children un-attended near the outdoor water furnace/boiler.
Never add water when outdoor water furnace temperature is close to 212 f as it
may result in steam flashing.
Never perform any service or maintenance work before water temperature drops
below 100 F.
DO NOT store combustible materials or liquids near the Outdoor Water Furnace.
DO NOT burn any materials other than natural wood.
DO NOT use flammable liquids or materials to start or to enhance the fire.
DO NOT leave wood loading door open or unlatched.
