PROCEDURE IN EVENT OF POWER FAILURE

Should your electricity go off during the heating season, there are several procedures that should be followed in order that you may continue to safely operate your heating system. These procedures apply to the solid-fuel boiler, as the gas or oil-fired boiler, if any, will be completely inoperative.

1.Locate any “flow-check” valves in the system (See Pg. 7), and completely unscrew the knob on the top of all these valves. (This will allow a certain amount of heated water to circulate by convection throughout the house, preventing the pipes from freezing and keeping the house partially heated).

Note: This does not apply to gravity systems, as they have no flow-check valves, and will continue to operate normally without electricity.

2.The automatic draft regulator will continue to control the wood fire in the absence of electric power. It is important to remember that the heating system cannot dispose of a great deal of fuel without a circulator running.
