LD-60 LD-70 1000 B. The Liberty II Boiler has full wet base sections which surround fire- box for maximum heat absorption of burning fuel, and low floor temperature. C. If boiler is to be located over buried conduit containing electric wires or telephone cables, consult local codes or the National Board of Fire Underwriters for specific requirements. - Page 4 See NOTE (2) below. (1) Test for sufficient air for combustion by infiltration by running this boiler for 30 minutes under all of the following conditions and at the same time: a) all doors, win- dows and other like openings must be closed, b) all fuel burning appliances should be FIRING, c) all exhaust fans and clothes dryers turned ON. At the above conditions the CO 2 , smoke and draft readings must be normal.
