(b)
Check that when the low water level control on steam and hot water boilers is
operated to indicate a low water level, the automatic fuel-feed is interrupted.
(c)
Check that when the excessive pressure control on steam and hot water boilers is
operated as in an excessive pressure situation, the automatic fuel-feed is
interrupted.
(d)
Check that when the excessive water temperature control on hot water boilers is
operated to indicate excessive water temperature, the automatic fuel-feed is
interrupted and, if appropriate, that one or more zone control valves open.
(e)
Check that if the temperature exceeds 95°C (200°F) in a furnace supply plenum
on hot air furnaces, the automatic fuel-feed is interrupted.
(f)
Check that if there is a failure of the fan providing combustion air, the automatic
fuel-feed is interrupted.
(g)
Check that if there is a failure of the combustion air supply control mechanism to
remain fully open, the automatic fuel-feed is interrupted.
(h)
Check that when the hot water circulating pump manual disconnect switch, is
opened, the automatic fuel-feed is interrupted.
(i)
Check that if there is a shutdown or failure of the mechanical flue-gas exhauster,
the automatic fuel-feed is interrupted.
(j)
Check that if there is a failure in the flue gas flow, the automatic fuel-feed is
interrupted, or the combustion air supply is shut off in manually fuel appliances.
(k)
Check for the proper operation of the minimum fire maintenance controls and
