When the fresh, cool make-up water is heated in the boiler the minerals fall out as sediment and the oxygen escapes as a gas. Both can result in reduced boiler life. The accumulation of sediment can eventually isolate the water from contacting the cast iron. When this happens the cast iron in that area gets extremely hot and may eventually crack.

Probe type low water cutoff devices require annual inspection and maintenance! Although these devices are solid state in their operation, the probe is exposed to possible contamination in the boiler water and subject to fouling. Refer to Low Water Cutoff Service Instructions for complete, step-by-step inspection and cleaning instructions.

See Figure 22. Figure 22: Securing Draft Hood to Canopy WARNING Do not alter boiler draft hood or place any obstruction or non-approved damper in the breeching or vent system. Flue gas spillage can occur. ETL/ETLC certification will become void.
Oxygen contamination of boiler water will cause corrosion of iron and steel boiler components, and can lead to boiler failure. Burnham's Standard Warranty does not cover problems caused by oxygen contamination of boiler water or scale (lime) build-up caused by frequent addition of water.

The low water cut off must be mounted in the system piping above the boiler. The minimum safe water level of a hot water boiler is just above the highest water containing cavity of the boiler; that is, a hot water boiler must be full of water to operate safely (see XII.

ALL trapped air must first be removed from the boiler. A loss of pressure during such a test, with no visible water leakage, is an indication that the boiler contained trapped air.
VI. Gas Piping WARNING Failure to properly pipe gas supply to boiler may result in improper operation and damage to the boiler or structure. Always assure gas piping is absolutely leak free and of the proper size and type for the connected load.

High altitude boiler models are identifiable by the third digit in the model number suffix on the rating label: Doe not use matches, candles, open flames or other ignition source to check for leaks.
Clean chimney if previously used for solid or liquid fuel-burning appliances or fireplaces. DANGER Inspect existing chimney before installing boiler. Failure to clean or replace perforated pipe or tile lining will cause severe injury or death. Boiler Equipped With Vent Damper 1.

At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system...
VIII. Electrical Positively assure all electrical connections are unpowered before attempting installation or service of electrical components or connections of the boiler or building. Lock out all electrical boxes with padlock once power is turned off. Failure to properly wire electrical connections to the boiler may result in serious physical harm.

Boiler is now ready to be put into service. CONDENSATION — Following a cold start, condensation (sweating) may occur in a gas fired boiler to such an extent that it appears that the boiler is leaking. This condensation can be expected to stop after the boiler is hot.
Assure that all gas valves and electrical disconnect switches are off before attempting any disassembly or service. Do not attempt any service work if gas is present in the air in the vicinity of the boiler. Never modify, remove or tamper with any control device.

Entrained in make-up water are dissolved minerals, salts, and oxygen. When the fresh, cool make-up water is heated in the boiler, the minerals fall out as sediment, the salts coat the inside of the boiler, and the oxygen escapes as a gas. The accumulation of sediment eventually isolates the water from contacting the cast iron.
