A. High limit control test

Set thermostat high enough for water tempera- ture to reach high limit control setting of Aquastat. When this temperature is reached, the high limit switch should open and the main gas valve should close automatically.

B.Gas control safety shutdown test

With main burners firing, disconnect the ignition cable from S8600 ignitor (see Figure 9). Gas valve should shut off the main burners.

C.Air flow pressure switch test

With main burners firing, remove plastic hose from Pressure Switch (see Figure 7). Gas valve should shut off the main burners.

WARNING: If any of the above controls fail to operate properly, they must be replaced.

D.Checking for gas leaks

Using soap solution, check for gas leaks from meter to burner, including gas piping, manifold and pilot burner.

DO NOT use open flame.

2.Venting system inspection See Page 3 for instruction.

3.Condensation drain trap inspection See page 4 for instruction.

4.Piping inspection Check the following:

A.Water piping and accessories for leaks. Slightest leaks should be corrected.

B.System to be full of water and pressure to remain stable at correct setting on gauge.

C.Air-control system. Noise and air binding in radi- ation should not occur.

D.Low water cutoff for operation (see instructions furnished with unit).

E.Check water pressure and add water slowly to system when needed. If much water is added, venting may be necessary. Regular loss of water from boiler system may indicate either a system leak, or a faulty air control system, or a faulty automatic fill valve.

5.Boiler room air supply inspection

Check air vents for continued positive supply of air as required. Air needs are greatest in cold weather. Air vents must be open and free of obstruction.

WARNING: The flow of combustion and ventilating air to the boiler should not be obstructed.
