❏Start-up . . . . . . . . .

4. Check gas piping, per manual Sections 5 and 7,

1.Start the boiler, following the instructions in manual section 7.

2.Verify cold fill pressure is correct and that fill system is working properly.

3.Verify antifreeze level (if used) is at the right concentration and that inhibitor level is correct.

verifying no indications of leakage and all piping and connections are in good condition.

5.Read the Lighting instructions (Figure 21 of this manual or on boiler label) applying to the boiler.

6.Start the boiler following the Lighting instructions and manual section 7.

❏Check/test . . . . . . .

Gas piping

1.Sniff near floor and around boiler area for any indication of a gas leak.

2.Test gas piping using bubble test, per section 5 of this manual, if there is any indication of a leak.

Cold fill and operating pressures

1.While the system is cold, note the pressure reading on the boiler pressure/temperature gauge.Verify that cold fill pressure is correct.

2.Watch the pressure as the boiler and system heat up to ensure pressure rise is normal. Too high a rise would indicate a waterlogged or undersized expansion tank.

2.Inspect and test additional limit controls or low water cutoffs installed on system.

Air vents and air elimination

1.Inspect automatic air vents (if used). Also inspect air separators to ensure they are operational.

2.The cap must be unscrewed one turn to allow air to escape.

3.See Figure 22. If the air vent is leaking, remove cap A and briefly push valve B and then release to clean the valve seat.

4.Replace cap A by twisting all the way onto valve B and then unscrewing one turn.

Limit controls and cutoffs

1.Inspect and test the boiler limit control. Verify operation by turning control set point below boiler temperature. Boiler should cycle off. Return dial to original setting.

Expansion tank

1.Expansion tanks provide space for water to move in an out as the heating system water expands due to temperature increase or contracts as the water cools. Tanks may be open, closed or diaphragm or bladder type. See section 3 of this manual for suggested best location of expansion tanks and air eliminators.

Open-type— located above highest radiator or baseboard unit, usually in the attic or closet. Has a gauge glass and overflow pipe to a drain.

Closed-type— welded gas tight and located above boiler. Tank is partially filled with water, leaving an air cushion for expansion.

•Make sure this type of tank is fitted with a tank fitting, such as the B & G Tank-Trolor Taco Tac o-Trol. This fitting reduces gravity
