GV100W BOILER

INSTALLATION & OPERATING INSTRUCTIONS

Controls/Burners

Refer to the BOILER OPERATION and CHECKING and ADJUSTMENT sections in this manual.

1.Check the thermostat for proper operation.

2.If the boiler has been equipped with a low water cut-off device, L.W.C.O, ensure that it operates properly. A float type L.W.C.O. should be flushed out.

3.The relief valve should vent water when the test lever is lifted. It should not weep or discharge water at normal system pressure. Never try to clean or repair the relief valve! If the valve fails replace it!

4.The aquastat high limit controls the maximum water temperature in the boiler. It is adjustable from 140°F, 60°C, to 220°F, 104°C. If the water temperature reaches the set temperature before the demand for heat has been met, the aquastat high limit should shut the burners off. The outlet water temperature should never exceed 220°F, 104°C. If the aquastat high limit fails to function properly replace it.

5.Visually check the burner flames. See FIG. NO. 18.

INSTRUCTIONS TO THE INSTALLER

The installer must give this copy of the INSTALLATION AND OPERATING INSTRUCTIONS to the boiler owner and make sure that the owner or operator has a basic understanding of the following:

1.The lighting instructions, the type of ignition system installed and how it operates.

2.What the labels on the boiler say.

3.How to start up and shut off the boiler.

4.How to turn the gas and electrical power on or off.

5.What to do if the boiler ignition system locks out.

6.Where to check the system temperature and pressure and what they should be.

7.The importance of reading, understanding and following these instructions.

The installer must make sure that the owner knows to shut the boiler off and call for service if the following conditions occur:

1.Yellow lazy flames or flames outside the boiler jacket.

2.Gas smell or other strange odors.

3.Discoloration of the boiler or surrounding materials due to overheating.

4.Water leaking from the heating system piping or relief valve.

5.Flue products leaking from the vent system into the living space. Dampness or condensation in the building is a good indicator of this condition.

6.The boiler’s flame roll-out safety system is actuated.

7.Control malfunction or sporadic operation.
