Detailed Service Procedures

Controls requiring annual service:

WATER RELIEF VALVE:

Check operation of water relief valve. Follow instructions on label fastened to relief valve.

Scald potential. Do not check operation of relief valve unless discharge piping has been installed according to Boiler Manual.

If piping is not in place, a qualified service techni- cian must properly install piping.

CIRCULATOR:

Follow oil-lubricating instructions on circulator. Over-oiling will damage circulator. Water-lubricated circulators do not need oiling.

General description of control operation:

AUTOMATIC AIR VENT:

Air is released when cap is unscrewed one turn. If air vent leaks, remove small cap on top of vent, push in stem of valve and then release to clean valve seat. Screw cap completely on, then unscrew one turn.

WATER RELIEF VALVE:

Provides discharge if boiler pressure exceeds 30 psig.

TEMPERATURE LIMIT CONTROL:

If high boiler water temperature occurs, control shuts down burner, but allows circulator to run as long as there is a call for heat. Limit should be set higher than temperature needed for the sys- tem. Maximum limit setting is 2200F.

CIRCULATOR:

Circulator provides forced water circulation through boiler and piping system.

PRESSURE-TEMPERATURE GAUGE:

Provides reading of boiler pressure and tempera- ture. Maximum boiler pressure is 50 psig, maxi- mum water temperature is 2200F. Temperature will vary according to system and daily heating de- mands. The range will be from room temperature up to limit control setting.

TANKLESS WATER HEATER:

Weil-McLain tankless heater ratings are based on 2000F boiler water temperature. To get rated out- put, set tankless heater control to 2000F. Control can be adjusted to meet system hot water re- quirements.

EXPANSION TANK:

As water heats up, it expands. Tank provides a place for increased water volume. May be open, closed, or diaphragm-type. If relief valve opens frequently, expansion tank may be water-logged. Drain tank and re-establish proper air cushion.

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

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

3.Diaphragm-type - Welded gas tight with a rubber diaphragm to separate air from water. Tank must be located near boiler before inlet to circulator.

An air vent must be installed in air vent tapping on boiler when this type of tank is used. This eliminates air in system. Normal cold water fill pressure is 12 psig. Tank pressure may be checked with an air pressure gauge.
