Locate one close to the tank and the other close to the burner ahead of the fil- ter. Some filters come with built-in shutoff valves. Install a generous capacity filter inside the building between the fuel tank shutoff and burner. For additional information consult the burner section of this manual. LWLCWH COLUMBIA BOILER COMPANY REV. 13106... - Page 15 Use the following tables to determine the size of the main gas line required for the boiler that is being installed. First determine the required input volume of gas needed at the gas manifold, then deter- mine the correct pipe size for the length of run needed. LWLCWH COLUMBIA BOILER COMPANY REV. 13106...
- Page 16 Vent lines, if required, are to be run outside the building, stopping clear of windows or fresh air intakes. The vent should terminate in a way that will not allow the possibility of water, dirt, insects, animals, and other matter from entering and clogging the vent pipe.

Page 24: Control Descriptions
STEAM BOILERS Pressure Controls All Columbia steam boilers are controlled by both operating and safety limit Pressure Control. Both devices are adjustable and use pressure actuated mercury switches. These switches open when pressure reaches the main scale set point value, cycling the boiler off. - Page 25 If the valve discharges on its own, contact a qualified service technician to determine the cause. This may be an indication of equipment or system malfunction. LWLCWH COLUMBIA BOILER COMPANY REV. 13106...
- Page 26 HOT WATER BOILERS Aquastat ® Controllers All Columbia water boilers and indirect water heaters are controlled by both operating (Honeywell L4006A-100-240F) and safety limit (Honeywell L4006E 130-290F) Aquastat ® Controllers. The safety limit should always be adjusted higher than the operating limit under normal operating conditions. If for any reason the water temperature would exceed the operating limit and not trip the control, the safety limit should break the circuit to the burner.

Page 27: Maintenance
A. Gas boilers: Close fuel supply to pilot and main gas and check shut down timing. B. Oil boilers: Remove cad cell leads and check shut down timing. 2. Check fuel valves; Open limit switch and make aural and visual check. 3. Check ignition system flame signal. LWLCWH COLUMBIA BOILER COMPANY REV. 13106... -
Page 28: Monthly Boiler Check & Maintenance List
DO NOT OPERATE THE BOILER WITHOUT THE GAUGE GLASS PROTECTOR INSTALLED. NEVER ATTEMPT TO WORK ON THE GAUGE GLASS WHILE THE BOILER IS UNDER PRESSURE. ALWAYS CLOSE GAUGE VALVES PRIOR TO TIGHTENING GASKETS ON WATER LEVEL GAUGE GLASS. SERIOUS INJURY COULD RESULT. LWLCWH COLUMBIA BOILER COMPANY REV. 13106... - Page 29 Then go back to the boiler blowdown valve, open and close the valve, very fast, two more times. Repeat this procedure with the low water cut off valve. This will rid the boiler of most precip- itated sediment. DO NOT EMPTY THE BOILER OF ALL ITS WATER. LWLCWH COLUMBIA BOILER COMPANY REV. 13106...

Page 30: Water Treatment
The pH should be maintained between a minimum of 10.5, and a maximum of 11.0 to prevent acidic corrosion of boiler tubes and plates, and to provide for the precipitation of scale form- ing salts before scale is deposited. LWLCWH COLUMBIA BOILER COMPANY REV. 13106... - Page 31 High boiler solids will lead to foaming, priming, surging and carry over. These problems can be over- come by proper, daily blowdown of the boiler. LWLCWH COLUMBIA BOILER COMPANY REV. 13106...

Page 33: Appendices
Twin Units and Tank Systems If larger volumes of hot water are required beyond the range of the largest Columbia water heater, we would suggest either using multiple units or combination tank systems. The combination tank system consists of a galvanized storage tank of suitable capacity connected to the water heating coils in the Columbia indirect water heater through a bronze or stainless trimmed circulating pump. - Page 34 LWLCWH COLUMBIA BOILER COMPANY REV. 3107...
