8 V Knockdown Boiler Assembly Instructions 6 A. Prior T o Assembly 1) Thoroughly inspect the cast iron heat exchanger for any shipping damage, i.e. cracks in the castings, broken lugs or punctures due to mishandling. 2) Do not use a damaged heat exchanger .
9 7 8) Slide or walk the assembly into its permanent position. DO NOT DROP . 9) The assembly must be level in both directions and supported around the entire base bottom. Shim and grout under base if necessary. 10) The flame roll-out switch has been mounted to the burner access panel at the factory.
10 8 C. Jacket Assembly 1) Align the left jacket side panel with the screw holes located on the upper flange of the left base end panel and loosely attach the left jacket side panel with two #10 x 1/2” sheet metal screws as shown in Figure 6. 2) Repeat Step 1 for the right side panel.
11 5) Lay the jacket top panel on top of the jacket side and rear panels. Locate the top of the rear jacket panel to the inside of the jacket top panel.

19 17 VII V enting V ent installation must be in accordance with local building codes, or the authority having jurisdiction, or Chapters 7 and 10 of the National Fuel Gas Code, NFP A 54/ANSI Z223.
20 9) Series 16 boilers are supplied with an external draft hood which must be installed as shown in Figure 15 without alteration. Before installing the draft hood, verify that the model number marked on the draft hood matches that of the boiler being installed.
21 b) Vent damper is factory shipped having approximately ¾” diameter hole in the vent damper blade, which must be left open for boilers equipped with standing pilot, and should be plugged on boilers with an intermittent pilot, using the plug supplied with the damper.
22 Removing An Existing Boiler From A Common Chimney In some cases, when an existing boiler is removed from a common chimney, the common venting system may be too large for the remaining appliances.
23 VIII System Piping A. Standard Heating System Piping 1) Figure 18 shows typical boiler system connections on a single zone system. Additional information on hydronic system design may be found in Installation of Residential Hydronic Systems (Pub. #200) published by the Hydronics Institute in Berkeley Heights, NJ.
24 this low water cutoff have a manual reset function. The low water cutoff may be a float type or probe type, but must be designed for use in a hot-water system. The low water cutoff should be piped into the boiler supply just above the boiler with no intervening valves between it and the boiler.

26 Figure 19: Recommended Piping for Combination Heating & Cooling (Refrigeration) System 24.
27 25 IX Gas Piping 1) Gas piping to the boiler must be sized to deliver an adequate supply of gas for the boiler to fire at the nameplate input with the inlet pressure at the gas valves between the minimum and maximum valves shown on the rating plate.
28 26 X Contr ol System W iring WARNING All wiring and grounding must be done in accordance with the authority having jurisdiction or, in the absence of such requirements, with the National Electrical Code (ANSI/NFPA 70). 1) Provide the boiler with a dedicated branch circuit with a fused disconnect.
29 27 Sequence of Operation – S tandard Boiler Wiring 1) All low water cut-of fs and auxiliary limit controls are wired in series so that the boiler will not operate if any of these controls are open. Under normal circumstances, only the operating control contacts will be open.

32 Safety Control Operation T emperature Limit Control – The temperature limit control interrupts burner operation when the supply water tempera- ture exceeds the set point.
33 31 XI S tart-up and Checkout Use the following procedure for initial start-up of the boiler: 1) Make sure that the boiler is filled with water. 2) Check all new gas piping for leaks and purge piping sections that are filled with air. See the National Fuel Gas Code for additional information on testing and purging gas lines.
34 32 WARNING FAILURE TO FOLLOW THE FOLLOWING PROCEDURE EXACTLY COULD RESULT IN OVER-FIRING OF THE BOILER AND A CARBON MONOXIDE HAZARD. 8) Upon initial start-up, the gas train will be filled with air. Even if the gas line has been completely purged of air, it may take several tries for ignition before a flame is established.
35 Figure 25: Gas Valve Detail - Robertshaw 7000DERHC 33 14) Test thermostat operation while the boiler is running. Turn the thermostat to the lowest setting. Both pilot burner and main burners should stop firing and the vent damper (if used) should close.
