The circuit should be run to the junction box mounted on the front of the boiler back plate in the control compartment (See Figure 1), and connected to the proper leads therein. Wires from the low voltage thermostat should be run to terminals R and G on the transformer.
III. Operating Instructions Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on the boiler when the boiler underwent tests specifi ed in ANSI Z21.13. INSPECT INSTALLATION BEFORE STARTING. INITIAL START a. FILL ENTIRE HEATING SYSTEM WITH WATER and vent air from system.

Water manometer or water column gauge should be connected to a shutoff valve installed in the 1/8” pipe tapping in the gas valve - boiler off. By installing gas valve up stream of manometer, gas pressure can be introduced gradually - without shutoff valve, surge of pressure when boiler is turned on, could blow liquid out of manometer.
