OPERATING CONTROLS
Model W1 with On/Off Controls
The boiler is equipped with an adjustable tankstat. Set dial for desired temperature.
Models with Mechanical Modulation: H1, H5, W2, N, R
Sizes 133 through 1826. These boilers are equipped with modulating gas valves. They have one or more valves
in addition to the main electric gas valve. Their purpose is to adjust the firing rate to meet the required load. The
modulator will throttle the boiler input to meet the system demand. The valve has a remote capillary bulb immersed
in a well at the header outlet to maintain a constant outlet water temperature. When multiple valves are furnished,
they can be staged to give greater flexibility of control. Consult the dial setting tag attached to the control for your
desired water temperature.
