NOTICE
In accordance with Section 325 (f) (3) of the Energy Policy and Conservation Act, Westinghouse has provided this appliance
with multiple features designed to save energy by reducing the appliance water temperature as heating load decreases.
These features include:

A modulating combustion system that adjusts firing rate based on heat demand.

Adjustment of appliance set point based on inferred heat load as determined by an outdoor sensor. The outdoor
sensor is supplied by Westinghouse with this appliance.

This appliance does not include a standing pilot.

This appliance is designed and shipped to assure the highest efficiency operation possible. Such high efficiency is
achieved by limiting heating circuit water temperature to 140°F when there is no anticipated heat load, based upon
the outdoor sensor and the Outdoor Reset Curve (sensor response curve) in the appliance software.

This feature may be over-ridden as described below in specific installations:

The appliance control is equipped with an outdoor sensor override for use with building management systems or in
cascaded systems (for systems with total input of 300,000 BTU/hr or greater).
See statement below for an important notice on the use of the override.
In accordance with Section 325 (f) (3) of the Energy Policy and Conservation Act, this appliance is equipped with a feature
that saves energy by reducing the appliance water temperature as the heating load decreases. This feature is equipped with
an override which is provided primarily to permit the use of an external energy management system that serves the same
function. THIS OVERRIDE MUST NOT BE USED UNLESS AT LEAST ONE OF THE FOLLOWING CONDITIONS IS TRUE:

An external energy management system is installed that reduces the appliance water temperature as the heating load
decreases.

This appliance is not used for space heating.

This appliance is part of a modular or multiple appliance system having a total input of 300,000 BTU/hr or greater.

This appliance is equipped with a tankless coil.
NOTICE
The CSD-1 ASME Code, Section CW-400 requires that hot water heating and supply boilers have a) a UL 353 temperature control
device, b) at least one (1) temperature-actuated control to shut off the fuel supply when system water reaches a preset operating
temperature, c) a high temperature limit control that prevents the water temperature from exceeding the maximum allowable
temperature by causing a safety shutdown and lockout, and d) its own sensing element and operating switch.
Certain AHJs, locales, and states will require that commercial boiler installations meet the CSD-1 ASME Code, Section CW-400. To
meet this code, Westinghouse has integrated a temperature control system into the 926 control provided with this heating boiler. This
control system complies with the requirements of CSD-1 Section CW-400 as a temperature operation control. The control monitors the
temperature difference between the inlet and the outlet sensor, which is affected by boiler water flow. If this temperature difference
exceeds 55°F (typically because of low water flow or very low heat load), the control will reduce the maximum fan speed. If the
temperature difference exceeds 60°F, the control will effectively sense there is little or no water flow or heat load and shut the boiler
down. The controller will restart automatically once the temperature difference has dropped below 55°F and the minimum off time (anti-
cycle time) has expired. In addition, if the control senses that the outlet water temperature has reached 199°F, the boiler is put into a
hard lockout and requires manual reset to restart.
Installers should review the regulations of the AHJ, local and state code authorities, and utility companies which pertain to this type of
boiler BEFORE performing installation.
