Installation and service certificate
This boiler is equipped with a control system that automatically adjusts a time delay period to turn on the boiler
during a call for heat. This is accomplished by circulating available hot water in the system while measur-
ing water boiler water temperature changes. The control calculates a suitable delay based on temperature
measurements and turns the boiler on only after it determines that the demand for heat cannot be satis-
fied with the available hot water.
Due to the wide variety of controls used in boiler installations, this control is also equipped with an adjustment
for the calculated time delay period (ECONOMY ADJUST). In the MIN position, the time delay is zero
and the IMPORTANT notice below must be observed:
IMPORTANT
In accordance with Section 325 (f) (3) of the Energy Policy and Conservation Act, this boiler is equipped with
a feature that saves energy by reducing the boiler 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 boiler water temperature as the heating load
decreases.
•
This boiler is part of a modular or multiple boiler system having a total input of 300,000 BTU/hr or greater.
•
This boiler is equipped with a tankless coil.
