Additonal cold water capacities from the thermostatic air vent under start-up conditions

Capacities shown above are based on condensate at saturation temperature. Under start-up conditions when the condensate is cold

the internal thermostatic air vent will be open and provides additional capacity to the main valve. The following table gives the minimum

additional cold water capacities from the air vent.
