apparatus areas is thermostatically controlled for a minimum of 55 degrees F.
b) Provide a switch activated by opening the overhead doors to
override the space thermostat to stop the heating equipment in the apparatus
area. Provide a minimum temperature thermostat field set at 34 degrees F to
override the heating deactivation switch during door-open periods of
subfreezing ambient temperatures. After the doors are closed, the space
thermostat should resume control. Design for heating systems recovery time of
30 minutes after the doors are closed.
Ventilation. Provide roof-mounted ventilation fans for the
apparatus areas. Provide direct connections for outdoor discharge of exhaust
in areas where vehicle idling is anticipated.
