1 OPERATION OF THE APPLIANCE

The purpose of the Intergas Compact HRE OV wall mounted gas fired boiler is to heat water and to supply it to the central heating (CH)
system and when an indirectly heated domestic hot water storage cylinder is installed, apply heat to the domestic hot water (DHW)
installation. The Intergas Compact HRE OV boiler is designed for use in open vent systems with a header tank.

The appliance is fitted with a modulating control. This means that the power is adjusted in line with the required heat. The boiler
controller responds to each call for heat from the heating or the DHW system by igniting the burner and monitoring the flame.

1.1 Operation of the central heating

The call for heat arises as a result of the room temperature being lower than the temperature set on the room thermostat. The central
heating temperature control modulates on the basis of the set central heating supply temperature. This means that when the desired CH
supply temperature is approached the appliance adjusts the power. The pump for the CH has a post purge period of 1 minute. The post
purge period may be changed if desired. The pump runs automatically for 10 seconds once every 24 hours to prevent blocking.

1.2 Operation of domestic hot water supply

By connecting the Compact HRE OV to a DHW storage tank the DHW circuit can be heated. The built-in regulation ensures that the
DHW demand takes preference over a CH demand. During delivery of hot tap water no heat is supplied by the appliance to the central
heating system.
