The QVM 9 provides 2 different heating functions that operate independently from the same boiler.
One mode provides space heating water to heat the home. The other mode provides a continuous
circuit of hot water for domestic use eg, bath, laundry, etc. Both circuits are separate and operate at
different temperature ranges.
The space-heating water is controlled by the FR-5 thermostat. A special thermostat has been
provided that enables the user to either set the room temperature required or set the heating water
temperature. In some cases this thermostat may not be suitable for multi-system applications. (The
installing contractor will make this determination and install suitable alternative controls.
The domestic hot-water is controlled by the user. Because the QVM 9 is a multi-purpose design, it
can provide hot water on demand. There is no storage tank to hold hot water, when there is no use for
it. The QVM 9 will only produce hot water when you use it : instantaneously. The modulating gas
burner allows water to heat up evenly as it is being used. The QVM 9 will continue to heat the water
until the source or sources are shut off. This on-demand-use also helps to prevent water being held
in the boiler for long periods of time.

A thermostatic mixing valve should be installed on the domestic water supply pipe to control the
supply water temperature and prevent any possibility of scalding.
The QVM 9 prioritizes domestic hot water over space-heating water and will immediately stop
producing space-heating water the moment a hot water faucet or valve is opened anywhere in the
home. Once the faucet or valve has been turned off, the boiler will return to the home-heating
function again.
The QVM 9 is designed with a special sealed-combustion venting process. Both sides of the
combustion process(inlet oxygen and outlet carbon monoxide) are isolated from each other and are
totally sealed-off from the air supply within the home. Infiltration, is reduced by as much as 90%
making the QVM 9 one of the safest, most comfortable and clean-burning boilers in the world.
