The
HORNE Steam Injection Heater should be fitted as low as possible in
the tank. The HORNE EA-1 Thermostatic valve must be fitted about the
Steam Injection Heater with a gap of at least 50mm between it and the
heater.
A vacuum breaker should be fitted between the strainer and the HORNE EA1 Thermostatic Valve to prevent a vacuum forming in the steam supply pipe. Where the steam supply is below the level of the water in the tank, a non-return valve must be fitted between the HORNE Steam Injection Heater and the HORNE EA-1 Thermostatic valve to prevent water from the tank flowing back up the steam pipe, due to gravity, when the steam supply is turned off.
A stop valve should be fitted between the Steam Injection Heater and the non-return valve to enable maintenance work to be carried out on both the EA-1 Thermostatic Valve and the non-return valve.
The
HORNE EA-1 Thermostatic Valve can be mounted vertically as shown opposite.
If the level of liquid in the tank varies, the pocket on the HORNE EA-1
Thermostatic Valve must be long enough to ensure that when the liquid
is at it's lowest level, at least 230mm of the thermostatic pocket is
immersed in the liquid.
More than one Steam Injection Heater may be required and, if so, they can be fitted to a common steam supply pipe.
