Appendix Appendix A-Automix Plumbing Notes



Appendix B-Overheat Loop: No Electricity

The piping and controls must be connected to the boiler in such a way that in the event of a power fail-ure there is one loop of radiation available for gravity circulation. This loop must not be obstructed by any valves or other accessories which would prevent gravity circulation during a power failure. The piping is plumbed in such a way that excessive pressure will not be developed in any portion of the boiler or system. The loop must be large enough to dissipate at least 10% of the boiler’s maximum rated heat output, assuming an ambient temperature of 65 °F (18 ºC) and a mean water temperature of 180 ºF (82 ºC). The minimum pipe size for this loop is ¾” and if possible, the loop should be located and pitched to maximize natural thermal convection of the water. The loop must be positioned above the boiler. The design of the loop must be such that it can be made inoperative only in a deliberate manual action. If large enough, an existing heating radiation zone may be used for the over-heat loop. The loop must be equipped with zone valves which will open automatically during a power failure. We recommend AUTOMAG zone valves for this application (offered as an accessory).

Overheat Example



Appendix C-Thermostatic Mixing Valve A Thermostatic Mixing Valve or Loading Unit must be incorporated into the heating system piping as shown in the figure below. When the Mixing Valve is used a ball valve (I) (not provided) must be in-stalled upstream of Port 1 of valve TV-1. The valve should be set at half open (and the handle re-moved after it is set), in order for the tempering loop to function correctly. If there are unions included with the Mixing Valve or the Loading Unit, the internal valves must be fully open. A circulator is inte-grated into the Loading Unit, so a circulator is not required.



Appendix D-Overheat and Circulator Aquastat Wiring Connections For boilers without connections for the overheat aquastat or boiler circulator, please use the connec-tions below:

TERMOVAR LOADING UNIT is a pre-fabricated, automatic, thermally operated valve unit for solid-fuel boiler/storage tank installations, where heating and domestic hot water are taken from the storage tank. TERMOVAR LOADING UNIT ensures a minimum return-water tempera-ture into the solid-fuel boiler, which increases the boiler efficiency, prevents tarring and considera-bly prolongs the lifetime of the solid-fuel boiler. TERMOVAR eliminates the risk of destructive thermal shock caused by surges of cold water re-turn water. TERMOVAR renders a more effective burning and is therefore a necessary part of a solid fuel installation with a storage tank.

Termovar Loading Unit

Termovar Includes: 1. Thermally operated loading valve 2. Backflow preventer 3. Circulator pump 4. Three thermometers 5. Three ball valves 6. Insulation EPP

Termovar Loading Unit has several advantages: • The pre-fabricated unit saves time and provides a quick and trouble-free installation. • The loading unit provides a constant loading temperature to the storage tank. • It can be installed on the right-hand or left-hand side of the boiler. • The loading unit is installed on the return pipe which means that the supply pipe is free for

expansion and the unit is never affected by steam in case of an overheated boiler. • Service friendly. All parts can be changed without draining the system.

AUTOMIX 10 is an advanced, compact outdoor reset control for hydronic baseboard, radiator, and radiant floor heating applications. AUTOMIX 10 works continuously and propor-tionally. Through impulses from the sensors the control adjusts the supply water temperature as the outdoor temperature changes. AUTOMIX 10 includes a min. and max. limiter for the supply water temperature and a freeze pro-tection feature. AUTOMIX 10 is delivered factory wired which minimizes installation problems in the field. The main supply and all sensors have plug-in connections. The quick and easy do-it-yourself installation saves on labor charges.

Termovar Loading Valve The TERMOVAR TEMPERING VALVE is an auto-matic thermally operated tempering valve for solid-fuel boiler installations with or without a storage tank. The TERMOVAR ensures a minimum return water tem-perature to the heating boiler, which increases combus-tion efficiency, prevents tarring and considerably pro-longs the lifetime for the solid-fuel boiler. The TERMO-VAR eliminates the risk of destructive thermal shock to both steel and cast iron boilers. The TERMOVAR ther-mally operated tempering valves render a more effective burning and are therefore a necessary part of a solid-fuel boiler installation.

Termovar AF Bypass Valve Termovar AF thermostatic 3-way bypass valves are de-signed to change the direction of flow in hydronic heat-ing applications. The Termovar Bypass (diverting) valve is an automatic thermally operated diverting valve for solid-fuel boiler installations with storage tank. Having a Termovar AF valve installed in your system will improve overall efficiency and improve the effec-tiveness of the heat storage tank system.
