Important Notice - HS Tarm 2000 Installation And Operation Manual

Before starting your boiler installation, we urge you to read and consider this
addendum.
Tarm Biomass strongly recommends the installation of a Termovar automatic, thermally
operated, 3-way mixing valve or loading unit with all wood or multi-fuel boilers.
When cold water returns to the boiler it causes sweating and a cold environment for
the fire which causes creosote and poor combustion.
The Termovar insures a minimum return water temperature of 160° F in the boiler.
This increases efficiency, helps prevent creosote, and considerably extends the life of the
boiler.
The Termovar helps create more efficient burning and is a recommended part of any boiler
installation.
Please call Tarm Biomass with any questions.
