The Solo Plus wood gasification boiler is a log wood fired boiler designed and constructed for highly efficient combustion of log wood. Do not burn other fuels in the Tarm Biomass Solo Plus boiler. The Solo Plus is not a self contained weather-tight boiler. It should be installed within the heated building.
4-10 days between firings to heat all your domestic hot water. Tarm Biomass offers both open atmospheric and pressure type thermal storage tank systems. Please contact Tarm Biomass or your local Tarm Biomass dealer to help recommend a thermal storage sys- tem for your Solo Plus gasification boiler.
If a fan is used in the fuel storage area, they should be installed so as not to create negative pressures in the room where the solid-fuel burning appliance is located. Solo Plus Instructions 1-800-782-9927 Version 12-13 Tarm Biomass · 4 Britton Lane · Lyme, NH 03768...
Revision of existing heating system piping may be appropriate to properly utilize the equip- ment. Although Tarm Biomass can provide advice and design detail on the integration of this boiler with the heating system of the building, the ultimate responsibility for the performance of the system rests with the installer.
The installation of these devices is absolutely necessary for safe operation of the boiler and for protection of the heating system. Solo Plus Instructions 1-800-782-9927 Version 12-13 Tarm Biomass · 4 Britton Lane · Lyme, NH 03768...
It is critical to size the boiler properly. A proper, up to date heat load calculation is advised. An accu- rate history of building fuel usage over several years can help to calculate the proper size boiler. Boiler sizing is the responsibility of the installer. Tarm Biomass bears no responsibility for boiler sizing, but can provide sizing input.

CAUTION ☼ Any plastic or rubber tubing used with a Tarm Biomass boiler must have an oxygen barrier, or boiler corrosion will occur. If radiant tubing without an oxygen barrier is installed, water in the tubing part of the heating system must be separated from the boiler. Separation of system com- ponents is typically done by using a heat exchanger.

NOTE Tarm Biomass recommends that the turbulators not be installed when a boiler is first installed. Operate the boiler without the turbulators installed until you maintain a consistent flue tem- perature of 500 ºF (260 ºC). Constant flue temperatures of less than 300 ºF (148 ºC) are too low when the turbulators are installed.
Port 2 of the Termovar and back to the boiler. Tarm Biomass recommends the use of the BLTCONTROL (available through Tarm Biomass) where the Solo Plus boiler is used with another backup boiler. BLTCONTROL is a three position control that allows switching between wood only, wood with automatic back-up, or back-up only, by control- ling the operation of the back-up auxiliary boiler.

Boiler Installation & Start-up > Control Logic Tarm Biomass recommends the use of an additional Termovar valve model 6440AF (TV2) for most installations. Without TV2 it is possible that when a small zone is the only zone calling, a master bathroom zone for instance, all of the heat the boiler is producing is drawn to the small zone.

Therefore, we do not recommend burn- ing wood in the summertime. Save your wood fuel for colder weather, or equip your boiler with a thermal storage tank system. Contact Tarm Biomass or your local dealer for more in- formation.
4.7 Operation with Thermal Storage System Tarm Biomass recommends the use of a Thermal Storage Tank System with the Solo Plus boiler. The boiler will always be able to discharge its heat resulting in better combustion, less depositing of soot and tar, and longer boiler life.
These problems are eliminated entirely when operating the boiler with higher demand on it, such as a thermal storage tank system, and have a chimney which main- tains proper draft. Solo Plus Instructions 1-800-782-9927 Version 12-13 Tarm Biomass · 4 Britton Lane · Lyme, NH 03768...
If the wood is greener, use less secondary air. To have the knob in the center, usually covers most situations. Fig 4.4 Secondary Air Adjustment Solo Plus Instructions 1-800-782-9927 Version 12-13 Tarm Biomass · 4 Britton Lane · Lyme, NH 03768...
The key to operating the boiler in the warmer months and even in the summer is to install a Thermal Storage Tank System. Contact Tarm Biomass or your local dealer for more informa- tion on Thermal Storage Tank Systems.
