Page 3: Important Notice
ADDENDUM 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. -
Page 5: Introduction
The Tarm EXCEL boilers have been tested and listed by the Omni Test Laboratories Inc. The test standards used are UL 391-1995, CAN/CSA B366.1-M91, UL726, ANSI Z 21.13- 2000, and CSA4.9-M2000 to satisfy code requirements in the United States and Canada. This manual contains installation, operation, and maintenance guidelines for all models in the HS-Tarm EXCEL series of boilers. -

NSTALLATION PAGE 10 BEFORE YOU BEGIN SAFETY NOTICE: READ THIS ENTIRE MANUAL BEFORE YOU INSTALL AND OPERATE YOUR NEW BOILER. FAILURE TO FOLLOW THE INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE OR BODILY INJURY. Contact local building or fire officials as the installation must be done in accordance with local ordinances, which may differ in some ways from this manual. -
Page 15: Chimney Requirements
NSTALLATION (continued) PAGE 11 ______________________________________________________________________________________________________________________________________________________________________________________ CHIMNEY REQUIREMENTS The chimney is one of the most critical factors in the successful operation of any solid fuel heater, including your HS-Tarm boiler. A good chimney will provide a continuous and dependable draft to pull the vented gases out of your house. NOTE: The boiler must be connected to a lined masonry or a Factory-Built Type HT approved chimney in good condition. - Page 16 NSTALLATION (continued) PAGE 12 ______________________________________________________________________________________________________________________________________________________________________________________ CHIMNEY REQUIREMENTS (continued) • Your Tarm EXCEL boiler is designed to burn efficiently and nearly smoke-free, but under certain conditions creosote deposits may form in your chimney. Chimneys that are too large, are located outside, are poorly insulated, or have bends in the flue passages are especially prone to problems with draft and/or creosote.
- Page 17 NSTALLATION (continued) PAGE 13 ______________________________________________________________________________________________________________________________________________________________________________________ BOILER PLACEMENT REQUIREMENTS • The boiler must be placed on a non-combustible floor, such as, a level concrete slab. Many owners choose to raise the boiler 8” above the floor to make loading and cleaning more convenient.

Adams have been tested and listed with the EXCEL boilers. Each Adams Burner is shipped with two orifices. The smaller orifice for the EXCEL 2000 should be in place when the burner is received. If you have an EXCEL 2200 you will need to change out the smaller orifice for the larger one as per the instructions on page 13 of the gas burner instruction manual. - Page 35 How do you add heat storage to your system? The first requirement is to get a tank. We recommend a 600-gallon tank with the Solo Plus 30, MB 40 and EXCEL 2000. Tanks of 800 gallons or more are recommended for the Solo Plus 40, Solo Plus 60, MB55, and MB 75 and the EXCEL 2200.

Page 43: A Word About Wood Fuel
PERATING OILER PAGE 38 A WORD ABOUT WOOD FUEL Wood is an environmentally desirable fuel as it is CO2 neutral. Your Tarm EXCEL boiler is designed to burn natural cord wood with high efficiency and low emissions. With properly dried and prepared wood you will fully realize the best operating, heating and clean-burning potential of your boiler. - Page 44 PERATING OILER (continued) PAGE 39 WOOD–BURNING OPERATIONS WITH HS-TARM EXCEL BOILERS CHECK LIST: 1. PRIOR TO STARTING A WOOD FIRE, CHECK THE FOLLOWING THINGS: a. Check the By-Pass Damper: Is the damper plate in place on the actuator arm? To check this you will need to remove the boiler's top jacket covers and remove the cleanout cover over the heat exchanger tubes.

Page 46: Primary Air Adjustment
PERATING OILER (continued) PAGE 41 Lighting the Boiler for the First Time (continued) Remember that once you turn the power on to activate the fan, the low temperature flue gas sensor must sense flue gas temperatures of 120°C (250°F) within 15 minutes or it will cut power to the fan. - Page 47 PERATING OILER (continued) PAGE 42 SECONDARY AIR ADJUSTIMENT When you have found the ideal setting, it should not be necessary to alter the secondary air adjustment, unless you change your fuel. If the secondary air setting is at its lowest, and the flame still spills forward out of the combustion tunnel, the primary air flow may need to be reduced (see page 41).

Page 48: Regular Stoking Of The Boiler
PERATING OILER (continued) PAGE 43 ______________________________________________________________________________________________________________________________________________________________________________________ REGULAR STOKING OF THE BOILER HINT: It is advantageous to have the wood that you are going to load ready and next to the boiler before opening the by-pass damper. This will mean less smoke spillage into the boiler room and less smoke up the chimney. -

PERATING OILER (continued) PAGE 44 ______________________________________________________________________________________________________________________________________________________________________________________ REGULAR STOKING OF THE BOILER (continued) If The Draft Fan is : (BOILER TEMPERATURE BELOW 140°F) NOTE: When the boiler temperature is below 140°F the assumption is that the fire has burned out and that hot gases are not present. However, never quickly open the door unless you have tried to vent hot gases from the firebox first. -
Page 50: Operational Procedures
PERATING OILER (continued) PAGE 45 OPERATIONAL PROCEDURES WHEN NO HEAT STORAGE TANK IS CONNECTED The following operational procedures should be followed, especially when the boiler has excess capacity, (as it will have during milder weather): 1. Load the boiler with wood at least 3 times a day. 2. - Page 51 PERATING OILER (continued) PAGE 46 ______________________________________________________________________________________________________________________________________________________________________________________ OPERATIONAL PROCEDURES WHEN A HEAT STORAGE TANK IS CONNECTED The following operational procedures should be followed when the TARM EXCEL is installed with a heat storage tank system from TARM USA, INC. The use of heat storage system with a TARM EXCEL boiler yields increased operating flexibility and allows you to easily extend the wood heating season and the boiler burns at full output with the cleanest and most efficient operation.

Page 53: Heat Output
PERATING OILER (continued) PAGE 48 ________________________________________________________________________________________________________________________________________________________________________________________ HEAT OUTPUT The Tarm EXCEL is designed to operate in an output range from as low as 17,000 BTU’s per hour to a maximum of 102,500 BTU’s per hour (140,000 on EXCEL 2200). At maximum output, the fan will operate continuously. -
Page 54: Shutdown Procedures
PERATING OILER (continued) PAGE 49 SHUTDOWN PROCEDURES If you are not firing the Tarm EXCEL for any extended time periods (such as the summertime), you must maintain the boiler temperature at 140° F in order to prevent condensation and corrosion. If you cannot maintain boiler temperature, then you must protect the boiler by taking the following steps: 1. -
