Thank you for choosing a CDL wood evaporator. Our 40 years of experience working with sugarmakers ensures you that you acquired a high performance, quality piece of equipment. Before using this product, make sure you understand all the following instructions. If there is any problem upon receipt of this product, please immediately contact CDL or your local representative. - Page 3 IMPORTANT: Make sure to contact your insurance company in order to verify their safety standards, and requirement for coverage. If your building is not insulated, you will have better combustion and better steam evacuation. If it is insulated, you will need to have an air intake inside your building (air trap, open window etc.) CDL Maple Sugaring Equipment inc.
- Page 4 INSTALLATION OF THE ARCH If your building is not insulated, you will have good combustion and a better evacuation of the steam. However, if it’s well insulated, make sure you have enough fresh air intake to have a good combustion and enough draft. 1. Remove the wheels under the evaporator. 2. Remove the pans. Level the arch using the adjustable legs. 3. When the evaporator is leveled, tighten the nuts on the legs. 4. The 2’ wide Venturi evaporator has a fixed Venturi system on the smoke stack. It only requires a 110 volt plug in. 5. All the Venturi evaporators, 2-1/2’ and wider have a Venturi system that can be installed remotely to lower the noise level. You just have to install an adaptor and enough pipe to hook up the blower to the smoke stack. Try to minimize air flow restriction by installing the blower as close as possible to the evaporator and by using long radius elbows if necessary. 6. The Venturi system must be hooked up in the first section of smoke stake on top of the base stack. CDL Maple Sugaring Equipment inc.
- Page 5 1. Start with the bottom between the grates and the front, sides and back of the arch. Leave 3/16” between the grates and the bricks for expansion. 2. Build the side walls, one row at the time. Make sure to lean the brick against the wool on each side of the arch. Here’s what the final product should look like: Front view Side view Close-up of the wall 3. Let the cement dry for 24 hours. 4. It’s now time to cure the cement and the bricks. Fill the pans with water as if you were going to boil sap. Start a fire and bring the temperature inside the burning chamber between 400°F and 500°F for an hour. Do not start the Venturi system during this operation. Also, do not exceed 500°F and make sure the pans don’t run out of water. Keep at least 2” of water in each syrup pan and at least 2” of water above the flues at all time. 5. Let the evaporator cool down for 24 hours. CDL Maple Sugaring Equipment inc.
- Page 6 ASSEMBLY The insulation and bricking are completed. Here’s how to put together the pans and stack. Base stack Connections Flue pan Rear float box Draw-off valve Sap entry Syrup pan (back of float box) Pan tightener Level Front float box Door Arch 1. Set the pans on the evaporator starting with the flue pan. Make sure the back of the pan touches the back plate (or the reheat pan if you have one). Then, install the syrup pans in the front. Make sure the evaporator and the pan are leveled. Finally, tighten the pans together using the pan tightener. 2. Install the float boxes, all the connections and the level(s). Hook the sap / concentrate line from the tank to the back of the rear float box. The bottom of the tank needs to be at least 12” higher than the maximum level in the evaporator. Don’t forget to put Teflon tape on the threaded parts to avoid leaks. 3. Install the base stack on the back of the evaporator. 4. Install the first section of smoke stack (the one with the Venturi system), on top of the base stack. 5. Install the roof jacks on the roof. Make sure you seal the installation properly to avoid leaks inside the sugarhouse. CDL Maple Sugaring Equipment inc.
- Page 7 The quality of the wood that will be burned is an important factor in the performance of the evaporator. Poor quality wood will reduce the boiling rate, you will fill the burning chamber more frequently and the maple syrup produced will be darker. See table 1 to find the heat potential for each type of wood. Table 1 Heat produced by each type of wood(Millions BTU per cord) White pine Sugar maple Red maple Spurce Beech Larch Yellow birch White birch Poplar CDL Maple Sugaring Equipment inc.
- Page 8 1. Make sure the outlet of the tank feeding the evaporator is at least 12” higher than the sap level in the flue pan and that the tank is hooked up properly to the back of the rear float box. 2. Install a syrup thermometer on each syrup pan. Make sure they are calibrated by dipping them in boiling water and adjusting the temperature at 0 degree. 3. Open the rope operated stack covers. 4. Open the sap valve from the sap tank to the evaporator. Fill the flue pan 2” above the flues. 5. Open the front float box valve and fill the syrup pans 2” deep by adjusting the float in the front float box. 6. After the start of the evaporator, using the float boxes, stabilize the level in each pan. We recommend 1” in the flue pan and between 1 ½” and 2” in the syrup pans. Light the evaporator 1. Lighting the evaporator is done with the Venturi shutoff. 2. Completely open the front grill. 3. Using small dry wood and paper, light the evaporator. 4. Wait until you get a good burn. 5. Fill the combustion chamber (1” from the pans). 6. Start the Venturi system. 7. Leave the Venturi system running at all time, even when you fill the chamber with wood. 8. Adjust the draft with the front grill. Try to maintain a base stack temperature of 750°F. CDL Maple Sugaring Equipment inc.

7. When you are almost done for the day, make sure you have enough sap left in your tank to fill all the pans 2” higher than the normal sap level. It will compensate for the evaporation that will keep on happening because of the heat accumulated in the evaporator until it cools down. If you have any questions, don’t hesitate to contact your CDL sales representative. IMPORTANT SAFETY NOTE: THE HEAT IN FRONT OF THE EVAPORATOR WHEN THE DOOR IS OPEN IS INTENSE. ALWAYS WEAR GLOVES, SAFETY GLASSES AND HEAT RESISTANT CLOTHING WHEN FIRING THE EVAPORATOR. CDL Maple Sugaring Equipment inc. -

Sap turns to syrup in the 1 syrup pan: • It can happen when you start the evaporator. Draw-off enough syrup to get it to the front and distribute what was drawn-off in the flue pan. This will get the movement forward going. The heat in the chimney is too hot; the base stack turned red or the evaporator doesn’t boil much: • Too much draft, gradually closed the front grill until the problem is fixed. If you have any other problem, contact your CDL sales representative CDL Maple Sugaring Equipment inc. -

Front pans have to be checked every hour to prevent overheating. If too much scale deposit in your pan, you could burn it. So make sure that you check your flue pan at the end of every day, especially in the corners at the end of each flue. Too much niter deposits can cause a pan to overheat. Under the pan and between the flues, use a flue brush to remove as much soot as possible. In between season storage 1. Put all your pans on wood blocks to let air circulate in the arch and under the pans. Too much humidity can cause damage. 2. Remove any deposits inside the pan with a good acid wash. If necessary, brush all the flues inside and outside with the appropriate brush and a pressure washer. Always make sure the flues of the pan are clean. 3. Never leave any kind of cleaning product in the pans, it will damage them and it’s not covered by the warranty; 4. O-rings must be greased with food grade grease (to prevent shrinking and drying) CDL Maple Sugaring Equipment inc.
