Congratulations, You have just purchased the finest wood / coal boiler available. Harman Trident boilers are constructed of high quality materials and are manufactured by a highly skilled team of assemblymen. Each boiler is inspected and pressure tested for quality assurance. This manual is designed to provide all of the basic information needed for a safe and proper installation. However, there are many skills needed that can not be learned by reading this manual.
Packing List The Following items are supplied with your Harman Trident Boiler: Please notify your Harman Dealer if you are missing any items. -- Shaker Handle --Johnson Controls Aquastat - (3) pieces; A350 Controller w/ Sensor wire S350 Stage Module Y350 Power Supply --Immersion Well --Din Rail and (2) End Clamps --Terminal Box --Terminal Block and (2) #8-32 nuts --Pressure Relief Valve (30 psi.) --Temperature / Pressure Gauge --Automatic Draft Control Assembly --(1 pc.
Installation Getting Started The sheet metal sides and top are easily removed to reduce the chance of dents and/or scratches in the finish. Simply lift the top off, and that will allow the sides to be pulled away and up, for removal. To re-install, slide the channel, at the bottom of each side piece, over the lip at the bottom of the boiler, and hold downward while moving the side panel into place. Then slide the top down over the sides.
Installation Bolt the Automatic Draft Control through the 1/2 in. hole in the center of the bottom door. Be sure to hold the Draft Control straight while tightening. Feed the two wires from the draft motor through the flexible conduit and a 90˚ fitting. Secure the fitting to the draft motor and that end of the conduit at this time. Check the flapper door on the Automatic Draft Control assuring that it moves freely. Install the (3) brass coil spring handles onto the door latches and the shaker handle.
Installation Wiring and Electrical Optional Items There is a domestic hot water coil available for your Trident Boiler. The coil installs in the front of the boiler, and allows your domestic water to be heated by the heating system water. Install the coil now, by removing the round plate and replacing it with the coil and it’s round plate. Be sure to tighten the bolts evenly, to ensure a good seal. If electric back-up is desired, install now.
Installation Plumbing 3 feet (0.9m) above the point at which they exit The Harman Trident Boiler can be used as from the roof, it must also extend 2 feet (0.6m) above the highest point within a 10 ft. (3m) radius. a “Stand Alone” boiler or as an add-on to an existing hot water heating system. Do not connect this unit to a chimney The diagrams in this manual are meant to flue that is serving another appliance. show the necessary equipment and piping. Your system may look very different.
Installation The circulator installed between the two boilers may be hooked up to run continuously during the heating season or, an additional S350 control (not supplied) could be installed to turn it on and off automatically. This control must be used as a “close on rise of temperature” (jumper in cooling position). Harman Stove Company recommends that 1-1/4 in. pipe be used between the two boilers.
Operation Automatic Draft Control The heat output is regulated by the automatic draft control on the bottom door. The electric motor (A) opens and closes the flapper door (B). Opening and closing the flapper door regulates the air flow into the firebox. The maximum air flow can be adjusted by turning the adjusting bolt (C). Turn counterclockwise for more air, and clockwise for less air. Adjust this bolt only while the flapper door is in the closed position. Otherwise, motor damage could occur.
Operation Starting a Coal Fire Loading should cause the automatic draft control to open. Open the ash pan door to allow free air movement. Use the same procedure as starting a wood fire except, do not load the larger diameter wood Use wood about 2 in. diameter maximum. This size will form a very hot charcoal bed in less time. Again, the ash pan door may be opened periodically to speed the ignition process. Do not leave the boiler unattended with any door open.
Operation Safety Tips When opening the firebox door, it should be cracked, slightly open, for a few seconds to allow air in to burn any gases which may be present. This will also allow smoke to be drawn away from the door. Whenever the ash pan door is open, it should be closed before opening the firebox door. During the first few hours of burning, a blue smoke may be observed rising from the boiler. This is the paint going through the curing process.
Maintenance Maintenance The spiral chamber is basically self-cleaning. However, if there is a draft problem and you have been burning wood for a long time with little demand, the spiral chamber will need to be cleaned. To clean the spiral chamber, remove the stovepipe and scrape any creosote or debris from the top and front of the chamber. The rear of the chamber should not have much accumulation. If it does, clean it out. NOTE: 1/4” to 1/2” of creosote in the spiral chamber is normal.
