Page 8: Installation
Installation Your WoodMaster Mini Boiler must be installed by a professional and should follow all local, state and fed- eral laws and regulations. Any use of an unapproved installation may result in a voided warranty. It is recommended to have your installation approved by WoodMaster. The Owner/Operator is responsible for operating the boiler in a manner that does not create a nuisance condition. - Page 9 Installation Water Lines The following layouts are a basic configurations for the boiler water connections. Contact your WoodMaster dealer or Northwest Manufacturing for additional installation variations. Insulate the lines to prevent heat loss. 1” oxygen barrier line is recommended. The boiler can be plumbed as a primary loop or a primary secondary loop.
- Page 10 Installation An expansion tank must be installed on the system along with an air bleeder. It is recommenced to install a pressure relief valve on the boiler, and an air bleeder or pressure relief valve on the water tank. A pressure gauge should also be installed on the boiler.
- Page 11 Installation After the installation of the WoodMaster add-on water to air exchanger, the air flow may need to be increased to fuel boilers, electric boilers, and electric/gas boilers. Methods of doing this are: Belt Drive System Blower pulleys and motor pulleys may be changed but the electric current flowing through the motor shall not exceed the nameplate rating.
- Page 12 Installation Renovator Pellet Burner Installation Install the mounting bracket to the boiler with the supplied hardware. The holes on the frame are slotted to allow adjust- ments for proper alignment. Use fiberglass rope or similar material to create a gasket between the boiler mounting plate and the burner mounting bracket (a gasket may have already been installed at the factory).
- Page 13 Installation 800 Watt Igniter Wiring 800 watt igniters need a dedicated 120v power source, that is routed through a relay on the side of the com- bustion fan. NOTE: Disconnect all power during installation. The black wire from the igniter is already connected to the relay, along with two wires from the PLC.
- Page 14 Installation Place the cover over the burner and secure it in place using the four thumb screws provided. Connect the wires to the burner. The Renovator Pellet Burn- ers have very simple connections that allow for easier re- moval for cleaning and maintenance. A.
- Page 15 Installation Feed Auger Installation The angle of the auger should be between 43 and 45 degrees. The auger can be hung from the ceiling or over- head support with a chain. The feed auger should be placed so that it does not sit right above the tipping chute on the burner.
- Page 16 Installation 5. Slide the inlet pipe over the auger tube. The hole in the inlet pipe should be 180 degrees towards the outlet on the T-pipe. 6. Fasten the screw shown to lock the inlet pipe in place. 7. Slide the blue tube to the outlet of the T-pipe, and the cap on the end of the inlet pipe.
- Page 17 Installation 2. Stand the side hopper upright. Attach the leg sup- ports ensuring that the longer of the three supports is on the side of the hopper that faces the boiler. Note: Install the supports on the inside of the legs, securing the supports to the legs with the “U”...
- Page 18 Installation 6. Raise the leg supports to a point just below the intake auger tube. Tighten the “u” bolts on the leg sup- ports to secure the legs to the leg supports. Fill the side hopper with wood pellets and prime the auger follow- ing the directions on page 20.
- Page 19 Installation Place the lid of the hopper on the hopper when assem- bly is complete. DO NOT remove during operation. Proper Boot Alignment Once the hopper is assembled put it in place next to the boiler. The bottom is adjustable to allow for easy installation of the auger tube.
- Page 20 Installation On Board Air Cleaner Installation The Renovator Pellet Burner has the capability to clean the fire pot with compressed air supplied by an on board air compressor. This allows for easier ignition as well as lower maintenance. Below is a brief explanation of the installation process.

Installation 5. Connect the air hose to the air compressor via the quick connect. Make sure the air compressors power switch is left in the “on” position. NOTE: Do not modify the length of the air hose. 6. Plug the supplied air compressor power cord adap- tor into the burner. -
Page 22: Operation
Operation The burner is not adjusted from the factory. The burner has to be adjusted with a flue gas instrument the first time the burner is fired and after a change in fuel brand/quality. 1. Remove the blue hose from the burner prior to priming the feed auger. Connect cable of the auger with the power cable for the burner and run it manually until pellets have been fed out from the auger for about 15 minutes using a bucket or pail to catch the pellets. - Page 23 Operation In phase two, the soft start level, the auger feeds the burner 5 times with three second operation intervals on the SOFT START auger before it goes over completely to full burn mode.

Page 26: Maintenance
Maintenance Note: You should clean the boiler on an “as needed” basis, typically once a week. Not all wood pellets burn the same, some may require you to clean the boiler more frequently. Your warranty does not cover ash cor- rosion. - Page 27 Maintenance Disconnect the red air line from the air compressor by pushing in the blue collar on the fitting, while pulling out on the hose. Disconnect the white wire for the igniter, and remove the black igniter wire from the relay on the side of the fan.
- Page 28 Maintenance Carefully slide the entire burner assembly out of the firepot. Release the quick latches that hold the sections togeth- er. Be careful as to not damage the gasket between the sections. Slide the inner part of the burn pot out of the outer sleeve.
- Page 29 Maintenance Clean any buildup out of the burn pot, and clean all debris out of the air holes. Once clean, insert the inner part of the burn pot into the outer sleeve. Ensure the alignment pins line up. When reassembling the burner, line up the four align- ment screws that align the sections together with the gasket in place.
- Page 30 Maintenance To partially remove the burner: Release the quick latches that hold the sections togeth- er. Be careful as to not damage the gasket between the sections. Slide the inner part of the burn pot out of the outer sleeve. Clean any buildup out of the burn pot, and clean all debris out of the air holes.
- Page 31 Maintenance Once clean, insert the inner part of the burn pot into the outer sleeve. Ensure the alignment pins line up. When reassembling the burner, line up the four align- ment screws that align the sections together with the gasket in place. Then latch the quick latches. Repeat the reset of the removal process in reverse to reassemble the burner.
- Page 32 Maintenance Slide each turbulator up and down to loosen. Insert a J hook into the chuck of a drill and hook the handle of the turbulator into the J hook. With the drill in a me- dium drive setting that will allow the drill to ratchet, slowly start spinning the turbulator while moving it in an up and down motion.
- Page 33 Maintenance Vacuum all ash from the tube box, including the door and any remaining ash in the heat transfer tubes. Make sure the turbulators are in place and close the top door when cleaning is complete. Open the ash box door by unscrewing the two knobs. Carefully remove the door and slide out the ash box.
