Hawken Furnaces by OutdoorBoiler.com Startup Procedures
Please observe the following steps when starting the furnace:
- Observe all safety precautions
- Ensure that the installation has been completed properly.
- Make sure the outdoor wood furnace is full of water. Verify this with the water level indicator AND by filling the furnace until water flows out of the vent tube on the roof peak.
- Make sure the outdoor boiler water has been properly treated with authorized outdoor boiler water treatment. Click HERE for our Liquid Armor Water Treatment.
- Open all valves. Allow 5 minutes for the water to fill the circulating pump and the heating system.
- Turn on the power and make sure the boiler pump is running. Never operate your outdoor wood stove without the pump fully circulating water.
- Make sure the fan switch is operational. The fan switch is located on the front of the furnace under a flip cover. Turning the fan switch to the ON position (up) will turn off the loading light, and turn on the blower fan in the door. Turning the fan switch to the OFF position (down) will turn off the blower fan, and turn on the loading light.
- Set the Aquastat located in the rear of the outdoor wood stove (towards the top) to 180 degrees F. Remove the grey cover to the Aquastat and verify that the temperature differential dial (on the right side) is set to 20. This will cause the furnace to automatically shut off the blower fan when it senses furnace water temperature of 180 degrees, and turn on the blower fan when the water temperature drops to 160 degrees.
- Build a small fire in the firebox, and allow the outdoor wood boiler temperature to rise SLOWLY.
- When the temperature reaches 170 degrees, the outdoor wood burning boiler is ready to be filled to capacity for full operation.
