HE Series Outdoor Furnace Blower Replacement Instructions
HE Series Blower Replacement Instructions
These instructions are meant as a guide for replacing both the solenoid and the blower fan at the same time. It is not always necessary to replace both components at the same time. Use gloves and safety glasses.
- Blower (HS35 – HE-1100, HS36 – HE-2100)
- Gaskets (1100-DRG, 1100-DFG or 2100-DRG, 2100-DFG)
- Solenoid (HS33)
- Cotter Pin 5/32 x 2 1/2 (15640)
Tools: 5/16” hex driver
- Shut off power to the unit.
- Remove cover from the front door of your outdoor wood furnace by removing screws using the 5/16” driver.
- Remove the tape and wire nuts from the wires.
Wiring: White to white – neutral – solenoid
Gray to black– neutral – blower
Black to black – power/positive – solenoid and blower
Green – ground to door
- Remove screws from the solenoid.
- Remove cotter pin and draft plate (if changing to new solenoid).
- Replace cotter pin and draft plate (if changing to new solenoid).
- Remove airbox screws.
- Remove blower screws.
- Replace blower with new gaskets. It may be necessary to clean the door to remove the old gasket or silicone. (You can order a replacement door seal/gasket HERE). The new blower will have the wires tucked into the metal wiring box. Remove the screws and one knock-out in the blower. Feed the wires through the knock-out and replace the cover. It is recommended that the wire protector nut is also moved from the old blower to the new one.
- Replace the airbox.
- Replace the solenoid with the draft plate attached.
- Check for gaps or spaces between the blower to the door and the blower to the air box. If there are gaps the blower and air box need to be adjusted. Check that the solenoid draft plate fully covers the opening into the top of the airbox.
- Rewire the components. Solenoid wires should be between the solenoid and the door.
- Replace the cover.
- Turn on power and check (listen) for blower and solenoid.

Operating Furnace FAQs:
- Am I burning too much wood?
You may be. Is the wood properly seasoned? Have you cleared the firebox? High wood consumption can be caused by a number of factors.
- Can I leave my Outdoor Wood Burner over the weekend?
You may have someone "feed" your furnace for you or you may lower the thermostat temperature.
- Should I turn my thermostat down at night?
No, the lower the water temperature will cause the use of more wood to recover.
- What are the critical items to operate and maintain my furnace efficiently?
1. Keep water full
2. Manage ash
3. Use water treatment
4. Use seasoned wood
5. Keep fire in the middle of the firebox
6. Clean tubes regularly
- Why is water treatment important?
The chemical (water treatment) coats the inside of the furnace to reduce the effects of corrosion on the metal. Click HERE to order our Liquid Armor Water Treatment and other outdoor wood furnace parts.
- How often do I need to Inspect my Chimney/Flue
Inspect chimney and flue monthly and clean as needed. Clean chimney and flue annually. Perform cleaning and maintenance only when no fire is present in the firebox and ashes are cooled completely.
- How Can I Change the Door Rope Gasket of My Outdoor Wood Stove?
The rope will settle in the first few months of use. Before you change the rope gasket try adjusting your door. This is easiest with two people, one to push the door against the chute and the other to adjust the bolts. Keep your door snug but not so tight that it is difficult to operate.
- Why is ash management important?
If the ash becomes wet it is corrosive to the metal of the furnace. If the level of ash is too thick in the water box it does not allow for efficient heat transfer to the water in the water jacket of the furnace. The temperature of the water in the jacket is used to heat your house.
- Why am I not getting hot water?
Check that the hot water system is connected properly. Check if the heat exchanger is partially or totally clogged.
- Why does my furnace continue to burn when it is not operating?
Check the door seal, door adjustment, and solenoid.
- I can't find a leak in my furnace. Why am I losing water?
Outdoor Wood Burning Boilers use a non-pressurized system, this means that the existing heating system is exposed to the air. Since the water in the system can and will be warmer than the air, there will be evaporation of the water in the system. The water must be checked and adjusted at least once a month, sometimes more.
Be the HERO to your family and Be Prepared so you can keep your family warm and toasty while saving from your heating bills and avoiding the expense of costly repairs for your outdoor boiler.
