PROPER BURN PRACTICES FOR MAXIMUM EFFICIENCY AND SAFETY! • The chimney is one of the most important elements of the furnace. If the chimney is not connected properly and installed according to manufacturer’s specification and national and local codes, the unit is not safe and will not burn efficiently. Lack of proper chimney installation will cause unit to produce more smoke and less heat output. See Pages 5-10 of this manual to ensure proper installation.
SHELTER INDOOR FURNACE MANUAL MODEL: SF1000E EPA Certified to the NSPS 2020 Warm Air Furnace Requirements. SAVE THESE INSTRUCTIONS Congratulations! You have selected the finest quality wood burning indoor furnace, manufactured with pride in the USA. Please take a few moments to carefully read the owner’s manual. By taking the time to familiarize yourself with your new Shelter Furnace, you will be able to look forward to years of trouble-free, dependable service. Installation: First: Check local codes.
General Information The Shelter 2020 EPA-Certified Furnace has been engineered to accommodate the heating requirements of the average sized home, even during winter’s coldest months. It is constructed with high grade, heavy gauge steel and is continuously welded to assure the highest structural strength. In addition, the firebox is lined with insulated stainless steel panels to ensure many years of energy efficient service.
Location and Installation NOTE: Before beginning installation, consult proper local authorities regarding local codes governing all such applications and installations. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. Your furnace must be placed on a noncombustible floor. Position the furnace as close to the chimney as possible. Air for combustion must be provided into the room where the furnace is located. Allow air free access to the furnace for combustion and ventilation.
Assembly of Unit Please review the parts list and diagrams contained on pages 16-17 of this manual. DOUBLE CHECK TO MAKE SURE YOU HAVE RECEIVED ALL OF THE REQUIRED COMPONENTS.

Secure the flex conduit to the side of the furnace using the brackets with #8 screws (provided). 9.
CHIMNEY HEIGHT REQUIREMENTS The chimney must extend at least three feet above the highest point where it passes through the roof surface and at least two feet higher than any part of the building within a horizontal distance of ten feet. The termination cap should be designed to inhibit down-drafting without restricting the exhaust discharge. • When installing into an unlined brick chimney, lining the entire chimney with stainless steel chimney liner is strongly recommended.
Installation of Ducting • Proper ducting of the Cold Air Return and Warm Distribution Air is critical to ensure comfort throughout your home. • Consult a local HVAC contractor for assistance with the design and installation of effective ducting. • The furnace may be installed as a Dedicated System with separate cold/warm air ducting or an In-line System sharing the ducting of an existing central furnace. Careful consideration is required for both installations.
The add-on unit should only be installed on a furnace duct system and chimney that are in good operating condition. If exhaust fans are installed in the storage area they should not create negative pressures in the room where the solid fuel-burning appliance is located. On a belt-driven system, blower and motor pulleys may be changed but the electrical current flowing through the motor cannot exceed the nameplate rating.
CAUTION: • INSPECT FLUE PIPES, JOINTS, AND SEALS REGULARLY TO ENSURE THAT SMOKE AND FLUE GASES ARE NOT DRAWING INTO, AND ARE NOT BEING CIRCULATED BY THE AIR-CIRCULATION SYSTEM. • CLEANING OF THE HEAT EXCHANGER, FLUE PIPE, CHIMNEY, AND DRAFT INDUCER (IF USED), IS ESPECIALLY IMPORTANT AT THE END OF THE HEATING SEASON TO MINIMIZE CORROSION DURING THE SUMMER MONTHS CAUSED BY THE ACCUMULATED ASH. • Never use chemicals or gasoline to start or maintain your fire.
NEVER operate the furnace with the fuel door or ash door open! NEVER operate the furnace with the ash pan left inside of the unit! First Fire: Set the wall thermostat to 90°F. Place several crumpled newspapers on the grate with some dry kindling layered on top of the papers, then ignite the newspaper and close the fuel door. After approximately 5 minutes, open the fuel door, add several small pieces of wood and then close the door.
because if the ash pan is allowed to remain inside the furnace during operation, it will become dangerously hot to touch, block the flow of air under the grates and reduce the efficiency of the furnace. Remove the ashes from your Shelter Furnace at least once a day, or as often as necessary to ensure the ashes do not accumulate to the height of the grates. If ash build-up occurs at grate level, it will cause premature failure of the grate system, voiding the warranty on the grates.
NOTE: OVER-HEATING OR DELIBERATE ABUSE CAN EASILY BE DETERMINED UPON INSPECTION AND WILL VOID THE WARRANTY. Always burn seasoned wood. Dry wood will produce a higher BTU output and a longer burn time. Refer to the nameplate on furnace for additional information.

WARNING: RISK OF FIRE • DO NOT operate with the flue draft exceeding .08 water column inches (19.9 Pa).

Troubleshooting 1. 2. 3. Problem: Circulation blower runs constantly. NOTE: Make sure the white button on the fan limit control is pulled out and in the “auto” position. Possible Causes: Remedies: • Fan limit control is in “TEST” mode: white button is pushed in. • Pull white button out into the “AUTO” position. • “OFF”setting on fan limit control is low. • Remove cover on fan limit control and check for the proper setting. The point indicators should be set at 100°F “OFF” and 150°F “ON.
4. 5. 6. Problem: Draft blower will not run. NOTE: Verify that the wall thermostat is in the “HEAT” position, and make sure batteries are installed. Possible Causes: Remedies: • Defective wall thermostat. • This can be checked by turning the thermostat to a temperature setting that is higher than the temperature in your home, If the draft blower does not operate, the thermostat may be defective. Replace it if necessary. • Wall thermostat is in the wrong position.
7. 8. Problem: Draft blower runs constantly. Possible Causes: Remedies: • Defective wall thermostat. • This can be checked by turning the thermostat to a lower temperature setting than the temperature in your home. If the draft blower continues to run, the thermostat may be defective. Replace it if necessary. • Defective relay or transformer. • Replace relay or transformer, as necessary. • Home is not being supplied with a sufficient amount of heat to satisfy the wall thermostat.
9. Problem: Down draft on chimney caused by one or more of the following. Possible Causes: Remedies: • Flue has a cold spot which inhibits exhaust discharge from rising properly. • This problem may occur in factory built flues because the insulation has settled or a seam has ruptured. In masonry flues, mortar loss may be causing seepage of cooler outside air into the stack. Check entire flue for structural integrity and leakage. Correct or repair as needed, or replace or re-line the chimney.
12. Problem: Home does not achieve comfortable temperature. Possible Causes: Remedies: • Improper ductwork connection to existing furnace. • Refer to information in the manual relating to the proper installation procedures or contact your local heating and cooling contractor. • Improperly sized ducting. • Refer to information in the manual relating to the proper ducting procedures or consult your local heating and cooling contractor. • Excessive dirt accumulation in air filter.
