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 7-9 of this manual to ensure proper installation.

General Information The Shelter EPA-Approved Furnace has been engineered to accommodate the heating requirements of the average sized home, even during winter’s coldest months, with a heat output range up to 140,000 BTUs. 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.
NOTE: For your convenience your Shelter Furnace has been factory assembled and the electrical control assembly pre-wired. 1. Fasten the right and left side angle brackets to the circulation blower using (4) ¼ - 20 bolts and nuts. Line up the blower with the predrilled holes on the backside of the furnace, firmly attach with the screws provided. Angle AngleBracket Bracket Bolt 1/4 Four -1/4-20 20Places Bolt 1/4-20 NutNut 1/4 - 20 2. Attach blower to the left and right mounting brackets.
3. Assemble the following parts using 6 #8 sheet metal screws. Both “B” panels should fit inside of “C” and “A” panel flanges. Attach “C” (bottom panel) to “B” (side panels). After the top and sides are assembled, attach ”A” (top panel) using 6 #8 sheet metal screws provided.
5. Plug motor into the back of the electrical control center. 6. Connect the thermostat wire (not included) to the 2 posts located on the side of the control center. For convenience, you might consider locating the wall thermostat next to your existing thermostat in your home. The thermostat MUST be installed for the furnace to operate. 7. Plug the 3 pronged grounded plug into a grounded electrical outlet..
For the best draw the chimney termination should be at least 2 feet above the highest point of the roof that is within a 10 foot radius of the chimney. The termination cap should be designed to inhibit down-drafting without restricting the exhaust discharge. When using a brick chimney, you must line the entire chimney with stainless steel liner. The liner must be the correct size for the furnace. (SF2600 and SF3100: 6” liner.
WARNING- RISK OF FIRE: • Do not operate with flue draft exceeding .08 water column inches (19.9 Pa). • Do not operate with fuel loading or ash removal doors open. • Do not store fuel or other combustible materials within marked installation clearances. • Inspect and clean flues and chimney regularly. DANGER: Risk of Fire and Explosion. Do not burn garbage, gasoline, naphtha, engine oil, or other flammable liquids/inappropriate materials.
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. On a direct-drive system, the motor should not be changed, however, the speed of the motor may be increased. The blower cannot be changed. This equipment should be installed, acceptable to regulatory authority, by experienced licensed personnel. Establish a routine for the storage of fuel, care of the appliance, and firing techniques.
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.
BURN WOOD ONLY! First Fire: Set the wall thermostat to 90°F. Make sure the switch for the draft blower is in the ON position. Place several crumpled newspapers on the grate with some dry kindling layered on top of the papers, then ignite the newspaper. When the kindling is burning, add several small pieces of wood, allow wood to fully ignite. After about 20 minutes the fire should be established, allowing you to add more wood – do not overload which would smother the fire.
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.
• • • • Activate and toss a Chimfex™ Dry Chemical Chimney Fire Extinguisher into the firebox. Close the ash door, fuel door and slide cover on the draft motor. Alert entire household and prepare to evacuate if necessary. Call your local fire department. Power Failure: In case of power failure, to prevent your Shelter Furnace from over-heating and causing damage to the electrical components, do NOT add more fuel to the firebox. There is no warranty on electrical components damaged due to power failure.

1. 2. 3. Troubleshooting Problem: Circulation blower runs constantly. NOTE: Make sure the white button on fan limit control is pulled out and in the “auto” position. Possible Causes: • “Off”setting on fan limit control is low. • White button on fan limit control is pushed in. • Pull white button out and the blower should stop. • Defective fan limit. • Check by moving “ON” and “OFF” point indicator to a temperature position where blower should turn off.
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: • Defective rocker switch on control center. Remedies: • Replace rocker switch. • 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 if necessary.
7. 8. 21 Problem: Draft blower runs constantly. Possible Causes: • Defective wall thermostat. Remedies: • This can be checked by turning the thermostat to a lower setting than the temperature in your home. If the draft blower continues to run, the thermostat may be defective. Replace if necessary. • Defective relay in transformer. • Replace transformer and relay. • 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: • Cast iron damper in “CLOSED” position. Remedies: • Open damper. • 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.
12. Problem: Home does not achieve comfortable temperature. Possible Causes: • Improper ductwork connection to existing furnace. 13. 23 • 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.
15. Problem: Cannot hear or detect changes in blower motor speed. Possible Causes: • Your motor has bearings so it runs smoothly and quietly. Remedies: • Refer to information in the manual on page 13 to understand the operation of the blower motor. Warranty Information CERTIFICATE OF LIMITED WARRANTY: EXTENT OF COVERAGE: This warranty covers any Shelter Furnace SF2600 and SF3100 sold in the United States and Canada.
