SF1000E Operator Manual | 1.2021

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. Unacceptably high temperatures will result because the ashes have restricted the flow of cooling air beneath the grates. This flow of air was designed to not only cool the grates, but to also provide warmed air for better combustion. If the ash level is improperly maintained the firebox will be starved of combustion ai , greatly reducing the efficiency and heat output of your Shelter Furnace. CAUTION: HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION.

IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES, DO NOT RETURN TO THE STORE OR TO THE DEALER. CALL 1-800-875-4788.

Draft Blower: The draft blower plays an important role in the operation of your Shelter Furnace. When the wall thermostat calls for heat, the draft motor turns on and supplies fresh air into the firebox producing a hotter fire, which in turns provides more heat in the heat chamb . The heat is then sent through the duct system throughout your home. When the wall thermostat temperature is met, the draft blower shuts off until the thermostat calls for heat, beginning the cycle again. Do not alter or adjust the draft blower in any manner. Creosote Formation and Need for Removal: When wood is burned slowly, it produces compounds in exhaust smoke which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cooled chimney flue of a slow burning fire. As a result, creosote residue accumulates on the flue lining When ignited, this creosote makes an extremely dangerous fire in the chimne . The chimney connector and the chimney should be inspected at least twice monthly during the heating season to determine if a creosote build-up has occurred. If creosote has accumulated it should be removed to reduce risk of a chimney fire. Creosote Prevention: To help reduce the formation of creosote within the flue, ALWAYS BURN DRY, SEASONED WOOD. Dry wood burns hotter, allowing flue gases to maintain temperatures above 212°F which should reduce the quantity of creosote in the chimne . If the flue gas temperature falls below 212°F, condensation occurs causing creosote formation and accumulation within the chimney. As an added precaution, periodic chimney inspections are recommended during the heating season to determine if creosote formation has occurred. For safety and efficienc , it is recommended that the chimney system be inspected and cleaned prior to each heating season. Chimney Fire Warning: In the event of a chimney fire, take the following actions immediately:

• DO NOT unplug the furnace. • Close the ash door, the fuel door, and slide the cover on the draft motor to Power Fail setting. • 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 Remove air filter and position cover on draft motor to Power Fail setting (see diagram on pg.15) There is no warranty on electrical components damaged due to power failure.
