HOW THE FURNACE FUNCTIONS

RULES FOR SAFE INSTALLATION AND OPERATION

14.CARING FOR PAINTED PARTS - This furnace has a painted outside jacket, which is durable but it will not stand rough handling or abuse. When installing you furnace, use care in handling. Clean with soap and warm water when furnace is not hot. DO NOT use any acids or scouring soap, as these wear and dull the finish. DISCOLORATION WILL OCCUR IF THE FURNACE IS OVERFIRED. FOLLOW OPERATING INSTRUCTIONS CAREFULLY.

15.Keep the feed and ash doors closed at all times except while tending the furnace.

Your Furnace is designed to be installed in a parallel air flow arrangement with a gas or oil-fired forced air upflow-type central furnace, or it may be installed as a central furnace.

HOW THE FURNACE FUNCTIONS

Your Ashley Furnace is designed to be a supplemental or central heating source for your home. This solid fuel furnace may be installed in conjunction with a properly operating central fur- nace that is listed or certified in accordance with nationally recognized safety standards and equipped with the required controls and other safety features and which has been installed with appropriate standards of National Fire Protection Association with installation clearances specified in the furnace nameplate marking. The installation must be accomplished by a qualified agency (one who is engaged in, and is responsible for, or is thoroughly familiar with the installation and opera- tion of the gas, oil, and solid fuel burning heating appliances, who is experienced in such work, familiar with all precautions required, and has complied with all the requirements of the authority having jurisdiction.) The installation shall be in strict accordance with the manufacturer's installa- tion instructions furnished with the solid fuel fur- nace.

The chimney connector of the furnace is to be installed to provide clearances to combustible material not less than specified in the individual classifications and marked on the furnace. The chimney connector must be connected to a chim- ney suitable for use with residential type or building heating appliances which burn solid fuel.

The furnace is designed to operate in either parallel or series air flow arrangement with the central furnace or as a central furnace.

CENTRALFURNACEINSTALLATION:As a cen- tral furnace, the unit functions independently of any other system. The blower will come on when the plenum temperature reaches the setting on the blower control.

PARALLEL INSTALLATION: The design is such that when the blower comes on, the blower on the central system also comes on.

The blower will only come on when the temperature in the plenum has reached the setting on the blower control. This is to insure that there is sufficient warm air in the system to make it efficient for the unit to operate. When the central system thermostat calls for heat, the central sys- tem will operate by the burner igniting and the blower coming on. It is possible that both systems will operate simultaneously. It is recommended that for the most efficient use of your Ashley Furnace, that it be fired as much as possible in order to reduce the demand on your existing central heating system. This unit has an Optional forced draft kit that operates from a wall thermostat. When the temperature falls below the setting on the wall thermostat, the forced draft will come on. (U.S. Stove Option 11 DIK)

The warm air supply outlet of the Ashley furnace shall not be connected to the cold air return inlet of the central furnace because the possibility exists of components of the central furnace over- heating and causing the central furnace to operate other than is intended.

SERIES INSTALLATION: (U.S. & CANADA) This type of installation uses only the blowers of the existing central furnace. The solid fuel fan/limit control must also control the functions of the existing furnace. All electrical power must come from a single branch circuit.
