F. SYSTEM COMPONENT CONNECTION AND SCHEMATICS
CONNECTION TO FORCED AIR FURNACE:
FORCED AIR GUIDELINES:
A water/air coil may be added to some forced air furnaces or blower cabinets to serve as the primary source of heat. When the room thermostat demands heat, water from the GARN® unit is circulated through the coil and the blower moves air through the coil. In a dual-fuel installation, the thermostat will activate the auxiliary heating unit if there is insufficient heat from the GARN® storage tank.
When adding a water/air coil to any forced air furnace:
DO NOT relocate, modify or rest any of the safety controls in the original furnace installation. Blower pulleys and motor pulleys may be changed, but the electrical current flowing through the motor is to be maintained within the nameplate rating. Under some circumstances a larger motor may have to be installed. Any water/air coil added to the system must be installed in accordance with the instructions of the manufacturer and in a manner acceptable to the regulatory authority by mechanics experienced in such services.
