All installations and services must be performed by qualified service personnel.

In summary, setting the combustion air on the Thermo Pride Midco RE32 power gas conversion burner is extremely critical. This adjustment should only be made by following these instructions and confirming the set-up with the proper CO2 or O2 combustion analyzer and a carbon monoxide reading of less than 50 PPM.

L. REQUIREMENTS AND SIZING OF DUCT WORK

The duct system must be sized and installed by a qualified installer or service person, following the design standards of the Air Conditioning Contractors of America (ACCA) or ASHRAE.

1.When a return air register is located in the same room as the furnace, it must be installed a minimum of 20 feet away from the furnace.

2.If supply ducts carry circulated air to areas outside the space containing the furnace, the return air duct shall also be sealed to the furnace and also terminate outside of the furnace space.

3.The return air duct system must equal the supply air duct system in its CFM capabilities. Use a supplier's catalog for proper sizing of outlet and return air registers and grills to ensure that they meet the CFM requirements of the run to which they are connected.

4.If the furnace is used in connection with an air conditioning evaporator coil, the furnace must be installed parallel with or on the upstream side of the coil, to prevent condensation in the heat exchanger. If the evaporator coil is installed with a parallel flow arrangement, dampers or other means to control flow of air should prevent chilled air from entering the furnace. If such a device is manually operated, it must be equipped with a means to prevent operation of either the furnace or air conditioner unless it is in the full heat or cool position.

5.The duct system shall be sized for the maximum CFM requirement of the installation, whether it is for heating or cooling. Two common rules for heating and cooling follow:

A. 400 CFM (1200 BTU's) per ton of cooling is required.

B. 1.4 CFM of heating per 100 BTU's of furnace output based on its steady state efficiency and a 50° to 80° temperature rise.
