NOTICE: To achieve proper combustion and the efficiencies listed in sales brochures, instruments must be used to secure CO2 or O2 readings.

3. Adjustment Of Heat Input Rate:

This appliance was shipped from the factory with one, fixed, main burner nozzle sized to produce the input rate using no. 2 fuel oil at 145 psi. The input rate cannot be increased.

The main burner oil nozzle for this unit was selected based upon the following assumed characteristic values of the fuel oil suitable for use with this appliance design:

1.For no. 2 distillate fuel (domestic heating) oil having a higher heating value of 140,000 BTU per gallon and a specific gravity of 0.88 @ 60ºF. (or “gravity” of 30º API @ 60ºF.).

4.Setting Supply Air Temperature Rise:

: To avoid injury from moving parts or electrical shock, shut off the power to the appliance before removing supply air blower compartment door and servicing this appliance.

The OHC is designed and wired at the factory for a blower speed during heating that should result in an approximate temperature rise of 60°F. The temperature rise through the heating section, for any given blower speed, may vary depending on a number of factors. A few of these factors are variations in, the actual resistance of the duct system to airflow at any time, the return air temperatures, and the fuel oil heating value.

Also, fouling of the heat exchanger surfaces will reduce temperature rise. In general, a lower temperature rise through the heating section will result in higher heating efficiency.
