Temperature rise = supply air temperature - return air temperature.

After 15 to 20 minutes of continuous operation, the temperature rise through the furnace must fall within a range of 55° to 85° F. If the outlet or supply duct temperature is too high, check to make sure the return air filter is clean, the return air registers are free from obstruction, the outlet registers are properly adjusted and clear, and the supply and return air ducts are open. The circulating air blower is not moving enough air if the supply air temperature is still too high. Before proceeding further, turn off the power supply to the appliance and remove the vestibule cover. The speed of the blower must be increased by changing the switch setting on the control board, please refer to Table 6.

5. Checkout Procedure:

Before any system of oil piping is finally put into service, it shall be carefully tested to assure that it is “gas-tight”, as indicated in the Heating System Initial Startup section of this manual.

NOTICE: All controls on the unit should be checked for proper functioning prior to the qualified service personnel leaving the job site. Specifically the following should be checked:

a.With heating system in normal heating operation, check to make certain blower will start and stop automatically under control of the indoor thermostat.

b.Check safety limit control as follows:

i.Shut off incoming power.

ii.Block return air opening or disconnect blower motor leads.

iii.Restore power to appliance.

iv.In the heating mode, set the thermostat above room temperature producing “a call for heat”.

v.When high air temperatures are reached within the heating section, the high limit control should act to shutdown the burner.

vi.Shut off the electrical power.

IMPORTANT: Remove blockage or reconnect blower motor and restore power.

c. Make certain the thermostat will automatically start and stop the appliance.

NOTICE: Heat exchanger oil will burn off on initial firing creating an unpleasant odor. To prevent this odor from occurring more than once, it is suggested the heating section be allowed to run for 30 minutes, or until odor has dissipated.
