GENERAL
All furnaces have been fire-tested to check for
proper operation. This includes main burner flame, pilot flame,
and gas control operation. If the furnace fails to function on initial
installation, it is advisable to re-check the following:
1.
Inlet gas pressure.
2.
Type of gas being used and that shown on the rating
plate.
The Service Department at Empire Comfort Systems, Inc. may be
contacted to assist in servicing furnace.
Servicing the Pilot and Main Burner, Pilot Orifice, Thermopile
and Main Burner Orifice
Disconnect the gas supply at the inlet to the control valve.
Remove the burner assembly to which the above components
are attached.
Pilot Does Not Light
With air in the gas line, such as when the furnace is first installed
or was "OFF" all summer, the pilot flame may be too lean to
ignite on the first few trials. Turn the gas control knob to PILOT
position and depress the gas control knob. Hold the gas control
knob down to bleed the line;
1.
Use lighter rod to light pilot with a match.
If Pilot Does Not Light By Any Means
1.
Check gas control knob for being in the "Pilot" position.
2.
Check pilot adjustment for being full open (counterclockwise
to open).
3.
If gas is available in the supply tubing, the pilot orifice
and/or pilot burner is probably restricted by a spider web.
Clean pilot assembly and relight.

millivolts when wall thermostat or remote bulb is turned
OFF.
Replace gas control if magnet dropout millivolt
reading is over 100 millivolts.
