A.3 Start Up
Use following instructions to set the burner:
1.
Shut off electrical power to the furnace.
2.
Install oil pressure gauge to pressure port on oil pump.
(Refer to oil pump specification sheet included with burner
instructions).
3.
Restore electrical power to furnace.
4.
Start furnace and bleed all air from fuel oil lines.
5.
Close purge valve and fire the unit.
6.
Allow furnace to warm up to normal operating temperatures.
During this time, set pump pressure in accordance with data
provided in Appendix A, Table A-1 thru A-3.
7.
Chimney vented units
- Drill 1/4" test port in venting
between furnace flue outlet and draft regulator (barometric
damper) to take smoke readings.
8.
Direct vented units
- Do not drill. Use test port in furnished
appliance connector to take smoke readings.
9.
When furnace has reached "
steady state
" (after
approximately 10 minutes), set combustion air damper to get
TRACE of smoke for chimney vented units.
10.
Check system temperature rise.
Temperature rise is the
difference between return air temperature measured at
a point near return air inlet, and supply air temperature
measured near furnace outlet
.
System temperature rise is listed on furnace rating plate. If
temperature rise is too high, airflow must be increased. If
temperature rise is too low, slow fan down.
11.
Chimney vented units -
after air adjustments have been
completed, recheck the breech draft. Breech draft should be
adjusted to -0.02 inches w.c.
12.
Turn burner off. Observe duct thermometer in supply air
stream, note temperature blower fan stops. Fan adjustments
can be made by moving dipswitch settings on timer control
board for fan off delay.
13.
Check operation of limit switch.
A. Shut off power to furnace.
B. Temporarily remove neutral wire from PSC blower motor
or from neutral terminal on fan timer control, or remove
5 pin power connector from ECM blower motor. Isolate
AC line voltage pins on 5 pin power connector with
electrical tape to prevent electric shock hazard.
C. Restore electrical power to furnace.
D. Set thermostat above room temperature.
E. After two or three minutes of burner operation, limit
control should turn burner off.
F. When limit function test is complete, shut off electrical
power to furnace, replace neutral wire or 5 pin power
connector. Restore power.
G. Blower fan will start up immediately. Once temperature
has dropped and limit control has reset, fan will operate
until fan off time is reached.
H. Oil burner will resume operation and continue until
thermostat is satisfied.
I. Restore thermostat setting to comfortable temperature.
14.
Set heat anticipator adjustment in thermostat (if so
APPENDIX A - CHECK OUT AND ADJUSTMENTS
equipped), by removing "R" or "W" wire to thermostat. Read
amperage draw between the two wires. Failure to remove one
of the wires from thermostat while performing this test could
burn out heat anticipator. Set heat anticipator to amperage
measured.
15.
Direct vented units
- Check all joints in positive pressure
venting system for leaks before leaving site.
16.
Run furnace through at least three full cycles before leaving
installation, to ensure all controls are operating properly.
A.4 Final Check Out
Verify all safety devices and electrical components have been set
for normal operation.
Verify all electrical connections are tight and wiring is secure.
Verify homeowner is informed and understands:
• Where circuit breaker or fuse is located in main electrical
panel.
• Where furnace switch is located, and switch "on" and "off"
positions if not obvious.
• Where oil shut-off valve from oil storage tank is located.
• Thermostat operation, and other related accessories.
• How to operate manual reset button on primary control, and
when not to push the reset button.
• How and where to visually inspect venting system for leaks or
other problems.
•
How to inspect, clean and replace air filter, and other
homeowner maintenance procedures.
• Who to call for emergency service and routine annual service.
