8. Obstruction at main burner orifice.
9. Break in wiring or loose contact at control terminals.
10. Improper wiring.
11. Improper controls.
12. Defective air flow pressure switch.
13. Rollout switch open.
BURNERS WILL NOT SHUT OFF
CAUSE
1. Defective operating control, gas valve, or high limit control.
FLASH BACK - BURNING AT ORIFICES
2. Improper wiring or short circuit.
CAUSE

2. Improper primary air adjustment.
3. Gas regulator bleed too slow.
4. Burrs on orifice.
5. Improperly drilled orifice plugs.
6. Leaking automatic gas valve.
7. Adverse draft condition in boiler room.
8. Low main gas pressure.
DELAYED IGNITION
9. Safety pilot improperly installed.
CAUSE
1. Pilot flame too low.
2. Pilot burner ports or pilot orifice clogged.
3. Burners or orifices out of alignment.
4. Excessive primary air.
5. Excessive burner input.
FUMES AND GAS ODORS
6. Adverse draft condition in boiler room.
CAUSE
1. Leaks in gas piping or accessories.
2. Gas leaks in service line or meter connections.
3. Blocked chimney.
4. Boiler flueways blocked with soot.
5. Undersized breeching or too many turns in breeching.
6. Adverse draft condition in boiler room.
7. Overfiring.
CONDENSATION IN BOILER FLUES OR IN VENT SYSTEM
CAUSE
1. Underfiring.
2. Boiler water maintained at too low a temperature level.
BURNER SHORT CYCLES
CAUSE
1. Thermostat heat anticipator set too high.
2. Excessive pressure drop in venting system.
3. Blockage or restriction in venting system.
4. Faulty air flow proving mechanism.
REMEDY
1. Check, clean, re-light. See instructions.
2. Open gas valve(s).
3. Close switch.
4. Replace fuse.
5. Check control. Clean contacts or replace control.
6. Repair or replace.
7. Replace aquastat.
8. Check, clean and reinstall.
9. Check with test-light and correct.
10. Check and correct in accordance with wiring diagrams
included with appliance instructions.
11. Install proper controls.
12. Check and replace if necessary.
13. Replace rollout switch (inspect flue passages prior to
replacement).
REMEDY
1. Check, repair or replace.
2. Check wiring and controls.
REMEDY
1. Adjust to proper manifold pressure.
2. Adjust air to produce soft, clean flame.
3. Adjust bleed opening.
4. Remove burrs.
5. Install orifice plugs with proper drilling.
6. Repair or replace.
7. Check air supply and venting system.
8. Contact utility.
9. Correct to manufacturer's recommendations.
REMEDY
1. Increase gas supply to pilot.
2. Clean ports or orifices.
3. Realign burners or manifold.
4. Adjust primary air shutters.
5. Check and reduce to input shown on rating plate.
6. Check air supply and venting system.
REMEDY
1. Locate leaks and repair.
2. Close service supply valve - shut down appliance and
notify utility.
3. Check and repair chimney.
4. Clean flueways and adjust burners as described in the
installation instructions.
5. Check manufacturer's recommendations.
6. Check air supply and venting system.
7. Adjust gas input to that shown on boiler rating plate.
REMEDY
1. Increase firing rate to that shown on rating plate.
2. Set low limit controls to maintain a higher water tempera-
ture. If boiler is not equipped with low limit replace with
one which has a combination low limit/high limit aquastat.
REMEDY
1. Reset anticipator to *amps.
2. Reroute and/or shorten venting system.
3. Check for blockage or restriction.
4. Consult factory.
