Restrictor Assembly and Installation
Burner flame appearance and characteristics are affected by altitude, fuel quality, venting configuration, and other factors. To achieve desirable flame appearance, the vent exhaust may be restricted by the restrictor plate (included in components packet).
The restrictor plate is shipped with all inner rings intact, and when installed, provides the most vent restriction. There are (2) inner rings that can be knocked out. The innermost ring knocked out will create less restriction, and the outer most ring knocked out will create the least amount of restriction.
Refer to section 11.2.2, VENT RESTRICTION (AFTER INSTALLATION) on page 45 outlines restriction recommendations depending on burner flame appearance, and instructions on installation after venting is completed.

TROUBLESHOOTING

ATTENTION: Troubleshooting must be performed by a qualified technician.

No spark from electrode to pilot when piezo button is triggered| Piezo igniter wiring disconnection| Verify piezo igniter is properly grounded. Tighten mounting fastener, if required.
Check and repair, if necessary, the wire connections between the piezo igniter and igniter electrode.
Check wiring disconnection| Check wiring at back of electrode igniter for proper connection.
Incorrect electrode position| Verify there is a 1/8” (3mm) gap between the electrode and pilot. Readjust if necessary. Direct metal contact may cause an arc below the electrode and along the electrode wire.
Spark igniter will not light after repeated triggering of piezo button| No gas| Check for multiple shut-off valves in the supply line.
Check propane tank for gas supply. Refill if necessary.
Pilot will not stay lit after carefully following lighting instructions| Pilot flame does not impinge on thermocouple| Clean pilot hood
Adjust pilot flame at gas valve for proper flame impingement.
Loose thermocouple connection| Ensure thermocouple connection at gas valve is full inserted and tight- hand tight plus 1/4 turn.
Thermocouple reading below 15 millivolts| Disconnect the thermocouple from valve. Place one millivolt meter lead wire on the end of the thermocouple, and the other millivolt meter lead wire on the thermocouple’s copper wire. Start the pilot while holding the gas valve control knob in.

If the millivolt reading is less than 15 millivolts, replace thermocouple.

Thermopile not generating sufficient millivolts| Adjust, if necessary, the pilot flame to envelope thermopile.
Check thermopile connections are properly wired to the gas control valve. Tighten if necessary.
Measure millivolt production with a millivolt meter. Turn remote/ thermostat/wall switch, or ON/OFF rocker switch to OFF. Turn the gas valve control to the PILOT position (pilot should remain lit).

Take millivolt reading at TH-TP and TP terminals on gas valve. Reading should be 350 millivolts, minimum. If reading is less than 350 millivolts, replace thermopile.

Frequent pilot outages| Pilot shield not installed| Install pilot shield.
Pilot safety dropout| Pilot flame is too high or too low. Clean pilot hood and adjust pilot flame for maximum flame impingement on thermopile.
