Insert ignition electrode into the hole of bracket type 27 and fix |
| with attached nut. |
| · |
Check spark gap to target. |
| · |
Spark gap must be between 2.5 and 3.5 mm. |

Aeration |
| IMPORTANT Installer must be a trained, experienced service person. Turn off gas supply before starting installation. An important requirement for the Q349A is that it must be installed correctly. Consult Honeywell application engineers when considering using these devices. Locating pilot burner |
| · |
Position for easy access and observation. |
| · |
Position so that pilot flame will not touch adjacent parts or main |
| burner flames. |
| · |
Position so that pilot flame will ignite main burner when pilot gas |
| pressure just exceeds safety shut--off value. |
| · |
Ensure that pilot flame has an ample supply of dust free air. |
| · |
Do not expose to draughts which will extinguish pilot flame or |
| deflect it from the thermocouple. |
| · |
Pilot burner should not extinguish when main burner is switched |
| "ON" and "OFF". |
| · |
Pilot burner shall be mounted in a preferably upright position. |
Pilot gas connection |
| · |
Square off end of tubing, clean, remove burrs and form it. |
| · |
With orifice assembly and compression fitting in position, insert |
| tubing into target spud until it bottoms and turn compression fitting finger tight. |
| · |
Hold tubing to prevent turning and tighten compression fitting with |
| a wrench about two turns beyond finger tight for 6 mm tubing and about 3/4 turn beyond finger tight for 4 mm tubing to make a pressure tight joint. |
| Do not use jointing compound. Do not bend tubing near fitting after tightening as this may result in gas leakage at connection. |
| Mounting of thermocouple Insert thermocouple tip into thermocouple spud of pilot burner and tighten with the attached nut. |
