GS110 DIRECT VENT BOILER INSTALLATION AND OPERATION INSTRUCTIONS

BOILER SET UP

NOTE: Before starting the boiler, turn off the electrical supply going to it. Make sure that gas is available at the gas valve inlet. Open the valves in the return and supply piping. Failure to take these precautions will prevent the boiler from operation properly.

Fill the boiler and all of the radiation with water. Make sure that the system is completely purged of air.

Review these instructions and make sure that the boiler installation complies with ALL of the instructions up to this point.

BOILER OPERATION

WARNING: Before operating read and understand the instructions contained in this manual. Do not attempt to operate this boiler if it has not been installed in accordance with the guidelines set forth in this manual. Read and fully understand the operating instructions in the “For Your Safety Read Before Operating” section of this manual, pg 22 & 23. Failure to comply with this WARNING could result in a fire or explosion!

Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a location external to the appliance.

En cas de surchauffe ou si l’alimentation de gaz ne peut être coupée, ne pas couper ni débrancher l’alimentation électrique de la ponpe. Fermer plutôt le robinet d’admission de gaz à l’extérieur de l’appareil..

Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control that has been under water.

N’utiliisez pas cet appareil s’il a été plongé dans l’eau, même partiellement. Faites inspecter l’appareil par un tecnicien qualifié et remplacez toute partie du système de contrôle et toute commande qui ont été plongés dans l’eau.

Direct Ignition System

A.Connect a manometer to the pressure ports shown in Figure 20. Make sure that the gas supply piping has been purged of air and that all gas joints up to the gas valve have been thoroughly checked for leaks. Wait at least five minutes for any gas to dissipate before turning on the electrical power.

B.Read, understand and follow the operating instructions, on pg. 22 of this manual.

C.Raise the thermostat at least 5 degrees above the room temperature. A delay of about 30 seconds will take place as the silicon carbide ignitor heats up. Once the ignitor is hot, the main gas valve will open and the burner should light. If the burner fails to light the system will make two more ignition attempts. If the burner lights, but goes out within 4 seconds, the system will make three ignition attempts. If the burner has not lit after the last ignition try, the gas valve will close and the system will go into lock out. DO NOT attempt to reset the system until the ignition system has been inspected and the problem resolved. Once the problem has been resolved and 5 minutes have passed since the last ignition attempt, reset the system by turning the thermostat to it's lowest setting and then back to where it was or by momentarily interrupting the electrical power to the boiler.

D.With the burner in operation the manometer should show 1.9" W.C. manifold pressure. If not, see the BOILER CHECKING & ADJUSTMENT section. Close the manual shutoff valve in the gas supply line. As soon as the burner flame goes out, open the manual shutoff valve. A normal ignition sequence should take place.

E.With the burner in operation, interrupt the power to the control circuit by lowering and raising the thermo- stat. A normal ignition sequence should follow.

F.To test the ignition safety shutoff device, close the manual shutoff valve in the gas supply line. Within 6 seconds of main burner flame extinction, the main gas valve solenoid should close with an audible noise. The igniter should glow and make three attempts at ignition. After unsuccessfully attempting to light the burner the ignition module should lock out.

Open the manual shutoff valve in the gas supply line. Reset the ignition control system by interrupting, then restoring electrical power to the boiler. A normal ignition sequence should take place.
