GV100W BOILER
INSTALLATION & OPERATING INSTRUCTIONS
Direct Ignition Systems
A. Connect a manometer having a minimum capacity of
10 in,
254 mm
, WC to the outlet pressure port of the gas valve.
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 the gas to
dissipate before turning on the electrical power.
B. Understand and follow the operating instructions, on pg.
14 of this manual, that are applicable to the type of ignition
system installed on the boiler.
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 burners should light. If the burners fail
to light the system will make two more ignition attempts. If the
burners light, but go out within 4 seconds, the system will make
three ignition attempts. If the burners have 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 burners in operation, close the manual shutoff valve
in the gas supply line. As soon as the burner flames go out,
open the manual shutoff valve. A normal ignition sequence
should take place.
E. With the burners in operation, interrupt the power to the
control circuit by lowering and raising the thermostat. 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 ignitor should glow and an attempt at ignition take place.
After unsuccessfully attempting to light the main burners 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.
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 14. 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’utilisez 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.
