GB100W NATURAL OR PROPANE BOILER
INSTALLATION AND OPERATING INSTRUCTIONS
C. Raise the thermostat at least 5 degrees above the
room temperature. The burners should light.
D. A boiler designed for use with natural gas should
have a manifold gas pressure of 3.5" WC. On an LP
boiler, the manifold pressure should be 10" WC. To
adjust the manifold gas pressure, remove the gas
valve pressure regulator cap and turn the regulator
screw to obtain the correct pressure.
E. Test the ignition safety shutoff device, turn the gas
control knob on the gas valve to “PILOT”. The burners
should go out. Extinguish the pilot and wait 3 minutes.
Turn the gas valve control knob to “ON”. There should
be NO gas flow to the main burners with the pilot out! If
gas flow is detected, immediately turn the gas valve
control knob to “OFF” and have the problem corrected.
Intermittent & 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. Read, understand and follow the lighting
instructions contained in 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. For models equipped with an
intermittent pilot the pilot should light and then the
burners. If a direct ignition system is employed, a delay
of approximately 20 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 more
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. After 5 minutes has 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. Momentarily interrupting the
electrical power to the boiler will also reset the system.
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.
BOILER OPERATION
WARNING: Before attempting to operate this
boiler you !MUST! read and fully understand the
lighting instructions in the “For Your Safety
Read Before Operating” section of this manual.
If you attempt to operate this boiler without a full
understanding of it’s ignition system a fire or
explosion may result causing extensive property
damage, severe personal injury or death!
WARNING: Before proceeding read and fully
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.
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.
Continuous Pilot System
A. Connect a manometer having a minimum
capacity of 10" 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. Read, understand and follow the lighting
instructions contained in this manual that are applicable
to the type of ignition system installed on the boiler.
CAUTION: To prevent being burned, take care not to
touch any hot metal parts. Stand clear of the boiler
during ignition to prevent being burned in the case
of flashback.
