INSTALLATION AND OPERATING 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 combination control inlet. Open the
valves in the return and supply piping. Failure to
take these precautions will prevent the boiler from
operating 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 stated instruction up
to this point.
Flame Roll-out Safety Shutoff System
The GB100W gas boiler is fitted with a flame roll-out
switch that detects the presence of hot flue gases in the
control compartment. If something prevents the
combustion products from property passing through the
boiler, the roll-out switch will shut the boiler off. If the
flame roll-out safety system is activated, contact
qualified service agency to correct the problem and
reset the flame roll-out safety switch. Do not attempt to
start the boiler until problem has been corrected and the
switch has been reset.
Never attempt to bypass the flame roll-out safety
shutoff switch for the purpose of operating the
boiler!
The boiler should be inspected and serviced before
each heating season by a qualified service agency. The
boiler flue passages, venting system, ignition
components and the burners should be cleaned and
examined for deterioration due to corrosion. All
operational characteristics of the boiler such as
combustion products, the ignition safety shutoff devices
and proper control function must be thoroughly checked
out.
During the heating season, the owner should check the
boiler and the area around it at least once a month.
Clear away all objects on or near the boiler. Ensure that
there is no discoloration of adjacent combustible
materials due to heat. If there is, IMMEDIATELY call the
installer or a qualified service agency.
