A CHECKUP LIST
Your boiler represents an important investment in your family’s comfort and your home’s value. To keep it in tip-top shape and prevent future
problems, have a trained service specialist give your boiler a professional checkup at least once each year. The following checklist can be used
as a guideline to proper service.
33
Inspect all flue product passages including the burner, passages between the section, and exhaust and intake pipes.
Remove and clean intake air baffle. Inspect all combustion and ventilation air passages and openings.
Inspect electrical wiring, connections, and components for loose connections. Check gas pipes leading to and inside your boiler for leaks.
Clean all drain lines.
Perform an operational checkout to determine whether your boiler is working properly, and if it requires adjustments.
Check all safety controls such as limit switch, pressure relief valve, etc. for proper operation.
Consult the installation instructions for additional service and maintenance information.
If your boiler is not operating or not performing properly, you may save the expense of a service call by checking a few things yourself before
calling for service.
BEFORE YOU REQUEST A SERVICE CALL
IF YOUR BOILER FAILS TO OPERATE
Follow this checklist step by step, advancing to the next one only if boiler fails to operate.
Check thermostat for proper temperature setting.
Is electrical power supply to boiler on?
Is manual shut-off valve in gas supply pipe in open position? (Follow start-up procedures if you open gas line.)
NOTE:
Turn the electrical power to OFF and remove access doors before continuing with the checklist.
Control dial on gas valve in ON position? (Follow start-up procedures if you must reset dial to ON.)
If your boiler still fails to operate, call your service representative.
For your convenience, record the model and serial numbers of your new boiler on the page provided in these instructions. Should you ever
require service, you will have ready access to the information needed by the service representative.
WARNING: CARBON MONOXIDE POISONING AND PROPERTY DAMAGE HAZARD. A failure to follow this warning
could result in property damage, personal injury or death. If holes are found—or if the vent pipe is obstructed or is not con-
nected—toxic fumes can escape into your home. DO NOT OPERATE YOUR FURNACE. Call your dealer for service.
