INSTRUCTIONS FOR OPERATION
1. The installation is not complete until Rating and Lighting Plates are on the boiler and the “User’s
Information Manual” and “Installation Instructions” are hung near the boiler.
2. System should be maintained in good repair. Radiators, baseboard units and/or convectors must be
kept clean.
3. If a radiator does not heat all over, air has probably accumulated and should be vented.
CHECK OUT PROCEDURE
1. After starting boiler be certain all controls are working properly before leaving it unattended. Check to
be sure that the temperature limit control will shut off the boiler in the event of excessive temperature.
2. Check gas tightness of main gas valve when closed to be certain there is no leakage to the burners.
Check all joints periodically for gas leakage. Use soap solution to check leakage.
3. Check the operation of the ignition system safety shut-off device using the following methods:
a. Constant Burning Pilot: With the gas cock knob in the pilot position, extinguish pilot flame and make
certain the gas valve shuts off gas flow to the pilot within two (2) minutes. To relight follow “Lighting
Instructions” (Figure 1).
b. Spark Ignition Systems: With the unit operating, turn off the gas at the inlet shut-off valve upstream
from the boiler. The unit will spark and attempt to relight. If pilot lock-out is provided, the spark will
stop within ninety (90) seconds. To relight follow “Operating Instructions” (Figure 2).
SHUT DOWN CAUSED BY PILOT OUTAGE
1. In the event of pilot outage effecting a shut down of the burners, turn off all electric power to boiler, turn
gas cock knob to “OFF” position. Call a qualified heating service organization or the local gas company.
Have the cause of shut-down investigated and corrected. Boiler can now be re-started. Refer to
“Lighting or Operating Instructions.”

NOTICE
Never leave the boiler unsupervised when it is operating manually. Peerless Boilers can assume
no responsibility for the safe operation of the boiler and other equipment when it is being
operated under emergency conditions.
NOTICE
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.
Do not use this appliance if any part has been under water. Immediately call a qualified service
techician to inspect the boiler and to replace any part of the control system and any gas control
which has been under water.
