Combustion Area and Vent System
The combustion area and vent system should be visually
inspected before each heating season. The normal
accumulation of dirt, soot, and rust can result in loss of
efficiency and improper performance if allowed to build up.
Accumulations on the main burners can result in the burners
firing out of normal time sequence which is characterized by
an extra loud ignition that can be quite alarming.
CAUTION: If your boiler makes an especially loud
noise when the main burners are ignited by the pilot,
shut off your boiler and call your flealer.
Using a flashlight, proceed as follows to visually inspect the
combustion area and vent system of your boiler.
1. Turn OFF the electrical supply to your boiler and remove
the control access door (if applicable). Turn OFF gas on
self-generating system.
2. Carefully inspect the control compartment main burners,
and pilot areas for dirt, soot, or rust. Then, inspect the
drafthood, flue connection area, and flue pipe for soot and
rust.
i’AT.iTION: If dirt. soul, or rust accumulations arc
found, (.all your dealer and if possible, do not operate
3. Inspect the flue pipe for sag, holes, or disconnection.
WARNING: if holes are found in the flue pipe or if it
has become disconnected, call your dealer before opér­
ât ing your boiler to prevent toxic fume.s from escaping
into your home.
4. Replace the control access door and restore electrical
power to your boiler (if applicable).
5. Start your boiler and observe its operation. If possible,
observe the burner flames to see if they are bright blue. If
you observe_a-suspected malfunction, or that the burner
flames are not bright blue, call your dealer.
NOTE: Burner flames that have a mixture of yellow, orange,
or red flames together with the blue, are not burning gas
efficiently. Your dealer will have to adjust the air/gas
mixture and/or clean the burners.
Before Calling’ for Service
If your boiler does not appear to be performing properly, or
does not operate at all, it may save you the cost of an un­
scheduled service call if you check a few things yourself
before calling for service.
Boiler Fails to Operate
Sometimes a boiler will stop operating because an actual
malfunction occurred; however, it is common for a boiler to
appear to have stopped operating because an easily remedied
situation has taken place.
If your boiler fails to operate, follow these step-by-step pro­
cedures, and proceed only to the next step if theboiler fails to
start:
1. Check to be sure that your room thermostat temperature
selector is set above room temperature.
2. Check to be sure that the electrical power supply to your
boiler is ON.
3. Check to be sure that the manual shut-off valve in the gas
supply pipe leading to your boiler is in the open position.
The valve is open if the lever points in the same direction
the pipe runs, and it is closed if the lever is at a right angle
to the pipe. If the valve is closed, open it, and then follow
the startup procedures on your boiler rating plate.
NOTE: Before proceeding, turn off the electrical power
supply to your boiler and remove the control access door.
4. If you have a manually ignited continuous burning pilot,
be sure that it is burning. If not, see the startup pro­
cedures in this manual. If it is burning, check the control
dial on the gas valve. If the dial is in the PILOT position,
turn it to the ON position, and follow the startup pro­
cedures in this manual.
5. If you have an intermittent ignition pilot, check the con­
trol dial on the gas valve to be sure that it is in the ON
position. If not, follow the startup procedures in this
manual.
6. If your boiler still fails to operate, call your dealer for
service.
When Calling for Service
The product, model, and serial numbers for your boiler, to­
gether with the date installed, should have been, or should
be, recorded in the space provi(ied at the front of this manual.
If the dealer knows exactly what you have, he may be able to
offer some suggestions over the phone to remedy the
problem. This could save you a needless expense and the
dealer a needless visit.
NOTE: If you do not already have a dealer, refer to your
telephone directory or yellow pages for the nearest dealer for
your brand name boiler.
