PART 9 – START-UP PROCEDURE
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This boiler does not have pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the
burner by hand.
2. BEFORE OPERATING: smell all around the boiler area for gas. Be sure to smell next to the floor because some gas is heavier than
air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS

Do not try to light any boiler.

Do not touch any electric switch; do not use any phone in your building.

Immediately call your gas supplier from a neighbor's phone. Follow the gas suppliers' instructions.

If you cannot reach your gas supplier, call the fire department.

Turn off gas shutoff valve (located outside of the boiler) so that the handle is crosswise to the gas pipe. If the handle will not
turn by hand, don't try to force or repair it, call a qualified service technician. Force or attempted repair may result in a fire or
explosion.
4. Do not use this boiler if any part has been under water. Immediately call a qualified service technician to inspect the boiler and to
replace any part of the control system and any gas control that has been damaged.
5. The boiler shall be installed so the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during
boiler operation and service (circulator replacement, condensate trap, control replacement, etc.)
Failure to follow these instructions could result in property damage, serious personal injury, or death.
A. OPERATING INSTRUCTIONS
Remove boiler cover. If you smell gas, STOP. Follow listed safety instructions. If you do not smell gas, follow the next steps.
1. Turn on all electrical power to the boiler.
2. If desired, adjust the temperature set point of the boiler. The factory default setting is 180
o
F. If changes are necessary, follow
“Adjusting the Set Point” in this section.
3. On the initial start-up of this boiler, you may note a lock-out code of
F01 . This is a low gas pressure switch lock-out from the factory-
installed low inlet gas pressure switch (located on the left in the 500 and on the right in the 850). You will also see a yellow LED
illuminated under the cover of the inlet gas pressure switch. Once the gas is turned on, reset the gas pressure switch by FIRMLY
pressing on top of the plastic cover over the red reset button. You will note that the yellow LED has gone out. Press and hold the
{S4}
key on the control panel for 4 seconds to begin normal operation.
4. Set the thermostat to the desired setting.
5. If the appliance fails to start, refer to Troubleshooting, Part 11.
B. ADJUSTING THE SET POINT
NOTE: Before you can change the temperature from the factory setting of 180
o
F, make sure none of the thermostats are calling for
heat. The controller will not memorize a program setting while in a heating cycle.
To adjust the temperature of the boiler:

Press the {S3/Program} key for three seconds until you see a flashing “C” alternating to “180” (this number is the factory set
point of 180
o
F).
To change the temperature set point:

Press the {S1/-} key to decrease temperature (temperature can go as low as 50 o F).

Press {S2/+} to increase temperature (temperature can go as high as 190
o
F).
To access additional setting options:

Press {S3} to advance to each parameter listed in the Table 9.
