2. Verify the boiler and system are full of water and all system components are correctly set for operation.

4. Verify electrical connections are correct and securely attached.
5. Inspect exhaust vent and intake pipe for signs of deterioration from corrosion, physical damage or sagging.
PART 12 – 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 electric power to 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. Set the thermostat to the desired setting.
4. If the boiler
fails to start, refer to the “Troubleshooting” section in the back of
this manual.
B. ADJUSTING THE SET POINT
Before changing the temperature from the factory setting of 180 degrees, you must make sure that none of the thermostats are calling
for heat. The controller will not memorize a program setting while in a heating cycle.
To adjust the boiler temperature simply press in the
{S3} key for three seconds until you see a flashing (C) then an alternate value of
(180). This number is the factory set point of the unit, which is 180 degrees. To change the temperature, simply push either {S1} to
decrease or {S2} to increase the boiler temperature. The temperature of the boiler can be set as low as 50 Degrees or as high 180
Degrees. These ranges are your minimum and maximum boiler temperature ranges.
In addition to changing the temperature, you may also change three more settings in this model: 1. Boiler differential, 2. Indirect setting
(with Vision System option), and 3. Celsius to Fahrenheit measurement. Press
{S3} to get to next value. The boiler differential setting
will appear in the display ch and alternating value of 30. This allows the installer to adjust the activation of the burner based on the
