Follower Boilers:
READ THE NOTES BELOW BEFORE PROGRAMMING FOLLOWER BOILERS
•
The boiler addressed as 1 will share its alarm output with the master boiler.
•
If one of the follower boilers has an indirect fired water heater connected to it, the address of this
boiler must be 2 or greater.
•
It is recommended but not necessary to address boilers in the order that they are wired.
•
No two boilers can have the same address.
•
It is not required to use all consecutive address numbers. For example, in a 2 boiler with an
indirect connected to the follower, the follower address would be 2 (address 1 not used).
1. Make sure there is no demand for heat. Boilers cannot be programmed if there is a demand for heat.
2. Apply power to the follower boiler you are working on.
3. Enter the installer menu following instructions in Part 10 of this manual.
4. Set parameter 15 to 1 for the first follower, 2 for the second follower, etc., depending on the boiler you
are programming.
5. Verify that parameter 23 is set to 0. This makes the boiler a follower.
6. Exit the installer menu.
NOTE:
The temperature set point of the follower must match the master boiler set point in order for the
system to operate properly.
PART 9 – START-UP PROCEDURE
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This appliance 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 appliance 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 appliance.
•
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 appliance if any part has been under water. Immediately call a qualified service
technician to inspect the appliance and to replace any part of the control system and any gas control that
has been damaged.
