LP- 428 REV. 9.2.14
A condensate neutralizer, if required by local authorities, can be made up of lime crystals, marble or phosphate chips that will neutralize
the condensate. This may be done by the installer or you may purchase a condensate neutralizer from HTP (7350-025).
2. The boiler is equipped with a ¾ FPT connection that must be piped to a local drain. It is very important that the condensate line is
sloped downward away from the boiler to a suitable inside drain. If the condensate outlet on the boiler is lower than the drain, you must
use a condensate removal pump, available from HTP (554200). This pump is equipped with two leads that can be connected to an
alarm or another type of warning device to alert the user of a condensate overflow, which, if not corrected, could cause property
damage.
3. If a long horizontal run is used, it may be necessary to create a vent in the horizontal run to prevent a vacuum lock in the condensate
line.
4. Do not expose the condensate to freezing temperatures.
5. It is very important you support the condensation line to assure proper drainage.
H. FINAL CHECKS BEFORE STARTING BOILER
1. Read Startup Procedures within this manual for proper steps to start boiler. (See Startup Report to record steps for future reference.)
2. Verify the boiler and system are full of water and all system components are correctly set for operation.
3. Fill condensate trap with water.
4. Verify electrical connections are correct and securely attached.
5. Inspect exhaust vent and intake piping for signs of deterioration from corrosion, physical damage or sagging. Verify exhaust vent and
intake piping are intact and correctly installed per Venting Section and local code.
6. Ensure both boiler power switches are activated before running the boiler.
I. CASCADE SYSTEM
– MOD CON 1000 AND 1700 MODELS
This double-stacked boiler is shipped factory preset to operate as a common vented cascaded unit. If the double stack is meant to be
used as a common vented cascaded unit and additional boilers are not to be added to the cascaded system, skip this section.
Programming the Master Boiler:
a. Pick one of the bottom boilers to be the Master Boiler.
b. Make sure there is no demand for heat being supplied to the boiler.
c. Apply power to the boiler selected in step a.
d. Enter the system setting program navigation following instructions in Part 9 of this manual.
e. Verify that Cascade Address Function 15 is set to 0. This verifies that the boiler is the master boiler. NOTE: The Master Boiler
MUST be addressed as 0. This establishes the unit as the master in a cascaded system.
f. Set Function 23 to the total number of boilers in the system (4 BOILERS for a four boiler system, 6 BOILER for a six boiler
system, etc.).
g. Exit the Installer Menu.
Additional Connected Mod Con 1000 and 1700 Follower Boilers:
READ THE NOTES BELOW BEFORE PROGRAMMING FOLLOWER BOILERS
If one of the follower boilers has an indirect fired water heater connected directly 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.
Maximum amount of boilers in a cascaded system is eight (8), and equal to four (4) double-stacked units.
a. Make sure there is no demand for heat being supplied to the master boiler.
b. Apply power to the follower boiler you are working on.
c. Enter system settings following instructions in Part 9 of this manual.
d. Set Cascade Address Parameter 15 to 1 for the first follower, 2 for the second follower, etc. depending on which boiler you are
programming based on the above notes. This establishes the boiler as a follower in a cascaded system and enables data to be
transferred as needed for the system to function at full capability.
NOTE: DO NOT select number 8.
NOTE: The top boiler in a MOD CON 1000 or 1700 assembly is factory preset to 1.
e. Ensure Cascade Mode Function 23 is set to COMMON FLUE on all boilers EXCEPT the one configured as the Master Boiler.
This is the factory default in the top boiler in a MOD CON 1000 or 1700 assembly.
f. Exit the Installer Menu.
