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 intake piping and exhaust piping for signs of deterioration from corrosion, physical damage or
sagging. Verify intake piping and exhaust piping are intact and correctly installed per Venting Section and
local code.
I. CASCADE SYSTEM
If the boiler is used in a stand-alone configuration, skip this section.
Programming the Master Boiler:
1.
Make sure there is no demand for heat. The boiler cannot be programmed if there is a demand for
heat.
2. Apply power to the boiler.
3. Enter the Installer Menu following instructions in Part 11 of this manual.
4. Verify that parameter 15 is set to 0. This makes the master boiler address 0.
NOTE:
The master boiler
MUST be addressed as 0.
5. Change parameter 23 from 0 to 1. This makes it the master boiler.
6. Exit the installer menu.
NOTE:
The temperature set point of the master boiler must match the follower boiler set point in order for
the system to operate properly.
