Boiler Size Setup
To verify the boiler size selection, a qualified technician should do the following:
1. Check boiler’s rating plate for the model size. For example, if the model number shown
on the rating plate is “PHNTM500C”, the model size is “500”.
2. Verify the altitude at which the boiler is installed.
3. Set “Boiler Type” to match the model size and altitude as shown in Figure 55.
4. Select “Confirm”.
The Boiler Type parameter changes the minimum and maximum modulation settings. This param -
eter is intended to allow a user to set the parameters for altitudes above 2000 ft or in a spare part
control to a particular boiler model. See Figure 55.

If boiler is being installed at elevation above 2000 ft, refer to Appendix A: Instructions for High Altitude
