secondary loop arrangement.) Refer to table below for
minimum boiler circulation rates.
5) Minimum over-pressure at the boiler:
For outlet temperatures up to the maximum of 185 deg F (85 deg
C), a minimum operating pressure of 30 psig (2.1 bar) is required.
6) pH level should be maintained between 8.3 and 9.5

Notes/Limitations:
1. Maximum firing rate determined by ClearFire CFC - Glycol Firing Rate Limitation chart (below).
Maximum high fire blower speed should be set according to chart.
2. Glycol concentration limit of 25%-50%. Minimum required system operating pressure is 30
psig.
3. Maximum system operating temperature of 180 ˚F. Maximum
Δ
T of 40˚.
4. Circulation rates correlate with boiler output based on 92% nominal efficiency.
5. Standard altitude (<1000' ASL). Contact C-B for high altitude applications.
6. Pumps should be sized based on system design
Δ
T and minimum required flow rates.
7. At minimum firing rate, the minimum circulation rate should correspond to the boiler's turndown.
