(in Minutes)
**Unlimited hot water available at specified flow rate.
1. Based on cold start boiler with output listed in Table 1.
2. For minutes of domestic water flow at 115°F, multiply by 1.56.
Table 2: First Hour Ratings for Reduced Boiler Output
1. 180°F Boiler Water
2. 200°F Boiler Water
3. Due to condensation in boiler, reduced output not recommended for PP-80, PP-120, PP-80-DW, and PP-120-DW.
Category IV condensing boilers, such as Peerless Pinnacle, can be used for reduced output.
