Line lengths within the shaded areas should not be used when a water heater is the source of heat. When using a boiler for these line lengths, excessive line temperature loss will occur and must be accounted for Supply and return lines must be properly insulated to reduce temperature loss and to prevent freezing when passing through an unconditioned space All lengths include (12) 90° short radius elbows. To adjust for extra or fewer fittings, use the factors in Table 1 Always use full flow ball or gate valves to minimize pressure drop

Notes: 8. Line lengths are based on water only. To adjust maximum line lengths for glycol, divide length by the factors shown in Table 2 9. IMPORTANT: Glycol should never be used in a potable water system 10. All lengths are based on closed loop systems
