Notes: gpm = gallons per minute, lpm = liters per minute,
H/L = head loss, ft = head loss in feet,
m = head loss in meters.
Maximum temperature rise is 35°F (19°C), as shown.
Head loss is for boiler’s heat exchanger only.
N/R = not recommended.

water ow requirements by 15%, and increase the
head loss requirements by 20%.
Power outage, interruption of gas supply, failure
of system components, activation of safety devices,
etc., may prevent a boiler from ring. Any time a
boiler is subjected to freezing conditions, and the
boiler is not able to re, and/or the water is not
able to circulate, there is a risk of freezing in the
boiler or in the pipes in the system. When water
freezes, it expands. This can result in bursting of
pipes in the system, or damage to the boiler, which
could result in leaking or ooding conditions.
IMPORTANT NOTES: Different glycol products
may provide varying degrees of protection.
Glycol products must be maintained properly in a
heating system, or they may become ineffective.
Consult the glycol specifications, or the glycol
manufacturer, for information about specific
products, maintenance of solutions, and set up
according to your particular conditions. Never use
