The Trinity Ts boiler uses a low mass heat exchanger that requires a minimum rate of forced water circulation
any time the burner is operating (See Table 10-4 for minimum flow rates). To ensure the minimum flow rate is
attained, the boiler must be installed in a “Primary/Secondary” plumbing configuration utilizing “Closely Spaced
Tees” to de-couple the Boiler-Primary loop from the System-Secondary loop(s). See the examples of
Primary/Secondary Loop configurations in Figures 10-2 and 10-3.
System Components – As well as a Primary/Secondary Loop Configuration utilizing closely spaced tees a
properly installed system will include the following major components identified in Table 10-3 as a minimum.
