METHOD A: “QUICK” RESIDENTIAL

Table 2 shows some typical applications into which many “residential” applications can be classified. This

procedure will provide satisfactory results most of the time. Where greater accuracy is desired, use Method B.

1) Find the description that best fits the installation and select the Maxi-Therm called for. Also note the

required boiler output under column (f).

2) The Maxi-Therm must be installed with a boiler having an output GREATER THAN OR EQUAL to that

shown in column (f) of Table 2. If the Maxi-Therm is to be used with a boiler having an output LESS

than that shown in Table 2, use Method B.

a) If a new boiler is to be installed with the Maxi-Therm, first find a boiler that will handle the space

heating load alone. If this boiler has an output GREATER than that shown in column (f), do not add

anything to the size of the boiler selected for the Maxi-Therm.

b) If the boiler required for space heating alone has an output LESS than that called for in column (f)

of Table 2, increase the size of the boiler selected to one with an output equal to that shown in

column (f).
