SECTION TWO – Heater Installation
Heater Water Connections
If the temperature difference is above the maximum,
there is not enough water flow to the heater. Check for
obstructions in the filter, skimmers, and plumbing. If
the water flow is still inadequate, a larger pump is
required.

Live steam hazard. If the burner and the
pump are stopped at the same time, wait at least 15
minutes before starting filter pump to avoid severe
damage to heater.
If the temperature difference is less than the minimum,
the water flow rate to the heater is above 120 GPM, and
must be reduced by installing a manual bypass valve
(Figure 2-18). After installing the valve, adjust the valve
to bring the temperature difference within the accept-
able range, then remove the valve handle or lock it in
place to prevent tampering.

tion, derate the heater 20%. If local authorities allow it,
the Sta-Rite heater only requires to be derated 1.7% per
