SECTION TWO – Heater Installation

If the temperature di fference is above the maximum,

ther e is not enough water flow to the heater. Check for

obstruc tions in the fi lter, skimmers, and plumbing. If

the water flow is still inadequate, a larger pump is

required.

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.

Above 2,000 feet elevation, derate the heater 4% per

1,000 feet of elevation aa

. That is, at 3,000

feet elevation, derate the heater 12%; at 5,000 feet eleva-

tion, derate the heater 20%. If local authorities allow it,

the Sta-Rite heater only requires to be derated 1.7% per

1,000 feet above sea level.
