Air/Fuel Ratio Adjustment

NOTICE: Do not

attempt to adjust the air/fuel mixture by

altering gas or air orifice sizes or by adjusting the gas input
to achieve a particular gas input rate (“clocking the
meter”), as the rate may vary depending on elevation and
local gas heating value. 

Do not

attempt to adjust the gas input outside of the speci-

fied range.

Mixture Too Rich - (too much gas)

Symptoms:

A. CO

2

too high or 

B. O

2

too low or

C. Burner emits a high pitched whine

Cure:

Call Sta-Rite for a 5%-decrease Propane orifice.
Repeat orifice installation, starting at Step 1, Page 2.  
At Step 7, use the 5%-decrease replacement Propane
orifice which should be stamped  as shown:

Mixture too Lean - (not enough gas)

Symptoms:

too low or 

B. O

too high or

C. Burner sounds rough and pulsating or exhaust has a

highly acrid odor.

Cure:

Call Sta-Rite for a 5%-increase Propane orifice.

At Step 7, use the 5%-increase replacement Propane orifice
which should be stamped  as shown:

NOTICE:

If neither correction above produces satisfactory

combustion, consult your Sta-Rite distributor. The air/fuel
ratio is adjusted by replacing the gas orifice with an orifice
of the correct size.

Sequence Of Operation

For detailed information, please refer to Sta-Rite Pool/Spa
Heater Training and Service Manual, publication no.
S5066.
An electronic temperature sensing 

thermistor 

in the mani-

fold adapter inlet controls the heater operation. When the
inlet water temperature drops below the temperature set on
the 

operating control

, the 

burner controller

supplies

power to the combustion 

air blower

through a series of

safety interlocks.

The interlocks consist of 

• the 

pressure switch (PS)

, which senses that the pump is

running, 

• the 

high limit switch (HLS)

, which opens if the heat

exchanger outlet temperature goes above 135°F (57°C),
and

• the 

automatic gas shutoff (AGS)

switch, which opens if

the heat exchanger outlet temperature goes above 140°F
(60°C). 

• the 

stack flue switch

, which opens if the flue gas tem-

perature exceeds 500°F (260°C).

The 

air flow switch (AFS)

senses the pressure drop across

the air metering orifice. As soon as there is sufficient air
flow, the AFS closes, closing the circuit to the 

hot surface

ignition (HSI)

, which ignites the fuel mixture. 

On a call for heat, the blower and HSI are energized. In
about 20 seconds, the gas valve opens and ignition occurs.
The HSI then switches to a sensing mode and monitors the
flame.
