Pilot Adjustment

Periodically check the pilot flames. Correct
flame pattern has three strong blue flames:
1 flowing around the thermopile, 1 around
the thermocouple and 1 flowing across the
burner (it does not have to be touching the
burner).
Note: If you have an incorrect flame
pattern, contact your FPI dealer
for further instructions.
Incorrect flame pattern will have small,
probably yellow flames, not coming into
proper contact with the rear burner or
thermopile or thermocouple.

Gas Pipe Pressure
Testing
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at
#53
test pressures equal to or less than 1/2 psig.
(3.45 kPa). Disconnect piping from valve at
pressures over 1/2 psig.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked
at the pressure test point.
Note: To properly check gas pressure,
both inlet and manifold pressures
should be checked using the
valve pressure ports on the valve.
1) Make sure the valve is in the "OFF" position.
2) Loosen the "IN" and/or "OUT" pressure
tap(s), turning counterclockwise with a
1/8" wide flat screwdriver.
3) Attach manometer to "IN" and/or "OUT"
pressure tap(s) using a 5/16" ID hose.
4) Light the pilot and turn the valve to "ON"
position.
5) The pressure check should be carried out
with the unit burning and the setting should
be within the limits specified on the safety
label.
6) When finished reading manometer, turn
off the gas valve, disconnect the hose and
tighten the screw (clockwise) with a 1/8" flat
screwdriver. Note: Screw should be snug,
but do not over tighten.
