LOG SET
INSTALLATION
Read the instructions below carefully and
refer to the diagrams. If logs are broken
do not use the unit until they are replaced.
Broken logs can interfere with the pilot
operation.
Log Kit # 431-930 contains the following
pieces:
250
Vermiculite
Vermiculite
Vermiculite
The 3-digit numbers (i.e. 251) are molded into
the rear of each log.
1) Carefully remove the logs from the box and
unwrap them. The logs are fragile, handle
with care -
do not force into position.
2) Sprinkle the vermiculite around the fi rebox
base.
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
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 regu-
lator 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" posi-
tion.
2)
Loosen the "IN" and/or "OUT" pressure
tap(s), turning counterclockwise with a 1/8"
wide fl at screwdriver.
3)
Attach manometer to "IN" and/or "OUT"
pressure tap(s) using a 5/16" ID hose.
INSTALLATION
PILOT ADJUSTMENT
Periodically check the pilot fl ames. Correct
fl ame pattern has three strong blue fl ames:
1 fl owing around the thermopile, 1 around
the thermocouple and 1 fl owing across the
burner (it does not have to be touching the
burner).
Note: If you have an incorrect fl ame pat-
tern, contact your UltraGlow dealer
for further instructions.
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 specifi ed on the safety
label.
6)
When fi nished reading manometer, turn
off the gas valve, disconnect the hose and
tighten the screw (clockwise) with a 1/8"
fl at screwdriver.
Note: Screw should be
snug, but do not over tighten.
