SAFETY INFORMATION
FOR YOUR SAFETY READ BEFORE LIGHTING
A. This appliance is equipped with an ignition device
w
hich automatically lights the pilot. DO NOT try to
light the pilot by hand.
B. BEFORE OPERATING smell all around the appli-
ance area for gas. Be sure to smell next to the
floor because some gas is heavier than air and will
settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• DO NOT try to light any appliance.
• DO NOT touch any electric switch; DO NOT use
any phone in your building.
• Immediately call your gas supplier from a neigh-
bor's phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the
fire department.
C. Use only your hand to push in or turn the gas control
knob. NEVER use tools. If the knob will not push in
or turn by hand, DON'T try to repair it, call a qualified
service technician. Force or attempted repair may
result in a fire or explosion.
D. DO NOT use this appliance if any part has been
underwater. Immediately call a qualified service
technician to inspect the appliance and to replace any
part of the control system and any gas control which
has been underwater.
Lighting Instructions
1. STOP! Read the safety information above.
2. Set the thermostat to lowest setting.
3. Turn off all electric power to the appliance.
4. This appliance is equipped with an ignition device
which automatically lights the pilot. DO NOT try to
light the pilot by hand.
5. Remove control access panel. (Galaxy models only.)
6. Turn gas control knob clockwise till knob stops,
continue to "OFF". DO NOT force.
7. Wait five (5) minutes (longer for propane) to clear out
any gas. If you then smell gas, STOP! Follow "B" in
the safety information. If you don't smell gas, go to
next step.
8. Turn gas control knob counterclockwise to "ON".
9. Replace control access panel. (Galaxy models only.)
10. Turn on all electric power to the appliance.
11. Set thermostat to desired setting.
12. If the appliance will not operate, follow the instructions
"To Turn Off Gas To Appliance" and call your service
technician or gas supplier.
To Turn Off Gas To Appliance
1. Set the thermostat to lowest setting.
2. Turn off all electric power to the appliance if service
i
s to be performed.
3. Remove control access panel. (Galaxy models only.)
4. Turn gas control knob clockwise till knob stops,
then continue to "OFF". DO NOT force.
5. Replace control access panel. (Galaxy models only.)
BURNER ADJUSTMENT
A. Adjust gas input rate:
1. Consult gas supplier for higher heating value of gas
(Btu/cu.ft.)
2. Set thermostat high enough so that boiler will remain
on while checking rate.
3. Measure manifold pressure at 1/8" tapping. See
label provided with the conversion kit for the correct
manifold pressure for the gas that is being supplied.
NOTE: Gas pressure may be adjusted by turning
pressure regulator screw on combination gas valve
(turn clockwise to increase pressure, counterclock
wise to decrease pressure).
See page 17 for the input rate of your boiler.
a. Input for PROPANE is approximately at rating shown on
rating plate when manifold pressure is 9

column.
b. Input for NATURAL GAS is approximately at rating
when manifold pressure is 3

" water column, but
should be checked on the gas meter:
Btuh Input = Btu/cu. ft. x cu. ft. metered
in 3 minutes x 20
Example 1
:
For 1000 Btu/cu.ft. gas, this becomes:
Btuh Input = cu. ft. metered in 3 minutes
x 1,000 Btu/cu.ft. x 20
Example 2
:
For 1050 Btu/cu.ft. gas, this becomes:
Btuh Input = cu. ft. metered in 3 minutes
x 1050 Btu/cu.ft. x 20
4. The higher* heating value of gas varies substantially
for different localities. Consult with Slant/Fin’s
Technical Service Dept. for re-orificing procedures
if any of the following apply:
a. Boiler (burner) is overfiring. CAUTION! National
Fuel Gas Code ANSI Z223.1-latest edition does
NOT permit firing at a higher input rate than the
input rate indicated on the boiler rating plate in
order to avoid hazardous conditions such as
explosion or carbon monoxide poisoning.
b. Poor higher* heating value of gas is causing the actual
input to be substantially lower than
the rating plate
indication.
W
ARNING: If you do not follow these instructions exactly,
a fire or explosion may result causing property damage,
personal injury or loss of life.
* “Higher heating” value of gas is commonly known as “heating value”.
