re Operating
WARNING: If you do not follow these instructions exactly,
a fire or explosion may result causing property damage,
personal injury or loss of life.
A. This appliance is equipped with an ignition device which
automatically lights the pilot. DO NOT try to light the pilot
b
y hand.
B. BEFORE OPERATING smell all around the appliance
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 you gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire
department.
C. DO NOT use this appliance if any part has been under-
water. 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.
OPERATING INSTR
UCTIONS
1. STOP! Read the safety information above on this page.
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. Turn gas control knob clockwise to “OFF”. DO
NOT force.
6. Wait five (5) minutes (longer for propane) to clear out any
gas. Then smell for gas, including near the floor. If you
smell gas,
STOP! Follow “B” in the safety information above
on this page. If you don’t smell gas, go to next step.
7. Turn gas control knob counterclockwise to “ON”.
8. Turn on all electric power to the appliance.
9. Set thermostat to desired setting.
10. If appliance will not operate, follow the instructions
“
To Turn Off Gas To Appliance” and call your service or
gas supplier.
T
o Turn Off Gas to Appliance
1. Set thermostat to lowest setting.
2. Turn off all electric power to the appliance if service is to be
performed.
3. Turn gas control knob clockwise to OFF.
D
O NOT force.
3. 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. Correct
manifold pressure for gas used is printed on boiler
rating plate. NOTE: Gas pressure may be adjusted
by turning pressure regulator screw on combination
gas valve (turn clockwise to increase pressure, coun-
terclockwise to decrease pressure).
a. Input for PROPANE is approximately at rating
shown on rating plate when manifold pressure is
9
1
⁄2" water column.
b. Input for NATURAL GAS is approximately at rating
when manifold pressure is 3
1
⁄2" 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 1000 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 Techni-
cal 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 rat-
ing plate indication.
* “Higher heating” value of gas is commonly known as
“heating value”.
