Verify ame failure lockout of 60200FR control
1. Install a hose barb tting in the combination gas valve outlet pressure
tap and connect with a hose to a U-tube manometer.
2. Close the main manual gas valve and turn the combination gas valve
knob to ON.
3. Turn on power to appliance and set appliance limit(s) to call for heat.
4. Burner motor will start. The 60200FR will run for its prepurge timing,
then start the ignitor. Approximately three seconds later, the combination
gas valve will open. (The manometer should show almost no pressure,
because the main manual gas valve is closed.)
5. After the Trial for Ignition Period, (TFI) the 60200FR will lockout and
close the Alarm contacts relay.
If lockout does not occur, replace the 60200FR control.
6. Reset the limit to stop the call for heat. Reset the 60200FR from lockout.
Inspect/check system
Before starting the burner and appliance, verify the system has been in-
stalled as directed by this manual and the appliance instructions.
Check gas piping for leaks
Disconnect the burner from the gas supply line if gas line
test pressure will exceed 14 inches w.c. Exposing the burner
combination gas valve to pressure higher than 14 inches w.c.
can damage the valve seat, resulting in potentially unsafe
operation.
You can usually test the gas piping by allowing the line to ll with gas to
main regulator outlet pressure.
1. Shut off gas ow to all appliances connected to the meter.
2. If test pressure will be less than 14 inches w.c., turn the burner com-
bination gas valve knob to OFF. If test pressure will be higher than 14
inches, remove the burner from the gas line by shutting off the main
manual gas valve installed near the burner (per Figure 6, page 9) and
disconnecting the ground joint union. See warning above.
3. Watch the gas meter dial. For a one half cubic foot per revolution dial,
there should be no movement of the dial for at least 5 minutes. For
larger volumes per revolution, increase this time proportionately.
4. If you detect a gas leak, locate the leak with a soap suds mixture and
repair it. Then test the system for leaks again.
Do not test for leaks with an open ame. And do not use
oxygen as a test gas. Either of these could cause an explo-
sion, resulting in severe personal injury, death or substantial
property damage.
Bleed gas line
Purge all air from the gas line. Purge to outside of the building, NEVER
into the appliance or burner.
Leak test near-burner gas piping
If piping near burner has not already been pressure tested, open main
manual gas valve on supply to burner and smell around area for any signs of
gas. Apply a soap suds mixture to all gas piping joints near burner and check
for any leaks. If any leaks appear, repair before proceeding and retest.
Set burner air band
See Figure 8. Loosen air band locking screw. Then rotate band until indicator
points to setting given in Table 1, page 7. Tighten air band locking screw.
The Table 1 setting will probably be satisfactory without change. If the
combustion test indicates a need for more or less air, however, you will
have to adjust the band accordingly.
Check burner and primary control
Inspect burner thoroughly. Verify hinged cover is in place and in good
condition, cover is closed and clamps are tightened. Verify all wiring is in
place and all components are secure and in position.
If the burner fails to ignite, NEVER attempt to manually bypass
the normal sequence of the control, which provides purging
of the combustion chamber.
Do not start the burner if you smell gas or if there may be
gas present in the appliance combustion chamber, heat
exchanger or the vent system. An explosion could occur,
causing severe personal injury, death or substantial property
damage.
During initial start-up, you must be constantly alert for
emergency conditions such as fuel leaks, electrical malfunc-
tions, etc. Familiarize yourself with the location of manual
shutoff valves and switches so you can quickly use them if
needed.
