?When the burner is installed in the vestibule of jacketed equipment, it is recommended that
the Automatic Safety Shut-Off Valves be left adjacent to the burner within the vestibule and the
Main Manual Shut-Off Valve be installed outside.
?Run full size pipe or tubing from regulator vent openings to outside of building. Provide no
traps in the vent lines and terminate away from all doors and windows; also make provisions
for keeping rain and foreign objects from entering the vent piping.
?When high supply gas pressure is encountered, as in the case in many industrial plants, the
gas line size can be reduced to allow for a greater pressure drop; however, the size must be
sufficient to deliver burner rating pressure.
CAUTION: High gas pressure supply lines require the proper pressure reducing
regulators. Install a high pressure regulator of the Tight Shut-Off type upstream of the
low pressure regulator. Sized for main gas input, and suitable for the minimum flow
regulating capacity of the pilot.
?The high pressure regulator must be adjustable to 14" W.C. outlet pressure.
?When the gas supply line is about to be put into service it must be tested to insure that it is
gas tight. Use air or inert gas under pressure and test with soap and water to locate leaks.
?Before gas is turned onto the system, a check must be made to see that there are no open
fittings and to make sure the burner main and pilot manual valves are closed.
?After checking for leaks, purge the gas line up to the burner inlet. Purging the air from the
gas supply line at this step will expedite the first light-off.
NOTE: If there is more than 1.0" W.C. differential in the inlet pressure to the burner compared
to when all other gas utilization equipment are off, refer to Section VI.
Burners are approved for use with NATURAL gas or PROPANE gas and should be used only
with the gas specified on the rating plate.
?The gas input should be set at the heating rate determined by the building heat loss and/or
heating plant survey, but not exceeding the rated maximum input of the gas utilization
equipment or Economite burner.
WARNING: Ignition is automatic. Make spark observations into combustion
chamber only with Main and Pilot Manual Shut-Off Valves closed. Confirm that gas
utilization equipment does not contain any accumulated gases. Purge as described in
step 3 below.
CAUTION: Cover plates, guards, and enclosures must be maintained in place at
all times except during maintenance and service.
1. Check the burner piping and valves for gas leaks by applying a weak liquid soap
solution to unions and joints with the gas supply on. Leakage will be indicated by the
appearance of soap bubbles. Locate and correct all gas leaks before proceeding.
WARNING: DO NOT USE OPEN FLAME.
2. Purging the air from the gas supply line at this step will expedite first light-off.
IMPORTANT: Purge outside the building. Do not purge into the gas utilization
equipment.
3. To purge the gas utilization equipment and chimney of any accumulated gases, turn
main Manual Gas Cock OFF, close Pilot Manual Shut-Off Valve, turn burner power on,
and set operating control to ON or thermostat to call for heat. Let the blower run long
enough to accomplish four combustion chamber volume air changes, but not less than
five minutes.
CAUTION:Make sure that the capacity range of the burner, manifold pressure,
and the combustion air shutter setting are suitable for capacity rating of the gas
utilization equipment. Refer to Section VIII and Table 3.
4. RESET the Ignition Control Module by setting the operating control to OFF or the
thermostat below room temperature for at least 30 seconds. See Section XII.
5. Confirm that Main and Pilot Manual Shut-Off Valves are open. Turn main Manual Gas
Cock ON.
6. Turn operating control to ON or set thermostat above room temperature. After the pre-
purge is complete, the pilot should ignite. Whenever the burner pilot fails to light during
the ignition trial, or if the flame is lost during the burner run and is not reestablished
within 15 seconds after the pre-purge, the Ignition Control Module will shut off the
Automatic Safety Shut-off Valves and LOCK OUT.To RESET the Ignition Control Module
Control for restart, de-energize the Ignition Control Module by setting the operating
control to OFF or thermostat below room temperature for at least 30 seconds. If burner
still fails to light, turn it off and repeat from step 4 above. Then if necessary, refer to the
TROUBLE CHART to isolate the problem.
WARNING: Repeated unsuccessful attempts to light will result in accumulated
gases in gas utilization equipment and chimney. To prevent these gases from
reaching an explosive level, periodically purge the gas utilization equipment and
chimney as described in step 3 above.
