SAFETY
Safety is the responsibility of each individual who installs, operates or maintains Fireye equipment.
Fireye includes personnel safety as a basic design element of the SureFire igniter.
Observe the following safety instructions prior to performing installation, operation, or maintenance:
WARNING: Hazardous voltage is present and serious injury can occur. See HEI bulletin SF-1.
1.
Use this equipment only for its intended purpose.
2.
Follow only the installation, operation, and maintenance procedures discussed in this publica-
tion and on appropriate drawings.
3.
Ensure that all electrical apparatus used to perform work on this equipment is in good working
order and has been calibrated correctly.
4.
Do not lift or disconnect grounding cables/wires while equipment is energized.
5.
Do not perform modifications on this equipment.
6.
Before opening the HEI power unit's hinged cover, disconnect the electrical supply from the
box. Allow at least 2 minutes for the capacitor to discharge. Exercise extreme care when the
power unit cover is open. Refer to the HEI Service Manual for complete safety instructions for
HEI equipment.
7.
Ensure that no voltage is present prior to disconnecting terminations.
8.
Adhere to safety-related information on all drawings.
9.
Close the manual fuel shutoff valves before performing maintenance or troubleshooting proce-
dures.
10.
Test all fuel gas pipe connections for leaks.
11.
The HEI power pack enclosure and the igniter guide tube should be grounded. (See HEI bulletin
SF-1 for details.)
12.
When removing the igniter assembly from an operating furnace, wear protective clothing and
insulated gloves. While observing the igniter flame through an open observation port, wear a
face shield and protective clothing.
WARNING: Only knowledgeable and qualified technicians should be allowed access to this
system or to its components. The installation, maintenance, and operation of electronic equip-
ment entails several elements of danger. Carelessness can result in serious injury or death
from electrical shock, falls, or improper use of tools and test equipment.
INSTALLATION
A detailed description of the SureFire™ gas igniter installation follows. For job-specific installation
instructions, refer to the appropriate arrangement and installation drawings.
During installation, protect terminal boxes, spark rods, surfaces, round tubes, or any other protruding
devices from accidental bumps or bending forces.
The design of the SureFire™ gas igniter allows the user to weld the guide tube directly to the burner
front plate, if desired. With this configuration, no mount tube is required. When welding the guide
tube to the burner front plate, position the SureFire™ tip 3 inches behind the burner fuel vertical
plane, as a general rule. The igniter guide tube is stainless steel; therefore, a stainless weld procedure
is required.
Optional Mounting Tube
The mounting tube (Figure 4) is affixed permanently to the burner front plate and supports the igniter
assembly. If a suitable mounting tube is not available, one must be installed. However, many retrofit
installations may have a suitable mounting tube. The inside diameter of an existing mounting tube
must provide adequate sliding clearance from the outside diameter of the guide tube, in order to pre-
vent binding of the igniter during installation. In cases where a mounting tube must be installed, per-
form the following steps.
