NOTE: Read steps 1 through 7 below before starting and
compare to the safety shutdown or safety lockout tests
recommended for the intermittent pilot (IP) module.
Where they differ, use the procedure recommended for
the module.
1. Turn off gas supply.
2. Set the thermostat or controller above room tempera-
ture to call for heat.
3. Watch for an ignition spark at pilot burner either
immediately or following prepurge. See IP module
specifications.
4. If module has timed ignition, time the length of the
igniter operation. See IP module specifications.
5. After the module locks out, open gas control knob
and make sure there is no gas flow to the pilot or main
burner. With modules that continue spark until pilot lights
or system is shut down manually, pilot should light when
gas control knob is opened.
6. Set the thermostat below room temperature and wait
one minute.
7. Operate system through one complete cycle to make
sure all controls operate properly.

Maintenance
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH
Improper cleaning or reassembly can cause gas
leakage. When cleaning, be sure that the control is
reassembled properly and perform gas leak test.
Regular preventive maintenance is important in appli-
cations such as commercial cooking, agricultural and
industrial operations that place a heavy load on system
controls because:
• In many such applications, particularly commercial
cooking, the equipment operates 100,000 to 200,000
cycles per year. Such heavy cycling can wear out the
gas control in one to two years.
• Exposure to water, dirt, chemicals and heat can dam-
age the gas control and shut down the control system.
The maintenance program should include regular check-
out of the gas control; see Startup and Checkout section. To
check out the control system, see the appliance manufac-
turer literature. Maintenance frequency must be determined
individually for each application. Some considerations are:
• Cycling frequency. Appliances that may cycle 100,000
times annually should be checked monthly.
• Intermittent use. Appliances that are used seasonally
should be checked before shutdown and again before
the next use.
• Consequence of unexpected shutdown. Where the
cost of an unexpected shutdown would be high, the
system should be checked more often.
• Dusty, wet, or corrosive environment. Since these
environments can cause the gas control to deteriorate
more rapidly, the system should be checked more
often.
If the gas control will be exposed to high ammonia
conditions; i.e., those used in greenhouses or animal barns,
contact your Honeywell sales representative to request a
gas control with corrosion resistant construction.
