and Q381A Pilot Burner/Igniter-Sensors

Application

These pilot burner/igniter-sensors provide pilot flame

ignition and sensing in intermittent pilot systems. They
consist of a target type pilot burner with a combination
spark igniter and flame sensor mounted in place of the
thermocouple.

Installation

WHEN INSTALLING THIS PRODUCT…

1. Read these instructions carefully. Failure to

follow instructions can damage product or cause a
hazardous condition.

2. Check ratings given in instructions and on

product to make sure product is suitable for your
application.

3. Make sure installer is a trained, experienced

service technician.

4. After completing installation, use these

instructions to check out product operation.

WARNING

FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH.
Follow these warnings exactly:
1. Disconnect power supply before wiring

to prevent electrical shock or equipment
damage.

2. To avoid dangerous accumulation of fuel

gas, turn off gas supply at appliance service
valve before starting installation and
perform Gas Leak Test after completion of
installation.

3. Do not bend pilot tubing at the control or

pilot after compression nut has been
tightened. Gas leakage at the connection may
result.

Follow appliance manufacturer instructions if avail-

able; otherwise, use instructions provided below.

LOCATION

1. Position pilot burner/igniter-sensor for easy

access and observation. In replacement applications,
replace pilot burner/igniter-sensor with an identical unit
and position new pilot burner/igniter-sensor in the same
location and orientation as the original one.

2. Mount pilot burner/igniter-sensor on main burner.

Mounting surfaces other than the main burner may shift,
bend, or warp as furnace expands and contracts while
operating. See Fig. 1.

3. Mount pilot burner/igniter-sensor so the pilot flame

remains properly positioned with respect to the main
burner flame. See Fig. 2.

4. Supply pilot flame with ample air free of

combustion products.

5. Do not impinge pilot flame on adjacent parts.

Do not impinge main burner flame on pilot burner/
igniter-sensor.

6. Do not expose pilot flame to falling scale, which

could impair main burner ignition.

7. Do not expose pilot burner/igniter-sensor to main

burner rollout while igniting or extinguishing.

8. Do not expose pilot flame to drafts that push or

pull pilot flame away from the igniter-sensor.

NOTE: The Q381A Pilot Burner/Igniter-Sensor is for

horizontal mounting only. Mounting bracket must
remain vertical.
