Application

Pilot burners provide main burner ignition for standing pilot natural and LP gas systems. Used with a thermocouple to provide

automatic pilot safety control. Used with a thermopile in a self-powered system. See Table 1 for model specifications.

Installation

WHEN INSTALLING THIS PRODUCT…

1. Read these instructions carefully. Failure to follow

instructions can damage product or cause a hazardous condi-
tion.

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 pre-

vent 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’s instructions if avail-

able; otherwise, use instructions provided below.

LOCATION

1. Position pilot burner for easy access, observation, and

lighting. In replacement applications, replace pilot burner

with an identical unit and position new pilot burner in the
same location and orientation as the original pilot burner.

2. Mount pilot burner on main burner. Mounting surfaces

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

3. Mount pilot burner so the ignition 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.

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

impair ignition of main burner.

7. Do not expose pilot burner 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 thermocouple or thermopile.
