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.
