INSTALLATION

When Installing this Product...
Read these instructions carefully. Failure to follow
instructions can damage product or cause a hazardous
condition.
Check ratings given in instructions and on product to
make sure product is suitable for your application.
Make sure installer is a trained, experienced service

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 is tightened. Gas leakage
at the connection may result.
Follow appliance manufacturer instructions if available;
otherwise, use instructions provided below.
Location
Position the pilot burner for easy access and
observation. In replacement applications, replace the
pilot burner with an identical unit and position the new
pilot burner in the same location and orientation as the
original pilot burner.
Mount the pilot burner on the main burner. Mounting
surfaces other than the main burner can shift, bend, or
warp as the furnace expands and contracts while
operating. See Fig. 5.

BE RIGIDLY POSITIONED
RELATIVE TO MAIN BURNER
Fig. 5. Mount pilot burner on main burner.
Mount the pilot burner so the pilot flame remains
properly positioned with respect to the main burner
flame. See Fig. 6.
Supply pilot flame with ample air which is free of
combustion products.
Do not impinge pilot flame on adjacent parts. Do not
impinge main burner flame on pilot burner.
Do not expose the pilot flame to falling scale that could
impair the main burner ignition.

MAIN BURNER
Do not expose the pilot burner to main burner rollout
while igniting or extinguishing.
Do not expose the pilot flame to drafts that push or pull
the pilot flame away from the igniter-flame rod.
Connect Pilot Gas Tubing
Cut tubing to the desired length and bend as necessary
for routing to the pilot burner. Do not make sharp bends
or deform tubing. Do not bend tubing at control after
compression nut is tightened because this can result in
gas leakage at connection.
Square off and remove burrs from the end of the tubing.
Push tubing into compression nut clearance hole until
tubing bottoms.
NOTE: When replacing SmartValve™ System control,
While holding the tubing all the way in, engage threads
and turn until finger tight.
Using a wrench, turn compression nut one turn beyond
finger tight. Do not overtighten.
Connect the other end of the tubing to the ignition
system control according to the ignition system control
manufacturer instructions.
Wire Pilot Burner to Ignition System Control
Mount the igniter-flame rod assembly on the pilot
M2688A
burner.
Connect the igniter-flame rod assembly keyed plug
connector to its mating terminal block labeled IGNITER
on the SV9500/SV9600.
Use ceramic or plastic standoff insulators as necessary
to prevent cable from contacting metal surfaces.
