VS8420C,M MILLIVOLT GAS VALVE

Printed in U.S.A. on recycled 
paper containing at least 10% 
post-consumer paper fibers.

Pre-Lighting Checks

1.

Before lighting, smell around the appliance area 
for gas. If the appliance uses LP gas, be sure to 
smell next to the floor because LP gas is heavier 
than air.

2.

If you smell gas, immediately shut off the manual 
valve in the gas piping to the appliance or, on LP, 
at the tank. Leave the building immediately and 
call your gas supplier. If your gas supplier cannot 
be reached, call the fire department.

3.

Do not force the gas valve control knob. Use only 
your hand to turn the control knob.

4.

If the knob does not operate by hand, the valve 
should be replaced by a qualified service techni-
cian.

5.

The gas valve must be replaced if it was flooded 
with water. Call a qualified service technician.

6.

The gas valve is a safety device. It must be 
replaced in the event of any physical damage 
such as bent terminals, missing or broken parts, 
stripped threads, or evidence of exposure to heat.

IMPORTANT

Follow the operating instructions provided by 
the manufacturer of your heating appliance.
