• The power and main gas supply must be shut off before
starting the installation.
• Read these installation instructions carefully.

on either side of the valve) on which the VLA will be in
-
stalled.
2. Insert the new o-rings supplied with the VLA in the ap

propriate grooves locate on the back side of the VLA.
3. Mount the VLA to the valve so that the 1” NPT port is ori

entated towards the top of the valve.
4. Secure the VLA to the DMV with the 4 mm screws included
with the VLA. Tighten in a criss cross pattern while torquing
each screw to 45 lb-in.
