Piping should consist of:
1. A shut off valve approximately 6’ away from the unit.
2. A 1/8” plugged NPT tapping for gas pressure measurement preferably on the manual
shut-off valve (as shown or anywhere between the gas valve and the shut off value).
Note: The manual shut off valve and tapping are NOT part of the SU-4 Gas Burner.
Please make sure you conform to local and state codes.
3. A gas union.
4. A drip pipe.
Caution: The gas valve should not be subjected to more than ½” PSIG. Therefore, the
burner should be isolated during high-pressure gas leak tests. The appliance and its
individual shut off valve must be disconnected from the gas supply piping system
during any pressure testing of that system at test pressures in excess of ½ psig. The
appliance must be isolated from the gas supply piping by closing its individual man-
ual shut off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psig.
