1. Two-stage regulator systems, or twin packing regulators underneath the tank lid, shall be installed on all LPG installations, with twin packing preferred.
2. The first stage regulator shall be installed under the hinged gauge cover supplied with the tank.
a. The atmospheric pressure aperture of the regulator shall point downward.
b. The first stage regulator shall be plumbed to the riser of the yard piping with a flexible riser to allow flexibility should tank shifting occur.
c. The riser from the yard piping shall be located not more than twelve (12) inches from the walls of the tank.

b. The outside hookup to the nipple shall also be schedule 80.
c. This riser shall be a flexible riser pipe and shall be securely supported/braced to the wall approximately ten (10) inches below the regulator to prevent bending of the pipe by lateral snow/ice loads.

b. Installation and maintenance of the snow stake is the responsibility of the LPG user.
7. Propane appliances shall not be permitted in any new installation in an attic or crawl space, effective May 1, 2020, unless a combustible gas detection is built into a system that shuts down the supply of propane in the event of a leak.
8. A combustible gas detector shall be installed in the lowest livable level of any building with an LPG appliance at the time of installation. Maintenance of the combustible gas detector shall be the responsibility of the LPG user.
9. Propane tanks shall be kept clear of snow so that quick access can be made to turn off the propane in emergencies. Keeping snow clear of the tank shall be the responsibility of the LPG user.
B. Submittal to Fire District: The propane company shall submit an LPG permit application and an LPG system plot plan to the appropriate fire district in the following circumstances:
1. After installation of a propane system; or
2. If service is interrupted and a new tank is being set.
The LPG plot plan shall include, but not be limited to, the tank location, tank capacity in U.S. gallons, route of yard piping, location of the riser pipe at the building, property boundaries, an outline of all existing/proposed building on the lot and a depiction of the ridgeline of any building to be supplied with LPG.
C. Submittal to Building Department: After installation by the propane company for new construction and inspection by the appropriate fire district, an approval shall be transmitted to the appropriate Building Department. The Building Department will not issue a certificate of occupancy until receipt of the inspection/approval is received. (Ord. 19-09, 9-30-2019)
