2. This fireplace is designed to accept either a 3/8"
or 1/2" gas line approved for gas appliances.
Consult local building codes to properly size the
gas supply line leading to a 3/8" reduction.
3. Connect the manual shut off valve to the
previous run gas line.
4. The gas line will be connected to the millivolt
board later in this manual.
WARNING LABEL
IMPORTANT:
NOTE: This 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 psi.
NOTE: This appliance must be isolated from the
gas supply piping system by closing its
individual manual shut off valve during
any pressure testing of the gas supply
piping systems at test pressures equal to
or less than 1/2 psi.
ALL CONNECTIONS WHETHER FIELD OR FACTORY
MADE MUST BE CHECKED FOR LEAKS.
Pressure check taps for both the manifold (outgoing) and inlet (incoming) pressures are located in front of the
gas valve. The right pressure tap is the manifold pressure and the left pressure tap is the incoming pressure.
Follow instructions on page #21 for Model #CSK-335 and page #24 for Model CSK-335-RF for checking these
pressures.
