Millivolt Board Removal / Installation - kozy heat 961 DV Installation & Operating Instructions Manual

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. A gas line knockout is positioned on either side of the fireplace for gas line connection.
4. Connect the gas line to the manual shut-off valve.
5. Connect the flexible gas line (installed on the millivolt board) to the manual shut off valve.
IMPORTANT:
NOTE: The appliance and its individual shutoff 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: The 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 line at test pressures equal to or less than 1/2 psig (3.5 kPa).
Pressure check taps for 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
