GAS LINE CONNECTION
• This fireplace is equipped with a certified flexible pipe located on the right side of the unit. This
flexline is connected to a shut-off ball valve, which terminates in a 3⁄8” female NPT fitting. The ball
valve can be located on the right or left side of the unit, or where the gas supply can enter through
the floor of the unit (see Figure 10). Consult your local authorities codes or the CAN/CGA B 149 (1 or
2) installation code in Canada, or in the USA gas installations follow either local codes or the current
edition of the National Fuel Gas Code ANSI Z223.1.
• The efficiency rating of this appliance is a product thermal efficiency rating determined under
continuous operating conditions and was determined independently of any installed system.
The appliance and its shutoff valves must be disconnected from
the gas supply piping system during any pressure testing where
the pressure exceeds 1⁄2 PSIG (3.45 KPa) or damage will occur
to the valve.
The appliance must be isolated from the gas supply piping
The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1⁄2 psig (3.45 KPa).
Always check for gas leaks with a soap and water
solution after completing the required pressure
test.
TO TEST VALVE PRESSURES
