Section 5: Installing the gas line
Section 5-1: Fuel Conversion
• Verify that your fireplace is compatible with your available gas type.
(Natural Gas or Propane shown by "N" or "L" in your model number
• If gas type is not compatible, contact your local Montigo representative.
• Conversion kits must be installed by a qualified service technician.
Section 5-2: Gas Pressure
• Optimum appliance performance requires proper input pressures.
• Gas line sizing requirements will be determined in ANSI Z223.1/ NFPA

• Montigo requires a service shut off valve be located in an accessible
location to isolate the gas supply.
• Only install gas shut-off valves approved for use by the state, province,
or other governing body in which the fireplace is being installed.
Section 5-3: GAS CONNECTION
• Flexible gas connectors must not exceed 3 feet in length, unless

• Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
• Purge all air out of gas line.
• Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.
NOTICE
When pressure testing the fireplace, gas line, and input system
follow the appropriate local codes for your area. DO NOT connect
the fireplace to pressures in excess of 1/2lb. This will damage the gas
control valve.

After gas line is connected, each appliance connection, valve and
valve train MUST be checked while under normal operating pressure
with either a Liquid Solution, or Leak Detection Device, to locate any

source of leak. Tighten any areas where bubbling appears or a leak is

detected until bubbling stops completely or leak is no longer detected.
DO NOT use a flame of any kind to test for leaks. A fire or explosion
will occur, causing serious injury, property damage or death.
