Gas connection

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
and rating plate.
• If gas type is not compatible, contact your local Montigo dealer as
this fireplace is NOT field convertible.
GAS PRESSURE
• Optimum appliance performance requires proper input pressures.
• Gas line sizing requirements will be determined in ANSI Z221.3
National Fuel Gas Code in the USA and CAN/CGA B149 in Canada.
Pressure requirements are:
Gas Pressure
Minimum inlet pressure
Manifold pressure
• The manifold outlet pressure is set from the factory to the
appropriate pressure but should be verified.
• To check pressures, control valves have a provision to remove a
1/8" N.PT. plug to be fitted with a hose barb.
• 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.
NOTE: 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 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.
