Installation
Gas connection
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.
• 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.
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
Natural Gas
Propane
Minimum inlet pressure
5.5in. w.c.
11in. w.c.
Manifold pressure
3.5in. w.c.
10in. w.c.
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 CONNECTION
• The fireplace is supplied with a 1/2 FPT gas shutoff valve
• Connect incoming gas line to the 1/2" gas inlet pipe.
• 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.
When installing the fireplace - gas lines, fittings, accessories or
any other objects CANNOT impede the proper movement of the
fans or door.
When pressure testing the fireplace, Gas line, and input system
follow the appropriate local codes or your area. DO NOT connect
the fireplace to pressures in excess of 1/2lb. This will damage the
gas control valve.
Flexible gas connectors must not exceed 3 feet in length, unless
allowable within local regulations.
