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.
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.
WARNING!
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.
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.
Section 5-1: FUEL CONVERSION
Section 5-2: GAS PRESSURE
Section 5-3: GAS CONNECTION
Optimum appliance performance requires proper input
pressures.
Gas line sizing requirements will be determined in ANSI
Z223.1 National Fuel Gas Code in the USA and CAN/CGA
B149 in Canada.
Pressure requirements are:
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.
WARNING:
An inspection of the explosion relief flappers and door
MUST
be made prior to lighting the fireplace. A faulty
seal on the door gasket and/or explosion ports will result
in products of combustion leaking into the living space
and may result in carbon monoxide poisoning.
WARNING
When installing the fireplace - gas lines, fittings, accesso-
ries or any other objects cannot impede the proper
movement of the door buckles.
