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 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�
 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.
Section 5-3: Gas Connection
 See Figure 21 below for location of gas line access.
 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�
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 injusy, property damage or death.
DANGER
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.
NOTICE
WARNING
When installing the fireplace - gas lines, fittings,
accessories or any other objects cannot impede the
proper movement of the door buckles.
