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
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.
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.
Section 5-3: Gas Connection
See Figure 15 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.

Gas line access.
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, accesso-
ries or any other objects cannot impede the proper
movement of the door buckles.
