Installation
Section 5: Installing the Gas Line
WARNING
When installing the fireplace - gas lines, fittings,
accessories or any other objects cannot impede the
proper movement of the door buckles.
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.

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 Z223.1 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 19 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.

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.
