Section 5: Installing the Gas Line

Section 5-1: FUEL CONVERSION

Verify that your fireplace is compatible with your
n
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
n
Montigo representative.
Conversion kits must be installed by a qualified
n
service technician.

Section 5-2: GAS PRESSURE

Optimum appliance performance requires proper
n
input pressures.
Gas line sizing requirements will be determined in
n
ANSI Z223.1/ NFPA 54 National Fuel Gas Code in the
USA and CAN/CGA B149.1 in Canada.
Pressure requirements are:
Gas Pressure
Minimum inlet pressure
Manifold pressure
The manifold outlet pressure is set from the factory
n
to the appropriate pressure but should be verified.
To check pressures, control valves have a provision
n
to remove a 1/8" N.PT. plug to be fitted with a hose
barb.
Montigo requires a service shut off valve be located
n
in an accessible location to isolate the gas supply.
Only install gas shut-off valves approved for use
n
by the state, province, or other governing body in
which the fireplace is being installed.

Section 5-3: GAS CONNECTION

See Figure 22 for location of gas line access.
n
Flexible gas connectors must not exceed 3 feet in
n
length, unless allowable within local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas
n
inlet port.
Check appliance connection, valve and valve train
n
under normal operating pressure with a commercially
available leak check solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.
