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 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.
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.
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.
