Installation
Section 5-1: FUEL CONVERSION
n
Verify that your fireplace is compatible with your
available gas type. (Natural Gas or Propane shown
by "N" or "L" in your model number
n
If gas type is not compatible, contact your local
Montigo representative.
n
Conversion kits must be installed by a qualified
service technician.
Section 5-2: GAS PRESSURE
n
Optimum appliance performance requires proper
input pressures.
n
Gas line sizing requirements will be determined in
ANSI Z223.1/ NFPA 54 National Fuel Gas Code in the
USA and CAN/CGA B149.1 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.
n
The manifold outlet pressure is set from the factory
to the appropriate pressure but should be verified.
n
To check pressures, control valves have a provision
to remove a 1/8” N.PT. plug to be fitted with a hose
barb.
n
Montigo requires a service shut off valve be located
in an accessible location to isolate the gas supply.
n
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
n
See Figure 22 for location of gas line access.
n
Flexible gas connectors must not exceed 3 feet in
length, unless allowable within local regulations.
n
Connect incoming gas line to the 1/2"or 3/8" gas
inlet port.
n
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.

Section 5: Installing the Gas Line
Figure 22. 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:
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.
WARNING
When installing the fireplace - gas lines, fittings, accesso-
ries or any other objects cannot impede the proper
movement of the door buckles.
