Installation
Section 6: Installing the Gas Line
Figure 14. Gas line access. (See Figure 1,
L-H Side View)
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.
Gas line & valve: Exterior Access
The H36PVN is supplied one (1) one exterior access Panel (LH-side
firebox) . This panel is fastened directly to the exterior of the firebox
with sheet metal screws . To remove the panel follow the steps below:

F UEL 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 to purchase a conversion kit .
„ Conversion kits must be installed by a qualified service
technician .
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:
„ 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 .
GAS CONNECTION
„ See Figure 22 below 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.
Pressure Requirements
Gas Pressure Natural Gas Propane
Minimum Inlet Pressure 5 .5" W .C . 11" W .C .
Manifold Pressure 3 .5" W .C . 10" W .C .
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.
