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

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.
